Wood Deck Costs
Having a wooden deck built can be a great way to increase the overall value of your home while also adding a great outdoor living space in the process. Wood decks come in a variety of styles and sizes, and they can be made of many different types of wood.
- The average reported cost of a new wood deck is $5,620.
- The minimum reported cost is $1,500.
- The maximum cost is an estimate of $10,000.
Several factors can affect the overall cost of a deck, so you should consider the full scope of a project when planning your budget. Make sure you get multiple quotes from decking contractors to compare prices, experience/expertise and overall understanding of your project. Most deck contractors will charge an average rate of $35/sf. Also, remember that materials are purchased per square foot.
Materials will play a large role in the cost of your new deck. The wood you choose, railings, fasteners, lighting and other miscellaneous supplies will determine how costly your deck will be. Choosing stainless steel screws might bump up your cost, but they will also last the lifetime of your deck. Decisions like this will ensure whether you have made a sound investment in your home.
Types Of Wood
There are many types of woods available, some of which are more durable than others. Today, the most common types of wood used for building a deck are:
- Pressure-Treated Wood
- Cedar Wood
- Pine Wood
Pressure Treated Wood
The average cost of pressure-treated wood is $2.35/sf.
One of the more popular materials, pressure-treated wood is known for being among the most affordable options. Pressure-treated wood is great for wet locations as it’s also resistant to rotting. However, decks made of this type of wood generally need to be re-sealed every other year, which can add to its overall costs.
Benefits of Pressure-Treated Wood
- Affordable, compared to other types of wood
- Very strong and durable
- Will last a long time due to durability
- Resistant to insects due to chemical treatment
The average cost of cedar wood decking is $3.75/sf.
Cedar is another common type of wood used for a wood deck. This particular wood has a natural beauty to it that pressure-treated wood simply does not. Cedar is also known for being easy to cut and work with, so this is an ideal material for those who want quick and easy deck construction. Cedar is popular on the West Coast, and it's rot-resistant.
It weathers to a beautiful soft gray. It’s soft and splinters easily. Treating cedar with penetrating sealers will maintain the wood's natural look. Those who choose cedar for your decks should opt for heartwood cedar, which is more durable than construction-grade cedar.
Benefits of Cedar Decking
- Has a vibrant color that adds visual appeal
- Produces natural oils that protect it from moisture, rot, weathering and decay
- Will not warp due to weathering or aging
- Cedar decking is grown from cedar trees in the U.S. and is processed locally
- Much lighter compared to pine or similar hardwoods
The average cost of pine wood decking is as low as $5/sf.
Pressure-treated pine wood will weather to an attractive gray, and it's cheaper than most other decking woods. It comes in different grades, so select the top grade for the decking material. However, because it’s infused with chemicals, it’s susceptible to changes in temperatures and weather patterns, meaning it continually expands and contracts. So, make sure you live in a relatively conservative climate if you want to install this type of decking.
Benefits of Pine Wood
- Very durable
- Considered environmentally friendly
- Easy to work with
- Less labor intensive, resulting in lower installation costs
- Outdoor pine deck can last up to 15 years with proper treatment
The average cost of redwood decking is $7.75/sf.
Redwood is typically the most expensive material used for installing a wood deck. Redwood is the strongest and most lightweight wood available, and it’s also naturally resistant to rotting. Redwood is most common on the West Coast, where prices are still within range. Those who live elsewhere may pay even more to have redwood shipped.
One big value is that it’s highly rot-resistant and does not need to be treated with wood preservatives. Sealers with UV protection will help maintain the wood's natural appearance. Redwood is soft, but weathers to beautiful gray in sunlight. It may darken in damp, wet places and can be lightened by washing with Clorox and water. A pressure hose cleans it very well and restores color. Decks made from redwood can easily last for decades.
Benefits of Redwood Decking
- Has a warm glow and very distinctive appearance
- Extremely durable
- Very resistant to insects and decay
- Redwood decking comes from redwood trees in the U.S.
- Environmentally friendly
The size of the deck can have a large influence on its overall cost. The average size of a deck is about 12x20 feet, but larger decks are becoming increasingly popular as well. Since they require more materials and more time to build, they can be quite expensive.
Homeowners should consider their budgets, the size of land you have to work with and the average size of decks in your neighborhood when determining your deck size.
Many homeowners like to have additional features installed with their decks. One popular option is adding built-in lighting to the deck itself. This is great for people who enjoy spending their nights relaxing on their decks with family or friends. Other popular options include adding built-in storage and seating, a grill for barbecuing or even an automatic misting system to keep the deck nice and cool during hotter months of the year.
These additional features may drive up the cost of the deck but are often a great way to make the most of the living space. Below is a quick breakdown of the cost factors associated with popular wood deck additions:
This is a great option for setting a calm and relaxing mood, while also serving as a safety feature. The average cost of outdoor lighting runs between $8 and $30. The cost of lighting for your deck will vary with light brands and deck size.
These are popular additions because of those chilly nights on the deck. The most common heaters are post heaters that can be placed anywhere on your deck. The average cost for outdoor heaters can vary between $100 and $300 depending on style, brand and output. Another great option is to install an outdoor fireplace. This option is not only functional and will keep you warm, but it will also make that time outdoors more special. The average cost to install an outdoor fireplace is between $1,400 and $20,000.
Misting systems are very popular additions to decks that are exposed to too much heat or for homeowners that live in warmer areas of the country. Misting systems can be as low as $25, but the average cost for an outdoor misting system generally runs from $100 to $150. The impact on your water bill is comparable to watering your lawn.
Seating is a must for any deck. From easy options like plastic patio chairs to furniture that feels like you’re sitting in your living room, the cost of your outdoor furniture will vary. For a set of four chairs and a table, the average cost for outdoor seating is around $350. If you want to go the extra mile, a full set of chairs, sofa, end tables and a coffee table will cost you close to $4,000. Finally, an awning would cost between $700 and $1,000.
If you’re looking to do some cooking and grilling on your deck, the cost options for an outdoor kitchen will vary. Mainly, the biggest cost factors will be the size of the outdoor kitchen and the appliances you prefer. Depending on the appliances chosen, the average cost for a basic outdoor kitchen will run you a couple thousand dollars. That’s not including a grilling set and other necessary tools for cooking and barbequing.
Homeowners who wish build a deck should find a contractor who specializes in this type of work. He or she will then be able to come out to one's home, assess the situation and give you a number of possible deck options in terms of price and features. This is a great way for homeowners to choose the deck that is right for you, both in terms of your budgets and you desires. It’s never a bad idea to compare deck prices among a few different competitors to ensure a reasonable price.
Homeowners should note that while building a deck is not cheap, it’s one of the best home improvement projects to add value to a home and yield high returns over time. Homeowners who do not plan on selling their homes anytime soon can still enjoy the benefits of having a wood deck for outdoor entertainment and additional living space.
Wood Deck Maintenance
Any homeowner considering installing a deck should be aware that there will be some maintenance involved to keep the deck in good shape. This maintenance includes:
- Staining the deck to keep it looking like new
- Sealing the deck to prevent moisture damage and splintering
- Inspect for signs of cracked or rotting deck boards
- Replacing wood slats as needed over time
A bit more work is required for those who wish to have a stain on their decks. In general, homeowners should wait until the time of the first deck sealing to stain the wood. This will give it time to dry out and settle from the initial construction, which is important for the wood to properly take the stain. Staining should always be done prior to sealing and can be done by the homeowners themselves or by hiring a team of professionals. Those with larger decks should hire a contractor as the process can be very time consuming otherwise.
Wood Deck Repair
As your deck begins to age, you’ll notice the small splits and minor warps. This is natural and will happen to even the toughest of woods. Homeowners can do some repairs, while others should be left to a local contractor. More serious problems may show that your deck is reaching its final days and will need to be replaced or restored.
Minor repairs such as a rot on a board or a nail that has popped up can be done yourself. Some damages that appear more serious will need to be checked by a contractor. Such examples include:
- Fasteners that are loose or no longer hold in place
- Soft boards due to water damage
- Visible rotting
- Loose railing posts
- Loose boards on staircase
These are damages that put the occupants at risk. If you feel unsure about the safety of your deck, have a contractor inspect it. An experienced contractor will be able to spot questionable areas and tell you what/why it’s damaged, as well as what to do in the future to avoid the damages.
How much these repairs will cost all depend on the original cost of your deck. Some decks may need to be completely replaced, while others may need a couple boards replaced. In any case, there are a few factors you must consider before work begins:
- Disposal: If you chose pressure-treated wood for your deck, you have to get rid of it properly due to the chemical treatment. The cost for disposal might be higher due to this.
- Permits: Replacing certain parts of your deck, like a railing, might require additional permits. For you, a deck is just an outdoor space to sit and hang out with friends and family. For an inspector, this is an addition to your home and is treated as such. If any lights, electricity, or gas are going to be repaired or replaced, then an additional permits is likely required.
- Demolition: Most contractors will charge extra for this service. The average cost for demolition is between $5/sf and $15/sf. If your wood and other materials are in good shape, the cost may be reduced because your contractor can re-use these materials for another job.
Taxes & Insurance
Your new wood deck project is an addition to your home, which also means it’s an addition to your property value and property taxes. While you’re planning your deck project, make sure you plan for this added value and added cost on your taxes. How much will be added all depends on the total cost of your wood deck project. That’s why it’s important to consider in the planning stage of your project.
While in the planning stage of your wood deck project, make sure you check your homeowner’s policy and see if a deck is covered. When you find the right contractor for your deck, ask for a certificate of insurance and make sure any permits needed are obtained. Ask your contractor to arrange a certificate of occupancy so that your deck is certified safe for a certain number of people.
DIY Or Hire A Contractor?
Building your deck yourself is a cost-effective option when looking at this project, but the real question is, can you handle it? There are a few factors that come into play when deciding to build a deck yourself: Which permits do I need? Do I have the correct insurance coverage? Do I have the necessary requirements for the stairs and railing? These can all factor into your DIY deck. If you do end up building your deck and any part of it becomes faulty, then any liability, injuries or damage fall on you.
The safest option when it comes to building a wooden deck is to hire a professional. This may be more expensive than building it yourself, but hiring a skilled professional can give you peace of mind knowing your deck is being built properly and up to code.

How Much Does It Cost to Build a Deck?
Adding a deck is a great way to expand your living area at a modest cost per square foot. According to the “Cost vs. Value Report” from “Remodeling” magazine, the national average cost to have a basic, all-pressure-treated wood deck professionally built is $31 per square foot. Compare that to the national average cost for a two-story addition of about $210 per square foot, and outdoor living sounds really attractive.
But that $31 per square foot is only a reference point. Depending on how simple or extravagant your tastes are, and how much DIY work you’re willing to do, the cost of building a deck can vary a whole bunch.
Obviously, the size of your deck is a big factor in determining costs. Smaller decks cut down not only on the amount of decking you’ll use, but also the number of posts, piers, joists, screws, and metal connectors. Smaller decks take less time to build, too. So if you need to cut costs from your proposed deck project, try shaving a few square feet off the design.
Building a Deck02:48
In this series, Chip Wade shows you how to build a deck from the ground up.
The overall design affects cost, too. A square or rectangle deck is straightforward. Start adding curves, multiple levels, and herringbone decking patterns and you can tack another 30% to 50% onto your costs.
Do-it-yourself labor can be a big money-saver. A competent DIYer is likely to cut that $31-per-square-foot cost in half. The tradeoff is time — if you’re not building decks for a living, you’re likely to take three times longer to build your deck than a pro.
Your choice of materials is another variable that affects the cost of building a deck. Here are some common decking material and their prices:
Pressure-treated wood is generally the cheapest decking material you can find, but it’s usually made from inferior-grades of wood. $1.50 to $2.50 per square foot.
Cedar is widely available and makes for beautiful decking. $3.75 to $5 per square foot.
Redwood decking is generally available in the West but can be harder to come by east of the Rockies. $6 to $8 per square foot.
Composite and other synthetic decking has the advantage of being virtually maintenance-free. Many brands have a high recycled content. $7 to $10 per square foot.
Ipe and other tropical hardwoods are the luxury choice and they’ll last up to 50 years. Because ipe is so hard, installation goes slow. $8 to $12 per square foot.
The really good news about establishing your deck budget is that there are many free deck cost estimators available online. Put in your dimensions, choose your materials, add a zip code and voila! You’ll get a good idea what your deck will cost in your area. Websites of deck part manufacturers and home improvement centers are good places to find deck cost estimators, some even have deck stair calculators, too. It’s a great way to kick off your project with a budget firmly in hand.
Cost to Build a Deck – 2021 Average Prices & Cost Calculator
How Much Does a New Deck Cost?
Often, adding a deck is significantly less expensive to add outdoor living space with a deck than it is to add an addition to your home.
Adding a deck can add significant value to your home as well. The average cost of building a deck is about $20 – $50 per square foot, and most spend $4,000 to $12,000 to build one.
There are several things to consider when establishing a budget for your project to help get a more precise estimate.
How Much Does a Deck Cost
Several factors contribute to the cost of a deck, and they must be considered to estimate the cost. Perhaps the most important factor is the size. The actual square footage directly affects how much materials are needed and thus the cost. Decks are often estimated by the square foot, however there are other very important factors to consider.
Height is another factor that affects the cost of building a deck. The higher elevation adds additional danger and complexity to the installation. Decks that are high in the air also require extra post length.
Decks that are a story off the ground need a larger set of stairs and longer posts than a deck that is near the ground. Stairs are a costly addition to a deck, so consider that adding them will increase the overall cost.
Adding stairs to a second-story deck will increase the cost by about $1,500 on average.
Deck railings are another cost factor, and choosing a more expensive railing option will affect the cost of the deck. For example, a fine clear glass rail will be significantly more costly than a pressure treated pre-fabricated rail. The cost of the railing includes the cost of posts, rails, and balusters.
If you’re estimating the cost of a railing check out our baluster calculator.
The choice of flooring is a major factor when estimating the price of a new deck. Wood decks often cost $45 per square foot while composite decks often cost $62 per square foot. The cost of the flooring material itself is not that much of course, and will vary depending on the type of material you choose to use.
Some materials also require less maintenance which helps offset the cost over the long run. See our deck flooring calculator to estimate how much flooring material you’ll need for your deck.
Pressure Treated Flooring
Pressure treated wood decking costs on average $2 per square foot. Pressure treated wood is cost effective, long-lasting, and naturally insect resistant. They do require additional maintenance and frequent staining, and need galvanized fasteners to prevent corrosion.
Cedar wood decking costs $4 per square foot on average. Cedar is also cost effective, beautiful, long-lasting, and naturally insect resistant. They do require additional maintenance and frequent staining, but do not need galvanized fasteners.
Redwood wood decking costs around $7 per square foot. Redwood is beautiful, very long-lasting, does not warp, and accepts stain very well. Redwood is quite a bit more expensive than pressure treated or cedar.
Composite decking usually costs around $8 – $10 per square foot. Composite is very durable, looks great, and requires virtually no maintenance. Composite is on the more expensive end of material choices, but since it does not require stain there is some cost savings over the long run. There are many types of plastic and composite decking that vary in cost.
The design of the deck will determine how much labor is needed to install it. More complex designs take more time to install and will thus cost a bit more. Complex designs require more planning and layout, more cuts, and may have more wasted material.
The area you live in will also impact the cost of building a deck. Labor costs vary by region, and labor amounts to the majority of the cost of a deck.
Code requirements also vary by region, which will impact the amount of structure needed for the deck. For instance, colder climates require larger footings that need to be buried below the frost line, which increases the cost.
If you need to remove your old deck there will be some costs involved. Removal can cost anywhere from $500 – $1000 on average. You may be able to do some of this yourself if you choose, but it can be a very difficult job. Also consider that the removed waste material will need to be disposed of.
Estimating Deck Costs
After you have considered the above factors you may be pretty close to figuring out how much your deck will cost. There are some other factors to consider to get a detailed estimate such as footings, inspections, lighting, heaters, and other features.
Consider requesting a professional estimate for your project. Our professionals can give you an accurate estimate and more specific pricing for your local area. Also consider that the information above is very general and your deck costs may vary depending on your home and your location.

How Much Does It Cost to Build a Deck?
Decks have a range of building costs per square foot. This is because it can be made out of many materials. Various materials have different costs, and some materials can be more difficult to work with than others. This can make the cost to build a deck cost more in labor. For example, pressure-treated pine costs around $2 a square foot but needs to be painted or stained, which increases labor costs. Composite decking, costing $8 to $15 a square foot, is easier to work with and may have lower labor costs.
The average cost per square foot to build a deck is between $14 and $44, depending on the material, deck type, and geographic location. Costs can be higher for complex builds and materials or lower for simple platform decks.
Cost to Build a Deck by Size
Decks can be built in a vast range of sizes. The most common size is 16’x20’ or 320 sq.ft., but decks can be much larger or smaller, depending on your space and needs. Sometimes, the size of deck that you choose will be dictated by the amount of area you have. Other times, the features that you want or the shape of the deck you’re planning on can influence the overall size. Because decks are often priced per square foot, the larger the deck that you build, the higher your total costs will be, regardless of style or material. The following is a list of average cost ranges for some of the most common deck sizes:
|Deck Dimensions||Square Feet||Average Cost Range (Installed)|
|8’ x 10’||80 sq.ft.||$1,120 - $3,520|
|12’ x 12’||144 sq.ft.||$2,016 - $6,336|
|10’ x 16’||160 sq.ft.||$2,240 - $7,040|
|10’ x 20’||200 sq.ft.||$2,800 - $8,800|
|12’ x 20’||240 sq.ft.||$3,360 - $10,560|
|14’ x 20’||280 sq.ft.||$3,920 - $12,320|
|16’ x 20’||320 sq.ft.||$4,480 - $14,080|
|20’ x 20’||400 sq.ft.||$5,600 - $17,600|
8x10 Deck Cost
A deck measuring 8’ x 10’ or 80 sq.ft. in total ranges from $1,120 to $3,520. At the lowest end, this assumes either a platform deck or a very simple raised deck made of pressure-treated wood. At the highest end, this assumes a deck made of either metal or very high-end exotic hardwood 2 with a roof. Decks this size are small enough to be added nearly anywhere on a house or in a yard.
12x12 Deck Cost
A deck measuring 12’ x 12’ or 144 sq.ft. costs $2,016 to $6,336. These prices include a range of different styles. This may mean a simple platform deck at the lowest end and an aluminum raised deck at the upper cost range. Costs also vary depending on the location, deck shape and style, and materials used.
10x16 Deck Cost
A deck that measures 10’ x 16’ or 160 sq.ft. in size ranges from $2,240 to $7,040. This includes different deck styles and materials. At this size, a deck is large enough to include built-in 5 benches or an eating area, increasing total costs through different decking layouts and designs. These can also be platforms or raised decks and may have roofs as well.
10x20 Deck Cost
A deck that measures 10’ x 20’ or 200 sq.ft. costs $2,800 to $8,800. Decks that reach these dimensions may be two or multi-story, or they can be an oversized platform or freestanding deck. This size has many possibilities for adding areas like hot tubs and entertainment areas to the deck, which may require reinforcing the decking. You can also use a range of materials and building styles, which accounts for the varying costs.
12x20 Deck Cost
A deck measuring 12’ x 20’ or 240 sq.ft. in size ranges from $3,360 to $10,560. These decks are large enough to wrap around the side of a building, have two or more levels 16, or be a large platform-style deck that encompasses a large part of a yard. These decks often fit entertainment areas and handle different decking patterns to define separate areas. These can include simple decks built from metal and more elaborate decks built from wood.
14x20 Deck Cost
Decks that measure 14’ x 20’ or 280 sq.ft. in size cost $3,920 to $12,320. These decks have varying levels 16 or wrap around the side of the house. At this size, it is common to have at least part of the deck covered or roofed for shade, such as in eating or entertaining areas. You may need to have larger footings 7 to hold the weight, particularly if you have many built-in 5 areas or include entertainment options like a hot tub. The costs range depending on the material and style.
16x20 Deck Cost
Decks measuring 16’ x 20’ feet or 320 sq.ft. in total size are the most popular deck size in the U.S. They have a total cost range from $4,480 to $14,080, depending on the deck material and style. These decks can be configured to have separate areas for relaxing, eating, and entertaining. Because of this, it is common for decks of this size to have at least partial covers or roofs, as well as to be raised or have two or more levels 16. They are most commonly made of wood or composites at this size, but they can be metal as well.
20x20 Deck Cost
A deck that measures 20’ x 20’ or 400 sq.ft. is large enough to wrap the side of a home, have a large expanse for entertaining, or have different levels 16. This size has a cost range of $5,600 to $17,600, depending on the style and material. At this size, if the deck is raised, it may need reinforcing or to have additional footers 7 put in for stability. If you plan on adding a hot tub, you need additional reinforcement. Platform decks of this size can be good options for housing an outdoor kitchen or living area.
New Deck Cost by Material
There are many materials to use for a deck. Many people opt for wood or composite, but there is a wide range of materials that fall into those two categories. You can also use other materials, such as metals. Each material has costs and attributes influencing the appearance and long-term performance:
|Material||Average Costs per Square Foot (Material Only)|
|Pressure-Treated||$2 - $5|
|Steel||$3 - $6|
|Redwood||$5 - $35|
|Ipe||$7 - $9|
|Fiberglass||$8 - $15|
|Composite||$8 - $16|
|Vinyl||$9 - $16|
|Mahogany||$10 - $15|
|Aluminum||$12 - $13|
|Cedar||$15 - $30|
Pressure-Treated Deck Cost
Pressure-treated wood is one of the least expensive materials used to build a deck. The wood is usually pine but can be other softwoods. The wood is soaked in a preservative - usually CCA (carbon copper arsenate) - and put under pressure, driving the chemicals inside and preventing wood rot. Pressure-treated wood requires galvanized screws and fasteners to prevent rusting. The wood may have a greenish tone to it from the treatment. It needs to be painted or sealed during installation. The cost of a pressure-treated wood deck is around $2 to $5 a square foot for materials.
Steel Deck Cost
Steel is not as common as wood but can create modern-looking decks. Steel tends to be hot underfoot, which can make it uncomfortable on sunny days. It can also be difficult to work with, and you need to find a steel deck specialist. While the cost of steel decking is relatively low, you may find that you need to pay much higher costs for installation because of the increased labor. The cost of steel is volatile, so get the project priced out before you build to get the most accurate costs. Expect to pay between $3 and $6 per square foot.
Redwood Deck Cost
Redwood is uncommon for decking, but if you do not want pressure-treated wood, redwood is a good option. Redwood is rot and insect-resistant, so it does not require chemicals to make it last for years. It ranges in color, durability, and price, depending on if you use sapwood or heartwood and where the redwood is coming from. The farther the material needs to be shipped to you from the forest, the more it costs. Redwood in California costs much less than redwood in New Jersey. The cost per square foot for redwood ranges from $5 to $35 a square foot.
Ipe Deck Cost
Ipe is a popular exotic hardwood for decks. It has a rich, dark color and is so dense that it resists burning nearly as well as concrete. Ipe is prized for its longevity. It can last for years with little maintenance and show no signs of wear. Because it is so incredibly hard and dense, however, it can be very difficult to work with. Installers are more likely to charge twice for the installation labor of ipe than for pressure-treated wood. Ipe costs between $7 and $9 a square foot on average.
Fiberglass Deck Cost
Fiberglass decking is a subtype of composite decking. The decking is a blend or composite of materials. Sometimes, the materials are used throughout the plank. At other times, the core is made of a wood-pulp blend, while the exterior wrapper is something more durable. Fiberglass decking contains fiberglass particles in the outer wrapper or core. Fiberglass decking is considered low-maintenance and durable. It may get hot underfoot, depending on the manufacturer. The material costs between $8 and $15 a square foot on average.
Composite Deck Cost
Composite decking refers to any blend of materials that may include plastic, wood, wood pulp, fiber cement, or vinyl in a deck plank or railing. Composite decking is made to look like wood decking but does not require the same level of upkeep. Some composites are water-resistant, while others may swell when not installed properly. Some get very hot underfoot, while others stay cool. But most composite decking is easy to install and can last for years with little-to-no maintenance. Expect to pay $8 to $16 a square foot, depending on the material.
Vinyl Deck Cost
Vinyl or PVC decking is a subtype of composite decking. Vinyl decking usually has a vinyl exterior around the standard composite interior, but some decking planks may use one material throughout. Vinyl decking is very low-maintenance, water-resistant, and does not need painting. It does not get hot underfoot, making it good for sunny decks. It costs between $9 and $16 a square foot on average.
Mahogany Deck Cost
Mahogany is another hardwood that gets good results on decks. Mahogany is a dense, durable hardwood with a rich color that holds up well long term. This is another material that can increase the labor cost significantly because it is dense and difficult to work with. Cutting, nailing, and fastening mahogany takes longer than other woods, so the cost of installation reflects that. Mahogany ranges from $10 to $15 a square foot on average.
Aluminum Deck Cost
For those who want a metal deck that does not get as hot in the sun as steel, aluminum is a good choice. Aluminum is a lightweight metal that can create a contemporary-looking deck. It is easier to work with and install, but it can be very noisy. It makes echoing and pinging noises when walked on and struck, and it dents easily. But it is flame and insect-resistant and does not rot. Aluminum decks cost around $12 to $13 a square foot for the material.
Cedar Deck Cost
Cedar is a popular material for the home’s exterior, including the deck. Cedar is naturally rot and insect-resistant, and it is easier to work with than most hardwoods. Cedar does not need to be stained or painted, but if you do, you need a primer first because cedar “bleeds” through the paint. Cedar’s price has increased recently because of availability and continued popularity. Expect to pay between $15 and $30 a square foot on average.

Price of a New Deck by Construction Style
Decks can be built in many styles. Most people install their deck attached to their homes, but this is not the only way. Decks can be installed at ground level, raised, covered, or have multiple levels. Because of the many types of decks, they range in costs.
While the average size of a standard attached deck is around 320 sq.ft., every deck style can have a range of sizes that suits them best. Below are the average cost ranges to build each style of deck per square foot.
|Style||Average Costs per Square Foot (Installed)|
|Platform||$10 - $30|
|Freestanding||$10 - $30|
|Raised||$25 - $45|
|Two-Story||$28 - $55|
|Multi-Level||$28 - $70|
|Covered||$30 - $80|
Platform Deck Cost
Platform decks are built on the ground without raised pillars or footings. They are raised up, about the height of a single step, to increase the elevation and area definition, but they do not attach directly to the home. Platform decks are a nice alternative to a patio and are ideal for holding hot tubs and entertaining. They can be made of any decking material but are most often built of wood or composites. They cost around $10 to $30 a square foot to build, depending on the material.
Freestanding Deck Cost
Freestanding decks or floating decks are a type of platform deck. They are not attached to the house and are often slightly away from the home. While some platform decks are in the patio area, a freestanding deck is usually located farther away. They may have a path or no link to the home at all. Floating deck costs are similar to other platform decks, $10 to $30 a square foot, depending on the material.
Raised Deck Cost
A raised deck is the most familiar deck. It is raised up to the second story on pillars and is attached to the house. This type of deck usually has concrete footings beneath the pillars for support. The deck is also physically secured to the house, usually with support brackets. This makes this deck style more complicated than a platform deck. The average cost to build this deck is between $25 and $45 a square foot, depending on the material.
Two-Story Deck Cost
Two-story decks are uncommon, but they can be beneficial for those who host often. A two-story deck may start at ground level with a platform or one story up like a traditional raised deck. The stairs connecting the two levels are usually on the exterior or one side of the deck. There is usually an entrance to the deck at each level directly from the house. Because this type of deck requires more support and stairs, it costs more to build at $28 to $55 a square foot on average.
Multi-Level Deck Cost
Multi-level decks are also less common and can include two or three-story decks. They usually follow the same basic styles and designs as a two-story. Each level you raise the deck increases the amount of supports needed and cost. So, there is a wider range of associated costs. The average range to build a multi-level deck is $28 to $70 a square foot, depending on the material and deck’s size.
Covered Deck Cost
There are many ways to add shade or rain protection to your deck, including a cover or roof. Decks can be topped with a pergola, which adds dimension, definition, and varying degrees of shade, or you can build a full roof with various roofing materials. If you build a full roof, you can also finish the underside like you would a porch or leave it bare. With all these variations and options, the cost to build a covered deck has a wide range of costs. Costs range from $30 to $80 a square foot, depending on the material and style.
Decking Cost by Pattern
The part of the deck that you stand on is the decking. Decking can be made of many materials, but it is usually sold and installed in planks. These planks can be laid out in straight lines running lengthwise or horizontally across your deck, and in some cases, laid out in a mix.
There are several other patterns to lay your decking in as well. Any pattern other than a straight pattern where the boards are laid all in one direction from side to side increases your project’s cost by 15% to 20% for complex patterns. This is because you need additional decking material to complete any pattern, and it takes your installer longer to lay the decking, resulting in higher labor and material costs.
Decking patterns are a great way to improve your deck’s appearance because each pattern can complement different architectural styles.
A parallel pattern lays decking planks in straight parallel lines. They can be laid to start at the house and move away or run parallel to the house. The direction is influenced by two things. First, it costs less when using full planks in one direction without relying on cut and pieced planks. Second, if you have a very thin deck, run the planks horizontally to make it appear wider. There is no increase in installation costs for this pattern.
Diagonal Deck Pattern
Diagonal deck patterns run at a roughly 45-degree angle across the deck. This can be a good way of making thinner decks look wider because it draws the eye outward, pushing the deck visually. It is also a more decorative way to lay your planking than in simple straight lines. Diagonal decking patterns can also highlight certain areas. For example, if you have an eating area, you can switch the pattern in this section to separate it. Because of the extra labor and cuts involved, this pattern increases costs by roughly 15%.
A true parquet is a group of planks fitted into a square and installed one square at a time. There is no singular parquet pattern. The squares in a parquet can make up many patterns, including chevrons, diagonal squares with straight planks, or planks run in two directions within one square. If you want to give your deck the look of a parquet floor, cut the planks into 12-inch lengths and arrange them into squares. This can be a time-consuming pattern to create, depending on the final arrangement. Expect installation costs to be roughly 20% higher on average.
Herringbone and chevron deck patterns are decorative ways to dress up your deck and give it a more formal appearance. In a herringbone or chevron pattern, the planks are laid at angles to one another to create a repeating pattern. This type of decking has a heavy visual movement. Like the diagonal pattern, it is a fun way to create a visual break in the deck, such as laying it in the bar or eating area. You can also lay the pattern over the entirety. Herringbone patterns increase your costs by roughly 15% with material and labor.
Any parquet pattern or countless others can be considered a custom pattern. With a custom pattern, you must work with your installer to find out what their comfort level is. Ask if they have done patterns before, and request to see a portfolio of images. They may design custom patterns for individual decks or work with you to create your own. You can also show them images if you find a pattern that works for you. This includes inlaying different woods, such as mahogany to create a darker area, and creating a series of boxes that shrink toward the center using thinner planks. Custom patterns require more work from the installer, so expect to pay at least 20% more for this deck type.
Decking Prices by Type of Foundation
No matter which deck type you have, you need a foundation that supports the structure. There are many different deck foundations, known as footings, and they have different uses and costs. For example, if your deck is less than 6-feet wide, will attach to your home, and is not raised, you can use concrete deck blocks to support it. On the other hand, if your deck will hold a hot tub, you must have poured concrete footings, which are dug down beneath the frost line.
You can also use different footings for loose soil, for smaller decks or larger decks, and even just for your installer’s personal preference. The footings themselves are rarely more than a few feet above the ground, while most are flush with or below the ground. If your deck is raised, you will also have beams or pillars that extend down to the footing, and it will either rest on it or attach to it in some way.
The following footing costs are per footing installed, assuming normal installation conditions for each:
|Foundation Type||Average Costs (Installed)|
|Concrete Deck Blocks||$50 - $75|
|Buried Post||$100 - $300|
|Screw Piles||$150 - $250|
|Poured Concrete Footer||$200 - $400|
|Stackable Precast Forms||$250 - $350|
Deck Framing Cost
While most deck professionals quote a total cost per square foot that includes the framing, decking, and railing installations, they often charge separate costs for each one, which figure into the total cost quote. This is the case for the deck framing. There are two components to the deck framing cost - the labor and materials. Most decks are framed with either wood or metal designed for the purpose. Decking may be made of other materials like composites or vinyl, but the actual deck frame is usually made of either pressure-treated lumber or a metal-like steel or aluminum. Sometimes, you can also have your deck completely constructed of an exotic hardwood, but this significantly increases your overall costs.
|Framing Material||Average Cost per Square Foot (Installed)|
|Wood||$10 - $20|
|Metal||$21 - $35|
The average cost to frame a deck is around $8 to $10 a square foot for the labor and between $2 and $10 a square foot for a wood material. When installing a metal deck, labor costs double to $16 to $20 a square foot, with materials being between $5 and $15 a square foot.

Labor Costs to Build a Deck
The labor costs to build a deck depend on several things. The decking material, pattern, footing, and style, along with where you live all influence the labor costs of building a deck. The average range for labor is from $10 to $30 a square foot for a wooden deck and $20 to $60 a square foot to build a metal deck.
Decks are usually built by contractors who specialize in this field. They usually handle all aspects of the job, from digging the holes for the footings to the framing and final installation. Some deck contractors specialize in deck types or materials. When looking for something specific, interview several contractors, and view their portfolios. Be upfront about what type of materials you want to use because this can significantly change costs. Some contractors prefer not to work with exotic hardwoods, raising their costs when they do. Always get at least three quotes to compare.
While most decks are priced out as a total project, you can break down your total costs by the area being built or installed. Costs can range in each of these areas, depending on things like material, size, and the location you are building the deck in.
|Area||Average Labor Costs|
|Decking installation||$5 - $6/sq.ft.|
|Framing||$8 - $10/sq.ft.|
|Stairs||$15 - $20/step|
|Foundation||$25 - $300/each|
The cost to install the decking onto the frame is between $5 and $6 a square foot on average. This cost can vary depending on the material you use. A very soft wood decking like pine may cost less to install. However, a very hard, exotic wood decking like ipe may cost more per square foot to install. Likewise, if you decide to have your decking laid in an intricate pattern, this could also raise the total costs. Decking laid in straight rows is the easiest and least expensive to install.
The frame for your deck will cost between $8 and $10 a square foot in labor to build. This is the structure that supports your decking. Decks do not normally have very large frames. They will have boards that run perpendicular to the house. These boards are supported by the beams of the foundation, and attach to the house by brackets. The decking is then laid parallel to the house, or perpendicular to the frame. This gives the deck its structure, and stability in the long term.
The labor to build your deck stairs is between $15 and $20 per stair, assuming pre-cut stringers. This does include the installation of the railings as well. Decks can have varying stair needs, depending on their overall height. Platform decks may only require a single step, while two story decks will need elaborate staircases. The exact labor per step will depend mostly on the material. Very exotic hardwoods like Ipe cost the most to work with. Softwoods like pine and composites are easier to work with and cost less in labor.
Your deck foundation will cost between $25 and $300 for each post or section you have installed. Because decks can have many different types of foundation, there is a wide range of labor. Some decks will need holes dug, and concrete poured. These can cost more in labor than those that have piles mechanically driven into the ground. Those that use blocks directly on top of the ground, and which are not dug into place, cost the least in labor. Remember that it’s not the cost of the labor that’s important in this instance; the foundation will be responsible for holding up the entire deck, so choosing the right foundation for your design is crucial, regardless of labor.
Cost to Build a Small Deck
If you have a deck that is less than 6-feet wide, will attach to the house, and be installed as a platform, you will have significantly lower costs. These decks do not need expensive footers or framing, so their overall costs are much lower. Expect labor costs to be $8 to $10 a square foot, with total costs of $12 to $18 a square foot installed. Raising the deck or going larger will increase costs.
Cost to Build a Trex Deck
Trex is a brand of composite decking. It contains a high degree of recycled material and is one of the few brands of composite deck material that also makes framing, decking, and railing components. Trex is a long-lasting wood alternative that comes in several colors and finishes. It has a realistic-looking wood grain and is a popular material for both looks and longevity. Trex costs between $8 and $16 a square foot and costs the same to install as wood. The total cost range is $16 to $46 a square foot to build a Trex deck, depending on the build complexity and type and location.
New Deck Styles
Decks can be built in a wide range of styles. The ultimate style that you choose should be influenced by a few things. The first is the style of your home; your deck should be cohesive with the house’s style for the best effect. Second are your needs. How will you use the deck? What types of options will make it functional for the purposes you want to put it to? And finally, your location. If you live in rural or wooded areas or next to a lake or ocean, you may change your style to reflect your surroundings.
The contemporary deck is sleek, stylish, and minimal. These decks are often smaller than traditional decks. This means that in many cases, they may not have a foundation, but instead may be cantilevered off the side of the house. This is a good option for homes that don’t have a lot of space. These decks are also very minimal in style, so you may want to opt for wire or glass railings, rather than traditional balustrades. Many contemporary decks are also made of metal or of a combination of wood and metal for an industrial look.
The Colonial deck takes its inspiration from the Colonial home style. This is a fairly formal, traditional deck. It will be symmetrical, meaning that its shape will extend equally out to each side. You’ll probably see traditional wood decking stained a natural color. The railings, however, are almost always painted white to help them stand out. The balustrades will usually be capped as well, to give them further definition and Colonial style.
The traditional deck is made for comfort. It will have wide open spaces large enough for groupings of chairs or tables. It may be octagonal or hexagonal in shape at least at one end to help facilitate the seating. These decks usually use the same material for the decking and the railings. This gives it a very cohesive look. These decks look good on many styles of home from cottages to ranches.
If you have a mountain view, you may want a deck that will help you capture it better. These are often long, thin decks that will wrap the home. They look more similar to a verandah than a typical deck, but without the roof. They’ll have long railings and straight aways that emphasize their size and shape. They’ll also be oriented on the side or sides of the house for the best views. With these decks, it’s common to have multiple entry points from within the house.
Like the mountain deck, the coastal deck is built to capture views. These decks are often made to incorporate the colors and the materials frequently seen at the beach. This includes weathered wood or cedar that’s been painted white. To help maximize the view beyond, you may want to replace typical railings with glass or wire. These decks should make use of low maintenance materials wherever possible. The salt from the ocean can corrode metal fastenings and peel paint and stain more quickly, so composites are useful in helping to keep on going costs down.
Cost to Build a Covered Deck
A covered deck comes in many different forms. They can have roofs, pergolas, awnings, and other types of overhead structures. They have a wide cost range to build because there is a large difference in cover types, what they cost, and deck types. The average range to build a covered deck is $30 to $80 a square foot, with the labor portion coming in at around $20 to $30 a square foot. The remaining costs are for materials.
Cost to Build a Pergola Over a Deck
Adding a pergola to your deck is a great way to define the space and provide shade. Pergolas can be built with your deck using the same materials, or they can be built after, using a range of other materials, including vinyl-clad aluminum and cast iron. The average cost to build a pergola is around $3,500. This is in addition to the desk cost, which has an average cost of $12,000, making the total deck cost with a pergola $15,500 on average.
Cost to Build a Deck with a Roof
Adding a complete roof to your deck has a much higher cost than adding other cover types. In addition to the cost to build the deck, you have the roofing costs, which include $4 a board foot to frame it, followed by the cost of shingling, which can be $1 to $25 a square foot for materials, and an additional $1 to $1.50 a square foot for the shingling labor. Assuming a 320 sq.ft. deck with a roof that extends over the entire area, expect to pay $12,000 for the deck and between $1,920 and $9,760 for the roof, including all materials. This totals $13,920 to $21,760 for a wooden deck and frame.
Cost to Build Deck Stairs
If your deck is raised or has multiple levels, you need a set of stairs for access. Stairs can either be constructed onsite, or in some cases, you can purchase readymade stringers or stairs in the case of aluminum or steel decks.
Deck stairs come in many heights, with varying degrees of pitch that influence their cost. Their prices vary depending on how many treads and how wide the stairs are.
Metal stairs cost between $1,000 and $3,000 for the complete staircase, depending on the size and material. The prefabricated run of steps usually includes the railing so that the staircase easily attaches to the deck.
When building a wooden or composite staircase using pre-cut stringers - the sides of the staircase that the treads attach to - expect to pay between $25 to $35 per stair. If you decide to have custom stringers made onsite, the costs per stair can increase to $35 to $50 per stair, depending on the decking material, staircase width, and elevation.

Cost to Install Deck Railing
Deck railing is an integral part of most decks, particularly those that are raised or attached several feet or more off the ground. Railings are available in the same range of materials that decks are made from. They are available in even more materials like glass and iron, allowing the railing to be a decorative part of the deck design. Most railings are sold and installed by the linear foot. You can either have your railing built onsite from the same materials as the rest of your deck. Or, you can purchase readymade lengths of railing and have them installed. For this reason, there is a wide range of costs for railings, regardless of type. Below are the cost ranges for some of the most common types of railing material installed.
|Railing Material||Average Cost Range per Linear Foot (Installed)|
|Wood||$35 - $55|
|Metal||$50 - $80|
|Composite||$75 - $160|
|Cable||$110 - $170|
|Glass||$130 - $200|
Cost to Install Deck Skirting
If you do not want to walk or see beneath your deck, attach skirting around the perimeter. Skirting can be a lattice material that allows some light to pass through, while still obscuring the interior. It can also be a solid material made of wood, metal, or vinyl. The cost to install deck skirting depends on the skirting style, height, and material. Deck skirting costs as low as $3 a square foot installed for lattice or as much as $50 a square foot installed for materials like vinyl and composite. Stone veneer over plywood costs as much as $200 a square foot.
Deck Design Cost
Decks can be built or designed in a wide range of styles, as well as sizes and materials. Getting the design for a deck can be done in a couple of ways. You can purchase readymade deck plans, which cost around $100 to $200 on average. You can also have a deck custom-designed by your builder. In this case, expect to pay roughly $50 to $100 an hour for the designing, which can take as many as 8 to 10 hours to complete. This makes the cost of a custom design around $400 to $1,000 on average.
Deck Replacement Cost
It is very rare for an entire deck to need to be torn down and replaced due to age or wear. In most cases, the pillars and frame of the deck are still in good shape, but you may need to replace the decking, railings, stairs, or a combination of these.
However, if you want to build a new deck with different materials or a new deck in a different size, your costs to build will be similar to the cost of a new deck. You will have additional costs for demolition of your old deck, as well as the removal. The cost for this will add an additional $5 to $15 a square foot to the project, depending on the materials, how far they need to be hauled, and what disposal fees are in your area. This makes the cost to replace a deck between $19 and $55 a square foot, assuming you are replacing a deck with one of the same size.
Cost to Replace Deck Boards
One of the most common types of repairs that a deck needs is the replacement of the deck boards. Wooden boards begin to rot over time, while composites may crack or swell. When this occurs, it is very common for the frame of the deck to remain in good condition, making just the replacement of the boards a good way to keep the deck in good repair. The cost to replace only the boards is around $10 to $40 a square foot, depending on the material. In addition, there is a disposal fee of roughly $200 to $500 for getting rid of the current boards, depending on what they are made of.
Cost to Replace Deck Stairs
Frequently, it is not the entire set of stairs that need replacing, but only the treads and sometimes the risers. The stringers, or the sides of the stairs, rarely require replacement. The cost to replace the entire set of stairs, stringers and all, is around $45 to $50 a step. The cost to replace just the treads and risers is around $20 to $40 a step.
Keep in mind that these costs are for wood and composite steps only. Metal stairs cost $1,000 to $2,000 for the new stairs, depending on the height and material. Also, add in a disposal fee for the old stairs of around $200 on average.
Your footings are your deck’s foundation. They are what give it support and keep it upright and stable. If your soil has shifted or you are moving or reconfiguring your deck, you need to replace the footings, which means removing the old footings and installing new ones. This can be an involved process, depending on the footing types involved. The average cost to replace footings is between $300 and $400 per footing for most concrete, concrete form, buried post, and screw piles. The cost to replace block foots is usually much lower, around $100 per footing.
Cost to Build a Deck Yourself
With labor costs to build a deck ranging from $10 to $30 a square foot for a wooden deck, homeowners experienced in carpentry and building can save money by building their decks themselves. When doing this as a DIY project, keep in mind that deck builders have the machinery, tools, and trucks for hauling materials that allow them to work more efficiently. If you do not have access to these items, add these costs to your total, including the delivery of your materials, which can cost up to $200 on average. You may also need relevant tools, which have additional costs. Materials alone cost between $2 and $30 a square foot, just for the lumber and decking. For additional materials, such as concrete, nails, brackets, and decking fasteners, add another $2 to $5 a square foot to your project, making your total range between $4 and $35 a square foot. In addition, add in delivery and equipment rental fees for building the deck yourself.
Cost to Stain a Deck
If you choose a pressure-treated deck, you need to have it stained as part of the building process to protect it from wear. If you choose a redwood, cedar, or other wood deck, you can leave it bare, but you may still want to stain it to improve its appearance, coordinate it with the rest of your home’s exterior, or help extend its lifespan. Some materials like cedar and redwood require a primer to prevent bleeding through the stain or paint. The average cost to stain a deck is around $750 and includes sealing in the cost.
Deck vs Patio
If you want to use your deck as an outdoor living area, another option is to also install a patio. Both decks and patios have various styles and appearances. Decks can either be platforms that are installed just above the ground or be raised up several feet. Patios are installed directly on the ground, with no elevation, so they can be a better option for those with limited mobility who want to access the yard from the patio. Decks, however, can be multiple levels, which give you options for entering from many areas of the house or yard.
In general, a patio is a much less expensive option than a deck. Patios cost around $2,000 to $4,000 on average, while a deck averages around $12,000 completely installed.
Porch vs Deck
Another popular outdoor living area that can enhance your home’s exterior is the front porch. While the deck is an addition built onto the back of most homes, the porch is an addition built onto the front, becoming an extension of the front entrance. Porches are integral to your home’s curb appeal, so they need to match things like the color and detail, while decks can have more latitude in their appearance. Porches also have a roof, which has both a finished ceiling and exterior that matches the rest of the home’s roof. For that reason, porches tend to be much more expensive than decks, averaging between $16,000 and $30,400 on average.

Enhancement and Improvement Costs
Removal of the Old Deck
The debris removal from an old deck averages $15-$30 per hour. The cost to dispose of the old deck averages $100-$500, depending on the volume of debris removed.
Deck lighting adds ambiance to the area and also lets you enjoy the space after the sun sets. You can have deck lighting installed for $35-$200 per deck light. An electrician charges $40-$100 per hour on average for electrical wiring.
Many people choose to place lattice around the base of their deck. The price of wood lattice averages $30 per piece. Vinyl lattice averages $15 per piece. A lattice skirt not only completes a deck’s appearance but also prevents animals and other things from crawling beneath the deck. It acts as a barrier around the deck’s base. You can have it professionally installed by your deck contractor at the time they construct the deck.
An outdoor kitchen allows you the freedom to cook and entertain on the deck. You can have a basic or lavish outdoor kitchen placed on your deck. The cost of an outdoor kitchen ranges from $2,700-$10,000.
With a wood or gas fire pit, you can make s’mores and also stay warm during a brisk day. A wood or gas fire pit averages $500-$3,800.
A deck cover provides shade and also protects the surface of the deck. They can be a simple cloth covering or elaborate roofs, depending on your needs, style, and budget. Cloth covers start at around $1,200, while full roofs can cost as much as $8,000 to $10,000, depending on the material.
If your deck is large enough and is reinforced to hold the weight, you can add a hot tub. Hot tubs come in a range of different sizes and materials. Depending on the fuel type and location, you may also need to install a gas line or electrical outlet. Hot tub installations cost around $6,900 on average.
Outdoor Deck Shower
If you have the privacy in your yard and either a pool or another area to swim nearby, you may want to add an outdoor deck shower. This allows you to rinse off before going inside. The average cost to add an outdoor shower is around $1,000 for a simple shower or up to $8,000 for a full enclosure.
- How much does it cost to build a 20x20 deck?
A 20’ x 20’ is 400 sq.ft. Depending on the style and materials, this has a cost range of $14 to $44 square feet or $5,600 to $17,600.
- How much does it cost to have a deck built?
A deck costs $14 to $44 per sq.ft. fully installed, depending on the style and materials.
- Do I need a permit to build a deck?
Most areas require a permit to make any addition to your home. Decks fit the definition of an addition in most areas. Your contractor or builder can assist with getting the correct permits. You can also check with your local town or city hall for more information.
- What size deck should I build?
A 16’ x 20’ deck is a popular size for a standard 1,600 sq.ft. house. However, larger houses might benefit from a bigger deck, and a smaller home may require a smaller structure to look balanced.
- How much does it cost to build a 10x16 deck?
A 10’ x 16’ deck is 160 sq.ft. The cost of construction averages between $14 and $44 a square foot, depending on the deck materials and style. For a 160 sq.ft. deck, expect costs to fall between $2,240 and $7,040.
- Does adding a deck add value?
In most areas, yes a deck can add a lot of value to your home. Decks enhance your enjoyment of the yard and can be used as an outdoor living area. A wooden deck addition has an ROI of 72%, while a composite deck addition has an ROI of nearly 67%.
- How long does a deck last?
Decks have varying lengths of longevity due to the different materials they can be made of. In addition, a deck that is well cared for, stained, and sealed regularly will likely outlast a deck that is not being cared for. Expect wooden decks to last at least 10 to 15 years and composites 20 years. Many decks can last much longer than these estimates with proper care.
Cost to build a deck varies greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.

|10x10||100||$1,500 – $3,500|
|10x12||120||$1,800 – $4,200|
|12x12||144||$2,160 – $5,040|
|12x20||240||$3,600 – $8,400|
|14x20||280||$4,200 – $9,800|
|16x16||256||$3,840 – $8,960|
|20x20||400||$6,000 – $14,000|
Labor Cost To Build a Deck
The labor cost to build is deck makes up the bulk of the price at between $8 and $22 per square foot depending on the size, materials used, level built on, conditions of the area, and any extra options like built-in seating or stairs.
Cost Of Lumber To Build A Deck
For the most common woods used in decking, you can expect lumber costs to range from $6 to $8 per square foot. For premium hardwoods and composite materials, you can expect to pay anywhere from $20 to $35 per square foot.
Cost To Build A Deck Yourself
Building a 10x10 foot ground-level deck yourself would cost about $700 for the materials versus paying a professional around $2,200 total. You could use pressure-treated lumber to build a 16x16 foot deck for $1,500 or hire a contractor to do the labor for you for about $6,400.
Using premium materials for your DIY deck such as Trex, Ipe, or Tigerwood to build a 16x16 foot deck yourself would run about $5,100. To hire a deck builder instead would cost a total of about $13,620 for both labor and materials.

Material Costs To Build A Deck
Material costs to build a deck range from $6 to $8 per square foot on average. The three most popular materials for the construction of outdoor decks in the US are pressure-treated wood, hardwood, and recycled composite.
|Deck Material||Cost Per Square Foot|
|Bamboo||$3 – $4|
|Cedar||$4 – $8|
|Pressure-Treated Wood||$5 – $8|
|Redwood||$7 – $8|
|Tigerwood||$6 – $15|
|Ipe||$10 – $15|
|Composite Decking||$10 – $15|
|Trex Decking||$8 – $20|
The cost of materials provided is an average from across the country, and depending on where you live, you may experience slightly more or slightly less per square foot for your project.
Pressure Treated Deck Cost
On average, a pressure treated wood deck costs $6 per square foot for materials, or between $12 and $18 per square foot installed. Pressure-treated wood (PT) is used on almost 75% of all decks in the US today. Chemically treated under pressure, it is fabricated to make the wood more resistant to mold, insects, and rot.
- Pressure-treated wood is generally made from low-grade fir or pine that tends to warp and crack over the long haul, and that creates the ongoing need for a rigid maintenance schedule.
- When pressure-treated wood meets water, any metal used in the construction of the deck like aluminum flashing, galvanized nails and screws, fasteners, joists, and deck hangers will begin to corrode. If left without being repaired will cause dangerous structural instability in your deck.
- If you elect to have pressure-treated wood used in your deck, you are signing up for a regular maintenance schedule that includes sanding, sealing, and staining.
Wood Deck Costs
The materials cost to build a deck with natural wood is between $3 and $15 per square foot with most homeowners spending $6 to $8 per square foot on average. Wood decks are beautiful and a top-choice for homeowners, however, they require more maintenance such as staining and sealing regularly. Here are the most common woods used for decking:
- Cedar – At $4 to $8 per square foot, cedar is naturally resistant to weathering, insects, and rot. It requires yearly maintenance of sanding, sealing, and staining.
- Bamboo – Bamboo is the cheapest material used in decking at an average cost of $3 per square foot. Like cedar, it requires annual maintenance to keep it healthy.
- Redwood – Redwood decking costs $7 per square foot and is the most common wood used in deck building. Without regular maintenance, it can develop mold and get damaged by the sun.
- Ipe – Ipe is a Brazilian hardwood that costs between $10 and $15 per square foot on average. It typically lasts over 40 years and resistant to mold. However, it's by far the most expensive wood to use.
- Tigerwood – Tigerwood is one of the most expensive hardwoods used in decking at an average cost of $6 – $15 per square foot. Like Ipe, it lasts longer than 25 years, and special tools are needed to drill holes into for installation.
Redwood Deck Cost
The most common type of natural wood used in deck building is the redwood from California. A redwood deck costs between $15 and $21 per square foot installed, and around $7 per square foot for just the materials. Redwood is just a little more per square foot than pressure-treated wood.
- You avoid all the downside of infused copper and the corrosion.
- It is just under half the cost of recycled composite lumber.
- Redwood is excellent for either painting or staining.
- It is naturally resistant to pests and fire.
- It does not warp easily and is long lasting.
- If your redwood deck isn’t maintained regularly with staining and sealing, it can develop mold and get damaged by the sun.
Cedar Decking Cost
Cedar decking costs between $4 and $8 per square foot for the materials depending on the grade selected. Cedar is a natural softwood that's offered as treated or untreated. Most of the time cedar planks are left untreated because of its natural resistance to weathering and rot.
- Cedar is one of the most cost-effective materials used in decking.
- Naturally resistant to weathering, rot, and wood-destroying insects such as termites.
- Cedar is easy to stain, seal, and will not warp from aging.
- Cedar boards are not as strong as other hardwoods which produce scratches and dents easily.
- Requires regularly yearly maintenance of sanding, staining, and sealing.
Ipe Decking Cost
Ipe, also know as Ironwood, is a Brazilian hardwood that costs between $10 and $15 per square foot on average.
- Ipe has a life expectancy of over 40 years.
- Ipe is three times harder than oak and won't scratch or dent like other kinds of wood.
- Ipe requires little maintenance, other than applying oil yearly.
- It requires special tools to drill holes into the wood and install
- Ipe can cost as much as three times as much as standard pressure-treated wood.
Composite Decking Cost
The average cost of composite decking ranges from $23 to $38 per square foot installed, and between $10 and $15 per square foot for just the materials. Most homeowners spend between $5,821 and $10,826 to install a 12’ x 24’ composite deck with railings.
Recycled composite is fabricated to look like real wood, and it's growing in popularity deck building material. It’s made from recycled plastic with two of the most common options including polyethylene, polypropylene, and polyvinyl chloride or PVC.
- It is generally one of the most expensive options.
- Will require very little maintenance
- Never splinters or rots
- Has no chemicals in it that will corrode metal fasteners
- Available in a range of colors
- Does not need to be stained or sealed
- Some composites are available as “hollow core” planks which allow for either electrical or audio cable to be run through the core.
- If the product gets dinged, it is not as easy to restore to its former glory as wood is because it cannot be sanded.
- In very high temperatures, it may be a warmer surface underfoot when compared to wood.
Trex Decking Cost
A typical 24’ x 12’ deck built with Trex decking costs between $4,244 and $10,826 for materials and installation. Trex decking materials cost between $8 to $20 per square foot on average.
- Trex boards are naturally resistant to fading and staining, as well as mildew, mold, and even termites. Also, Trex boards won’t warp, rot, crack, split, or splinter.
- Trex offers a 25-year warranty on the product and its ability to remain stain and fade-free.
- There is no need to treat your deck for insects, stain, seal, or to waterproof it.
- Trex boards cannot be refinished or recolored.
- Like most composite solutions for decks, materials are more expensive.

|Outdoor Kitchen w/ Sink||$1500 and up|
|Roofing / Pergola Framing||$0.70 – $1.30/sqft|
|Cover||$1,000 manual, $1,700 motorized|
Cost To Build Deck Stairs
Adding stairs to your deck costs $150 more on average depending on the number of steps required. A rough rule of thumb to calculate your final price is $40 per step. The addition of some steps will make a nice transition from the yard onto the deck. Depending on the size of the yard, one set may be sufficient, although you may choose to add the steps on either side of the deck.
|Number of Steps||Average Cost|
|2 Steps||$110 – $165|
|3 Steps||$100 – $140|
|4 Steps||$140 – $190|
The variance in cost depends on whether you want an open vertical space between each step or if you’d instead close it up with a matching riser. Also, concrete footing for each set of steps for support (excluding excavation) is $50.
Cost To Install Deck Railing
Depending on the material used in building your deck, the average cost to install deck railing is $20 per linear foot. Normally a railing will not be on all four sides of the deck because one of the sides of the deck will be along the house. For a 42”-high handrail, one 2’ x 4’ horizontal top rail, and one 2’ x 6’ placed on the edge directly below the top rail, prices with balusters are:
|Deck Railing Material||Average Cost|
|Pine, pressure treated||$15 per linear foot|
|Redwood, select heart||$19 per linear foot|
|Recycled composite lumber||$36 per linear foot|
Deck Fireplace & Fire Pit Cost
To add a fireplace or a fire pit to your deck, you can expect to spend between $200 and $500 for a store-bought heater, or between $2,700 and $6,500 for a custom built-in solution. There are many options to choose from, including the following:
|Heating Solution||Average Cost|
|Tall Butane Heaters||$100 – $500|
|Custom Fire Pit||$2,700 – $6,000|
|Custom Outdoor Fireplace||$6,500+|
- Fireplace options start with a small, wood-fired, self-enclosed metal structure with metal-mesh side panels that allow the heat to escape on all four sides.
- At around $1,000 for a firebox–which is like an indoor fireplace and only allows the heat out through the front.
- From between $1,400 and $6,500 for products typically mounted in a tall, vertical structure similar to an interior fireplace complete with its own chimney. These products are also available as wood-burning or gas-fired fireplaces.
Patio Enclosures Cost
The average cost of a patio enclosure is $900 for a pre-built kit or between $8,112 and $18,748 to enclose a deck or create a custom sunroom. At around $70 per square foot, you can either partially enclose or fully enclose your deck.
Screened In Deck Cost
The average cost to build a screened in porch on an existing deck is about $4.50 per square foot. This would bring you to a total of $600 for a small porch with basic materials up to $3,510 for a large wrap-around porch with high-end materials.
As a budget alternative, you can also choose to install a privacy netting screen. This is available to the consumer in 15’ x 3’ lengths and is almost 3 feet high. Generally, each panel will run around $20, will still need deck posts to tie to at each end, and will typically be attached to a top rail with screws and washers through grommets.
Deck Flooring Costs
Once your deck is built, you can add flooring at an average cost of between $2.50 and $4.00 per square foot installed, and even pay $1.00/SF extra to add diagonal pattern decking. Prices below are based on a deck with 200 square feet of area.
|Flooring Type||Average Cost|
|Pine, 5/4” x 6” thick, pressure-treated deck flooring||$2.50/sqft|
|Redwood, 2” x 8” thick, select heart deck flooring||$4/sqft|
|Recycled, 5/4” x 6” thick, composite lumber decking||$8/sqft|
|Recycled composite lumber decking 2” x 8” thick||$14/sqft|
|Add for stain with sealer finish||$0.40/sqft|
Additional cost for diagonal pattern decking
|Deck Flooring Type||Average Cost|
|Pine decking, pressure treated||$0.40/sqft|
|Recycled composite lumber decking 5/4” x 6” thick||$1.00/sqft|
|Recycled composite lumber decking 2” x 8” thick||$1.90/sqft|
Built-In Deck Seating
Depending on your desire to go upscale with some unique custom designed seating designed and built by your installer, or to add your own bench style options, there will be something for every budget.
On the lower end of the spectrum, you can expect to pay:
- $350 to $1,100 to add premanufactured, waterproof bench-style seating
- $2,000 to $5,000 or more to have an L-shaped bench built and installed
Deck Planter Boxes
The average cost to add deck planter boxes is between $80 and $150 each depending on the type of materials. Wide, narrow, rectangular planter boxes are available in wood, metal, and a range of plastic composites. Taller, deeper planter boxes which hold less are also available for roughly 15% less than the rectangular options.
- From $80 for wood
- From $120 for plastic
- From $150 for metal
Cost To Add Hot Tub To Deck
The average cost to install a hot tub to a deck is $4,000 and $15,000 depending on the size, features, and model. Depending on the number of people you want to accommodate in the hot tub; the number of jets; how long you want the product to last; the type of inner shell; and features like drink holders, colored LED lighting, etc., you will see a range of prices:
|Hot Tub Type||Average Cost|
|Entry Level||$2,000 – $4,000|
|Mid Level||$5,000 – $8,000|
|High End||$9,000 – $12,000|
|Luxury||$13,000 – $15,000|
For the hot tub installation, you can simply set the hot tub right on top of the deck, or, if you have a slightly raised portion of the deck, it can be set down into a cutout. If the hot tub is going to be recessed, then some form of entry will need to be created to provide access for any maintenance that the hot tub pumps or electrical setup might need.
Alternatively, building an outdoor sauna costs$5,500 to $34,000.
Outdoor Deck Shower Cost
Depending on the type of shower you want to install–allowing you and your family to rinse off after using the hot tub or pool–and the distance from the nearest water line, your costs will be:
- $800–$1,000 for a nice wall-mounted shower with a small 3’ by 3’ wood floor
- $4,000 or more if you want to install one with a privacy enclosure–like an interior shower
Outdoor Kitchen On Deck Costs
If you just want a sink cabinet and counter area that you place your grill next to, you are likely to spend:
- $600–$900 for an entry-level, medium-sized, mid-priced sink
- $1,500 and up for a larger sink with an exquisite faucet
- $7,000–$17,000 if you want to go all out and create a complete outdoor kitchen with a small fridge, counter space, and cabinets
Cost To Build Pergola or Roof Over Deck
The average price to build a roof over your deck, or add pergola framing is between $0.70 and $1.30/sqft. Include $40 to $50 for supporting posts and concrete, and an additional $2.60 per square foot for flat asphalt roof covering. Another option is a manual deck cover which costs $500 to $1,500 or $1,700 and up for a motorized cover.
Cost To Install Deck Skirting
The average cost to install deck skirting is between $25 and $30 per square foot. Adding a skirt can finish out the look of the deck from your walking surface down to the ground and protect that space from large rodents.
- Trellis - $25/sqft
- Privacy fence style - $30/sqft
The finished product will look like a privacy fence–with little to no gap between the boards–or it will be more like a trellis with the wood in either a diamond or square configuration. A complete absence of gaps will rule out the space becoming home to rodents or snakes, while the trellis option is more suited to being a visual addition.

Cost To Repair, Rebuild Or Replace Your Deck
With a natural wood deck, annual maintenance, repairs, and rebuilding is part of the game. With lots of upkeep, your wood decking can last 25 to 40 years before you need to replace. However, not maintaining your deck drastically reduces its lifetime down to 10 to 15 years.
Deck Repair Costs
Plan ahead for maintenance and deck repair costs, to include:
|Maintenance & Repair||Average Cost|
|Damaged deck boards||$1,280|
|Loose deck stairs||$150 – $300|
|Missing deck nails||$5 – $10|
|Mold, mildew, and rot||$200 – $500|
|Damaged deck railing||$400 – $500|
|Termite and pest treatment||$100 – $300|
|Stain and seal||$3.50/square foot|
Cost To Stain A Deck
The average cost to sand, stain, and seal a deck is $1 to $3 per square foot. If you only have a small area that needs to be repaired, you can buy the sealant and stain and complete that portion of the project in your own time.
- Stain – Available as an opaque or semi-opaque stain in acrylic latex, oil, or latex. Covers 400 square feet of wood surface and costs $30–$45 per gallon.
- Wood finish – Available as a transparent or waterproofing finish. Covers 400 square feet of wood surface and costs $16–$80 per gallon.
Cost To Seal A Deck
You should strive to reseal your deck annually. An average wood sealer costs about $20 per gallon and can easily be applied yourself.
- Wood water clear sealer – covers 225–325 square feet of sanded wood and 125 square feet for the initial coat on rough-sawn wood costs $16–$18 per gallon.
- Wood preservative – covers 100 to 300 square feet and costs $24–$29 per gallon.
Deck Removal Cost
On average, deck removal costs between $5 and $10 per square foot depending on the size and condition of the old deck. If you have a multi-level, built-in seating, or railing, removal prices will increase. An average 12x12 deck that consists of 144 square feet costs between $720 and $1,440 to remove.

Estimating The Cost Of Building Your Deck
If you’re tired of walking out your back door and having nothing decent outside to relax on, never mind host a BBQ or enjoy a stint in the hot tub, a deck can meet your outdoor living space needs.
Build one level, or include some raised portions; stretch it the full width of the back of the house or contain it to the area by the back door. No matter how large you go, make sure it meets your home improvement needs.
The main thing you need to choose before you start is the size of the deck. Standard advice is to make a deck a minimum 12’ by 12’ to make it a useable space for an average size family.
Many home builders will include an upgrade of a small 10’ x 10’ deck, but many people either regret going with one so little, or they upgrade before the home and deck are built.
In general, if you want a large deck, consider keeping it around the same size as the largest room in your house.
You may elect to have one or two raised portions on the deck and possibly add a hot tub, which will increase the deck’s visual appeal, cost, and the overall value of your property. Another option is to continue the deck to a second floor.
To get an idea of the size that fits your plan of use, look up the average sizes of furniture for the number of people you want to entertain. If you plan on having a dining section on the deck, then allow around 3’ around that table. Add square footage for any firepits, butane heaters, grills, or other accessories.
Ground Level Vs. Second Story Deck
In general, a deck will be built no more than two inches below the bottom of the door used to access the deck.
Types of decks:
- Low elevation deck - for houses built at ground level
- Mid-elevation deck – for raised houses
- High-elevation deck – for split-level homes
A high-elevation deck with a space under it less than eight feet tall could be used for storage for lawnmowers and yard equipment. If the space is at least eight feet high, then you could create an additional living area with a deck floor and ceiling leaving a balcony for the top, which will add an additional cost per square foot.
HOA & Neighborhood Restrictions
Check with your local governing authorities and homeowner’s association, to see what regulations and building codes you need to adhere to, and to see if you need a building permit. Some restrictions are created to regulate the minimum distance between your deck and a well, a septic tank or its drain field, and even a neighbor’s house.
Because the deck will increase the value of the home, it will also raise your property taxes. That amount will depend on the total cost of the project and your local property tax rate. Have a tax assessor come and inspect the deck once it’s built. It is not uncommon to be notified of any changes in your tax estimate while they are at your property.
Policies will already allow for coverage of an additional deck when it is attached to your home, just like it would cover damage to a garage or any other attached structure within the covered hazards portion of the policy. While there are some differences between states, according to the Insurance Information Institute, most homeowner insurance policies cover standard hazards from weather damage, fire, and other damage.

Deck Styles & Types
- Dining Area Size – If your plans are more centered around eating on your deck, build your deck an average size of 12’ x 14’ to comfortably seat 6–8 people around a 48” round table and still have room around the table for foot traffic.
- Living Room Size – To replicate an average living room, build a deck of 16’ x 18’ or 12’ x 24’. With a deck of this size, you can furnish it with ample lounge chairs, a coffee table, and an outdoor sofa. Also, you could add an outdoor gas fireplace for the colder months. Alternatively, you could mix it up and have a love seat and table and chairs for four people.
- Location relative to your house – The vast majority of decks will be constructed entirely against the house or via a connected patio.
- Intended deck use – Access to the deck from the back door is convenient and gives easy access to your indoor kitchen, but an additional extension to the deck could wrap around the side of the house–granting access via a door to the master bedroom and adding a separate quiet spot to relax in during the evening.
- Seclusion – While the back of the house is the most private location on your property to build a deck, some homes are built on alternating elevations that can put neighbors’ houses somewhat higher than yours. It should be possible to increase the degree of private space with the installation of a lattice trellis on one or more sides of your deck, adding an extra layer of privacy.
- Surrounding scenery – Consider adding an extension or elevated area if it will give you a chance to enjoy the view of nearby hills or woods.
- Direct sun exposure – If you live in a region that typically allows for more cold days than hot, then the ideal location for the deck is a spot where the sunlight falls for the majority of the day. Alternatively, if you live in a hotter region like Arizona or Texas, the typical preference would be a location with as much shade as possible during the day.
- Existing trees – Sometimes there could be one or more trees in the desired deck installation site. You may have to cut them down if that is permitted by local governing authorities. Depending on the maturity of the tree(s), though, it may be possible to incorporate the tree into the deck, resulting in a more organic relaxation zone.
- Wind – The most ideal location for your deck is one that has the least amount of wind regularly.
- Landscaping – If you were also planning to landscape the yard, schedule it at the same time as the deck design to make both the deck and the yard a fluid thing of beauty.

Cost To Build A Deck
If you’re building a new deck, it’s likely that your most pressing question is “how much does it cost to build a deck?” While there are no easy answers to the question, there are still a few variables you can solve. Although the costs for labor and installation can vary from contractor to contractor, you can get a rough estimate for the amount of materials you’ll need to build your new deck.
How much does it cost to build a deck?
Costs for materials for a deck range according to a number of factors, including:
- Square footage of your deck plan
- Height, width, and depth of your planned structure
- How elaborate your design is (for example, is there enough room in the budget for a shed roof?)
- The type of materials you plan to use and how much they cost within your particular region of the country
For instance, let’s look at average costs for a 10’ x 10’ deck:
- If using pressure-treated pine, you may pay between $1,061 to $2,350 for materials
- Materials for that same 10’ x 10’ deck can cost between $3,003 and $6,297 if using exotic hardwood
- Using composite to build a 10’ x 10’ deck can cost between $1,983 and $4,293
If you were to go a bit bigger and build a 20’ x 18’ deck:
- If that deck had a height of 8’2” and ran a total of 339 square feet, pressure-treated pine would be your least-expensive option for materials at $3,062. If you used exotic hardwood, materials would cost nearly $8,000. If you opted for composite, cost of materials would be $5,318.
- Now, if you built a deck with a height of only 3’9”, costs would be less expensive with economical pressure treated pine running $2,775. Exotic hardwood materials would cost $7,245 and composite may cost $4,603.
Please keep in mind that these costs can vary according to a number of the factors we’ve talked about before. However, you can use the calculator below to get the best possible estimate for materials for your new deck.

Considering this, how much does it cost to build a 20x20 deck?
The average homeowner spends $2,200 to build a 10x10 foot deck, $6,160 to build a 14x20 deck, and $8,800 to build a 20x20 deck. The cost to build a deck with pressure-treated wood, hardwood, or composite is about $25 per square foot, for both materials and installation.
Secondly, how much does it cost to build a 10x16 deck? Doing it yourself, you can build an 8x10-foot ground-level deck from treated lumber for about $500 in materials. Having a contractor build it for you raises the price to $1,500. You could build a treated-lumber raised deck, say 10x16 feet, for about $1,500 in materials.
Simply so, how much does it cost to build a 12x12 wood deck?
The cost of a professionally built pressured-treated wood deck starts at about $15 per square foot, including materials. The cost for an elaborately built deck using costly hardwoods or composite materials can run about $35 per square foot.
How much does a 300 sq ft deck cost?
Homeowners across the US, report spending $20-40 per square foot on a new deck, including labor and materials. This is about $6,000-12,000 for a 300 sq. ft. deck.
