HomeAdvisor members report the average new deck installation costs $7,239 with a typical range of $4,072 to $10,421. Including both materials and labor, expect to pay $16,000 for a 16-foot by 20-foot deck with footings, posts, railings with balusters and a built-in bench. Wood will average $13,000 total, while composite materials increase the material price to $19,000. Labor and materials each make up roughly 50% of the budget or $15 to $30 per square foot.

Second story installs and unique designs add 30% to 60% or about $8 to $20 per square foot to the base price. Your total budget depends on various factors including size, design, location, building materials, and extras to enhance functionality. You’ll also want to plan for any large additions like an outdoor kitchen, pool or hot tub.

Deck Material Prices

Materials make up anywhere from $20 to $45 per square foot. This includes all planking, beams, bolts and railings. For simple decking planks used for the walking surface, you might spend between $2 and $30 per square foot. We’ll talk more about pricing for decking in the next section.

Less expensive materials require more maintenance, like regular cleaning and resealing to avoid rotting and color changes. When choosing materials for your project, your options fall into three main categories: plastics, wood and composites.

Plastics & Composite Decks

  • Composite decking materials cost $30 to $40 per square foot. Includes moorings, railings, framework, hardware and other components.
  • Decking: $12 to $22 per square foot.
  • 320-square-foot structure: $9,600 to $12,800, not including labor.

Pressure-Treated Wood Deck Cost Per Square Foot

  • Pressure-treated wood materials: $15 to $20 per square foot.
  • Decking: $2 to $5 per square foot.
  • 320-square-foot structure: $4,800 to $6,500 not including labor.

This is an attractive material for those on a budget.

Elevated Concrete Deck Cost

Elevated concrete decks range anywhere from $30 to $75 per square foot depending heavily on your location, the dimensions of the slab and what finishing materials you choose. You or your contractor should have the structure designed by a licensed engineer. Hiring a residential structural engineer costs $300 to $700.

Finishing options include:

  • Paint
  • Stamped concrete.
  • Tile

Steel Deck Framing Cost vs. Wood

Steel framing runs 50% to 100% more than wood. The price continues to drop as it becomes more popular. Many installers use wood posts clad in steel with metal joists and fasteners. These systems are perfectly straight and never warp, rot or twist. Most composite decks, like Trex, use steel frames.

Decking Board Costs

Decking runs anywhere from $2 to $30 per square foot. “Decking” refers only to the planks that make up the walking surface of the porch. This cost does not include hardware, framing, concrete, posts or other supporting construction.

For a unique, elegant finish, try using concrete, steel or pressure-treated wood for your framing and finishing with a warm wood, such as redwood, mahogany, Ipe or bamboo. Each have their own costs, pros and cons.

Redwood Decking Cost

Depending on the grade, a redwood decking runs $5 to $30 per square foot. The average 320-square-foot redwood deck runs $6,400 to $12,800.

Redwood Deck Pros & Cons
ProsCons
Naturally pest resistantSourced from old growth forests (not renewable)
Fades over time to a beautiful silver greyProne to molds
Lasts for decades with proper careCan get UV damaged if not stained
Not prone to warpingExpensive

Mahogany Decking Price

Mahogany, an American hardwood, costs $8 to $11 per square foot for planks. Total material prices will vary because it's not used in the posts or framing. You might find this on concrete, steel, aluminum or pressure-treated framing.

Advantages & Disadvantages of Mahogany Decks
ProsCons
Low maintenance compared to pressure treatedModerately expensive
Rich, natural appearanceNot always responsibly farmed
Takes stains wellHigher maintenance than composites/metals

Ipe

The $10 to $20 per square foot. Tight regulations and industry oversight can make the tropical woods harder to come by, but their durability is enough for some people to justify the price.

Ipe Hardwood Decks
ProsCons
Very strong, sometimes called “ironwood”Difficult to work with. Expect to pay more for labor.
Lasts 25+ yearsDoesn’t accept stain or preservatives
Resists mold, fire and physical damageExpensive upfront investment
Sustainably grown

Tigerwood Backyard Deck Cost

Tigerwood, another Brazilian and African hardwood, runs $7 to $15 per square foot. Tigerwood has a distinctive striped pattern from which it gets its name. It's slightly cheaper than Ipe and comes with many of the same durability qualities but with a different look.

Tigerwood Decking
ProsCons
Weather resistantRequires regular maintenance
Less expensive than IpeStainless steel fasteners needed
Has a striped appearanceHard to install, expect to pay more for labor
Lasts 25+ yearsNot always sustainably farmed

Bamboo Decking Costs

Bamboo runs $3 to $10 per square foot. It's actually a grass, not a wood. Bamboo is a fairly new material. When purchasing, be sure it comes from sustainable farms. Unscrupulous dealers may harvest from wild regions and damage natural habitats.

Bamboo Deck Pros & Cons
ProsCons
Cheap and durableNot good in northern climates
Environmentally friendly renewable resourceCan be difficult to install
Mold and rot resistantRequires annual sealing
Consistent grain without knots
Compare Estimates For Different Deck Boards

Cedar & Other Wood

Cedar planks cost $3 to $7 per square foot. This naturally insect and UV resistant wood is only slightly more expensive than pressure-treated woods and comes without any of the chemical treatments. It's an excellent environmentally-friendly softwood grown in North America and harvested sustainably.

Pros & Cons of Cedar
ProsCons
Rot & insect resistantProne to warping
Moisture resistantInconsistent color and patterns
InexpensiveHigh maintenance for longevity
Sustainable materialDamages easily
Other woods, like Douglas fir and knotty pine, are inexpensive alternatives but require regular maintenance since they don't resist rot or insects like cedar does.

Aluminum & Metal Decking Costs

Aluminum runs $15 to $20 per square foot. Many of these systems are gapless, meaning they make a seamless waterproof roof for anything underneath. Because they are both waterproof and lightweight, they make great outdoor spaces that double as roofs above carports, patios and outdoor kitchens.

Aluminum Deck Advantages & Disadvantages
ProsCons
LightweightExpensive
Long lasting and won’t rustHard to paint or change colors
Don’t warp or twist over time like woodDents and scratches easily

Fiberglass & Composite Decking

Composite decking is $12 to $22 per square foot. It's roughly 40% more expensive than wood.

Vinyl, Fiberglass or PVC Deck Pros & Cons
ProsCons
Never warps, shrinks or bendsExpensive option
Maintenance freeCan fade over time

Cost to Build a Deck Calculator

When calculating the cost of building a deck, you have to figure in more than just the wood. Be sure to factor in size, other construction and protection elements, taxes and insurance and all the little extras that make it not only usable but enjoyable!

Deck Cost Calculator
FactorAverage Cost for 320 Square Feet
Materials$8,500
Labor$7,000
Permits$500
Total$16,000
  • Budget for property tax increases which vary by state and municipality.
  • You’ll also want to include any increases to your insurance premiums from increased home value.

Deck Size Cost Estimator

Most decks fall it the $30 to $60 per square foot range. However, other factors can impact this figure such as:

  • Regional pricing differences.
  • Complex designs.
  • Second story installs.
  • Material type chosen.

If you want a large or elaborate install, you will spend quite a bit more than for a small platform. It comes down to functionality. The following chart assumes a first floor install with railings, balusters, stairs and made from mid-grade materials. Most fall in the 300 to 400 square foot range.

Average Deck Costs by Size
Dimensions (Square Footage)Total Square FeetAverage Price Range
8x8 (64)64$2,560-$3,840
8x10 (80)80$3,200-$4,800

16x20 (320)320$12,800-$19,200
20x20 (400)

Labor Cost of Building a Deck Per Square Foot

Most pros charge around $35 per square foot. Expect to pay more for Ipe, Tigerwood and other extremely tough-to-work-with woods.

Taxes & Insurance

The average wood deck increases a home’s value by about $10,000 or about 50% to 75% of your installation investment. Expect your property taxes to go up as well. You may also increase your insurance premiums.

  • Check with your local assessor’s office for tax data and information.
  • Call your insurance agent during the planning phase for premium increases.
  • Check with the contractor for a Certificate of Occupancy. This certifies the deck load capacity for a specific number of people.
  • Make sure the contractor carries insurance.

Deck Designs & Cost

This guide covers basic rectangular and L-shaped designs. For complex, multi-level or wrap around decks, you can expect to add anywhere from 50% to 100% to your budget. Not only do complex designs require more time to install, they also present a higher amount of waste materials, planning and preparation.

Average Cost to Build a Deck with a Roof on It

It’ll run anywhere from $5,000 to $35,000 to build one with a roof on it. If you find that it isn't comfortable enough year-round, go the extra mile and build a roof, enclosure or sunroom.

Cost of Deck Installation with Stairs

Adding stairs runs $15 to $25 per square foot in addition to your base price. They’re time and labor intensive to install.

Floating Deck Cost

Floating decks run $20 to $60 per square foot. The only difference between the floating and standard type is attachment. Floating styles aren’t attached to the home and require a few additional support posts underneath the structure.

Second Story Deck Prices vs. Ground Level Decks

Adding one to a second story ranges from $40 to $50 total per square foot for additional posts and stairs. Accessibility issues can push that price even further up. For example, trying to install one over a garden or pool requires erecting additional scaffolding.

Ground level decks range from $10 to $20 per square foot or about half the price of a standard style. This is because they have no stairs and often no railings. Consider these a wooden patio.

Cost to Build a Roof Deck

You’ll spend at least $25,000 for a basic rooftop deck. With luxury upgrades, like an outdoor kitchen, you can quickly exceed $50,000. However, this type gets the best ROI. You can expect to recoup your entire investment. In southern climates, you might even see up to 1.5 times return.

Cost to Build a Balcony

Building a balcony runs $15 to $35 per square foot. Third story or higher can significantly increase the price. You’ll often recoup the investment when it comes time to sell.

Other Additional Features

Additional features run anywhere from a couple hundred to a few thousand. Depending on your location, budget and tastes, consider the following upgrades:

  • Lighting:$8-$30 each. Post lighting runs $30-$100+ each. Light fixture installation costs can run another $150 each.
  • Heaters:$100-$300 depending on style and output.
  • Outdoor misting systems cost $1,800-$3,100.
  • Seating:
    • A “chat set” consisting of four chairs and a low table: $350.
    • Chairs, a sofa, some end tables and a coffee table: $4,000.
    • Bar counter: $500.
    • Awnings: $700 to $1,000.
    • Slipcovers: $20 to $250.
    • Replacement cushions: $30-$150.
  • Landscaping costs $1,500-$5,300.
  • Deck enclosure costs $8,000-$25,000.

Staining, Sealing and Waterproofing.

Remember to include the price of routine maintenance in your project budget. Most maintenance includes power washing and resealing, painting or staining.

  • Pressure washing costs $150-$400. You’ll want to do this prior to resealing or painting.
  • Deck staining costs $500-$1,000. For the DIYer, the price of stain is around $30 per gallon.
  • Waterproofing or Sealing a deck costs $550-$1,200. Sealer runs $20-$40 per gallon.
  • Refinishing a deck costs $300-$7,000. This will remove all old stains, sealants and paints and sand the surfaces smooth. Finally, the pro will repaint, stain or seal the surface.

DIY or Hire a Professional?

If you build this yourself and any part of the workmanship turns out to be faulty, you may be liable for any resulting damages or injuries. If you do decide to build one yourself, you should be aware of these common risks and pitfalls:

  • Uneven boards.
  • Rails and stairs that are improperly supported.
  • Inadequate foundation support can lead to bending and bowing, or even to a catastrophic collapse.
  • Building code violations costing time and money after it’s complete.

Find a professional deck installer near you today. Always read reviews and check references. In the end, you’ll know you have a professionally built deck that is safe for family and friends.

Cost to Build a Deck Yourself

It’ll run you about 65% what it would be to hire a professional. While material and labor are split about 50/50, you can’t purchase materials at the lower prices a contractor can find. Also consider your time. It’ll take 3-4 weekends to complete.

Getting a Professional Deck Quote

Getting professional quotes is easy. Browse our deck installation directory for reviews and ratings. Expect any reputable company to give free quotes. But follow these tips:

  • Never take a quote from a contractor who doesn’t visit the site.

What does it cost to install a veranda?

Total to install a veranda, or a roofed wrap-around porch, starts at $50 per square foot.

Note: If you’re looking for Veranda brand composite decking, that’ll run you $10 to $20 per square foot for both materials and labor, not including the foundation or framing.

What’s the cost of repairing or replacing your deck?

Deck repairs cost $700 to $2,500 depending on the severity of the damage.

What should I do before estimating deck costs?

Always create a comprehensive plan to start. Consider talking to an outdoor living designer, deck contractor or engineer to help with this process. By creating a mock-up and paying attention to specifics before you commit to a contractor or building plan, you'll save yourself the cost and hassle of changing your mind once the project is underway.

Follow these simple tips to get started:

  • Experts recommend creating a mock up.
  • Put everything you intend to have on your deck where it's going to go.
  • Mark it off and measure.
  • Leave it all in position and note how much sun your location does or doesn't get. If you get too much or not enough shade, you may want to rethink the location.

Rick Hogue More than 1 year ago
When budgeting for your outdoor living space, i.e. deck, arbor, gazebo, patio cover etc., keep in mind that the overall cost will vary depending on many factors. A simple ground level cedar deck without guardrail can be had for less than $20 a square foot. Elevated decks that by Building Code are required to have guardrails and decks with custom amenities such as seating, planter boxes, bar shelves, diagonal decking and skirting typically start at around $25 a square foot. Use of composite and hardwood material can add as much as 50% to any deck. The cost can be much higher in some cases. For instance many decks that we have built in the Texas Hill Country with homes situated on hillsides incur additional costs as the Building Code has specific requirements for elevated decks. Elevated decks that have skirting can also significantly increase costs, especially if the skirting is solid. We have built skirted decks where, due to the elevation, the overall square footage of the skirting was much more than the actual deck. In situations such as this the skirting costs can cause the per square foot cost of the project to increase dramatically. Some builders use predominantly 10' boards when building decks, this length of board is the most common and cheapest for the builder to purchase. So when they build decks exceeding 10' they will install a spline board where the two deck boards intersect. This method has many seams where the boards intersect and does not have as clean and finished of a look as using a single deck board. When you chose a contractor to build your deck insist that they use the longest board available to avoid unnecessary seams. You'll be much happier with the look of your deck. Another common practice most builders employ when building a 'cedar' deck is using the Treated Pine framing post as part of the guardrail system. They simply continue the Treated Pine framing post through the deck, add cedar rails and top cap. A 'cedar' deck with Treated Pine guardrail posts does not have that 'finished' look that most homeowners are expecting, but it's definitely cheaper for the contractor! Calling a deck 'cedar' using this method is somewhat disingenuous! If you are having a cedar deck built insist that your contractor use cedar for all materials above frame level. Again you'll be much happier with the look of your project. Also common with most builders when building steps is to leave a gap between the tread(where you step)and the riser(the vertical part of the step). It is cheaper for a contractor to build steps in this manor but it does not have that 'finished' look as a properly built step does. Insist that your contractor construct your steps properly. So you can see that there are many variables when it comes to budgeting for your project, including the contractors building methods. The most important decision when it comes to building your project should not be costs alone. A reputable contractor will build your project as if it were being built on their home and provide you with a dollars worth of value for every valued dollar you spend.

The price estimates are very optimistic (i.e., too low). I am having a deck rebuilt on an insurance claim. It is about 450 sq ft, attaches to second story of house, wraps around in an L-shape with one flight of stairs. The materials are standard Douglas fir (pressure treated, I believe). The price tag: $43,563.23, or $97/sq ft. That doesn't even include $2,700.00 for the design docs and blueprints. It blew my mind; I was thinking $10k - $15k. I thought someone was trying to rip me off but the second estimate I got was even higher. Plus, State Farm didn't bat an eye-- I assume that they would have balked if they thought the contractor was padding the estimate. There must be some major caveats associated with the estimates provided on this website-- maybe they are only covering materials, not counting building permits and inspections, etc. For comparison purposes, the construction is in Boulder, Colorado, 80302, and occurred in the winter of 2015-'16. I would love to hear your comments. Is this typical or am I (or, more precisely, StateFarm) being sodomized by the contractor?
James Helmuth More than 1 year ago
remember with decks that many variations can be made out of similar sizes. be creative to make it custom to fit your style if budget permits. slight changes make huge differences.

Hi Kathleen

I am interested in having my small deck replaced too, and  have the same environmental concerns as you do.  May I ask what  is your experience, considering your limitations?  I would consider some man-made product  depending on the source and the ecological  significancee.

Thank you.

Question: Is $18,500 a reasonable quote for a 16x12 PVC deck? Job will require removal of current deck (wood) 10x12. Material/Labor $12,000 and Overage/Profit is about $6,000. From what I have read, that seems like it's not on the same planet for a 16x12 deck.
