What is composite decking? Composite decking is usually a blend of recycled wood and plastic materials that provides a low-maintenance, long-lasting decking solution for residential and commercial clients. 

In contrast with wood decking, composite materials resist insects and rot, don’t splinter, and come with stain and fade protection to maintain their natural wood appearance for many years

In addition, most composite decking materials come with manufacturer warranties of 25 – 50 years and don’t need an annual stain and seal. For these reasons, composite decking has gained significant traction in the decking market since its inception in the mid-’90s.

Composite Decking Cost Estimator By Size

As with standard deck costs, size and materials may be your two most important variables, aside from labor. Composite decking typically costs $25 – $50 per square foot. If these prices seem outside your range, keep in mind that choosing a basic deck design, reducing your deck size, and choosing different product lines can lower your upfront costs.  

Deck SizeTypical Cost 
12 x 12$3,600 – $7,200
16 x 16$6,400 – $12,800
20 x 20$10,000 – $20,000

Other Factors That Affect Cost

Aside from size, the cost of composite decking is also impacted by the following factors:


Here is a sampling of decking material costs per square foot by the manufacturer. Note: These are costs for the deck materials only. Railings and costs for the fascia and substructure components (posts, joists, beams, etc.) are not included in these figures.

BrandTypical Cost / Sq. Ft.
FiberOn$4.48 – $13.18
TimberTech$7.15 – $13.40
Trex$5 -$11


Aside from composite decking material, you will need additional materials to build a composite deck, including:

  • Composite deck boards
  • Railing
  • Posts
  • Hardware

Brand and quality also affect the cost of additional materials.

Maintenance Costs

Here is another perk: Composite decking boards require very little upkeep. If you are tired of the annual wash, stain, and seal, that alone may be enough to make you a composite convert. To maintain a composite deck:

  • Sweep the deck as needed
  • Hose off spills as they happen
  • Use a mild soap or store-bought composite cleaner once or twice a year
  • Depending on the particular brand of material, you may be able to use a pressure washer as needed.

Shape and Angles

A standard rectangular deck is the cheapest option. From there, more sides and more complexity lead to higher costs. Intricate deck designs require more labor (and skill) than simple shapes. Your contractor will have to cut and measure every angle. 

Prep Work

Before the crew can start on your deck, they may need to prepare the work site. Prep work may include:

  • Deck removal: If you are replacing an existing deck, expect to pay $5 – $15 per square foot for deck removal.
  • Grading and leveling: You want to build your deck on a flat-level service. Expect to pay $0.40 – $2.00 per square foot for leveling and at least $500 for grading. 
  • Substructure construction: If you do not have an existing base for your deck, one will have to be constructed. Expect to pay about $4 per square foot.
  • Land clearing: If there are trees and other vegetation that needs to be cleared, you will have to add the cost to clear land. Expect to pay about $1.18 to $2 per square foot.


Here are a few of those little extras that may add to the overall project cost:

  • Furniture: Once your new composite deck is in place, everyone will want to visit, so plan on buying some new furniture for your friends and family to enjoy.

    A basic table and two chairs will run about $100, and it goes up from there. Sectionals, couches, and lounge chair sets will easily cost several hundred to several thousand dollars.
  • Lighting: If you plan to do outdoor entertaining on your deck or are concerned about safety, lighting is probably necessary. Ask your landscaping contractor about a lighting package. This will run an extra $1,500 – $3,000 on average.
  • Roofing and awnings: For some decks, especially attached structures, a roof is a nice, or in some climates, a necessary addition. Costs range from $2,500 to about $10,000.

    If awnings are more your style, the average awning installation will cost around $2,500, while prices can range from $1,300 to $4,000.

Home improvement projects are usually multi-faceted, and deck builders are often part of larger landscaping firms that offer many types of outdoor services. Here are a few extra projects you may consider to enhance your outdoor space:


If you’ve got a beautiful new deck, you need a landscape to match, or at least a pretty area to border the deck. Many homeowners install softscaping areas around the deck complete with mulch, flowers, bushes, and perennials, depending on the size of your deck. Expect landscaping costs to run between $5 – $24 per square foot for this service.

National Average Cost$12,825
Typical Price Range$4,000 – $20,317
Extreme Low-End Cost$2,000
Extreme High-End Cost$38,333

Fire Pit

Fire pits add warmth, light, and ambiance to any outdoor living space and most fire pits cost $240 – $2,400. Prefabricated above-ground fire pits are the cheapest and custom-built in-ground fire pits cost the most.

National Average Cost$850
Typical Price Range$240 – $2,400
Extreme Low-End Cost$200 
Extreme High-End Cost$5,0000

Hot tub

Many homeowners put a hot tub on their deck and most hot tubs cost $4,500 – $10,000.  Inflatable hot tubs are the cheapest, but they also have the shortest lifespan. Acrylic hot tubs can be pricey, but they are energy efficient and durable.

National Average Cost$6,900
Typical Price Range$4,500 – $10,000
Extreme Low-End Cost$1,000
Extreme High-End Cost$25,500

Paver Driveway

Paver driveways are durable, attractive, and do wonders for your curb appeal. The typical cost of a paver driveway is around $5,500 – $26,000.

National Average Cost$13,000
Typical Price Range$5,500 – $26,000
Extreme Low-End Cost$2,000
Extreme High-End Cost$64,800

Note: If you are in the market for a new driveway and pavers are out of your budget, the typical cost of a concrete driveway is much less and they are also pretty durable.

Sprinkler System

Sprinkler systems are an efficient and convenient way to care for your yard’s catering needs.  Most sprinkler systems cost $2,400 – $4,200.  Prices vary depending on the size and makeup of your lawn and the sprinkler system type. 

National Average Cost$3,150
Typical Price Range$2,400 – $4,200
Extreme Low-End Cost$825
Extreme High-End Cost$8,300

Pergola Installation

Pergolas are semi-shaded outdoor structures that are affordable and can even be built DIY. Typically, a professionally installed pergola costs about $4,000.

National Average Cost$4,000
Typical Price Range$2,100 – $6,000
Extreme Low-End Cost$1,050
Extreme High-End Cost$11,000

How to Install a DIY Composite Deck in 10 Steps

Installing a composite decking system, according to one manufacturer’s website, is similar to installing a wood deck. However, there are a few manufacturer specifications that you will need to follow. 

Just make sure you read each manufacturer’s installation guide. Most manufacturers have a YouTube channel as well, to make the process easier.

This is a rough outline of how you may go about installing a new composite deck:

Step 1: Be sure to check with your local building department to get code requirements. Also, check with your HOA, if applicable.

Step 2: Create your blueprint.

Step 3: Check with your insurance company and tax assessor’s office to inquire about how a new deck may influence your homeowner’s policy or tax responsibility.

Step 4: Apply for a building permit and inquire about the inspection process. 

Step 5: Call 811 to have your utilities department mark utility lines before you dig.

Step 6: Grab a friend (or two).

Step 7: Do any needed site preparation.

Step 8: Install your deck.

Step 9: Pass the building inspection.

Step 10: Enjoy the fruits of your labor.

DIY Cost vs. Professional Service

Materials are about the same as labor costs, so if you have all the equipment, expect a DIY composite deck to cost about half of professional decking prices. However, if you don’t already have the tools and heavy equipment, you can catch up quickly to the price of professional installation. 

Cost of a Composite Deck By Location

Just as with wood decking materials, composite decking material costs can vary by location:

  • Taxes: Any new home addition can affect your property taxes. Contact your tax assessor’s office while you are in the planning stages of the project for more information.
  • Insurance: You’ll want to ask your insurance company if your new addition will be covered under your homeowners’ policy and if this capital improvement will increase the cost of your policy.
  • Permits: Unless you are building a very small or ground-level deck, you’ll probably need a building permit. Application fees are usually required. (Check with your local building permit office even if you’re building a small or low deck just to be safe.)
  • Installation costs: Areas with a higher cost of living typically have higher installation costs. Supply and demand can also affect installation costs. For example, if a hurricane recently hit your area, contractors are very busy and likely to charge more for elective services.

FAQ About Composite Decking

1. Are there any precautions I need to take when cutting composite decking materials?

Yes. Just as you would do when cutting wood, you need to wear a mask, safety glasses, and probably gloves as well. Also, composite shavings cannot be left on the ground to biodegrade due to their plastic content.

2. Does composite decking have a natural wood look?

Most composite materials do have a very natural look to them, but you may find that as the cost increases, the appearance improves as well.

3. Will composite materials accommodate curved design plans?

Yes. Synthetic decking can be curved. Check with your landscape architect or contractor to make sure this detail is considered in the early stages of the design process. There is more than one way to do this depending on the design and equipment available.

4. Is composite decking or wood better for cold climates?

If you are concerned about the weather in your area, composite decking may be a good choice. If you live in a cold climate with heavy snow or if you live near saltwater, composite decking is often preferred over pressure-treated wood or other real wood due to its ability to resist harsh wear and tear from the elements.

5. What is the difference between “capped” and “uncapped”?

Another note on durability: Look for capped vs. uncapped composite decking. Most boards today come capped, but double-check. Capped boards have an outer coating that is bonded to the board’s core, giving it extra protection against the elements. 

6. What type of warranties does composite decking come with?

Composite decking wins in the “best perks” category. Looking for a warranty on your investment? Composite decking comes with manufacturer and fade/stain warranties of 25, 30, or even 50 years depending on the product line.

Certain product lines even come with a limited labor warranty if your contractor meets certain requirements.
Note: Most composite manufacturers specify the type of nozzle and PSI, though, as failing to follow these specifications may damage your decking and void your warranty.

Final Thoughts

If you are interested in a low-maintenance, durable deck system, composite materials are worth your consideration. A composite deck may require more upfront costs, but with their warranties and minimal maintenance, they are worth the investment.

In addition, composite decks are a great way to allow you to enjoy the outdoors. Contact a local composite decking pro today to get a quote!
