How Much Does Composite Decking Cost? 

The most common question we hear is, how much will it cost? But when it comes to composite decking costs, it’s hard to give a definitive answer.  Relatively, composite is less expensive than PVC, but more expensive than wood.  

There are also a number of companies manufacturing composite decking – and each brand has multiple lines (or collections) at different price points. 

At The WoodSource, we offer three brands of composite decking: Trex, TimberTech and Fiberon. Trex is generally the least expensive and Fiberon the most expensive.

How Composite Decking is Priced

Composite decking (like all decking material) is priced by the linear foot, and the price between brands and collections can vary significantly. For example, in 2021, our composite decking prices ranged from $2.72 a linear foot to $8.75 a linear foot.

The price per linear foot depends on a variety of factors:

  • Volume of Material: Scalloped boards cost less than solid bottom composite deck board because they have less mass.
  • Texture Complexity: Deck boards with complex textures will cost more than decking with simple patterns.
  • Colour Complexity: Lower cost composite deck boards will usually have more monotone colouring, while more expensive options will have sophisticated colour variations.
  • Capped vs. Uncapped: Most modern composite deck boards are capped; however, not all are capped on all-sides. Four-sided capped composite deck boards will cost more than the more economical three-sided capped composite.
  • Warranty: Comprehensive warranties can help you save money in the future, but will also increase the price per linear foot.

Determining Your Composite Deck Cost

To figure out how much a composite deck will cost, you need to determine how many deck boards you’ll need for the project:

  1. Calculate Deck Square Footage
    Multiply the length by the width. Don’t forget to include stairs!
  2. Determine Board Square Footage
    Decide on the board length you’re going to use, and multiply the board length by its true width.
    Make sure to convert all board measurements into feet before calculating.
  3. Divide Deck Square Footage by Board Square Footage
    Take the area of your deck (calculated in step 1) and divide by the board area (calculated in step 2). Round up to the nearest whole number, and that’s how many deck boards you’d need!

Using the above method will give you an approximation of how much decking is needed for the project; however, before purchasing, make sure to account for deck board spacing and waste/off-cuts. It’s always a good idea to add a buffer into your decking material order.
