How Much does Composite Decking Cost per Square Foot?

The cost of composite decking per square foot varies depending on whether you are looking at materials alone or including professional installation.

Materials typically range from $4 to $12 per square foot, with premium brands like Trex and TimberTech sitting at the higher end of that scale due to their durability. When accounting for professional installation, which includes labor and additional components, the total cost generally falls between $30 and $50 per square foot.

Factors that can influence the final price include:

  • Deck size and site preparation
  • Regional labor rates (which may be 10-15% lower in the Midwest)
  • Custom features and the specific product line chosen

While the upfront investment is higher than traditional wood, composite decking is designed to provide long-term value by eliminating annual maintenance costs that typically range from $500 to $1,000 for wooden decks.
