Trex Decking Cost

Trex decking costs $1,600 to $9,600, averaging about $4,800. That’s $5 to $12 per square foot for just decking boards and $5 to $15 per square foot for installation. Size is the biggest price factor, with 144 square feet ranging from $1,440 to $3,900 compared to $3,000 to $8,100 for 300 square feet. For a complete Trex deck, including framing, decking, rails and stairs, you can expect to spend $20 to $62 per square foot.

Trex is an innovative composite decking material that serves as a practical alternative to wood. It’s made of 95 percent recycled materials, like sawdust and discarded plastic bags. Each board has a high-performance shell that protects the core from termites, rotting, warping or splintering. And since the material never needs staining or painting, it’s virtually maintenance-free. Consider these cost factors as you make a choice.

Trex Decking Prices

Trex decking board prices range from $5 to $12 per square foot, depending on the series. Each product features a 25-year limited warranty, to help protect against material defects or fading. Your choice depends mostly on your budget and the color selection.

SeriesPrice Per Square Foot
Transcend$10 - $12
Select$7 - $9
Enhance$5 - $7

Trex Transcend Pricing

Trex Transcend pricing runs $10 to $12 per square foot. This series features the largest selection of colors and the best long-term performance with 0.94 inch thick solid boards. If you’re looking for an affordable and environmentally friendly alternative to exotic hardwoods, this may be a good choice.

Trex Select Pricing

Trex Select pricing ranges from $7 to $9 per square foot. This series gives you more color choices than Enhance Basics, but it’s less expensive than Transcend.

Select features slightly thinner boards at 0.82 inches. This design makes a seamless installation quicker and easier. It also means that you can’t mix and match with Enhance or Transcend.

Trex Enhance Cost

Trex Enhance costs $5 to $7 per square foot. This product comes in two styles, Naturals and Basics. Both have a thickness of 0.94 inches, but with a scalloped bottom which reduces weight and price. Naturals offers a mid-grade option with two extra colors and come in a natural wood grain finish. Basics limits the selection with a more synthetic appearance for as low as $5 per square foot.

Trex Price Per Linear Foot

Trex prices range from $10 to $24 per linear foot. With Trex boards measuring 5.5 inches wide, one square foot of board roughly translates into two linear feet.

Keep in mind that this comparison relates specifically to Trex’s board width. Deck products that are narrower or wider use a different calculation for linear feet.

DIY vs. Hire a Trex Installer

Trex boards are built for easy DIY, but that doesn’t mean anyone can do it. A deck needs a substructure that can support weight without shifting, and installing one usually requires a professional. When you’re ready to contact composite decking contractors near you, plan to:

  • Read ratings and reviews.

  • Get an in-person consultation, in case your yard needs extra work.

  • Request estimates from at least three pros.
