Trex and TimberTech both build good boards — but they aren't the same product. Here's how the two compare for a deck that has to live through a San Antonio summer.
Last updated: October 2026
Trex and TimberTech are both strong choices for composite decking in San Antonio, and the right one comes down to which product line fits your deck, your color choice and how you use the space. Both make capped composite boards — a wood-and-plastic core wrapped in a protective shell that resists fading, staining and moisture. TimberTech also makes capped PVC boards with no wood content at all. For most South Texas backyards, the bigger decision isn't the brand — it's the board line, the color and how the deck is framed.

Which Composite Handles Texas Heat Better?
All decking gets hot in direct South Texas sun — composite and PVC included. Color matters more than brand here: lighter boards stay noticeably cooler underfoot than dark ones. If your deck faces west or sits in full afternoon sun, we'll talk through lighter colors, shade from a pergola, or both.
What Matters More Than the Brand?
The framing underneath. Composite boards last for decades, so the substructure needs to last just as long — proper joist spacing for the board you choose, solid footings, and hardware that holds up to Texas humidity. That's where a lot of composite decks go wrong, and it's covered in more detail in our post on the #1 composite decking mistake.
Which Should You Choose?
- Choose Trex if: you like one of its color lines and want a proven capped composite board.
- Choose TimberTech if: you want the option of a capped PVC board or prefer one of its multi-tone looks.
- Still torn? Look at samples outside in your own backyard light — color in the sun is the tiebreaker for most homeowners.
