What will it cost to build a Trex deck?
A Trex deck is made out of a composite material that will bow if not built correctly. It needs to be installed on a sub frame that will properly support the decking material. The sub framing of our decks is built with pressure treated lumber, the deck hangers are spaced 16″ on center and all of our Trex deck layouts are built in the “pitcher frame” boarder pattern.
A basic 12×12 Trex deck with no railing or steps will cost no less then $10,000. That works out to around $70 per square foot.
The Sub framing system is built with nothing less then 2×8 pressure treated lumber.
