Common complaints about Trex include that the decking has a fast development of mold and a short lifespan. Other people complain that the deck becomes too hot to walk on in bright sunlight or that the boards become warped, according to Consumer Affairs.
On Consumer Affairs, as of June 2015, Trex decking received more than 30 negative reviews. Each review stated problems like discolored and warped boards after only one year, green and black mold growth and holes in individual boards.
These problems occurred despite the company advertising its decking products to be "beautiful" and "maintenance-free." Several customers complained that trying to talk to the company about its warranty was met with little to no recourse.
