FAQ

Wood or gas fire pits should not be placed on top of Trex decking. However, gas fire pits may be installed beside or between deck boards with a protective wall made of stone or other fire-resistant material used for insulation. Wood burning fire pits should not be placed on top of Trex decking unless installed with DeckProtect™, a product designed to temper extreme heat and loose embers.

With pressure-treated wood decks, maintenance costs add up over time.

Although Trex costs more initially, you'll never have to sand, stain or paint your Trex deck. Over the life of your deck, those reduced maintenance costs add up to a greater value than wood—not to mention the value of the added time spent enjoying your deck rather than working on it. If you would like to see the difference in maintenance costs for your deck of wood vs composite, visit our Decking Comparison page.

Calcium chloride or rock salt can be used to melt ice and snow on Trex decking. Care should be taken to rinse off when the weather makes this practical. Use plastic shovels (never metal) to remove snow and ice. A metal shovel can possibly chip the decking surface and void the warranty.

Trex has recently engineered a new line of composite decking, Trex Transcend Lineage, which is designed with heat-mitigating technology that makes it our coolest decking yet*. Like many other outdoor surfaces, such as concrete, asphalt, beach sand, wood decking, other brands of composite decking, etc., Trex decking can get hot due to weather and sun exposure. On such days, care needs to be taken to make sure skin does not have extended contact with the surface of the deck, especially with young children and those with special needs. If you are considering our traditional decking boards, please note that the darker the color, the hotter the deck will feel. For hotter climates, consumers should consider choosing a lighter color. *Although Trex Transcend Lineage is designed to be cooler than most other composite decking products of a similar color, on a hot sunny day, it will get hot. On hot days, care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.

Trex decking requires far less maintenance than wood decking, but does require some maintenance to keep it looking good throughout the years, much like washing your car. For early generation composite decking (Trex Accents), periodic cleaning with a deck wash is required. Trex high-performance decking (Trex Transcend, Trex Enhance and Trex Select) require less work - a simple soap and water cleaning is all that is necessary to maintain the beauty of the products. Refer to our Care & Cleaning Guide for more information on upkeep.

Newer-generation Trex decking holds strong against potential damage. All of our current decking lines are scratch resistant, protecting your space against nicks, cracks and splitting. For more information, see our 2023 Limited Warranty.
