Why is my Trex deck warping?
Warping occurs when the decking's surface is exposed to sunlight. The decking becomes hot and starts to distort gradually. It happens during thermal expansion when the decking absorbs heat from the sun and expands. The heat from the sun causes the decking to be flexible.What causes composite decking warp?
The reason why most composites warp is due to thermal expansion. When plastic fibres of the composites get heated, they will expand. It will return to its original size unless there's a problem with the decking board spacing.Should composite decking warp?
Your composite deck may not warp, but it can sag and buckle. Most sagging is caused by improper spacing between the joists when it is installed. Also, thermal expansion, the fluctuation of temperatures, can have a more significant effect on composite decking than on natural wood decking.What are the disadvantages of Trex decking?

Why is my composite deck wavy?
Flatten Joists to Avoid a Wavy DeckMost PVC and composite products aren't as rigid as wood, so they don't bridge imperfections in the framing as well. If some of your joists are higher than others, you might end up with a wavy surface.
Does Trex decking float?
Water ResistanceBecause plastic decking is lighter per cubic inch than wood, it will float easily. There are no micro-spaces for the water to seep into, which means that the material will float indefinitely.
Does Trex deck swell?
All of our composite deck boards have been engineered with the changing weather conditions in mind, meaning they can withstand whatever's thrown at them a lot better than real wood can. Composite decking doesn't swell or contract to the same extent that real wood decking does (especially if it's fitted correctly).How long does Trex deck last?
Trex and TimberTech Composite Decking WarrantiesComposite decks have a lifespan of at least 25 to 30 years — and they have warranties to match. At Keystone Custom Decks, we primarily build using Trex and TimberTech composite decking products.
Does composite decking twist?
Composite decking has a high rate of expansion and contraction due to temperature swings. It actually moves greater distances and more unexpectedly than traditional wood. When the boards expand and contract, they may split, delaminate, and peel. The movement can cause your decking to shrink, warp, twist, and bend.Is Trex decking worth the money?
Trex decks are worth it because you get what you pay for. They cost more than a treated lumber one, making up for your extra outlay of cash at the onset, and will last for years longer than the average treated deck, letting you more than recoup your investment. Trex decks are also low maintenance.How do you straighten a warped composite deck?
Cut off the warped partWhen the composite decking warped, we can see that it's mainly the end part warped. So it just needs to cut the end warped part off. Then, we can put the same new decking board onto the empty part only. Please make sure that there is a suitable joist frame under the old and new decking.
