COMPOSITE DECK FAQ’S
That’s the guarantee. Most composite decking manufacturers provide 20-25 year warranties on their product against the occurrence of splintering, warping, cracking and rotting.
Yes and no. Older composite decking materials (e.g. manufactured in the late 90’s) were especially vulnerable to mold and mildew development. Improvements in manufacturing have largely eliminated these problems, though poor deck construction can still contribute to them. Mold and mildew is most likely to occur in areas where water collects and pools for extended periods of time on the composite material. Composite decks should be constructed with a slight tilt away from the home into the yard, allowing for proper water run-off and drainage.
This varies by material, but in general the answer is yes, composite materials will fade initially. Over the first ninety days of your composite deck’s exposure to the UV rays from the sun, a slight fading process will occur with many brands. This will change the colour of the deck, giving it a more natural “weathered” look. Once the initial weathering process has occurred, composite material is remarkably resistant to further fading. Low grade composite material, however, is susceptible to higher levels of fading over longer periods of time, often turning a greyish or pinkish colour.
The flipside of the fact that composite decking doesn’t need to be stained is that it can’t be resurfaced or (intentionally) stained like pressure treated or cedar decks can. If you spill grease, paint or red wine on your composite decking, be sure to clean it immediately, as there’s no easy way to remove or fix stain spots on a composite deck.
Compared with its natural alternatives, composite decking requires very little in terms of upkeep and maintenance. The most important maintenance measure you can take is to sweep your composite deck.
