New Trex Deck just installed with wood deck screws instead of composite- HELP PLEASE!
Our deck was just installed by a contractor who accidentally ordered non-composite deck screws. There is mushrooming occuring. Can he simply unscrew the wood deck screws and redo them with composite screws? If so, are there problems that may occur in the future?
I think the only way you could tell would be to try one. If the heads on the composite decking screws are larger in diameter than the ones you have already maybe it will make the effect less mushroomy. Maybe you can turn the boards over and screw them through the same holes?
If none of that makes sense, I'd make the dude replace the boards that he messed up, if mess up he did. Or if you're not that cold, you could just wait for the mushrooming to wear down from normal use...
I am a representative of Trex and would like to offer some input. You can remove the screws, though it will not be easy, and replace them with composite screws. We do make recommendation for screws we have tested that work well with Trex. Since mushrooming has aleady occurred, once the screws are removed, you may need to very gently tap the surface of the mushroomed area back down. If you want to speak to me directly, please contact me at 800-BUY-TREX.
I'm not a rep of a company, but I've worked with lots of Trex down in Port Aransas, Tx. I've gently used a 10lb sledge hammer (seriously, gently) to flatten the mushrooming effect. The stuff is pretty pliable.
