Please do not let this thread turn into "my Trex deck is horrible" thread.
My question is about ensuring water runoff. After 7 years i have several series of decking that has lost its gap between the boards. Thus the water cannot drip through and based on what i've read about Trex the worst thing you can do it is let the water sit on it.
Either the decking has swelled over the years slightly, or shifted, but I have about a half dozen spots where 3 or 4 boards are butted side by side and no water can drop through).
Unscrewing the boards and respacing is not an option since the ones that are touching are in the middle of about a 25 board run.
I'm thinking about drilling some sort of drain holes here and there to allow water to drip down. Do you guys have any good or bad feedback on this?
I don't believe Trex is like TP wood where if you break the surface or cut it you compromise the integrity of it.
