I stumbled upon this website the other day which has long list of Trex customer complaints regarding their Transcend line.  It's the same story, persistent mold that leaves the owners feeling frustrated and powerless against a company that really doesn't give a rip about customer service or keeping the customers best interests in mind.  I see my "friend" Brittany from Trex has responded a couple of times on this message board.  I think Brittany was the one who ultimately booted a bunch of Trex naysayers off of their Facebook page which in turn spawned the very blog you are reading now.

Please share your experiences on Plumb-n-square's website to get the message out.

Thanks!
