GREENSBORO, NORTH CAROLINA -- I purchased a 10 year old condo in a well kept condo subdivision. I have been very pleased in general, however the ChoiceDek deck is sagging, has splotches of black mildew, and areas of green mold/moss. When purchased, this was to be a no upkeep quality product. (My next door neighbor had it installed for his mother, and expected that it would give good service.)
Today I sprayed it with a deck wash product, scrubbed it, sprayed more. It is obvious that it is going to take multiple attempts to clean it. However, I believe I will not be able to get to all the black and green moss/mold/mildew that has been imbeded in the surface.
The product needs more drainage holes in the bottom rail, and needs better support of the railings.
Today while cleaning the railings, the post tops popped off (great glue), and I could see the name of the manufacturer on one of the remaining stickers. So I went to the website. Of course, it states that a new owner must notify them within 90 days. What if it's midwinter? What if the new owner has no idea what will be entailed? A very unfair warranty for a "no maintenance product".
Surely, this is a very misrepresented product!!
I am curious whether they are still selling these decks through Lowe's or any other outlet in Winston-Salem or Greensboro.

ChoiceDek NOT maintenance free
Posted by Prof. on 2009-04-24
NORTH CAROLINA -- Two years ago my husband and I installed a so called maintenance free ChoiceDek in two location in our back yard. Within a year black spots began to appear on the decks. Since we had recently had a new roof put on our home we suspected that a petroleum "drip" from the new roof might be to blame. We returned to Lowes building supply department and asked what could be causing the problem and they said yes it was probably the new roof and we would have to power wash the deck and all would be well. We did and it did look much better but within six months the black spots were back. After a second power washing it looked better again, but it was beginning to feather up.
Back to Lowes to hear that many customers had come in with such an issue and now there was a booklet about what to do (I was given no literature when we purchased several thousand dollars worth of decking material), they found one for me and I went home and read it and came to the ChoiceDek website and realized I was not alone. ChoiceDek claims that the black spots are mold and because we live in North Carolina we get mold. I was also told that I would have to scrub the deck with oxalic acid about every six months because of shade and humidity. One deck is in the shade and the other one in the sun and both get black spots. Has anyone picked off a small piece of the black spot and taken it to a lab to have it analyzed?
I believe that it is a residual from the formulation process and not mold. I am going to pursue this task unless someone tells me it has already been done and a result of testing tells us that the black spots are indeed mold.
