I built a Trex deck 11 years ago. Except for pressure washing it a couple of times, I did not do anything to it. I live north of Philadelphia and the deck was always in the sun. So it saw weather. I loved it except for the occational chunks of plastic. So here I am building a new house an now thinking of using EPOCH. Only because it looks better. It also appears to be cheeper. Until this posting I never heard of any complaints. I am also interested in any other comments that people might have on these products.
