I installed a 12' x 30' deck using Trex Brasilla Cayenne in September of 2007. We purchased your product over IPE wood due to the performance claim of low maintenance and the 25 year warranty. Now about a year and a half later we have black mold covering the entire deck.
Trex responded with a "free" cleaning kit. I applied the cleaning solution as directed. It did clear the deck of mold for a few weeks but it's back worse then before. But it also made the product lighter in color.
Contacted Trex again in 2011 asking for compensation to replace the defective Trex Brasillia product. We received a letter back in November 2011 stating "they take their customers very seriously and carully examine all presented material to determine whether a condition falls under a Trex warranty".
They went on further to explain that "mold and mildew grows on all decking materials but the performance of the deck is not affected". [continued below]....
..... (What a joke) "Trex does not warrant against and is not responsible for any condition attributable to environmental conditions such as air pollution, mold, midew, etc."
They went on to say:
"However as a good gesture, Trex offers to arrange for the deck to be professionally cleaned." "Please accept this offer as a resolution to your concerns with Trex deck. Please sign the letter below and return to Trex. Upon receipt. a cleaning contractor will be supplied and will contact you to make arrangements"
If I signed this it would absolve Trex from any futher obligations. Needless to say I did not sign the letter. Do you research prior to choosing your deck material. My advice is to avoid any Trex product.
