We, too, have the Desert Bronze deck which was installed in July 2009 shortly after we moved into our new home. Nearly $16000 later we are beside ourselves in buyer's remorse as our beautiful deck has become an eyesore with the white chalking and the blackening of the boards. When I was at Lowe's yesterday to see about a deck wash, the salesperson suggested I go on the TT website because he had heard that there were several lawsuits being filed against TT for the very same problem we were having and that no cleaner would even touch the problem. So today we filed our claim with TT and intend to write a letter to the Better Business Bureau to ensure they lose the A+ rating (which is unbelievable) and also to our Attorney General in Missouri. We also included in the content of the claim that we had been in contact with other dissatisfied TT buyers and did not expect to be put off for six months. We will let you know what happens. We will not use any kind of cleaner on the deck as we do not want them to claim our cleaner caused damage. This is just unacceptable in this day and age to get this kind of treatment so we will certainly enjoin a class action suit if it comes to that, but we all know that our share would amount to about 28 cents and the rest would go to the attorneys, so that would be a last resort only to put TT out of business. Good luck to all of our fellow abused. Hopefully we will all get things settled or we may have to take our photos and go to Fox News. Wouldn't that just frost TT?
