I was talked into using Duration on the wood siding exterior of my house by the Painting Contractor and Sherwin Williams Saleman. After just 1 year I noticed cracking and checking on my siding. The third year I tried to contact Sherwin Williams Company regarding the lifetime warranty, no reply was received. The forth year after the initial install I, after a lot of phone calls and e-mails a Sherwin Williams representative contacted me. He tried telling me it was moisture, type of wood, and several other scenarios that I shot down because of the fact this was happening to my original house, addition and garage. Finally they agreed to replace the product. They also instructed me to use wood filler and primer to prep the damaged surface. Just 1 year later the damage returned, and deja vu, no one has returned contact.
Has anyone else had this problem with Sherwin Williams Duration and wood siding?
