Windows have lost their seal.. Patio doors have lost their seal as well and Peachtree was lifetime warranty and Company that purchased will not Peachtree is giving everyone the run around and will not honor it. All of our windows/doors 23 windows/bay window/Patio Door were purchased from Peachtree in 1992.. Yes thats been a while but we take great care of our house first and only owner, we built ourselves. We cant even see out of the bay windows nor patio door. It looks just nasty.
