I purchased Peach Tree windows and doors for my home in 1990. My windows are sweating between the panes and I had one window pane to crack that one I had a contractor to replace. My Patio door is rusting - put they say my life time warranty is not life time of my home but the pro rate the life time to be 10 - 15 years. Now I have windows in my home that I am very dissatisfied with. Every contractor I have talked to states that Preach tree is a very cheap product and the sizes are not the standard size.
