We built in 2000 and was not finished till 2002. We purchased windows from Home Depot (Silverline windows) We have a lot of problems with parts breaking. The first few times they sent someone to fix them, now we only get the parts. They charge $150.00 to send someone to fix them. My problems have been a small plastic part that holds the screens in just fall out. They have changed the design now but that is to late for me. The window guides and the part that holds the window in the frame break. They just sent me replacement parts that are wrong. It is complicated and I don't know how they think you can fix them yourself. I would never purchase windows from Silverline again.
