I recently purchased a house which was built in 1996. All the windows are Peachtree and I assume were installed new in 1996. All of them have bad seals to the point you can see daylight through what would normally be an airtight seal. Also there is discoloration on the inside of the double pane windows. There are 37 windows in this house and ALL need to be replaced. I just received a quote of $40, 000 to replace all the windows. The previous owners (also the original owners) passed away 2 1/2 years ago after lengthy illness and should have but may not have filed a complaint against Peachtree. Karl Davis
