We had five windows replaced about eight years ago by Champion. There are warrantied against failure for life. All five windows have failed and are foggy. One even has insects in between the panes of glass. I called in the beginning of November to get them replaced. The receptionist at first seemed so nice and so polite and told me she would order new windows and we would have them fixed in about six weeks.That was four months ago and today I was still told it would be another month, so much for a warranty. Avoid Champion Windows. I just looked at the BBBs rating for them and they have an A+. How can that be when I see complaints all over the internet about the company?
