I had (6) windows put in by Champion windows of Omaha nebrasaka 3 years ago and have had nothing but problems with them leaking air. The sevice techs have come out numerous times and tried all kinds of band-aid fixes that never work and have finally told me there is nothing more they can do to fix them. Their sales pitch is "we make the windows we install the windows and we stand behind the windows" their warranty states life-time warranty for as long as you own the home. I finally filed a claim with the BBB of Omaha ne, on my first writting to the BBB and Champion windows the BBB said that Champion had 30 days to respond to my claim. Well after the first 30 days and no response from Champion windows of Omaha Ne the BBB sent them a reminder and it took them another 30 days to respond by telling me that their windows are not aquriums and that all windows leak air. The salesman who sold me the windows never stated that all windows leak air (would anyone buy replacement windows if the company stated that they leak air) he stated that they would stand up to anything mother nature could throw at them. Well my windows leak and we have had to put plastic over them (imagine replacement windows with plastic over them) every winter while Champion windows of Omaha plays games trying to fix them with band-aids. Well we took video of the windows and how they balloon out when the wind blows and I even went as far as to buy smoke sticks to test for leaks in your home. We took video of the smoke test too, and have asked the owner Alan Freil of Champion windows of Omaha ne to look at the videos. We get no response from Alan Freil of Champion windows of Omaha ne accept to hear that windows are not aquariums " Well Alan if your windows were aquariums all my fish would be dead, there would be no water in them, and no aquarium installer to stand behind his product. Alan Freil did not have any problems cashing my check for $4000.00 but I sure get the run around when he sells windows and the grand warranty that is no better than the paper it is written on. I have also e-mailed their corporate office and you can guess what type of response I got from them (NONE). Consumer beware of Champion windows and check all the complaint internet sites you will be suprised by what you read about Champion windows, wished I would have checked before being taken by Champion windows of Omaha Ne and owner ALAN FREIL.
