HORRIBLE company - stay away from these crooks!! My builder used them for our new house, but when it came time to warranty repair every window in the house because they all leaked & turned cloudy, it was very difficult to get in touch with anyone, when I finally did, they sent someone out to survey replacing all the windows - he measured every single one - they charged my credit card for the labor replacement cost under warranty, but when they came out, they only brought half of the windows, stating that was all they had on their order and that was all I had paid to replace. They even broke a few while installing, came back, broke some more while replacing and have never been back or responded to my calls since.
