All Weather Windows

We built a brand new home and orderd all our window and doors from All Weather Windows out of Cananda. About three months after we moved in we had one window that you can not see out at all because it is all fogged up and a french door that leaks and is also foggy. I tried to contact them by email which apparently was a mistake! They started out really nice that they wanted to help and then just gave me the run around. I have never got them to do a thing about their windows because they quit responding at all. I would not recommend these windows if they were the last company in the world!
