We bought our windows 17 years ago. I will never forget the day they installed them, it was storming. They were so quick, they somehow kept the rain out, while installing. This was one of the best purchases we’ve EVER made. These windows are everything promised and MORE! You will never regret your investment. I have seen hail the size of golf balls hit them and not leave any damage. I can’t say enough about their quality, I mean 17 years!!!!
