We have pro finish single hung windows as well. We are having terrible problems with these windows. We even have ice forming on the inside of the windows as well as a terrible draft. We have tried numerous times to get help from Simonton. They insist nothing is wrong with the windows and they are incredibly rude to deal with.
Our home is only three years old and the simonton reps continue to say there is nothing wrong with the windows.We need some expert advice...Please!
