I bought windows for my 1st house over 7 years ago from Thermal Windows, Inc., and they did an amazing job. I am very detail oriented and I could not find one thing to complain about, on the contrary they were fast, courteous, and very good! I just bought a new house a little less than a year ago and have just purchased windows to go in this home as well. After we accepted an offer on our 1st house we noticed that the big circle top window had a small hole in it from a rock hitting it. I called Thermal Windows, Inc, and expected to pay a lot of $ to fix it so that I could close on the house, but they said I am covered even from accidents on broken glass! They came out 2 days later with new glass and installed it in less than an hour. When they left it looked as if no one had been there, and I was able to sell the house without any delay! I have already recommended Thermal Windows to all of my family and any of my friends that are thinking about replacing them.
