I want to thank UltraWindows and all others who gave me advice and assistance on new windows and patio French doors for my home. Initially, I was going for fiberglass or vinyl; however, After so much research for my area (North Central Texas), I decided that neither vinyl or fiberglass would be optimal. Got in touch with Don Young regarding their thermally-broken aluminum windows; their windows were installed last Thursday and Friday. The installers, Ben and Peter, were extremely professional and worked as a well-oiled machine together. They were great! So thank you again UltraWindows and thank you Don Young and thank you Ben and Peter.
