Just had 11 windows and 3 patio doors replaced by Windows of Greater Tucson. Pat came out personally to show us the product and give us a quote. He knows windows and doors. VERY reasonable. EXCELLENT quality product. The installation took two days and the crew was professional and friendly, and did a terrific job of cleaning up afterwards. The house is much quieter and I anticipate excellent energy savings as these are energy efficient. Having a bit of lightning and thunder outside which our dogs are usually terrified of but we hardly even hear it now. Thank you Pat and crew!
