Outstanding...... Bought 14 windows and a door from Best Windows and Doors. Great value and great service from start (initial sale - they were one of 3 bids), through installation. The installation team of 5 did an outstanding job of removal, installation, doing custom trim, and cleanup. We were very impressed with the teamwork of the installation crew and would recommended Best and their team to anyone. September 20, 2014

Best SGS Provides Outstanding Products, Installation, and Service Everyone at Best SGS goes out of their way to ensure complete customer satisfaction. It starts with the sales person, and continues through product ordering and installation completion. The office is equally driven to make sure that the customer is satisfied. Attention to detail ensures that the customer receives the product expected, and the installation team completes the job quickly, professionally, leaving no hint that they were ever there....except for the new, beautiful windows. I highly recommend the Best SGS Team. December 8, 2013
