"Fantastic service from start to finish. I had several windows installed by Stuart and he was always on time, very efficient and answered any question I had. He always cleaned up when he left for the day. He made sure I knew how the windows work before he left on the last day of the install. This is the second time I trusted Window Tight to install new windows for me. I definitely recommend them to anyone needing new windows."

"Excellent contractor . Great to work with . B & K replaced the window glass in Five Thermopane windows. The window frames were still good so that is why I chose the glass replacement option. Cost, of course, is then far more reasonable. Our windows now are clear - no fogging anymore."

Customers say: Terrific value
"I have an older house with some "troublesome" windows. The gentleman did a thorough job of cleaning them. He also was very patient with some of the problem windows. I was very pleased with the care he took in putting screens and storms back in the window frame. I would recommend him highly."

"By far, Window Concepts beat out 3 other local companies in price. I needed new windows and patio door bad, but I didnâ t want to sell my first born to get them! Iâ m very, very pleased with my purchase and the crew who installed them were excellent. They worked together well, very clean and considerate. I will definitely suggest Window Concepts to anyone who needs new windows! Thank you!!!!"
