"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."

"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."
