"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."

"We highly recommend Empire Home Remodeling. They replaced all the windows in our home. Outstanding product and customer service. Professional and personable from start to finish. They showed up on time, as promised, and replaced all 20 windows over the course of 2 days. We couldn't be happier! Our new windows are not only the most energy-efficient on the market, but gorgeous as well!"

"They were very pleasant and very meticulous. My windows have never been this clean. They cleaned the windows, screens and wiped out the window wells. Were there for a long time but cannot really complain as they provided a wonderful service!"

"They really go after you for the sale but after the sale is made they really fall apart. I got an email that my windows were ordered over a week after I ordered them, and an email 5 or 5 weeks later saying they came in. It took them another month to install them. Nearly all the quotes I got were the same but Empire used ?sign now? tactics to get my sale. If I could go back I would not have signed for the small discount and I would have gone with another company offering the same price with no pressure. My windows are fine and the subcontractors that they sent to install them were friendly."
