"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."

"We had two windows replaced and they look great. We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter! The windows that we ended up getting have features that we didn't have before and we love it all - the ability to move the screen up and down, easy tilting options to make cleaning the windows so easy, locking mechanisms, etc. The ordering process was easy, and staff were friendly."

"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!!!!"
