"Brian and Kurt were great. We had our 30 + year old Anderson windows removed and replaced with new glass. This is much less expensive than a full window replacement, and is possible when the basic window frame is still in good condition. Super happy with the result."

"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 We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter!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."

"Mr Atkins was very knowledgeable about the windows that he was selling, very friendly. Mr Atkins was not pushing me to buy the windows which I like. Once again thank you for your professionalism. I look forward to getting my new windows installed! Kelly"

"Window concepts did a great job. The original company that supplies their windows went out of business, so they had to pivot to a new company to fill our order. That put us back about 2 months from our original timeline but very happy with final outcome."
