I want to compliment David on his very professional work on our windows yesterday. He explained the process, and was efficient and effective. He was very pleasant to work with. David discovered a crack in one glass pane and I am grateful he brought it to our attention. The house is new and many items are still under warranty. I was able to contact the window company and get a replacement ordered. I appreciate his diligence and would recommend him and your company highly in the future.
