We went to Mr. window after bad experiences with two competitors. All I can say is I wished I had found them first, We had to replace a sliding glass door. Sounds simple right? After lousy service, inaccurate information and rude people coming to our house from the competition, at Mr. window we experienced extremely well informed and knowledgeable sales people, and the people who visited our home to measure and then install were professional, friendly and did quick, top notch work. After experiencing none of this from other«competitors» it appears the people at Mr. window are in a class by themselves in this industry!
