First they had to come to my home and measure our window size three times then after all of that, the window size was incorrect. We had to wait another two weeks over the six weeks we waited originally. I have to rate the installers at A+ because they were professional and did a great job. Communication was not good and after all the issues we had, we never heard from them to make sure we were satisfied. I would not recommend the company but would recommend the installers!
