We have replaced all 16 windows in our home. We have also requested that the patio door and 3 outside doors also be replaced, but since they were not ready at the same time as the windows (some sort of production issue) Beverley Hills offered to do 2 separate installations if we wanted. They do weekend installations, a bonus for those of us that work outside the home throughout the week! I found the installers were friendly, and took good care of our home. They cleaned up after themselves, and took away all the old windows. When we noticed little things (and sometimes big things), there was no discussion, and it was fixed right away. For instance, we noticed that 1 window didn't look like it was leveled properly, we mentioned it on day 2 and it was removed and re-done. We were very impressed with the service of the installers.
