I choose Beverly Windows primarily for there warranty. I had them install my windows twice, since windows are very costly. The first time, the installation was a joke. The installer was a short man so I had to assist in the installation and use my tools. I had to later call my and had a service man repair there work (there repair service calls are excellent., this a major plus and the choice I choose Beverly windows)
The second installation a couple of years later was great, although they missed measured the window and had to return a few days later. (this wasn't an issue to us because mistakes happens). A couple of years past and we had a baby and began using this room. Last year, I found the room very cold during the winter (colder then the older windows) and didn't know why? Two weeks ago I pulled out the trim, and shocked to find missing spry insulation on the top and bottom of the window. Once I insulated the windows the room is toasty and no long drafty
In summary, I would rate the windows and service calls excellent, but the installation was horrable. I choose a competitor company to finish my other windows. This time I watched every installation.
