The people are very courteous. I felt bad for the installer because it started pouring down rain while installing. I offered them both a cup of coffee to help warm them up.
Window World is wonderful. We have used their services for many years, and I am very satisfied with them. The staff there are amazing: congenial, considerate, helpful, and wonderful. If I call and mention I have an issue, they will send someone to fix it.
It was very fine and they did good work.
