Windows USA did a professional job. They did what they said they were going to do.
I ordered the windows for my bay window and they brought one window too short. Other than that, they did a great job installing. One of my windows was shorter than the other two for my bay window. Another complaint that I wasn't expecting was all of the windows they took out, had a clear color screen on them. This one has a dark color screen on them and I can't see. It is harder to see my ornaments and what-nots, because of the black screen. Those were the only two things that bothered me. Other than that, they did a good job. The installers did a great job installing, and I can tell as difference in my air conditioner running to keep the house cool.
The work was done quickly and very nicely.
From the demonstration, to the actual process of putting the windows in, everything went smoothly. They were kind, respectful, and I had a very good experience.
