I have had AWP Advanced Window Products install new windows for me on two separate occasions. This last time, it was for the upstairs. They are very professional people, and friendly, and easy to work with. I have noticed a reduction in my electrical usage, but I can not say for sure if that is the windows, or just the effects of the weather. Their prices seem to be reasonable, and about the same as the first time I used them. When I checked prices then, they were very competitive, and I did not even bother checking this last time. Overall, I have been very satisfied with them!
