We used Advanced Window Products because a coworker of mine had used them a couple of years ago and had really good luck with them and said they were very professional. We went online, did our research, and everything looked good. We called them up and the estimator came out 30 minutes early. They did everything they said they were going to do, and when they were in the house there was a minimal mess. They cleaned everything up, took care of all the stuff, and they were in and out fast. It was a really good experience. We had just gone through a house remodel and we didn't want it to get messy again. As it turned out, it was not inconvenient at all. Their prices were good- they were probably one of the more reasonably priced places we looked at. We may have found one place that was a little cheaper, but we heard such good things about Advanced Window Products that we went with them because of the ratings. The quality of the products looks good so far and we have no complaints. The salesperson we spoke with delivered great service as our main contact for the project. The installers were also good- clean, fast, and professional. My wife and I are very happy with it, and we have already recommended Advanced Window Products to a couple of friends.
