We had a great experience with Next-Gen. Categories: Shortly after moving in, we decided that we needed to replace most of the windows in our home as well as the patio door. They did a good job of explaining our options and we were able to make an educated decision about which windows to go with. The installers were professional and the new windows and patio door look great. Their prices are fair for the quality of windows (and doors) that you get. Definitely give them a call if you’re looking to replace your windows!
