Ken H was a pleasure to work with as he looked at our windows, educated us on Feldco, and came up with a plan for our window replacements. We felt very comfortable talking with him in our home and felt like we could trust him to deliver great results on our window project. We had four quotes for windows and feldco by far had the best sales experience as they were thoughtful, knowledgeable, and brought an actual window for us to touch/feel/see.
