D & W Windows & Sunrooms is a family owned and operated business established in 1955. We manufacture all of the windows & sunrooms that we sell. This is done to ensure the highest quality at the lowest price and to truly cut out any middleman. D & W operates out of our state of the art 65,000 sq ft facility located on I-69 in Davison, MI. D & W Windows & Sunrooms has always been recognized both locally and nationally as progressive innovators and leaders within our industry. One example of this is our Super Room sunroom. It’s the world’s first all vinyl and wood composite sunroom with no exposed fasteners. It’s been so well received that we not only sell it in our local market but we currently distribute it in 16 states through our network of dealers. D & W distributes the Super Room® through Crown Sunrooms, our wholesale division. Both companies are members in good standing with the National Sunroom Association (NSA).
