Improve Your View with D&W: Manufacturing and Installing Residential Windows and Sunrooms since 1955.D&W Windows & Sunrooms is a family-owned and operated business established in 1955. We manufacture all of the quality residential windows and sunrooms that we sell. This is done to ensure consistent quality at the lowest price and to truly cut out any middlemen. D&W operates out of our state-of-the-art 65,000 sq. ft. facility located on I-69 in Davison, MI. We have 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). D&W has been a member of Earthwise since 2005. This is a group of local and regional window manufacturers that hold themselves to a higher standard of manufacturing processes. The Earthwise Group and D&W consistently meet and exceed the rigorous standards set forth by ENERGY STAR. D&W Windows and Sunrooms can proudly say we are the only window manufacturer in Michigan that has earned the Good Housekeeping Seal.
