D&W Windows and Sunrooms

D&W Windows and Sunrooms has made the windows and sunrooms it sells in Michigan since 1955, manufacturing them at its own facility in Davison. Its signature product is the Super Room, a sunroom built from vinyl and wood composite with no exposed fasteners, which the company also distributes to dealers in 16 states through its Crown Sunrooms division. The company also sells roofing, siding, patio and entry doors, patio covers, retractable awnings and bath remodeling.

Estimates are free and include in-home visits. Showrooms are in Auburn Hills and Saginaw, and there is a showroom in Davison as well. The company is locally owned and is the only Earthwise Group window manufacturer in Michigan, with windows designed for the state's weather extremes.
