Crown Windows & Sunrooms is a family owned and operated business established in 1955. We manufacture all of the windows and sunrooms that we sell. This is done to ensure the highest quality at the lowest price and to truly cut out any middleman. Crown operates out of our state-of-the-art 65,000 square-foot facility located in Davison, Michigan.

Crown Windows & Sunrooms has always been recognized both locally and nationally as a progressive innovator and leader within the industry. One example of this is our SuperRoom® sunroom. It's the world's first and only 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 for over 14 years, we have distributed it ithroughout the country.

Crown Windows & Sunrooms is a proud member of the Earthwise Group. This is a group of local and regional window manufacturers that hold themselves to a higher standard of manufacturing processes.
