MI Windows

MI Windows and Doors is one of the nation’s largest suppliers of vinyl, aluminum and composite windows and doors. With plants across the country, MI offers a broad spectrum of windows and patio doors-backed by exemplary customer service.

The company that now manufactures on a nationwide level began with J.T. Walker and Robert J. Word in 1947 at a Florida airplane hangar making screens. These hardworking, visionary founders never forgot the value of good people as the company continued to expand.

Steadily increasing the scope of its business while adding plants from coast to coast, MI began manufacturing storm windows in 1972, storm doors in 1974, then introduced vinyl replacement windows in 1981. In the 1990s, MI brought its hard work and expertise to the new construction market, purchasing Capitol in the early part of the decade and BetterBilt in 1999.

Having kept the focus on people as its greatest asset, MI continues to manufacture quality windows and doors under our respected brand. Our products serve distributors, architects, builders, remodelers and homeowners alike.

At MI Windows and Doors, you can expect us to continue improving. But we promise that our commitment to Seeing You Through will always remain the same.
