MI Windows and Doors strives to manufacture “Best in Class” windows, doors, and related products used in residential new construction and replacement projects. Since 1947, we’ve focused on great people making great products. To us, “Seeing You Through” is a philosophy that goes beyond the manufacturing facility, beyond the warehouse, and right into each home and construction site. It’s what drives us to manufacture products that are complete, accurate, and delivered on time. But most of all, it’s why our customers place their trust in us.
