Why MI?

We’re So Much More Than Windows

As one of the nation’s largest suppliers of high-quality windows and doors for remodeling, replacement, and new construction projects, our customers count on us to provide a proven product backed by exemplary service.

There’s so much that goes on behind our windows to ensure a positive experience for homeowners, our professional partners, and our team members – from the relationships we build, to our relentless attention to detail and state-of-the-art facilities.

Proudly Made In The USA

MI Windows and Doors, LLC (MI) proudly manufactures its windows and doors in plants located across the USA, employing thousands of hardworking Americans to assemble millions of products annually. We use only high-quality components in the manufacture of our windows and doors, and all or virtually all the components used within our vinyl windows and doors originate in the USA.

At MI, we love being a part of building America, whether it’s manufacturing products used in the building of homes and office buildings, or building the local economies of the regions in which we’re located. This is the vision our founders had for the company from the beginning. It’s the vision we’re seeing through to this day.
