Our Story

For over 25 years, Superior Door Inc. has been the Bay Area's trusted name in commercial roll-up door installation, maintenance, and repair. Family-owned and operated, we've built our reputation one door at a time — delivering reliable service, honest pricing, and the kind of accountability that only comes from a business where the family name is on the line.

​

We specialize in commercial-grade roll-up doors, dock levelers, and door operating systems for warehouses, distribution centers, industrial facilities, and commercial properties of all sizes. From new construction installs to scheduled service and preventative maintenance, our experienced technicians bring precision and professionalism to every job — whether it's a single bay door or a multi-site rollout across a major portfolio.

​

Based in Fremont, CA, we proudly serve clients throughout the greater Bay Area, including property managers, general contractors, and facility operations teams who depend on us to keep their buildings running safely and efficiently. Our long-standing relationships with leading commercial property firms speak to the trust we've earned — and continue to earn — every day.

At Superior Door, we don't just service doors. We build lasting partnerships with the clients who count on us to show up, do the work right, and stand behind it.
