A replacement door is only as good as the parts behind it. We stick with established brands known for strong construction and steady performance. That means a door and operator that can handle the pace of a working building.
Clopay makes sturdy steel and insulated sectional doors built for demanding schedules, with clean styling that suits shops, warehouses, and storefronts.
LiftMaster operators bring reliable lifting power and dependable safety features to high-use commercial openings.
Whether you need a new door, a quick fix, or steady upkeep, these are the commercial services we provide across St. Louis.
We pull out the old door and install a new one sized to your opening, with the track and hardware checked or upgraded.
Opening a new building or adding a bay? We install sectional doors and operators from first measurement to final test.
We diagnose and fix springs, cables, rollers, and tracks when a repair makes more sense than a new door.

Overhead garage door replacement means removing a worn sectional door and fitting a new one on the existing tracks, or on new tracks if the old ones are bent or rusted. It’s common at warehouses, auto shops, and service bays where doors take a beating every day. Most jobs include new panels, rollers, and hinges, plus spring and cable checks and operator setup.
As a local commercial garage door company, we handle commercial overhead door replacement from teardown to final test. We confirm headroom, match the spring cycle rating to your usage, and verify every safety sensor. One team takes care of the door, the opener, and what comes after.
Repair works until it doesn’t. When a door needs frequent service, shows structural damage, or no longer fits your equipment, a new one often saves money and stress. Replacing it also lets you upgrade to insulated panels, tighter seals, and a stronger operator.
A correct fit keeps your building secure and your schedule on track. We check the framing, set the tracks level, and tune the springs so the door moves evenly. That attention up front means fewer surprises once the door is in daily use.
