Where Clopay Appears in Southern California
Clopay is the largest commercial sectional door brand in Southern California. Clopay Corporation's acquisition of CornellCookson and Alpine Overhead Doors, on top of its original commercial sectional line, makes the company the dominant name across door categories in this market — not just sectional.
Clopay commercial sectional doors show up in every county we cover, from light industrial flex space in Brea and Lake Forest to food manufacturing and heavy industrial buildings in San Bernardino and Riverside County. We see them on tilt-up concrete tenant improvements built through the 2000s Inland Empire boom just as often as on older strip-industrial buildings retrofitted with a new door section.
The Clopay 500 and 600 Series steel doors are the most common commercial sectional specification written into Southern California industrial construction from the mid-1990s forward. Most general contractors default to Clopay when a spec sheet just says 'commercial sectional steel door.'
What We Repair on Clopay Equipment
Torsion spring replacement
Clopay commercial doors use torsion springs rated by cycle count and door weight. When a spring snaps, the door won't lift, or the operator strains and trips its overload.
We match spring wire size, length, and wind direction to the original Clopay spec rather than installing a generic spring that shortens cycle life. This is the single most common Clopay call we run.
Panel and section replacement
Forklift strikes and truck impacts dent or crack steel sections, especially on the bottom two panels near dock doors.
We source matching Clopay 500, 600, or 700 Series panel profiles and color, then swap the damaged section without pulling the whole door out of service.
Track, roller, and hinge service
Galvanized track walls get bent from forklift contact, and steel rollers wear flat spots that make the door bind or jump the track.
We straighten or replace track sections and swap worn rollers and hinges for sealed nylon rollers where cycle counts justify the upgrade.
Operator and safety reversing
Chain hoist and jackshaft operators on Clopay doors lose calibration over time, causing the door to reverse early or fail to reverse on contact.
We recalibrate limit switches and test photo-eye and edge sensor reversing to current safety standards before signing off.
Bottom seal and weatherstripping
Astragal and bottom weatherseal on Clopay doors crack and pull loose from UV exposure and repeated dock traffic, letting in dust, rodents, and outside air.
We replace the seal to the correct Clopay track profile so it seats flush against the slab.

We Repair Clopay — And Every Other Brand in Your Facility
InSev Tech services every major commercial sectional door brand across Southern California. Clopay is the brand we see most often in light industrial and distribution buildings, but the same facility might also run Wayne Dalton, Amarr, or C.H.I. doors depending on when a section was replaced or which contractor built which phase.
One service call covers whatever is on your building. We don't specialize in one brand at the expense of fixing what's actually installed.
