Common commercial door problems
| Problem | Usual cause |
|---|---|
| Door won’t open or is very heavy | Broken spring or a spring that lost tension |
| Door rolls unevenly or jams | Bent slats, worn guides, a dented bottom bar |
| Motor runs, door doesn’t move | Drive chain, brake or clutch problem |
| Door reverses or stops | Sensor or edge switch fault |
| Gaps and drafts | Worn bottom astragal or weather seals |
Fire door inspections
NFPA 80 requires fire door assemblies to be inspected and tested at least annually by a qualified person, with records kept. For rolling steel fire doors, that includes a drop test to confirm the door closes fully on its own. If a fire marshal or insurer has flagged your doors, mention it when you call.
Why commercial doors wear faster
A busy warehouse door can cycle more times in a week than a home door does in months. Springs are rated in cycles, so high-traffic doors need high-cycle springs and more frequent inspection. Salt air near the waterfront industrial areas speeds up rust on slats and guides.

Frequently asked questions
Do you repair roll-up doors?
Yes. Coiling steel doors on storefronts, warehouses and storage units, including springs, slats, guides, bottom bars and motors.
Do commercial fire doors need annual inspection?
Yes. NFPA 80 requires fire door assemblies, including rolling steel fire doors, to be inspected and tested at least once a year, with a written record kept. Your fire marshal or insurer may ask for it.
Can you fix a door that's stuck open overnight at a business?
Call and say it's a security issue. Stuck-open commercial doors are treated as urgent.
Do you service loading-dock doors?
Yes, sectional dock doors, their springs, tracks and operators, and dock seals.
Can you set up a maintenance schedule?
Yes. High-cycle commercial doors wear springs and cables faster than home doors. A scheduled inspection catches worn parts before a failure stops deliveries.
