A 12-point quarterly checklist that prevents 80% of the unplanned downtime we see at warehouses, body shops, and fleet bays in the Tri-State.
When a commercial overhead door fails, the cost isn't the repair — it's the 4 hours of stopped production behind it. This 12-point quarterly checklist is the same one our techs run during PM contract visits across Evansville, Newburgh, and Henderson.
The 12-point quarterly checklist
- Visual inspection of all panels for impact damage, rust, or delamination.
- Spring inspection — check for gaps, rust, and remaining cycle life.
- Cable inspection — look for fraying near the bottom brackets.
- Roller inspection and lubrication (lithium grease, NOT WD-40).
- Track alignment and bolt-torque check.
- Hinge inspection and lubrication.
- Bottom seal (astragal) check for tears and gaps that let in cold air / pests.
- Photo-eye sensor alignment and cleanliness.
- Opener motor — listen for unusual noise, check chain/belt tension.
- Limit switch settings — door fully closes and fully opens.
- Force-reverse safety test (place a 2x4 in the path; door must reverse).
- Operator electrical connections and surge protection check.
Industry-specific items to add
- Fleet bays — additional cycle-count check, since cycle life dictates spring replacement timing.
- Body shops — check for paint overspray on photo eyes (#1 false-trip cause).
- Distribution centers — dock leveler and weather-seal inspection alongside the door.
- Fire stations — full opener-failure drill and battery-backup discharge test.
- Cold storage — gasket inspection and ice buildup check at bottom seal.

What's the cost of a commercial garage door maintenance contract?
Pricing scales by number of doors and cycle volume. Most Evansville-area contracts run a flat quarterly per-door fee with priority emergency response included. We provide written quotes after a free site walkthrough.
