For a business, an overhead door that won’t open means stalled deliveries, idle staff and a building that isn’t secure. Commercial doors also cycle far more often than residential ones, so they wear faster. A simple maintenance routine helps prevent breakdowns and catches safety issues early. Here’s the checklist we recommend to commercial clients across York Region.

Monthly checks your team can do

  • Watch and listen to a full cycle. The door should move smoothly without jerking, grinding or banging.
  • Test the safety reversal. Pass an object through the photo-eye beam while the door is closing. It should stop and reverse. Check any edge sensors too.
  • Look at the bottom seal and weather stripping. Torn seals let in cold air, water and pests.
  • Check for impact damage. Dented sections, bent tracks and damaged guards are common in busy loading areas.
  • Keep the tracks clear. Remove debris, ice and anything stored too close to the door path.
  • Make sure controls are labelled and working, including any emergency stop.

Professional maintenance items

These jobs involve high spring tension and heavy components, so they should be done by a trained technician:

  1. Springs and cables: inspect for rust, gaps and fraying, and check spring tension and door balance.
  2. Rollers, hinges and bearings: check for wear and lubricate.
  3. Tracks: check alignment and fastening.
  4. Operator: check limits, force settings, drive components and brakes.
  5. Fasteners: tighten loose bolts on hinges, brackets and the operator mount.
  6. Rolling doors and grilles: check the barrel, curtain slats and guides.
  7. Safety devices: confirm sensors, edges and labels are in place and working.

How often?

Doors that cycle many times a day, such as loading docks, service bays and fire halls, benefit from more frequent professional service than a door that opens a few times a week. A technician can recommend a schedule based on how heavily each door is used.

Signs you need service now

  • The door is very heavy to lift manually, or drops when released partway.
  • A loud bang from the spring area.
  • Cables are loose, frayed or off the drums.
  • The door opens unevenly or binds in the tracks.
  • The operator runs but the door doesn’t move, or it reverses for no reason.

Don’t keep running a door with these symptoms. It can cause further damage or injury.

When repair isn’t enough

If a door is being repaired constantly, an upgrade may cost less in the long run. Options include insulated sectional doors, full-view aluminum doors for showrooms and service bays, high-lift tracks for tall equipment, and rolling security grilles. We’ve installed doors as large as 30 feet wide by 20 feet high, such as the Upwardor doors at Technicore.
