Preventive Maintenance
The program that converts emergencies into scheduled visits.

| Failure | Typical Cause | Downtime Character |
|---|---|---|
| Broken torsion spring | Cycle exhaustion — usually undersized for actual usage | Door dead until replaced; priority repair |
| Forklift / truck impact | The eternal classic | Slat or panel replacement, track repair, alignment |
| Operator failure | Duty-cycle overload, worn drive, control faults, heat | Manual chain-hoist operation possible on many doors meanwhile |
| Bent / spread track | Impact or fastener fatigue under vibration | Door jams or runs rough; escalates fast if ignored |
| Cable / drum damage | Fraying, misalignment, spring events | Door racked or dropped on one side — stop using immediately |
| Worn rollers, hinges, bearings | Dust + heat + cycles | The noisy prelude to bigger failures |
| Photo eyes / sensing edge faults | Impacts, wiring, sun-blinding | Door won't close — security exposure |
How Commercial Repair Runs
- Triage on the phone
Door type, failure, impact. If a photo can save a trip or pre-load parts, we'll ask for one.
- Stabilize and secure
First priority on site: make the opening safe and, where possible, operable — even temporarily — so business continues.
- Written quote to your process
Itemized quotes for approval workflows; work proceeds on your sign-off.
- Repair, test, document
Repair with commercial-grade parts, full function and safety testing, and documentation of what was done and what's aging for your records.
The pattern behind most emergency calls
Nearly every "sudden" commercial failure announced itself for weeks — noise, slowing, a fraying cable — on a door nobody was assigned to watch. A maintenance program exists to be that assignment.
Common questions
Frequently Asked Questions
What information speeds up a commercial repair call?
Five things: door type (roll-up or sectional), approximate size, what failed and what you observed, the operational impact (blocked dock vs. inconvenience), and access details (site contact, hours, dock restrictions). Photos help enormously — a picture of the failure often lets us load the right parts before rolling.
Why do commercial springs break so much more often than residential?
Cycles. A home door runs maybe 1,500 cycles a year; a busy bay door can do that in a month. Springs are cycle-rated consumables, so a spring correctly sized for a house lasts years while an undersized commercial spring dies in months. Part of our repair is checking whether your springs' cycle rating matches your actual usage — and quoting high-cycle springs when it doesn't.
Can damaged roll-up slats be replaced without a new curtain?
Often, yes — individual slats or slat sections can be replaced when damage is localized (the classic forklift kiss). Widespread curtain damage, seized bearings or a bent barrel changes the math toward larger repair or replacement. We quote what the damage actually requires.
Do you repair dock-area doors and equipment?
We repair the doors and their operators at dock positions — panels, tracks, springs, seals and operators. For dock levelers and vehicle restraints, ask when you call; where it's outside our scope we'll say so plainly rather than improvise.
