Every facility runs some mix of planned and unplanned maintenance. The question is the ratio — and how deliberately it was chosen. With industrial doors and loading dock equipment, where a single failure can stop receiving or shipping for a whole shift, the difference between the two approaches is rarely subtle.
What Reactive Repair Looks Like
Reactive — or "run to failure" — means equipment is serviced only when something stops working. There is no scheduled inspection, no lubrication interval, no documentation of wear trends. When the door jams, the dock leveler won't lower, or the curtain tears, a service call goes out.
The appeal is straightforward: no PM line item in the budget, no scheduled disruption to operations. The cost shows up elsewhere — emergency dispatch fees, after-hours premiums, expedited parts, longer downtime while a technician diagnoses an unfamiliar door, and the operational chaos described in our cost-of-downtime framework.
What Planned Preventive Maintenance Looks Like
A PM program involves scheduled inspections at intervals tied to door type, cycle count, and criticality. Each visit follows a standard checklist (see our maintenance checklist), produces a written report, and surfaces wear before it becomes failure. Springs, cables, rollers, seals, and brakes are replaced on a wear-based schedule rather than after they have already caused a stoppage.
Modern PM programs also build an asset history. Over a few cycles of service, the facility has documented data on each opening: failure modes, parts consumed, cycle counts where logged, and remaining life on major components.
How the Two Models Compare
Predictability of spend
PM produces a predictable, budgetable annual cost. Reactive spend is lumpy — quiet for months, then a large unplanned hit that often does not fit the budget cycle it lands in.
Operational disruption
PM disruption is scheduled and short. Reactive disruption is unscheduled and tends to land at the worst possible moment, since failures correlate with high usage.
Asset life
Doors and dock equipment have meaningful wear items — springs, cables, seals, motors, brakes, gearboxes. Replaced on a wear basis, they protect the larger assemblies. Run to failure, a single worn component often takes others with it (a broken cable damaging panels, a worn brake destroying a gearbox).
Safety and compliance posture
Fire-rated doors, vehicle restraints, and accessibility-related doors all have inspection or testing expectations. PM creates the documentation. Reactive programs typically have no documentation, which becomes a real problem during an audit, insurance review, or post-incident investigation.
Vendor familiarity
A service provider on a PM program knows the equipment, the site, the access constraints, and the people. The first ten minutes of an emergency call are not spent finding the door, the disconnect, and the spare key.
How Facilities Actually Decide
In practice, the decision rarely lands all the way at one end or the other. Most operations end up with:
- Planned PM on high-cycle, safety-rated, and revenue-critical openings — main dock doors, fire-rated assemblies, cold-storage and high-speed doors.
- Inspection-only intervals on lower-cycle openings.
- Reactive service for genuinely low-risk doors where failure has no meaningful operational or safety consequence.
The honest comparison is not "do we spend on PM or not?" — it is "where on this spectrum do we sit, and is that placement deliberate?"
Related Decisions
For aging equipment, PM eventually runs into a different question: at what point does another repair stop making sense? That is covered in our repair-or-replace decision framework. For multi-site operators, standardizing the PM model across locations is its own challenge — see managing maintenance across multiple facilities.
