Maintenance is a different job from repair
A repair call starts with a broken door and a stopped bay. A maintenance conversation starts with a list of doors and a budget, and it's often a different person doing the buying.
That matters because the scope and authorization differ. A preventive maintenance proposal should identify the openings, visit frequency, included work and report. A repair proposal should identify the assessment and how corrective work is approved. Mixing them up is how people end up surprised by an invoice.
If something at your facility is out of service right now, say so on the call. Nobody should wait for the next scheduled visit to deal with a door that's stuck open.
What a PM visit should actually cover
Here's the useful part: what to ask a provider to put in the scope, per equipment type. This is a buyer's comparison tool, not a checklist for your own crew.
| Equipment | What a visit should look at | Why it matters | What to ask for in writing |
|---|---|---|---|
| Sectional commercial doors | Panels, hinges, rollers, track alignment and fasteners, bottom seal, hardware torque, general door balance | Small alignment problems are what wreck rollers, tracks and panels | Which doors by number, and what "inspected" means for each |
| Counterbalance systems | Spring condition and cycle use, cable condition and seating, drums, shaft and bearings | These are the parts that fail suddenly and expensively | Findings recorded per door, with observed wear and recommended corrective work recorded |
| Operators and drives | Drive, gearing, limits, chain or belt condition, mounting | An operator running rough is an early warning | Whether operator work is in the visit price or quoted separately |
| Safety devices | Photo eyes, edge sensors, monitored entrapment devices, alignment and function | Confirm the specified protective devices work as intended | That sensor function is tested and the result is documented |
| Rolling steel doors | Curtain and slats, endlocks, guides, bottom bar, hood, counterbalance tension | Different machine, different checklist | That coiling doors get their own scope, not the sectional one |
| High-speed doors | Controller, activation devices, guides, curtain condition, breakaway function | Model-specific; generic scopes miss things | That the provider names the models it's covering |
How often, and what "cycle life" actually means
Frequency should follow the manufacturer’s calendar and cycle-based instructions, adjusted for use and conditions. For example, Clopay’s commercial guidance calls for inspection quarterly or every 5,000 cycles; that example is not a universal interval for every door.
A cycle is one full open-and-close. A component’s specified cycle rating is a design/service-selection figure, not a countdown to an exact failure date. A single-shift workshop and a three-shift distribution bay can accumulate use at different rates, while corrosion, damage and condition also matter.
That is why the maintenance proposal should distinguish your busiest openings from lightly used ones. It should also identify conditions that need attention before the next routine visit.
What to do with that: ask for the applicable manufacturer instructions, the installed equipment’s duty ratings and a schedule suited to its use. Existing cycle records help, but you do not need to calculate a remaining spring life before calling.
Safety device testing
Make safety-device testing an explicit part of the scope, with the installed operator and manufacturer instructions identified. A door that moves is not proof that every protective function works.
DASMA’s guidance explains that commercial vehicular operators manufactured after August 2010 must use a constant-pressure-only arrangement or monitored external entrapment protection as applicable to their design. External devices can include compatible edge sensors, photoelectric sensors or light curtains. Have the provider identify the installed configuration and its requirements; do not turn a sensor fault into a reason to defeat protection.
DASMA and operator manufacturers direct facility owners to conduct regular testing, including monthly testing of photoelectric sensors, following the operator manufacturer's instructions. (DASMA Technical Data Sheet 382, checked 18 September 2026.)
Practically: put sensor testing in the scope, require the operator manufacturer’s instructions, and ask the provider to document the result. Do not ask an untrained employee to approach or test a door that is already damaged or malfunctioning.
You know what belongs in the scope.
Dock equipment maintenance is a separate conversation
A dock is not a garage door. List dock equipment separately in any combined maintenance proposal.
Levelers, seals, shelters, bumpers, restraints and dock lights need their own equipment-specific scope. Ask whether they can be assessed in the same programme, rather than assuming all of them are included. See the planned service sections on dock leveler repair, dock equipment repair and trailer and vehicle restraint repair.
You can absolutely ask for both in one programme. Just make sure the scope names both, rather than assuming "door maintenance" covers the leveler under it. In California there's an extra reason to be explicit — see the licence note below.
Fire doors are a separate, scheduled obligation
Rolling fire-door inspection and testing needs an explicit scope, appropriate qualifications and documentation; it can be contracted alongside maintenance without being silently assumed inside it. DASMA describes annual inspection and drop testing in its guidance, while the applicable code edition and fire authority determine the requirements for the opening.

What we cover, and what we don't
Covered: planned maintenance for commercial sectional, overhead, garage, bay, drive-in, rolling steel and high-speed doors and their operators, at warehouses, distribution centres, manufacturing plants, cold storage, fleet garages, workshops, commercial self-storage and other commercial buildings.
Not covered, and where to go instead:
- Residential garage doors — a residential garage door company.
- Truck and trailer cargo doors — a trailer service shop.
- Pedestrian storefront entrances, automatic entry doors, glass and hollow-metal walk-through doors with their locks and closers — a storefront or locksmith specialist.
- Boat docks and boat lifts — a marine contractor.
- Parts-only orders — a parts distributor.
- Structural concrete, pit and slab work — a concrete contractor.
What happens when you call
- You call (385) 325-7138 and describe what you want maintained. Facility location, then roughly how many openings and what types.
- Your call may be shared with an independent commercial dock-and-door repair company.
- That company confirms availability, scope, pricing, scheduling and its own contract, work and warranty terms.
Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair. We don't perform maintenance, price contracts or schedule visits.
Example of what that first sentence can sound like: "We've got 24 dock positions in Ontario and no maintenance schedule — I need pricing to put in next year's budget." That is example wording, not a script and not a real job.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Useful on the call — and not required
Number of openings. Door types, roughly. Single, double or triple shift. Powered or manual. Age, if you know it. Whether any doors are labelled fire doors. Whether you want dock equipment in the same scope. Whether anything is currently broken.
You do not need any of it. "We have about twenty commercial doors in Ontario and no PM programme" is a complete first call.
What drives the price
We can't quote a maintenance programme from a web page. The price depends on the doors, the visit scope, and how often. Here's what to ask before you sign anything.
| Cost driver | Why it moves the number |
|---|---|
| Number of openings | Ask whether the price is per opening, per visit or per programme |
| Door types and mix | Sectional, rolling and high-speed doors need different scopes |
| Visit frequency | Quarterly and annual are very different commitments |
| What's included versus quoted separately | Agree which findings need a separate repair authorization |
| Parts and consumables | Rollers, seals and hardware — in the price, or extra? |
| After-hours or non-production access | Ask whether the proposed access window changes the rate |
| Multi-site coverage | Several Inland Empire buildings under one agreement changes the maths |
| Reporting and documentation | A report per door per visit takes time and is worth paying for |
Ask which kind of number you're being given — a per-door rate, a per-visit price, a scoped annual contract, or an estimate. And get the exclusion list in writing, not just the inclusion list.
One honest note on what maintenance does. It creates a planned opportunity to find wear and address documented problems. It cannot predict every spring failure or eliminate breakdowns. Ask what gets recorded and how urgent findings are handled between scheduled visits.
You know what to ask now.
What if maintenance finds a repair or replacement need?
Ask for the finding by door number, the proposed corrective work and whether the door must remain out of use. Compare repair with replacement when damage, unsupported parts or a changed duty requirement makes restoration uncertain; a maintenance contract is not automatic permission to replace equipment. The installation and replacement page sets out that separate buying scope.
Local rules that touch a maintenance programme
The licence — and why a combined scope needs a question. CSLB D-28 — Doors, Gates and Activating Devices covers commercial and industrial doors. CSLB D-21 — Machinery and Pumps is the classification whose scope names dock levelers. So if you want doors and dock equipment in one programme, it's worth asking which classifications the company holds. Check it: CSLB licence lookup.
Electrical work found during a maintenance visit may be a separate trade — C-10 territory. Ask how that gets handled and authorized.
A maintenance label doesn't cover everything. If a visit turns into replacing an assembly or putting in a new powered operator, that may become a permit conversation. See the permit routing on the Ontario hub page.
We don't decide what applies to your doors. We give you the rule, where to check it, and the question; the provider and the issuing office confirm it.
Where we take these calls
Ontario and the surrounding Inland Empire, across San Bernardino and Riverside Counties. Multi-site programmes across several buildings are a normal ask. The independent provider confirms each facility address and its own availability. Full service area →
Maintenance questions
How often should commercial doors be serviced?
Follow the installed equipment manufacturer’s calendar and cycle-based instructions, taking usage and conditions into account. Clopay’s commercial guidance, for example, specifies inspection quarterly or every 5,000 cycles; other equipment has its own instructions. Ask the provider to name the instruction and interval used for each door family.
Can one contract cover doors and dock equipment?
Ask the provider whether it can offer both, then name the doors and each dock-equipment family explicitly in the scope. Do not assume “door maintenance” includes the leveler. Also ask which CSLB classifications cover the proposed work, since D-28 lists doors and D-21 names dock levelers.
Does a PM contract include parts?
Sometimes, up to a value; sometimes not at all. That distinction belongs in the written scope. Get the inclusion and exclusion list in writing, and ask specifically how corrective repairs found during a visit get quoted and authorized.
Do our safety sensors need testing even if the door works fine?
Yes. DASMA’s guidance calls for monthly testing of photoelectric sensors following the operator manufacturer’s instructions. Ask who is qualified to perform the checks and how results are recorded; apparent normal door movement is not a substitute for those checks.
