Is this a maintenance call or a repair call?
Preventive maintenance (PM) is planned upkeep; repair is for something already broken. Sort that out before you pick up the phone so the quote covers the right job.
Maintenance is planned. Somebody comes on a schedule, works through a checklist on doors that are currently working, and tells you what is heading for trouble. Repair is something already broken, and it gets priced differently.
If a door is down right now, start here instead: commercial overhead door repair, roll-up and rolling steel door repair, dock leveler repair or high-speed door repair.
How often should commercial doors be serviced?
The interval follows the door manufacturer's recommendations, the door type and how hard the bay runs. Rolling-door guidance gives a useful starting point; it is not a universal schedule for every commercial door.
For rolling doors, DASMA is specific. A trained door systems technician should perform periodic inspection and maintenance "at least annually or per the door manufacturer's recommendations." The performance of electric doors should be evaluated quarterly. And an event such as high wind, seismic activity or flooding "should require an immediate evaluation of all door systems in the facility regardless of when the last periodic inspection was performed" (DASMA TDS #270).
For commercial sectional doors, use the door manufacturer's maintenance instructions. Do not borrow the rolling-door number and present it as a sectional standard. The interval also has to account for how hard the bay is actually worked. A bay that cycles forty times a day is not on the same schedule as one that opens twice a week, and any provider worth using will ask about cycles before proposing a frequency.
What does an interval actually cover?
A commercial door maintenance visit works through the applicable door, operator and safety-device checklist. Agree the actual checklist and any separately quoted repairs with the provider; the table below is a scope to discuss.
| Item | What gets looked at | Why it is on the list | What it does not cover |
|---|---|---|---|
| Counterbalance and springs | Tension, condition, signs of fatigue | This system counterbalances the door's weight | Replacing a spring set — that is a repair |
| Cables and drums | Wear, fraying, seating | Fraying and wear can reveal damage before a cable parts | Cable replacement |
| Tracks, rollers and hinges | Alignment, wear, fixings | Damage here can cause binding | Straightening an impacted track |
| Panels, slats and bottom bar | Damage, squareness, seal at the floor | Small impacts accumulate | Panel or slat replacement |
| Operator and drive | Function, limits, mounting, noise | Changes in noise or travel need assessment | A new operator |
| Entrapment protection devices | That they are present, aligned and functioning | DASMA distinguishes constant-pressure-to-close-only operation from operation using monitored external protection; the technician checks the approved setup (TDS #382) | Adding a device that was never fitted |
| Controls and limits | Settings, response, condition | Wrong travel limits can strain door components | Control replacement |
| Seals and weather stripping | Condition at the jambs and floor | Cheap to replace, expensive to ignore | Bulk seal replacement across a dock |
| Fasteners and mounting | Tightness, corrosion, structural attachment | Everything hangs off these | Structural repair to the building |
What maintenance is not. The word alone does not promise a parts allowance, breakdown repairs or a warranty. A visit that finds five faults can lead to a separate repair quote — which is fine, as long as you have agreed in advance how that gets handled.
Rated doors are on a separate schedule
If any of your doors are fire-rated, they have their own inspection and testing requirements; a general maintenance checklist does not cover that scope by itself. DASMA TDS #299, discussing NFPA 80-2022 and the 2024 IFC, describes annual inspection and testing of rolling steel fire doors by a trained technician, with records kept. Ask which requirements apply to the assembly and the locally adopted code. See rolling fire door repair, inspection and testing.
Dock equipment maintenance is a different list
Levelers, seals, shelters, bumpers, lights and restraints get their own checklist. They can be done on the same visit, but they are not the same scope, and a quote that says "doors and dock" without splitting them is worth questioning. See dock leveler repair and dock equipment repair.
What happens when you call?
Describe the facility and the maintenance you want to arrange. The request may be shared with an independent provider, which confirms whether it can take the work and on what terms.
- You describe the site. Address, how many doors, roughly what types, how hard they run.
- The request may be shared with an independent commercial dock-and-door repair company that may be able to serve the facility.
- That company confirms eligibility, the scope of a program, availability, pricing, scheduling and its own terms.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
An example of what is enough to say: "We've got eleven bay doors and two fast doors at our facility in San Antonio and want to set up a schedule — I can give you the address." That is example wording, not a real job and not a script.
Useful, but not required: how many doors and what types; roughly how many cycles a day the busiest bay runs; whether anything is currently faulty; whether your operators are older or newer, if you happen to know; and your shift pattern and site access. Call without any of it.
What affects the price?
We can't price a maintenance program from a web page. It depends on how many doors, what type, how hard they run, and access. Here's what to ask before you sign anything:
- What exactly is on the checklist, item by item?
- Who performs it, and what training do they have on these doors, operators and any rated assemblies?
- What happens when something needs a part — is it quoted separately, and at what rate?
- Is there a call-out charge on top of the program, or is it included?
- Does the price change with frequency, and what does each frequency actually cover?
- What record do I get after each visit?
- Who handles permits and trade licensing if the visit leads to replacement or electrical work? See the local replacement and permit questions.
What moves the number: the number and type of doors; cycle demand on the busiest bays; access and shift constraints; how often you want the visit; whether dock equipment is on the same scope; and travel. Ask for the program scope in writing before you agree to a frequency — a maintenance agreement is the one purchase in this trade where the document matters more than the conversation.

Maintenance questions
How often should our bay doors be serviced?
For rolling doors, DASMA says at least annually or per the manufacturer's recommendations, with electric doors evaluated quarterly. For sectional doors, use the manufacturer's maintenance instructions and account for how hard the bay runs. A provider should ask about cycles before proposing a schedule.
Does maintenance include parts?
Only if the agreement includes them. Agree in advance what happens when a part is needed — whether it is quoted separately, at what rate, and whether the technician can proceed up to a set value without calling you.
Our operators are old. Is that a maintenance item or a replacement?
Ask the provider to assess that during the maintenance visit. What a provider looks at is whether the operator still runs within its limits, whether the controls and entrapment protection devices are present and working, and whether parts still exist for it. See installation and replacement.
Do dock levelers go on the same program?
They can be on the same visit, but they are a different checklist. Ask for the dock equipment scope separately so you can see what is actually covered.
