What should a maintenance visit cover?
A planned visit checks the parts that wear out before they fail in the middle of a shift. A qualified provider looks at the door, the parts that balance it, the opener and the safety devices. The exact list depends on the door type and how hard it works.
| Door type | What a qualified provider typically checks | Why it matters |
|---|---|---|
| Sectional overhead door | Springs, cables, drums, rollers, hinges, tracks, panels, seals | Worn springs and cables are the usual cause of a door that won't lift |
| Rolling steel door | Curtain, slats, guides, bottom bar, spring barrel, hood | Bent guides and worn slats lead to jams |
| High-speed door | Curtain, breakaway parts, drive, sensors, controls | These doors cycle constantly, so small faults add up |
| Openers and safety devices | Opener, limits, photo eyes, safety edge, controls | Safety devices must stop and reverse the door |
| Dock doors at levelers | Door plus bottom seal, and how it meets the leveler and seal | A dock door that leaks or binds hurts the whole bay |
Fire doors and dock equipment have their own checks:
- Rolling fire doors need yearly drop tests. In the City of Los Angeles, LAFD's Chief's Regulation 4 sets a 1-year cycle (LAFD). See rolling fire doors.
- Levelers, seals, bumpers and restraints are on the leveler, dock equipment and restraint pages.
How often should commercial doors be serviced?
It depends on how hard the doors work. A door that cycles all day needs attention more often than one opened a few times a shift. DASMA, the door and access systems manufacturers' association, recommends testing photo-eye safety sensors every month.
A good way to set the schedule is to sort your doors by use:
| How the door is used | What that means for planning |
|---|---|
| Opens and closes all day (busy dock, main bay) | Put it on the most frequent schedule |
| Opens a few times a shift | A standard schedule usually fits |
| Rarely used, or used for security only | Still check it — doors that sit can stick |
| Rolling fire door | Follows the yearly test cycle set by your fire authority |
| Door that has failed before | Put it near the top of the list |
Ask the provider to suggest a schedule for your door list. More background: commercial garage door maintenance checklist.
Have a rough door count? That's enough to start the conversation.
Things your team can watch for
Your team doesn't need to touch the mechanism to help. Watch and listen from a safe distance, and write down what you notice:
- New noises: grinding, banging, squealing.
- A door that moves slower than it used to, or jerks.
- A door that reverses or won't close all the way.
- Visible damage: dents, bent tracks or guides, frayed cables.
- Torn bottom seals or weatherstrips.
- Light or air coming in around a closed door.
Report these when you call. Don't adjust springs, cables, tracks or openers, and don't lubricate or tighten parts on your own — maintenance is the provider's job.
How the call works
- Call (385) 325-7138. Say how many doors, what types if you know, and the facility address.
- Company confirms the job. If the request is shared with an independent commercial door company, it confirms whether it can take on the work, the scope, the price and its own terms.
- You decide. Nothing is approved until you agree to it.
Example of what to say: "We have 14 dock doors at our warehouse in Santa Fe Springs and want to set up regular maintenance." That's example wording — say it your way.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

What does commercial door maintenance cost?
We can't quote a maintenance plan from a web page. The price depends on the number and type of doors, how often they're checked, and access. Here's what to ask before you agree to a plan.
| What moves the price | Why | Ask the company |
|---|---|---|
| Number of doors | More doors, more time | "Is it priced per door or per visit?" |
| Door types | High-speed and fire doors take longer than a simple sectional door | "Does the price change by door type?" |
| How often | Monthly, quarterly and yearly plans cost differently | "What schedule do you suggest, and why?" |
| What's included | Some plans include small parts; many don't | "Are parts and adjustments included, or billed separately?" |
| Repairs found | Worn parts found on a visit are usually quoted separately | "Will you get my approval before any repair?" |
| Access and timing | Working around a busy dock or off-shift can change the price | "Is off-shift work priced differently?" |
Get the plan in writing: what's checked, how often, what's included, and how repairs get approved.
Ask how a plan for your doors would be priced when you call.
Maintenance vs. repair
Maintenance is planned. It's scheduled checks and small adjustments to keep doors running. Repair is fixing something that already broke. A maintenance visit often finds parts that need repair soon — those should be quoted separately so you can decide.
If a door is broken right now, go to commercial overhead door repair or roll-up door repair.

Frequently asked questions
How often should commercial doors be serviced?
It depends on how hard they work. Busy doors need more frequent visits than doors used a few times a shift. DASMA recommends testing photo-eye sensors monthly. Ask the provider to suggest a schedule for your door list.
Does maintenance include fire door testing?
Not always. Fire-door drop tests have their own rules and, in the City of Los Angeles, a certified tester under LAFD's Chief's Regulation 4. Ask whether a plan includes them.
Can maintenance be scheduled outside receiving hours?
Ask the company. It confirms its own availability and whether off-shift work is priced differently.
What's the difference between maintenance and repair?
Maintenance is planned checks and adjustments. Repair fixes something that already broke. Repairs found during maintenance should be quoted separately so you can decide.
