Is this the door you mean?
A sectional commercial garage or overhead door is built from horizontal panels that travel in tracks, overhead or up the wall. If yours is one curtain of interlocking slats that coils onto a barrel above the opening, that is a rolling steel or roll-up door — a different mechanism with different parts. If its label or building records identify a fire rating, it is a rated assembly with its own rules. Mention any closure during a fire alarm, too.
Two words cause most of the confusion. Dock door describes where a door is used. Sectional overhead describes how it moves. A sectional overhead door can serve a loading dock, a drive-in opening or a service bay. Whether the dock equipment under it is also broken is a separate question.
| What it looks like | What it is called | What you would notice when it fails | Where to go |
|---|---|---|---|
| Horizontal panels running up a track | Sectional door, overhead door, bay door | Off track, bent panel, broken spring, dead operator | This page |
| One curtain of interlocking slats on a barrel | Rolling steel, roll-up, coiling door | Curtain binds, slats bent, out of the guides | Roll-up and rolling steel door repair |
| Thin corrugated curtain | Rolling sheet door | Creased curtain, bent bottom bar | Roll-up and rolling steel door repair |
| Fabric or rigid door that opens fast | High-speed, rapid-roll door | Torn curtain, lost position, crash stop | High-speed door repair |
| Fire-rated rolling door identified by its label or records | Rolling fire door, fire shutter | Dropped and will not reset | Rolling fire door repair |
| A platform set into the dock floor | Dock leveler | Will not raise, lip will not extend | Dock leveler repair |
What should you report when a commercial door will not open or close?
Describe what the door is doing. That is enough. A symptom on its own does not establish which part failed, so nobody should be naming the broken component over the phone — including us.
| What it is doing | What a qualified provider inspects | Why it matters | How to say it |
|---|---|---|---|
| A bang, and now it will not move | Spring and counterbalance condition, cables, whether the door now hangs on the operator alone | A failed counterbalance can leave a heavy door unsupported. Do not use the manual release | "Something banged and now it won't move" |
| Stuck part-way open | Cables and drums, track alignment, operator limits and controls | An open bay is an exposed building | "Bay 4 is stuck about halfway open" |
| Off the track | Rollers, hinges, track, whether a vehicle struck it | A partly retained door can fall | "One of the tracks came off — it's the top one" |
| Panel crushed or shifted after an impact | Panel and strut condition, frame and jamb, whether the opening is still square | Impact damage that looks cosmetic often pushes the whole assembly out of square | "A trailer backed into bay 7 and the left side shifted in about six inches" |
| Will not close, or reverses right at the floor | Photo eyes, edge sensor, monitored entrapment protection, obstruction, operator limits | An obstruction or protection fault can stop travel; never defeat the device | "It goes down a foot and comes straight back up" |
| Operator hums, trips a breaker, or does nothing | Operator, drive, wiring, and whether any of that scope is regulated electrical work | Electrical scope may need a licensed contractor | "The motor hums but the door doesn't move" |
| Drifts down on its own, or slams | Counterbalance adjustment, cable condition | A door that will not hold position is a load overhead | "It won't stay up where we leave it" |
| Noisy, binding, travels unevenly | Rollers, hinges, track, lubrication history | Binding and uneven travel need inspection before further use | "It's been getting louder and it judders on the way up" |
Safety, kept short. We do not give instructions for springs, cables, counterbalance systems or operator wiring, and nothing on this page is a repair procedure. Until someone qualified looks at it: keep people clear of the opening, do not force the door, and take the bay out of use through your facility's normal process. Do not approach the door, reset anything, or try to inspect it yourself.
Could the problem involve the operator or controls?
Often, yes — and it is worth knowing where the door ends and the electrical work begins.
Commercial doors usually run on a jackshaft operator mounted beside the shaft, or a trolley operator on a rail. Around them sit the limits that tell the door where to stop, the photo eyes across the opening, and any edge sensor on the bottom bar.
For operators built after August 2010, DASMA describes two options: constant-pressure-to-close only, or a suitable monitored external entrapment-protection device. The latter can be a contact sensor such as an edge sensor, a non-contact sensor such as a photo eye, or a light curtain. For operators manufactured before 2010, DASMA distinguishes constant-pressure and specified three-button controls from other remote or unattended operation, which needs an external entrapment-protection device. The provider checks the operator's manufacture date, controls and manufacturer instructions; these distinctions are not permission to change or bypass a safety system. (DASMA TDS #382)
A numbering trap worth avoiding. DASMA's Class I through Class IV labels describe vehicular gate operators — residential, commercial, industrial and guarded industrial. A door operator is defined separately, as a vehicular door operator. (DASMA TDS #350) If a quote calls your door operator "Class II," it is worth asking what they mean by it.
On the electrical side. Running a new circuit and disconnect for an operator can cross into regulated electrical work, which, when non-exempt, Texas requires a licensed person working through a licensed electrical contractor to perform (TDLR Electricians). The provider still needs to establish the electrical scope when reusing an existing circuit. Separately, Texas DPS states that installing garage door openers and gate openers needs no DPS license when no other activity regulated by Occupations Code Chapter 1702 is performed, including "operators for gates and residential or commercial garage or upward-acting doors" — but that an operator "connected to an alarm system or that allows for monitoring or logging of ingress/egress does require a license" (Texas DPS). Ask who holds which credential for the part of the job that needs it.
Is this an emergency commercial garage door repair?
If the door is stuck open, or will not close at the end of a shift, say that in your first sentence. It changes what the provider needs to ask you.
This page cannot promise a dispatch time, an arrival window, or that anyone is available right now. The independent company that takes the work confirms that. Report the address, the bay number, whether the opening is exposed, and whether anything hit it.
One local detail that helps after hours: San Antonio's building code provides that "Where equipment replacements and repairs must be performed in an emergency situation, the permit application shall be submitted within the next business day to the Building Official" (City Code Sec. 10-6(f)). A permit question is not automatically a reason to leave a bay standing open overnight.
If the door is stuck open, say so first.
Which commercial doors and facilities belong here?
Included: sectional and overhead doors at commercial buildings, and their springs, cables, drums, tracks, rollers, hinges, struts, panels, bottom bars, operators, controls and sensors. Warehouses, distribution centers, manufacturing plants, cold storage, food and beverage facilities, auto-service bays, fleet garages, workshops, commercial self-storage and other commercial buildings. A small shop with two bays counts.
Not included, and where it belongs:
- Residential garages — a residential garage door company.
- Storefront, glass, automatic-entry and hollow-metal walk-through doors, with their locks, closers and exit hardware — a commercial door and hardware company. "Commercial door" can sound like storefront or locksmith work. This page is about the doors vehicles drive through.
- Truck and trailer cargo doors — a truck or trailer repair shop.
- Rated rolling fire doors — our fire door page.
- Dock levelers, seals, bumpers and restraints — dock leveler repair and dock equipment repair.
- Parts-only requests — a distributor.
- Structural concrete and slab work — a concrete or general contractor.
What happens when you call about the door?
- You describe it. Facility address, bay or door number, what the door is doing.
- 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 whether it can serve the address, the scope, 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: "Bay 7's sectional door is off track at our plant in San Antonio, and I can give you the address." That is example wording, not a real job and not a script.
Useful, but not required: bay number, roughly how wide and tall the opening is, manual or powered, any name you can already see safely from where you are standing, what hit it and when, and how the site is accessed. Call without any of it.
What affects the price, and when is replacement worth discussing?
We can't quote your exact door repair from a web page. The price depends on the door, the fault, parts, and access. Here's what to ask before you authorize work:
- Is there a service-call or diagnostic charge, and does it apply if I don't proceed?
- Is this a standard rate or an after-hours rate?
- Are parts included, and are they in stock or on order?
- Is this a repair, a temporary make-safe, or a replacement?
- What is the warranty on the part, and on the labor?
What moves the number: door width, height and panel gauge; whether one spring or the set is being replaced, and at what cycle rating — DASMA notes that "spring cycle life may not necessarily coincide with door cycle life" (TDS #190); panel availability and lead time for that make; whether the operator, controls or entrapment-protection devices are in scope; whether any electrical work needs a licensed contractor and a permit; access, height and shift constraints; and whether the bay can be out of service while the work happens.
Repair or replace is a conversation, not a verdict from a web page. What a provider weighs: how many panels are damaged and whether the opening is still square; spring and cable age against how many cycles the bay runs; whether the operator is at the end of its life; whether parts are still made for that door. And in the City of San Antonio, replacement carries a permit question that a repair may not — see below, and installation and replacement.
Which San Antonio permit and electrical questions matter?
The city's code answers this in pieces, so here are the pieces.
Ordinary repairs. City Code Sec. 10-6(g) says an application is not required for "ordinary repairs to structures" — but it excludes cutting away a wall or partition, removing or cutting a structural beam or load-bearing support, changing a required means of egress, and "electric wiring or mechanical or other work affecting public health or general safety."
Replacement is listed separately. The city's Minor Commercial Repair Permit application names "Doors (replacement only)" as covered scope, and states that separate permits are required for mechanical, electrical and plumbing work (application form).
And the commercial exemption list is short. The city's commercial permit-process page names painting and floor coverings, minor millwork and cabinetry, and "Replacing existing windows to same size and location" (commercial permit process). Windows are called out. Doors are not on that list.
We are not deciding whether your job needs a permit. The provider and the city's Building Official do. Permits run through BuildSA, city and state licensed contractors must register with Development Services before permits are issued (contractor registration), and fees are on the city's fee schedule rather than anything we would quote.
Outside the city limits it is a different office. In unincorporated Bexar County the County Fire Marshal determines building permit requirements. Confirm the applicable code edition and scope with that office. Schertz, Seguin, Boerne and New Braunfels each run their own permit office and their own adopted editions — the full map is on the metro page.
And the state electrical code just moved. On September 1, 2026, TDLR adopted the 2026 National Electrical Code as the state electrical code, effective the same day (TDLR notice). Several city pages in this metro still list an older NEC. If your job includes an operator circuit, ask which edition the review will use.
One thing this metro does not have: San Antonio is outside the Texas Department of Insurance designated catastrophe area, which covers fourteen coastal counties plus certain cities east of State Highway 146 in Harris County (TDI). The TDI coastal WPI-8 program does not apply at a San Antonio address. That does not remove the need to check the door's required wind-load rating under the local building code.

Commercial overhead door repair questions
My door won't close and keeps reversing at the floor. What is that?
It can involve an obstruction, an entrapment-protection device, the operator's limits or the door's travel. A provider checks the photo eyes, any edge sensor and the complete door/operator system. Never bypass a protection device to make it close.
A forklift hit the door and it looks fine but sticks. Is that a problem?
Worth having looked at. Impact can push the assembly out of square even when the panels look straight, and a door that binds is putting load somewhere it was not designed to go.
Can you just replace the broken panel?
Sometimes. It depends on whether that panel is still made for your door, whether the section above and below took damage, and whether the opening is still square. A provider will tell you after looking.
Do I need a permit to replace a commercial garage door in San Antonio?
Door replacement is listed as covered scope on the city's Minor Commercial Repair Permit, and the commercial exemption list does not include doors. The residential no-permit rule is a different list for different buildings. Your provider and the Building Official confirm what applies. See installation and replacement.
