Replace it, or repair it?

Repair makes sense when the damage can be corrected safely and parts are available. Replacement becomes a better question when damage, obsolete parts or the wrong door specification make repair impractical.

Repair usually still makes sense when the damage is in one or two panels or slats, the opening is still square, the counterbalance is sound, and parts are still made for that door. Replacement starts making sense when the door is damaged beyond a safe repair, the curtain or panels are damaged across their width, parts are no longer available for that make, the operator is at the end of its life at the same time, or the door was never right for how hard the bay is now worked.

An opening knocked out of square needs assessment of the opening and its supports before either choice. If it is a repair, go here instead: commercial overhead door repair · roll-up and rolling steel door repair · high-speed door repair · rolling fire door repair.

Permits: the part most people get backwards

San Antonio lists commercial door replacement on its Minor Commercial Repair Permit application. Confirm the permit and any separate trade work before agreeing the price or installation date.

In the City of San Antonio, commercial door replacement is treated as permitted work. The city's Minor Commercial Repair Permit application lists "Doors (replacement only)" as covered scope, alongside windows, siding, flooring and sheetrock repair. The same form states that structural work needs a Commercial Remodel Permit instead, and that separate permits are required for mechanical, electrical and plumbing work (Minor Commercial Repair Permit application).

That is the opposite of the rule most people have met at home. The city's "No Permit Required" list — which sits under residential projects and says these jobs "typically do not require a permit" — includes "Replacement of existing doors" (No Permit Required list).

Repairs are handled separately again. City Code Sec. 10-6(g) says an application is not required for "ordinary repairs to structures," but 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" (City Code Chapter 10). And if the work is a genuine emergency, Sec. 10-6(f) provides that the permit application "shall be submitted within the next business day to the Building Official."

We are not deciding what applies to your job. The provider and the city's Building Official do that. What this page can do is tell you the questions to ask, and stop you from assuming a residential rule covers a commercial building.

Permits and trade permits run through BuildSA. City and state licensed contractors must register with Development Services before permits are issued, and the city publishes a contractor lookup. Fees are on the city's published fee schedule and estimator — price the permit there rather than accepting a general construction figure as a door number, and ask the provider whether the permit is included in the quote and who pulls it.

Outside the city limits, it is a different office

The mailing address on your invoices does not decide who reviews the work. Whether the building sits inside a city's limits does. If you are not sure, the city publishes a One Stop zoning and address map.

And one thing this metro does not have: San Antonio is outside the Texas Department of Insurance designated catastrophe area, which covers fourteen first-tier coastal counties plus certain cities east of State Highway 146 in Harris County (TDI). That coastal TWIA inspection and WPI-8 certification program does not apply to a San Antonio door. The building-code wind-load requirements for the door and its attachments still matter. If a replacement quote references windstorm certification for a San Antonio building, ask what it is for.

What drives lead time?

We can't give you a date from a web page, and we are not going to invent one. Door supply, opening changes, controls, permits and access set the timetable:

Door type and size. A stock-size sectional and a made-to-measure insulated door are different lead times.
Whether the opening changes. Same opening, same size is one job. A wider opening, a new header or a structural change is another, and it moves you from a minor repair permit to a remodel permit.
Operator and controls. Specifying the operator late can delay the job.
Finish and insulation choices, particularly on cold-storage and food-facility openings.
Whether the existing opening is still square after years of impacts. That gets discovered on survey, not on the phone.
The permit step, where one applies.
Whether the bay can be out of service, or the work has to happen around shifts.

Specifying the door: questions worth asking before you sign

Which mechanism suits how the bay is actually used? A sectional, a coiling door and a high-speed door all close the same hole and behave completely differently. See overhead, roll-up and high-speed.
How many cycles a day will this door run? That drives the counterbalance specification. DASMA notes that "spring cycle life may not necessarily coincide with door cycle life" (TDS #190), so ask what the door is rated for and what the springs are rated for, separately.
Manual or powered, and which operator type? Ask how the jackshaft or trolley operator, and any manual hoist, fit the available headroom and mounting.
What entrapment protection is included? DASMA describes two configurations for operators made after August 2010: constant-pressure-to-close only, or suitable monitored external protection such as an edge sensor, photoelectric sensor or light curtain (TDS #382). Have the provider specify the approved configuration and required protection in the quote. Do not change the operating mode to get around a failed device.
Does this opening need a rated door? If it is in a fire-rated wall, that is a different assembly with its own testing. See rolling fire door repair.
Insulation and sealing at a cooler or freezer opening.
Which company will do the work? Ask who surveys the opening, who installs the door, what experience they have with that door type, and who carries the parts and labor warranty.
Who removes and disposes of the old door?
What the warranty covers on parts versus labor, and who honors it.
Is any electrical work in scope? In Texas, non-exempt electrical work must be performed by a licensed person through a licensed electrical contractor (TDLR Electricians), and the state adopted the 2026 National Electrical Code effective September 1, 2026 (TDLR notice). Several city pages in this metro still list an older edition, so ask which one the review will use. Check the named electrical contractor and applicable individual licenses in the TDLR license search.

What happens when you call?

Describe the openings and what you want to change. The request may be shared with an independent provider, which confirms the scope, price and schedule.

You describe the project. Address, how many openings, what is there now, and whether the opening is changing.
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, scope, availability, pricing, lead time, 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're replacing two bay doors at our building in San Antonio and want to understand the process — I can give you the address." That is example wording, not a real job and not a script.

Useful, but not required: how many openings, roughly how wide and tall, what is there now, whether the opening is changing size, how long the bay can be down, and site access. Use dimensions you already have; do not approach damaged equipment to measure it. Call without any of it.

What is included, and what belongs elsewhere?

Included: installation and replacement of commercial garage, overhead, sectional, rolling steel, roll-up and high-speed doors at commercial buildings.

Not included, and where it belongs: residential garages → a residential company · storefront, glass and pedestrian entrances → a commercial door and hardware company · a new building shell, structural openings and concrete → a general contractor · dock leveler and dock equipment installation → ask on the call, and see dock leveler repair and dock equipment repair · parts-only → a distributor.

What affects the price?

We can't quote a door replacement from a web page. The price depends on the door, the opening, the operator, permits, and access. Here's what to ask before you authorize work:

Is the permit included in this quote, and who pulls it?
Is this a supply-and-install price, or supply only?
Is removal and disposal of the old door included?
Are the operator, controls and entrapment protection devices in the price?
What is the warranty on the door, on the operator, and on the labor — and who honors each one?

What moves the number: door type, size and gauge; whether the opening has to be modified; operator and controls; the permit and trade-permit steps; access, height and shift constraints; removal and disposal; and lead time on the door itself.

Installation and replacement questions

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. The residential no-permit rule is a separate list for different buildings. The provider and the Building Official confirm what applies to your job.

Does the same rule apply in Schertz, Seguin, Boerne or out in the county?

No. Each city runs its own permit office and adopted code editions; in unincorporated Bexar County, the Fire Marshal determines building permit requirements. For another county, confirm the office and project requirements for that address.

Can I replace the door and keep the existing operator?

Sometimes. It depends on the operator's condition, whether it suits the new door's weight and cycle demand, and whether the entrapment protection devices are present and working. Ask for that to be assessed rather than assumed.

How long will it take?

That depends on the door, whether the opening changes, the operator specification, and the permit step. Ask the provider for a lead time on the door and a separate one for the install window — those are two different numbers, and being given one figure for both is where schedules slip.
