Which dock or door service do you need?

Pick the closest match. If none of them looks right, call and describe what you are looking at.

Loading dock and dock door repair — you are on the right page.
Commercial garage and overhead door repair — sectional bay doors that run up a track: springs, cables, rollers, panels, operators.
Commercial roll-up and rolling-steel door repair — a curtain of slats that coils onto a barrel above the opening, plus sheet doors and grilles.
Dock leveler repair — the platform in the dock floor that bridges to the trailer. Won't raise, won't hold, lip won't fold out, leaking.
Dock seals, shelters, bumpers and plates — the rest of the dock face.
Trailer restraints and dock locks — the device that holds the trailer, plus the red and green lights and interlocks that go with it.
High-speed and cold-storage doors — fast fabric and rigid doors, cooler and freezer openings.
Rolling fire door repair, inspection and drop testing — rated doors with automatic closing systems.
Planned maintenance — a schedule instead of a breakdown.
Installation and replacement — replacing a door rather than repairing it.

What kind of equipment is this?

Most calls start with a description, not a part number. If you can name roughly what you are looking at, the provider can tell you what a visit would involve. You do not need to be right — that is what the visit is for.

Two words get mixed up constantly, so here is the plain version. Dock door, also called a loading 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. The dock equipment under it is a separate system.

What you are looking at	What people call it	Which service that is	What to mention on the call	What it is not
A big door at a truck bay made of horizontal panels that rolls up a track into the ceiling	Sectional door, overhead door, bay door, dock door	Commercial overhead door repair	Bay number, whether it is stuck open or closed, whether anything hit it	Not a coiling curtain, not a walk-through door
A door made of one curtain of interlocking slats that coils onto a barrel above the opening	Roll-up, rolling steel, coiling door	Roll-up and rolling steel door repair	Whether the curtain is bent, jammed or out of the guides	Not a sectional door
A thin corrugated curtain, common on self-storage and light commercial openings	Rolling sheet door	Roll-up and rolling steel door repair	Whether the curtain is creased or the bottom bar is bent	Not a rated fire door
A fabric or rigid door that opens fast, often inside the building or on a cooler	High-speed, rapid-roll, high-performance door	High-speed door repair	Whether the curtain tore, whether it lost its position, whether a forklift hit it	Not an ordinary roll-up
A rolling door identified as fire-rated by its listing label or facility records	Rolling fire door, fire shutter	Rolling fire door repair	Whether it has dropped, and whether you have an inspection report	A dropped rated door is not reset like an ordinary door
A steel platform set into the dock floor, hinged at the back, with a lip that folds onto the trailer	Dock leveler, dock ramp, "dock lever"	Dock leveler repair	Which bay, and whether it is stuck up, stuck down or will not hold	Not a portable plate
A loose metal plate or ramp you set down between dock and trailer and pick back up	Dock plate, dock board	Dock equipment repair	Whether it is bent or cracked, and the capacity marked on it if you can already see it	Plates and boards are different products with different traffic ratings
Foam pads or fabric curtains around the opening that the trailer presses against	Dock seal, dock shelter	Dock equipment repair	Which side is torn, and whether a trailer pulled away with it	Not part of the door
Rubber or laminated blocks bolted below the opening that the trailer backs into	Dock bumper	Dock equipment repair	Which bay, and whether the bumper is missing or the mounting is torn out	Not a vehicle bumper
A hook, barrier or wheel device at the dock face that grabs the trailer	Vehicle restraint, trailer restraint, truck restraint, dock lock	Trailer restraint repair	What the red and green light is showing, and whether the restraint will release	Not a leveler
Red and green lights and a control box inside and outside the bay	Dock communication system, dock lights, interlock	Trailer restraint repair	Which inside and outside lights or messages are showing	The door and restraint controls can be linked
The motor and control unit that runs a bay door	Operator, opener, jackshaft, trolley operator	Commercial overhead door repair	Whether it hums, trips a breaker, or does nothing	A door operator is not the same thing as a gate operator

Brand names help, but you never need one. Dock-equipment nameplates may carry names like Rite-Hite, Kelley, Serco, Blue Giant, Nordock, Pentalift, Poweramp, McGuire or Bluff. Doors may say Overhead Door, Clopay, Wayne Dalton, Raynor, Amarr, C.H.I., Janus, Cornell, Cookson, Rytec or Hörmann. Those are examples so you can recognize a nameplate — not a claim about what is installed at your building, and not a dealer or authorized-service relationship.

You can call without a model number, a measurement, a photo or a diagnosis. The facility location, the bay number and "stuck open" are enough. Never walk up to a damaged door, a broken spring, a raised leveler or a stuck restraint to read a label.

What problems can you describe on the call?

You do not need to know what broke. Describing what the equipment is doing is enough for a provider to tell you what a visit would involve. Nobody on this page can diagnose your equipment from a description, and we are not going to pretend otherwise.

What you are seeing	What a qualified provider inspects	Why it matters	How to say it on the call
Bay door stuck part-way open	Counterbalance, cables and drums, track alignment, operator and controls	An open bay is an exposed building, and a door held by a damaged counterbalance can move without warning	"Bay 4 is stuck about halfway open"
A bang, and now the door will not move at all	Spring and counterbalance condition, cables, whether the door is now held only by the operator	A damaged counterbalance can leave the door unsupported; do not operate the release	"Something banged and now it won't move"
Door came off the track, or the curtain is out of the guides	Guides, rollers, hinges, panel or curtain damage, whether a vehicle struck it	A door that is only partly retained can fall	"One of the tracks came off — it's the top one"
A forklift or trailer hit the door	Panel or slat deformation, frame and jamb, guide straightness, operator alignment	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"
Leveler will not raise, or raises and will not stay up	Which mechanism it is first — mechanical, hydraulic or air — then the hold-down, cylinder, power unit or springs	Unexpected movement is a hazard; normal trailer-following movement depends on the model	"The ramp won't pop up on bay 2"
Leveler lip will not fold out onto the trailer	Lip assembly, lip-assist mechanism, whether the deck is sitting level	Without the lip there is no safe bridge to the trailer	"The lip won't come out on bay 2"
Fluid on the pit floor under the leveler	Hydraulic lines, fittings, cylinder seals	A leak can affect operation and needs assessment	"There's oil in the pit under bay 2"
Door will not lift and the dock lights or display seem wrong	Door, restraint, communication system and their interlocks against the model instructions	A light color alone does not identify the fault or establish that loading is safe	"The door won't go up and the dock display is showing a fault"
Restraint will not grab the trailer, or will not let go	Restraint type, its sensing and controls, the trailer's rear impact guard, the interlock logic	A trailer that can move during loading is exactly what the federal rules on chocks and brakes are about	"The dock lock won't release on bay 6"
Seal or shelter torn, foam hanging	Seal condition, mounting, whether a trailer pulled away against it	Lost conditioned air, water in the bay, and torn material that catches the next trailer	"The driver's-side seal got ripped off bay 11"
Bumper missing or mounting torn out	Bumper condition and mounting, dock-face damage behind it	Without the bumper, the dock face takes the hit instead	"The bumper's gone on bay 3"
Rated rolling door dropped and will not go back up	Whether the door is rated, its release mechanism, and what the drop-test record shows	A dropped rated door is not reset the way an ordinary door is	"The fire shutter came down"

One safety note, and we will keep it short. This page does not tell you how to fix anything. Springs, cables, counterbalances, hydraulics and operator wiring get inspected by qualified people. Until someone looks at it: keep people clear of the opening, do not force the equipment, and follow your facility's established process for taking the affected bay out of use.

Need emergency dock door repair in San Antonio?

If a bay door is stuck open or a dock position is down, say that in your first sentence when you call. It changes what the provider needs to ask you. This page cannot promise a dispatch time, an arrival window, or that anyone is free right now — the independent company that takes the work confirms that. The four details below keep the request clear.

Report these four things:

The facility address.
Which bay or door number.
What the equipment is doing, in plain words — stuck open, will not lift, dropped, will not hold.
Whether the opening is exposed right now, or a trailer is stuck at it.

While you wait, keep people and equipment clear of the opening, do not force the door or the leveler, and take the bay out of use through your facility's normal process. Do not approach the equipment, move it, reset it or try to inspect it.

There is one San Antonio detail worth knowing when something breaks after hours. The city's building code has an emergency provision: "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 Chapter 10, Sec. 10-6(f)) So a permit question is not automatically a reason to leave a bay open overnight. Whether your specific job needs a permit at all is for the provider and the city to confirm — see the local checks further down.

If the dock is down, say so first.

CALL NOW — COMMERCIAL LINE(385) 325-7138

What happens when you call?

Describe the facility, the affected bay and what stopped working. The request may be shared with an independent company, which confirms availability, scope and charges before work is agreed.

You describe it. Facility location, bay or door number, what the equipment 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 everything that matters — whether it can serve the address, the scope of work, availability, pricing, scheduling, and its own contract, work and warranty terms. Not us.

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 4 is stuck halfway open at our warehouse in San Antonio, and I can give you the address." That is example wording, not a real job and not a script. Say it however you normally would.

CALL NOW — COMMERCIAL LINE(385) 325-7138

What is useful to have, but not required?

None of this is homework. Call without any of it.

Bay or door number
Roughly how big the opening is
Whether the door is manual or powered
Any name or plate on the equipment that you can already see safely from where you are standing
Whether anything hit it, and when
Whether the site has a gate, a check-in process, or restricted access hours

What equipment and facilities fit this request?

We take calls about loading dock equipment — levelers, seals, shelters, bumpers, plates and boards, dock lights, wheel chocks, vehicle restraints and dock communication systems — and building-mounted commercial doors: garage, overhead, sectional, rolling steel, roll-up, sheet and high-speed. At warehouses, distribution centers, manufacturing plants, cold storage, food and beverage facilities, auto-service bays, fleet garages, workshops, commercial self-storage and other commercial buildings.

Your building does not have to be a giant distribution center. A four-bay shop counts.

We do not take calls about these, and here is where they belong:

Residential garages — a residential garage door company.
Boat docks and boat lifts — a marine contractor. Worth saying plainly, because searching "dock repair" in Texas turns up a lot of boat docks. This is the other kind of dock.
Truck and trailer cargo doors — the doors on the vehicle itself — a truck or trailer repair shop.
Pedestrian storefront, automatic-entry, glass and hollow-metal walk-through doors, with their locks, closers and exit hardware — a commercial door and hardware company.
Parts-only requests — a distributor.
Structural concrete, dock pit and slab work — a concrete or general contractor. We take calls about the equipment in the pit, not the pit itself. That line matters: some companies list concrete ramp repair next to leveler repair, and they are different trades.

What affects the cost of a San Antonio dock or door repair?

We can't quote your exact repair from a web page. The price depends on the equipment, 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 still apply if I decide not to proceed?
Is this quoted at 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 — and what is the difference in price?
What is the warranty on the part, and on the labor?

Five words get used as if they mean the same thing. They do not.

Call-out or diagnostic fee — what it costs to get someone there to look.
Starting price — the lowest a job of that type goes for. Yours may not be that job.
Scoped fixed price — a set price for a defined piece of work, once someone knows what the work is.
Estimate — an informed guess before the full picture is known.
Final quote — the number you are actually agreeing to, for a scope you can read.

Ask which one you are being given, and what is inside it.

What actually moves the number:

Driver	Why it changes the price	What to ask
Diagnostic and travel	Getting a qualified person to the site is real work	Is it charged separately, and is it credited if I proceed?
After-hours timing	Some companies price nights and weekends differently	Is this a standard or after-hours rate?
Part availability	An in-stock part and a six-week part are different jobs	Is the part on the truck, in stock, or on order?
Door size and gauge	A 14-foot insulated door is not a 9-foot one	What size and construction are you pricing?
Springs and counterbalance	Spring cycle life and door cycle life are not the same thing (DASMA TDS #190)	Are you replacing one spring or the set, and what cycle rating?
Operator, controls and sensors	Entrapment-protection devices are part of the system, not an add-on	Does this include the sensors and controls?
Leveler mechanism	Mechanical, hydraulic and air-powered levelers have completely different parts lists	Which mechanism are you pricing?
Fire rating	A rated assembly has listed parts and documentation	Is this a rated door, and does the price include the record?
Access	Clearing a bay, working around shifts, or a height issue all add time	Do you need the bay empty, and for how long?
Lead time	A temporary make-safe now plus a repair later is two visits	What is the lead time, and what happens in between?

Repair the dock or door, or replace it?

Ask for a scoped repair option and, where the condition warrants it, a replacement option. The useful comparison is safe operation, compatible parts, repeated failures, downtime and whether the equipment still fits the facility's traffic—not age alone.

Have the provider explain what can be restored, what cannot, and the lead time for each option. For a new door, operator or changed opening, see commercial door installation and replacement; for the platform itself, see dock leveler repair.

What should you check before authorizing work in San Antonio?

Two things about Texas surprise people, and both are worth knowing before you sign anything.

"Licensed" means something narrower here than it sounds

Ask what license or registration covers the actual work, who holds it, and where you can verify it. A claim to be "licensed" is not enough by itself; mechanical repair, electrical work and alarm-connected controls can raise different questions. Start with the TDLR license programs and the city registration lookup below.

Electrical work is licensed. Non-exempt electrical work has to be performed by a licensed person working through a licensed electrical contractor, and TDLR runs a public license search. (TDLR Electricians; Active License Search.) That matters here because running a new circuit and disconnect for a door operator, or a power feed for a leveler, can cross into regulated electrical work. It does not mean every mechanical door repair needs an electrician, and it does not mean low-voltage work is automatically exempt. Ask which company holds the credential for that part of the scope.

The state electrical code changed on September 1, 2026. The Texas Commission of Licensing and Regulation announced amendments to 16 TAC §73.100 that "adopt the 2026 National Electrical Code as the state electrical code, with a limited exception pertaining to ground-fault circuit interrupter requirements for certain outdoor outlets," effective September 1, 2026. (TDLR rulemaking notice, September 1, 2026.) Several city pages around this metro still list an older NEC. If your job involves an operator circuit, ask which edition the permit will be reviewed against.

Operators are their own question. Texas DPS states that installing garage door openers or electronic gate openers needs no DPS license when no other activity regulated by Occupations Code Chapter 1702 is performed, and that this "includes installers of operators for gates and residential or commercial garage or upward-acting doors." But it also states that "the installation of a gate or garage/upward-acting door operator that is connected to an alarm system or that allows for monitoring or logging of ingress/egress does require a license." (Texas DPS — gate operators and garage door openers.) The trigger described here is alarm connection or monitoring/logging access, not whether the door is commercial.

City registration is a separate layer. San Antonio requires city and state licensed contractors to register with Development Services before permits are issued, and the city publishes a contractor lookup. (Contractor Registration; Find a Contractor.) Ask Development Services which registration covers the proposed commercial work; electrical contractors must register their state license with the city. Several suburbs run their own registration: Schertz states that "All contractors performing work for which a permit is required in the City of Schertz shall be registered with the City," Seguin "requires all contractors to be registered with Development Services Center prior to the issuance of any permit(s)," and Boerne says contractors "must be registered with the City of Boerne to work in the city limits and to submit the permit applications required for projects."

Does commercial door work need a permit in San Antonio?

It depends on what the work actually is, and the city's code answers it in three pieces rather than one.

Ordinary repairs. City Code Sec. 10-6(g) says an application is not required for "ordinary repairs to structures." But it draws a hard line around what that covers: ordinary repairs do not include cutting away a wall or partition, removing or cutting a structural beam or load-bearing support, removing or changing a required means of egress, or "electric wiring or mechanical or other work affecting public health or general safety."

Replacement is treated differently. 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 says 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.)

And this is where people get caught out. A residential permit list does not decide the rules for a commercial warehouse. The commercial application explicitly includes door replacement; ask the city which permit path fits the actual work.

So if you have replaced a door at home and assumed the same rule applies at the warehouse, check before you assume. We are not deciding whether your job needs a permit — the provider and the city's Building Official do that. Permits and trade permits run through the city's BuildSA portal, and fees are on the city's published fee schedule and estimator. Ask the provider what the permit step adds to the timeline, and price the fee at the city's own schedule rather than taking a general construction figure as a door number.

Which building department has your facility?

The mailing address on your invoices does not decide this. The facility's actual jurisdiction does, including any applicable city ETJ review.

Where the facility is	Who handles the building permit	Adopted codes, as published	What that changes
Inside San Antonio city limits	City Development Services, through BuildSA	2024 IBC, IEBC and IFC and the related ICC codes, Ordinance 2025-01-30-0075, effective May 1, 2025; that document records 2023 NEC and 2021 IECC at that date	Pair the city's electrical entry with the state's September 2026 NEC update and let the reviewer confirm which applies
Unincorporated Bexar County	Bexar County Fire Marshal determines building permit requirements outside municipal limits	Ask the County Fire Marshal which adopted edition applies to the work	A different office from City Development Services; confirm any Public Works or city ETJ review
Schertz	City of Schertz Inspections, CityView portal	2018 IBC, IFC and IEBC; the city notice specifies 2026 NEC for permit applications from September 1, 2026	Contractors doing work that requires a permit must register with Schertz
New Braunfels	City Building Safety, nbpermits portal	2021 IBC, IFC and IEBC, effective October 23, 2023; confirm electrical scope against the state update	Straddles Comal and Guadalupe, so work outside the city limits splits between two counties
Seguin	City Permits and Inspections, Development Services Portal	2021 IBC and 2018 IFC; the page lists 2023 NEC	Building and fire code editions differ; confirm electrical scope against the state's 2026 NEC update
Boerne	City Permitting and Code Compliance, MGO platform	2021 IBC, IRC, IMC, IPC, IPMC, IECC and IFC, plus 2023 NEC	Kendall County, its own fire marshal, its own development code
Unincorporated Comal County	Comal County Fire Marshal	2024 IFC, under the county fire code	Permits apply to a new commercial building, a remodel for a new type of business, or multifamily of four or more units
Unincorporated Guadalupe County	Guadalupe County Fire Marshal	Adopted the 2024 International Fire Code for unincorporated Guadalupe County on January 27, 2026	Same fire code edition as the City of San Antonio

Cross a city limit line in this metro and the building code edition can shift by six years. Schertz sits on the 2018 codes, Boerne on the 2021 codes, and San Antonio on the 2024 codes — three neighboring jurisdictions, three editions, all current as published on September 19, 2026. Worth confirming before a quote assumes one of them.

If you are not sure which side of a line your building is on, the city publishes a One Stop zoning and address map. The provider and the issuing office confirm what actually applies.

One thing this metro does not have

San Antonio is not in the Texas windstorm region. The Texas Department of Insurance designates the catastrophe area as fourteen first-tier coastal counties — Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Refugio, San Patricio and Willacy — plus certain cities east of State Highway 146 in Harris County. (TDI windstorm questions.) No county in the San Antonio metro is on that list. The coastal WPI-8 program is a different question from the wind loads required by the building code. If a quote references windstorm certification for a San Antonio building, ask what it is for and what design wind pressure the opening requires.

Rated fire doors

A fire-rated rolling door has its own inspection and testing requirements. Have the provider identify the assembly from its listing label, manufacturer information and facility records; automatic closing alone does not establish its rating. San Antonio adopts the 2024 International Fire Code with local amendments. DASMA TDS #271 recommends arranging annual, or more frequent, inspection and drop testing with a rolling-door service provider. Ask what training the technician documents, what record you will receive, and which adopted NFPA 80 edition and requirements the local fire authority applies. Full answer: rolling fire door repair, inspection and testing in San Antonio.

The safety standards under this equipment

These are the same everywhere, and they are useful background rather than a legal checklist.

OSHA's dockboard rule requires dockboards capable of supporting the maximum intended load, run-off protection for dockboards put into service on or after January 17, 2017 (with the employer-demonstrated no-run-off-hazard exception), portable dockboards secured against moving out of a safe position (or sufficient contact where the employer demonstrates securing is infeasible), measures "such as wheel chocks or sand shoes" to keep the transport vehicle from moving while employees are on the dockboard, and handholds or other means of safe handling on portable dockboards (29 CFR 1910.26). The powered industrial truck rule requires that highway truck brakes be set and wheel chocks placed under the rear wheels before a forklift boards them (29 CFR 1910.178). The fall protection rule sets a four-foot threshold, with specific exceptions written for loading docks and for dockboards used with motorized equipment (29 CFR 1910.28).

The ANSI MH30 series covers dock leveling devices (MH30.1), portable dock leveling devices such as dock plates and dock boards (MH30.2), and vehicle restraining devices (MH30.3) (MHI LODEM). Door and gate operators fall under ANSI/CAN/UL 325. Whether any of these applies to a specific job is for the provider and the enforcing authority to work out, not a web page.

Planning maintenance instead of reporting a breakdown?

Maintenance is a different call, and mixing it with a breakdown wastes everyone's time. For rolling doors, DASMA says a trained door systems technician should perform periodic inspection and maintenance "at least annually or per the door manufacturer's recommendations," that the performance of electric doors should be evaluated quarterly, and that an event such as high wind, seismic activity or flooding should trigger an immediate evaluation (DASMA TDS #270). See planned maintenance.

Replacing a door rather than repairing it is a different call again — specification, lead time, opening prep, and in San Antonio a permit question. See installation and replacement.

Questions before you call

Can I call if I don't know what the equipment is or who made it?

Yes. Start with the facility address and what the equipment is doing, or not doing. You do not need a model number, a measurement or a photo, and you should not walk up to damaged equipment to get one.

Do you fix boat docks?

No. This is commercial loading dock equipment and commercial doors at buildings. Boat docks and lifts are a marine contractor's work.

How fast can someone get there?

This page cannot promise a time. Call, describe it, and lead with "stuck open" or "the dock is down." The independent company that takes the work will tell you what it can do.

Who actually does the repair?

An independent commercial dock-and-door repair company. Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair. We do not perform repairs, employ technicians, diagnose equipment, set prices or provide the warranty.

Do I need a permit to work on a commercial door in San Antonio?

It depends on the work. The city's code exempts ordinary repairs, but that exemption does not cover electric wiring, changes to a required means of egress, or structural work. Door replacement is listed as covered scope on the city's Minor Commercial Repair Permit. And where a repair is a genuine emergency, the code provides for the permit application to be submitted the next business day. The provider and the Building Official confirm which of those your job is.

Our building is outside the city limits. Same rules?

No. Outside municipal limits in Bexar County, the County Fire Marshal determines building permit requirements and confirms the code edition applicable to the work. Schertz, Seguin, Boerne and New Braunfels each run their own permit office and their own adopted editions.

Is our rolling door fire-rated, and does it need testing?

Have the provider confirm the fire rating from the listing label and records; automatic closing alone does not prove it. DASMA recommends annual, or more frequent, inspection and drop testing. Ask what training the technician documents, what record you get, and which adopted NFPA 80 requirements the local fire authority applies.

Can you handle more than one facility?

You can call about more than one facility. Give each address; the independent provider confirms whether it can serve each location.

Call about the dock or door at your facility

Tell us where the building is and what stopped working. That is enough to get started.
