This is commercial work. Fourteen-foot insulated sectionals at dock height, three-phase operators, multi-bay warehouse and plant buildings across Berkeley, Charleston and Dorchester counties. We don't do residential garages. Search results for "commercial garage door repair" in this metro are crowded with house-garage companies, so it's worth saying plainly.
"Commercial garage door" and "commercial overhead door" are two names for the same equipment. One page, both words.
Is this the right page? Sectional, rolling, high-speed and fire-rated doors are different equipment
Calling the wrong equipment by the wrong name is the most expensive mistake on a commercial door call. Here's how to tell them apart in about five seconds.
| What you can see | What it's called | The key mechanical difference | Who handles it |
|---|---|---|---|
| Horizontal panels that slide up onto tracks along the ceiling, springs across the top of the opening | Commercial sectional or overhead door | Counterbalance springs and ceiling tracks | This page |
| Interlocking steel slats that coil into a barrel above the opening | Rolling steel or coiling door | Coils into a drum, no ceiling tracks | Roll-up & rolling-steel door repair |
| Fabric or rigid door that opens in a few seconds, often at a cooler or freezer | High-speed door | No counterbalance springs; breakaway bottom bar | High-speed & cold-storage door repair |
| Rolling door with a release device or fusible link, over an opening in a fire wall | Rolling fire door | Designed to close on its own in an alarm; needs a trained fire door technician | Rolling fire door repair |
If you're not sure, say so on the call and describe what you see. It settles quickly.
What's on a Charleston commercial building
Door types. Insulated and non-insulated sectionals, full-vision sectionals, dock-height doors, drive-through doors.
Counterbalance. Most commercial sectionals use a torsion spring — a spring wound around a shaft above the opening that stores energy to offset the door's weight. Some use extension springs along the tracks. Either way, the spring is doing most of the lifting, not the operator.
The rest of it. Tracks and rollers, hinges, cables and drums, panels and sections, bottom bar and astragal, struts, and the operator with its controls and sensors.
Nameplates you may see. Overhead Door, Clopay, Wayne Dalton, Raynor, Cornell, Cookson. These are identification examples only — not a statement about what is installed at Charleston facilities, and not a claim of authorized service or dealer affiliation for any brand.
Only report a nameplate you can already see from where you're standing. Never approach a damaged door or a broken spring to read one.
What's it doing? Commercial door symptoms
Describe what the door is doing and skip the diagnosis. That's the job of the person who comes out. This table is here so you know what you're looking at and what to say.
| What you're seeing | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| Stuck part-way open | Tracks, rollers, cables, counterbalance, operator limits | A door stopped mid-travel may be holding weight it wasn't designed to hold | "Bay 4, stuck about halfway" |
| Visibly off track after an impact | Track alignment, rollers, hinges, panels, jamb and frame | Forcing an off-track door usually turns a small repair into a big one | "Forklift hit bay 2, off track on the left" |
| Loud bang, then the door won't move | Springs, cables, drums, bottom brackets | This is the highest-hazard failure on a commercial door | "Heard a bang, door won't lift at all" |
| Closes then immediately reverses | Photo eyes, safety edge, operator settings, travel limits | Often the safety system working correctly, not failing | "Goes down a foot then back up, every time" |
| One side higher than the other | Cables, drums, shaft, track alignment | A door hanging crooked is loading its hardware unevenly | "Door is cocked, left side is lower" |
| Panel crushed at dock height | Panel and section condition, struts, hardware, track | Damaged panels can bind the whole door | "Bottom two panels are caved in on bay 6" |
| Runs but strains, judders or is noisy | Rollers, bearings, shaft, springs, operator, lubrication points | Noise usually means something is working harder than it should | "It runs but it's grinding" |
| Operator hums, door doesn't move | Drive coupling, chain or belt, clutch, shaft, operator | Running an operator against a stuck door can damage more than the door | "Motor runs, nothing moves" |
| Photo eye light out or flashing | Sensor alignment, mounting height, wiring, operator monitoring | A door that won't close may be reporting a real sensor problem | "Little light by the floor is flashing" |
| Door drifts down when stopped | Counterbalance, cables, brake, operator | A door that won't hold position is a hazard under the opening | "Won't stay where I put it" |
The spring is the part to leave alone
A broken spring or cable leaves a commercial door with stored tension that can move without warning. Keep everyone clear of the opening and clear of anything under tension. Don't force the door. Don't let anyone examine, adjust or release the spring, cable or bottom bracket.
This is not being overcautious. The door industry's own inspection guidance on spring-tension components is to look and do not touch. That guidance is written for trained inspectors. It applies double to everyone else.
If the door is unsafe, follow your facility's existing process for taking that bay out of use. Then call.
Call (385) 325-7138 and say the bay number and what the door is doing.
Operators, controls and sensors
The operator is the motor and gearbox that runs a powered door. Most commercial doors use a trolley operator (mounted on the ceiling, pulling the door along a rail), a jackshaft operator (mounted on the wall beside the shaft), or a hoist operator. Controls are usually a three-button station — open, close, stop. Sensing devices are the photo eyes near the floor and sometimes a safety edge on the bottom bar.
Here's the part almost nobody asks about, and it decides whether a "sensor problem" is a fault or the system doing its job.
| Operator age | What the safety standard requires | What it means for your repair | What to ask |
|---|---|---|---|
| Manufactured before August 29, 2010 | Constant-pressure-to-close only, a three-button control, or a suitable external entrapment protection device where the door is run by remote or unattended features | An older operator may not be checking whether its sensors are working | "Does this operator monitor its entrapment protection?" |
| Manufactured on or after August 29, 2010 | The door industry states the operator "must continuously monitor the external entrapment protection device so that the door cannot be started down unless the device is properly functioning" | A failed, misaligned or disconnected sensor can correctly stop the door from closing. That's the system working, not breaking | "Is the sensor the cause, or a symptom of something else?" |
| Any operator using photoelectric sensors for monitored protection | Sensors "must be installed parallel to the floor with the internal photoelectric beam no higher than six inches above the floor" | A sensor mounted at the wrong height may not be protecting the opening it's supposed to protect | "Are the photo eyes mounted at the published height?" |
That August 2010 date is the one to remember. Operators made from then on are expected to watch their own safety devices. So "the door won't close and the light is blinking" is often a correctly-working door refusing to close on a fault — which is a very different repair from a broken door.
Uptime's national reference on UL 325 commercial door requirements goes deeper on the standard itself.
Call (385) 325-7138 and say whether the door runs at all.
Need emergency commercial garage door repair in Charleston?
If a commercial door is stuck open, your building is open. If it's stuck closed across a lane, your shift is blocked. Either way, say that first when you call — the urgency belongs at the top of the sentence, not at the end.
We can't promise a technician, a time, or an outcome from this page. A published service-request line does not mean that a specific repair company has already accepted the job, confirmed current availability, or agreed to every type of work described on the website. The independent company that takes the work confirms availability, scope and price with you directly.
Report these, in this order: facility address · bay or door number · what the door is doing · whether the building is open to the outside · whether the bay is out of service · a callback number · how someone gets on site.
While you wait: keep people and lift trucks clear of the opening. Don't force the door. Follow your facility's process for taking the bay out of use. Don't send anyone to inspect a spring, a cable or a bottom bracket.
If the door is stuck open, say so first.
What we cover — and what we don't
Covered: building-mounted commercial garage, overhead and sectional doors at warehouses, distribution centers, plants, cold storage, food and beverage facilities, auto-service bays, fleet garages, workshops, commercial self-storage and other commercial buildings.
Not covered:
- Residential garages. Different parts, different trade. A house garage company is who you want.
- Pedestrian storefront, automatic-entry, glass and hollow-metal walk-through doors, with their locks and closers. That's a storefront or door-hardware contractor, not us.
- Truck and trailer cargo doors. The door on the trailer isn't ours.
- Parts-only requests. We take service calls, not parts orders.
- Structural concrete, pit and slab work.
What happens when you call (385) 325-7138?
- You describe the door. Facility address, bay number, what it's doing. No model number, photo or measurement needed.
- We route your call. The request is shared with an independent commercial dock-and-door repair company. Uptime Dock & Door does not repair equipment and does not send technicians.
- That company confirms everything with you — access, scope, availability, price, scheduling, and its own contract, work and warranty terms.
Example wording: "Bay 4 is stuck halfway open at our warehouse in Charleston, and I can give you the address."
That's an example of a good first sentence, not a script and not a real job.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
What's useful to have on the call — if you already have it
None of this is required. Call without it.
- Roughly how wide and how tall the door is
- Insulated or not
- Manual or powered, and single-phase or three-phase if you know
- Roughly how old
- What changed right before it failed
- How someone gets on site
- Who authorizes the work
What drives the cost of a commercial door repair in Charleston?
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.
Ask about the shape of the price, not just the number. A call-out or diagnostic fee pays for the look. A starting price is a floor for a job type. A scoped fixed price covers a defined list. An estimate is a considered guess. A final quote is a commitment to a number for a defined scope. Find out which one you're being given, and what's included.
| Driver | Why it moves the price | What to have ready |
|---|---|---|
| Door size and gauge | Heavier doors mean more material, more labor, sometimes more people | Rough width and height |
| Insulated vs non-insulated | Insulated panels cost more and are heavier to handle | Whether the opening is conditioned |
| Spring system type and condition | Decides whether this is a component swap or a counterbalance rebuild | Whether you heard a bang |
| Cables, rollers, tracks and hinges | Impact damage usually takes several of these together | What was hit and where |
| Panel or section replacement | Section availability and color match drive both cost and lead time | Which panels are damaged |
| Operator type, phase and age | Older operators may need control or safety-system work alongside the repair | Powered or manual, and roughly how old |
| Working height and access | High openings and live dock traffic add time and equipment | Anything unusual about getting to it |
| Whether the bay must stay in service | Working around production costs more than working on a shut bay | Whether you can take the bay down |
| Timing | Work outside normal hours is priced differently | When you need it usable |
Uptime does not set, see, or take part in pricing. That's between your facility and the repair company.

Repair or replace a commercial door?
Some honest factors, in the order they usually matter:
- Is the same fault repeating? Repeat visits for one problem usually mean something underneath hasn't been fixed.
- Are panels and sections still available? When they go to factory-order, replacement math changes.
- How old is the operator? An operator made before August 2010 may not monitor its safety devices, which matters if you're already spending money on the door.
- Is the door the problem, or the opening? A door hung in a bent frame will keep failing.
- Has the requirement changed? If the opening now needs a wind rating, replacement brings documentation with it.
Planning a replacement rather than a repair? That's a different conversation with different questions — see commercial garage & overhead door installation.
Before you hire in Charleston: the door-relevant rules
We can't tell you whether a permit or a license applies to your door. The rule, where to check it, and what to ask is the ceiling. The provider and the issuing office confirm the rest.
The license question. South Carolina requires a license for contracting work where "the total cost of construction is greater than ten thousand dollars for general contracting or greater than ten thousand dollars for mechanical contracting" (SC Code §40-11-30, checked 2026-09-21). There is no South Carolina classification called "overhead doors." What exists is Building — "commercial, industrial, institutional, modular, and all other types of building construction" — and a Nonstructural Renovation subclassification that expressly includes "window and door installation" (§40-11-410). Classification follows the scope.
The wiring question. South Carolina is specific: "A contract that contains electrical work above fifty volts must be performed by a contractor licensed under this subclassification" (§40-11-410). So a job that replaces a door and wires a new operator can involve two different licenses. Worth one question.
The easy check. On permitted work, the permit is itself a license check — a building official "shall refuse to issue a permit… unless the applicant has furnished evidence that the applicant is either licensed as required by this chapter or exempt" (§40-11-350). Outside that, South Carolina publishes a contractor license lookup.
The permit question. No jurisdiction in this metro publishes a rule specifically about commercial doors. Mount Pleasant's is the clearest general language in the area: a permit is required to "erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system" (Town of Mount Pleasant, checked 2026-09-21). Which office covers your parcel depends on the address — see the Charleston service area.
Wind rating on a replacement door: see installation. Fire-rated doors are a separate compliance task: see rolling fire door repair.

Commercial door questions Charleston facility managers ask
My door is off track after a forklift hit it — is that a repair or a replacement? Usually a repair, but it depends on what moved. An impact can bend track, damage rollers and hinges, crush panels, and pull the frame. Sometimes it also stresses the counterbalance. Don't run the door to find out. Describe what was hit and where.
The door reverses every time it closes. Is that the sensors or the door? It may be neither — it may be the operator doing its job. Operators made on or after August 29, 2010 are expected to continuously monitor their entrapment protection and refuse to close when it isn't working. A blocked, misaligned or damaged photo eye produces exactly this behavior. That's a different fix from a mechanical fault, which is why it's worth reporting the blinking light rather than just "it won't close."
Do you work on three-phase commercial operators? Yes — three-phase powered doors are normal commercial equipment on this page. Mention the phase if you know it; skip it if you don't. Be aware that operator wiring above fifty volts is its own licensed scope in South Carolina, so ask who's handling that part.
Is a commercial garage door the same as a commercial overhead door? Yes. Different words, same equipment — a sectional door that rolls up onto ceiling tracks. That's why one page covers both rather than splitting them. What's genuinely different is a rolling steel door, a high-speed door and a fire-rated door, each of which has its own page.
Do you do residential garage doors? No. Residential garage doors are a different trade with different parts and different pricing. If your door is on a house, a residential garage door company is who you want.
Call about the door that's down
Tell us the facility address, the bay number, and what the door is doing. That's enough.
