Start here: what broke, and who handles it
Three paths cover most calls. Commercial garage and overhead doors — the big sectional doors on ceiling tracks. Commercial roll-up and rolling-steel doors — the ones made of steel slats that coil into a barrel. Loading dock equipment — levelers, seals, shelters, bumpers, plates and restraints.
Not sure which one you've got? That's normal. Skip to the equipment table or just call and describe what you can see.
One thing worth saying up front, because Charleston is a waterfront city: this is commercial loading-dock and building-door work. Not boat docks, piers or seawalls. If that's what you need, a marine dock contractor is who you want.
We take calls about facilities across Berkeley, Charleston and Dorchester counties — Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, Ladson, Hanahan, Moncks Corner and the rest of the tri-county area. See the full Charleston service area.
Ready when you are.
Not sure what you're looking at? Find your equipment here
You don't need the right word for it. You need to describe what you can see. This table does the translating.
| What you can see | What it is | Who handles it | What to mention on the call | Where the boundary is |
|---|---|---|---|---|
| Big door made of horizontal panels, rolls up on tracks along the ceiling, springs across the top | Commercial sectional or overhead door | Commercial garage & overhead door repair | Bay number, roughly how tall, stuck open or stuck closed | If it coils into a barrel instead of sliding on ceiling tracks, it's a rolling door |
| Door made of interlocking steel slats that coils into a drum above the opening | Rolling steel or coiling door | Commercial roll-up & rolling-steel door repair | Whether it's jammed in the side guides or won't lift | If it has a release device or closes on the fire alarm, it's fire-rated |
| Rolling door with a release mechanism or fusible link, often over an opening in a fire wall | Rolling fire door | Rolling fire door drop testing & repair | Whether it has dropped and won't reset | Needs a trained fire door technician, not general door repair |
| Fast fabric or rigid door that opens in a few seconds, often at a cooler or freezer | High-speed door | High-speed & cold-storage door repair | Whether the bottom bar has come out of the guides | No counterbalance springs — it is not a sectional door |
| Steel plate built into the dock floor that raises and lowers, with a lip that folds out | Installed dock leveler | Dock leveler repair | Won't raise, won't stay down, or the lip won't extend | If it's a loose plate you set in place by hand, it's a dock plate |
| Loose metal plate with handholds, lifted into position between dock and trailer | Portable dock plate or dock board | Dock plate & dock board section | What's bent, cracked or missing | Different equipment, different standard, usually a different answer |
| Short leveler bolted to the face of the dock with a hinged lip | Edge-of-dock leveler — a small leveler that mounts on the dock face instead of sitting in a pit | Dock leveler repair | Whether the lip folds out and holds | Still a leveler, not a plate |
| Foam or fabric pads around the door opening that the trailer presses against | Dock seal | Dock seal, shelter & bumper repair | What's torn and on which side | — |
| Fabric canopy on a frame that the trailer backs into | Dock shelter | Dock seal, shelter & bumper repair | What's damaged and whether the frame is bent | — |
| Rubber blocks bolted to the dock face below the opening | Dock bumpers | Dock bumper section | Whether steel is now hitting steel | — |
| Hook or arm at the base of the dock that grabs the trailer, with red and green lights inside and out | Vehicle restraint or dock lock — a powered device that holds the trailer against the dock | Trailer restraint & dock lock repair | Which light is showing, and whether it will release | — |
| Motor, chains, wall box or photo eyes that run a door | Commercial operator, controls and sensors | Operator section | Whether the door runs at all | Stays with the door it controls |
Can't tell which one it is? Call (385) 325-7138 and describe what you can see from where you're standing.
Nameplates you may see on Charleston dock and door equipment
Sometimes there's a name on the unit. On dock levelers you may see Rite-Hite, Kelley, Serco, Blue Giant, Nordock or Pentalift. On commercial doors you may see Overhead Door, Clopay, Wayne Dalton, Raynor, Cornell or Cookson.
These are identification examples only. They are 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 safely from where you're standing. Never walk up to a damaged door, a broken spring, a raised leveler or a stuck restraint to read one. You can call without it.
What's it doing? Common dock and door failures
Most dock and door calls come down to a handful of failures: a door off its track or stuck part-way, a broken spring or cable, a leveler that won't raise or won't hold, a seal or bumper destroyed by a trailer, or a restraint that won't let a trailer go. You do not need to diagnose it. Describing what you can see is enough to get the right person and the right parts moving.
| What you're seeing | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| Door stuck part-way open | Tracks, rollers, cables, counterbalance, operator limits | A door stopped part-way can be holding weight in a way it wasn't designed to | "Bay 4, stuck about halfway, won't move either direction" |
| Door visibly off track after an impact | Track alignment, rollers, hinges, panels, frame | Forcing an off-track door usually makes the repair bigger | "Forklift hit bay 2, door is off the track on the left side" |
| 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, now the door won't lift at all" |
| Door closes then immediately reverses | Photo eyes, safety edge, operator settings, travel limits | Often the safety system doing its job rather than failing | "Closes about a foot then goes back up every time" |
| Operator runs but the door doesn't move | Drive coupling, chain, shaft, clutch, operator | Running an operator against a stuck door can damage more | "Motor runs, nothing happens" |
| Leveler won't raise | Hydraulic or spring mechanism, controls, power, deck | A dock out of service backs trailers up fast | "Leveler at bay 7 won't come up" |
| Leveler won't stay level under a loaded lift truck | Hold-down, hydraulics, springs, deck structure | A leveler that drops under load is a serious hazard | "It comes up, then sinks when the forklift goes on it" |
| Lip won't extend or won't retract | Lip assembly, hinge, lip mechanism | Without the lip there's no bridge to the trailer | "Deck raises but the lip won't fold out" |
| Dock seal or shelter torn open | Seal pads, head curtain, shelter frame, mounting | Open seals cost conditioned air and let weather in | "Trailer tore the left seal off bay 6" |
| Bumpers missing or crushed | Bumper condition, mounting, dock face | Without bumpers, trailers hit the building and the equipment above | "Bumpers are gone on bay 3, steel is hitting steel" |
| Restraint won't release the trailer, or the lights disagree | Restraint mechanism, controls, light box, interlocks | A trailer held at the dock stops the bay and the driver | "Dock lock won't release, outside light still red" |
| Rolling fire door dropped and won't reset | Release device, counterbalance, guides, alarm interface | Resetting a fire door is a qualified-technician job | "Fire door came down last night and won't go back up" |
While you're waiting, keep it simple. Keep people and lift trucks clear of the opening and clear of anything under tension. Don't force the equipment. Follow your facility's own process for taking that bay out of use. Nobody should be examining, adjusting or releasing a spring, cable, hydraulic or restraint — that's what a qualified provider is for.
Call (385) 325-7138 and say the bay number and what it's doing.
Need emergency dock door repair in Charleston?
If a door is stuck open, a dock is down, or a trailer can't be released, say that in your first sentence when you call. What moves things along is a clear description of the problem, the equipment and how to get to it. Lead with the facility address, the bay number, and what stopped working.
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.
What to report right now
- Facility address
- Bay or door number
- What the equipment is doing — not what you think is wrong
- Whether the building is open to the outside
- Whether the bay is out of service
- A callback number
- Anything about getting in: gate code, dock hours, escort, security clearance
Keeping people clear while you wait
Keep people and powered equipment away from the opening and away from anything under tension. Don't force the door or the leveler. Follow your facility's existing process for taking the affected bay out of use.
Don't send anyone to look at a broken spring, a cable, a raised leveler or a stuck restraint. Not to read a label, not to take a photo, not to "just check." You can describe the problem without any of that.
If the dock is down, say so first.
What we cover — and what we don't
Buildings and equipment we take calls about
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 facility doesn't have to be a giant distribution center. A four-bay fleet garage counts.
The equipment: loading-dock equipment, and building-mounted commercial garage, overhead, sectional, rolling-steel, roll-up and high-speed doors.
What we don't cover
- Residential garages. A house garage door is a different trade with different parts.
- Boat docks, piers, seawalls and boat lifts. Charleston is a waterfront city, so "dock repair" means two completely different trades here. If you need pier, seawall or boat-lift work, you want a marine dock contractor.
- Truck and trailer cargo doors. The door on the back of the trailer isn't ours. The door on the building is.
- Pedestrian storefront, automatic-entry, glass and hollow-metal walk-through doors, along with their locks and closers.
- Parts-only requests. We take service calls, not parts orders.
- Structural concrete, pit and slab work. If the dock face or the pit itself is failing, that's a different contractor.
What happens when you call (385) 325-7138?
Three steps. No forms, no accounts, no quote funnel.
- You describe the problem. Facility address, bay or door number, what the equipment is doing. You do not need a model number, a photo, a measurement or a diagnosis.
- We route your call. The request is shared with an independent commercial dock-and-door repair company. Uptime Dock & Door is not the repair contractor. We don't price, schedule or perform the work.
- That company confirms everything with you directly — address and access, scope, availability, price, scheduling, and its own contract, work and warranty terms.
Example wording — this is enough to start: "Bay 4 is stuck halfway open at our warehouse in Charleston, and I can give you the address."
That's an example of what a first sentence can sound like, not a script and not a real job. Say it however you say it.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Independent service-request website. Calls may be shared with an independent commercial dock-and-door repair company. That provider confirms availability, scope, pricing, and service terms.
Do I need to know the brand or model before I call?
No. The facility location, the bay number, and "it's stuck open" are enough to start.
If a nameplate happens to be visible from where you're standing, it helps a little. But nobody should go looking for one, and no call gets turned away for not having it.
What's useful to have on the call — if you already have it
None of this is required. If you have none of it, call anyway. It's help, not homework.
- Roughly how wide and how tall the door is
- Whether the opening is heated, cooled or refrigerated
- Whether the door is manual or powered
- Roughly how old the equipment is
- What changed right before it failed — an impact, a power event, a storm
- How someone gets on site: gate code, dock hours, escort, clearance
- Who authorizes the work
What does dock or door repair cost in Charleston?
Nobody can price your repair from a web page, and that includes us.
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.
Ask about the shape of the price, not just the number
Companies price commercial work in different ways, and the words matter:
- A call-out or diagnostic fee pays for someone to come look. Ask whether it's credited toward the repair if you go ahead.
- A starting price is the floor for a job type. Ask what's included at that floor and what pushes it up.
- A scoped fixed price covers a defined list of work. Ask what happens if they open it up and find more.
- An estimate is a considered guess before the work is fully known.
- A final quote is a commitment to a number for a defined scope.
Worth asking on any commercial door or dock job:
- Is this visit diagnostic, or is the repair authorized up front?
- How is a diagnostic or trip charge handled if the repair goes ahead?
- Are the parts in stock, and what's the lead time if they aren't?
- Is this a temporary fix to get the bay running, or the permanent repair?
- If after-hours work is involved, how is that charged?
- Can I see the scope in writing before work starts?
What actually drives the number
| Driver | Why it moves the price | What to have ready |
|---|---|---|
| Equipment type and mechanism | A hydraulic leveler, a spring-counterbalanced sectional and a coiling door are different jobs with different parts | What you can see, or the bay number |
| Door size and gauge | Bigger and heavier means more material, more labor and sometimes more people | Rough width and height |
| Springs, cables and counterbalance condition | The highest-hazard part of a door, and the part that decides whether it's a component fix or a rebuild | Whether you heard a bang |
| Operator type and age | Older operators can need control or safety-system work alongside the repair | Whether it's powered, and roughly how old |
| Leveler mechanism and capacity | Hydraulic, mechanical and air-powered levelers fail differently and carry different parts | Which one you have, if you know |
| Parts availability and lead time | A stocked part and a factory-order part are different timelines and different prices | Nameplate, only if it's safely visible |
| Access and working height | Tight docks, live traffic and high openings 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 usually priced differently | When you need it usable |
| Wind rating or fire rating on the opening | A rated opening brings documentation and specific products into the job | Whether the door has a label |
Uptime does not set, see, or take part in pricing. That conversation is between your facility and the repair company.
Call (385) 325-7138 to describe the equipment and the fault.
Repair or replace the dock equipment?
There's no age at which equipment automatically gets replaced. There are factors, and you can weigh them yourself.
- Is the same fault coming back? Three visits for the same problem usually means something underneath hasn't been addressed.
- Are parts still available? When a part goes to factory-order or obsolete, the math changes.
- Is the failure the equipment or the building? A leveler sitting in a failing pit, or a door hung in a bent frame, is a different problem than the equipment itself.
- Has the opening's requirement changed? If a door now has to meet a wind rating or a fire rating, replacement brings documentation with it. See commercial door installation and rolling fire doors.
- How hard is the bay worked? A door cycling two hundred times a day and one cycling twice a week wear out very differently.
For the leveler-specific version of this question, see dock leveler repair. Uptime's national reference page on dock leveler repair vs. replace goes deeper on the equipment side.
Before you hire in Charleston: what actually applies to this work
Three questions are worth asking before you authorize commercial door or dock work in South Carolina: what license the company holds, who issues the permit for your parcel, and — if a door is being replaced — what the opening has to be built to withstand. Here's where each answer actually comes from. We checked each of these ourselves on the dates shown.
We can't tell you whether a permit, license or code applies to your door. Nobody can from a web page. The rule, where to check it, and what to ask are the honest ceiling. The provider and the issuing office confirm the rest.
| The question | What we verified | Where to check it | What to ask the company |
|---|---|---|---|
| What license should they hold? | South Carolina law says no one may do contracting work "for which the total cost of construction is greater than ten thousand dollars for general contracting or greater than ten thousand dollars for mechanical contracting" without a license. Plenty of single-door and single-leveler repairs fall under that. A multi-bay replacement usually doesn't. | SC Code §40-11-30 · checked 2026-09-21 | "What South Carolina license are you working under for this scope?" |
| Is there a "door" license in SC? | Not by that name. South Carolina has no classification for overhead doors, garage doors or dock equipment. What it does have: Building, covering "commercial, industrial, institutional, modular, and all other types of building construction"; and a Nonstructural Renovation subclassification that expressly includes "window and door installation." Miscellaneous Metals covers "installation, repair, or alteration of metal or composite shapes, tubing, pipes and bars." Classification follows the scope of the job, not the trade name. | SC Code §40-11-410 · checked 2026-09-21 | "Which classification covers this particular scope?" |
| Who handles the operator wiring? | South Carolina is specific: "A contract that contains electrical work above fifty volts must be performed by a contractor licensed under this subclassification." So replacing a door and wiring a new operator can fall under two different licenses. | SC Code §40-11-410 · checked 2026-09-21 | "Who's licensed for the electrical, and is that the same company?" |
| Is there an easy check? | Two. South Carolina publishes a contractor license lookup. And on permitted work, the permit itself is a license check: a building official "shall refuse to issue a permit for an undertaking which would classify the applicant as a contractor under this chapter unless the applicant has furnished evidence that the applicant is either licensed as required by this chapter or exempt." | SC Contractor's Licensing Board and its contractor lookup · SC Code §40-11-350 · checked 2026-09-21 | "What name and license number will be on the permit?" |
| Who issues the permit for this parcel? | Ten separate offices operate across the three counties, and no jurisdiction here publishes a rule specifically about commercial doors. What they publish is broad alteration language. North Charleston's reaches anyone who would "erect, construct, add, alter, demolish, excavate around, alter grading of, or move any structure" without a permit. Mount Pleasant's says outright that a permit is required to "erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system." | See the Charleston service area for the office, phone and portal in each jurisdiction · checked 2026-09-21 | "Which office issues this permit, and who's pulling it?" |
| Does the door need a wind rating? | South Carolina adopted the 2021 code family effective January 1, 2023 — and made no wind-related modification to the building code at all. The state's 2021 changes to the International Building Code run to eleven items, none of which touch wind, ASCE 7, windborne debris or opening protection. So unmodified code applies. Separately, the state's own county wind maps are residential-only by their own wording and shouldn't be used for a warehouse. A design pressure can't be read off a wind speed either — the door industry lists eleven site-specific variables that go into it. | SC Building Codes Council · DASMA TDS #155v · checked 2026-09-21. Full detail on commercial door installation | "What design pressure does this opening have to meet, and who confirmed it?" |
| Is it a fire-rated rolling door? | South Carolina doesn't adopt NFPA 80 by name — it arrives as a referenced standard inside the adopted 2021 South Carolina Fire and Building Codes. NFPA 80 requires rolling fire door inspection and testing by a trained rolling steel fire door systems technician. The door industry's own guidance is a drop test not less than annually, with records kept at least three years. | Full detail on rolling fire door drop testing & repair · checked 2026-09-21 | "Is your technician trained on rolling steel fire doors, and what document do I get?" |
Whether any of this applies to your actual job is determined by the company doing the work and the office that issues the permit — not by this page.
Where we take calls across the Charleston area
Call about commercial dock and building-mounted door work at facilities in Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, Ladson, Hanahan, Moncks Corner and other Berkeley, Charleston and Dorchester County communities. The independent company that accepts a request confirms the facility address, equipment scope, and availability.
The three counties are the Charleston–North Charleston, SC Metropolitan Statistical Area as delineated by the federal government.
Three things about Charleston geography that trip people up
These aren't trivia. Each one changes who you call about a permit.
North Charleston, Summerville and Ladson each sit in all three counties. Berkeley County's own site says Summerville is "Located in Berkeley, Dorchester and Charleston counties." Ladson isn't even incorporated. So a mailing address doesn't tell you who issues your permit. The parcel does.
"Ridgeville" means two different places. The Town of Ridgeville is in Dorchester County. The Volvo plant at Camp Hall that carries a Ridgeville address is in Berkeley County — Volvo's own site says "Ridgeville, Berkeley County, South Carolina." If someone tells you your Camp Hall facility is permitted by Dorchester County, check.
Daniel Island is a Berkeley County address. Confirm which office permits your parcel rather than assuming it's the county.

Call (385) 325-7138 with the facility address.
Can I set up planned maintenance instead of waiting for the next failure?
Yes, and it's a different conversation from an emergency call. Planned maintenance is scheduled, scoped and budgeted; a repair call is a response to a failure. The door industry's own guidance is that a trained door systems technician should inspect and maintain "at least annually or per the door manufacturer's recommendations," with electric doors evaluated quarterly.
Worth knowing: that guidance doesn't publish a fixed interval table. It defers to the door manufacturer. So annual is a floor, not a schedule — and a door cycling hundreds of times a day is a different conversation from one that opens twice a week.
Dock equipment maintenance is its own scope, not a subsection of door maintenance. A leveler, a restraint and a set of seals get inspected for different things than a sectional door does.
Commercial garage & overhead door maintenance covers the door side and explains where the dock side sits.
Call (385) 325-7138 about planned maintenance.

Questions Charleston facility managers ask
Do you work on loading docks at warehouses, or just garage doors? Both. The dock side means levelers, seals, shelters, bumpers, plates and restraints. The door side means sectional, overhead, roll-up, rolling-steel, high-speed and fire-rated doors. Most Charleston calls involve one or the other, and plenty involve both at the same bay.
Is a dock leveler the same thing as a dock plate? No, and it matters. A leveler is built into the dock and raises and lowers in place. A dock plate is a portable piece of equipment you lift into position between dock and trailer. They fall under different standards and the repair answer is usually different — a damaged portable plate normally comes out of service rather than getting fixed. See dock levelers and dock plates and boards.
Do you handle boat docks or piers? No. That's marine work — a different trade entirely. This site is commercial loading docks and building-mounted doors.
What do I need to know before I call? The facility address, the bay or door number, and what the equipment is doing. That's it. No model number, no measurement, no photo, no diagnosis.
Do you cover Summerville, Ladson and Moncks Corner? Yes, along with the rest of Berkeley, Charleston and Dorchester counties. Worth knowing that Summerville and Ladson each sit in all three counties, which is why your permit office depends on the parcel rather than the mailing address.
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 route your call. We don't repair equipment, send technicians, or set prices.
Can you tell me what it will cost? No, and neither can anyone else from a web page. What we can do is explain what drives the number and what to ask before you authorize work — that's in the cost section above.
Does my rolling fire door need an annual drop test? If it's a labeled fire door assembly, the standard requires periodic inspection and testing, and the door industry's guidance is not less than annually by a trained rolling steel fire door systems technician. An ordinary rolling service door is not automatically a fire door. Full answer here.
Do I need a permit to replace a commercial door in Charleston? No jurisdiction in this metro publishes a rule specifically about commercial doors. What they publish is broad alteration language that generally reaches replacement, and a new powered operator brings electrical work with it. The only reliable answer for your parcel comes from the office that issues the permit. Who that is, by town.
Call about the bay that's down
You don't need to know what it's called. You don't need a model number. You need a phone.
Tell us the facility address, the bay number, and what stopped working.
Call to describe the problem—if the door is stuck open or the dock is down, say so first. If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
