Dock, overhead, or roll-up? Start here

Start with these three equipment groups. Pick the one that sounds like your bay.

Loading dock and dock doors. A loading dock door, often called the bay door, closes the truck-bay opening. This includes the tall sectional doors at your truck bays, plus the levelers, seals, bumpers, lights, and restraints around them. That is what this page covers. Keep reading.

Commercial garage and overhead doors. Drive-in doors, service bays, and warehouse openings. Springs, cables, tracks, rollers, panels, openers. → Commercial garage and overhead door repair in Jacksonville

Commercial roll-up and rolling steel doors. Coiling steel curtains that jam, hang crooked, or won't secure the building. → Commercial roll-up and rolling steel door repair in Jacksonville

Facilities across the five-county Jacksonville metro can call: Duval, Clay, Nassau, St. Johns, and Baker. That covers the Westside and Cecil Commerce Center corridor, the Northside and Imeson area, Southside, the Beaches, Orange Park, Yulee, Fernandina Beach, and St. Augustine. → See the full Jacksonville service area

Not sure which of the three is yours? That is normal, and it is a fine reason to call.

Find your equipment (and what to say about it)

A loading dock is a system, not one part. The door closes the opening. The leveler bridges the gap to the trailer. The bumpers take the hit. The restraint holds the trailer while a forklift is inside it. Any one of them can shut a bay down.

You do not have to name the part. But if you can match what you see to a row below, the call gets shorter.

Tall door at a truck bay, made of joined panels with rollers in vertical tracksSectional dock doorThis pageBay number, whether it moves at all, whether it hangs crookedNot a roll-up. A roll-up has no hinged panels

One more thing worth saying plainly: a sectional overhead door and a dock door are often the same door. "Dock" describes where the opening is and how it gets used. "Sectional" describes how the door is built. A warehouse can have the same panel-and-track door at a truck bay and at a drive-in bay. The dock page addresses the loading-bay system; the overhead-door page goes deeper into the door mechanism, including drive-in and service-bay openings.

You do not need to fill in a single column to call. The facility address, the bay or door number, and "it's stuck open" are enough.

Call and describe the door problem in your own words.

What's happening at the dock?

These symptoms help describe a dock or door failure. Describing what you see beats guessing at the part, and it is safer. Nobody needs you to open a cover or climb anything to answer a question.

The middle column is what a qualified provider may look at. It is not a diagnosis of your equipment.

What you're seeing or hearingWhat a qualified provider may inspectWhy it mattersHow to report it
Door stuck open or stopped partwayCounterbalance springs, cables and drums, track alignment, operator limitsA door held up by damaged counterbalance can come down without warning"Bay 6 stopped about four feet up and won't move either way"
Loud bang, then the door won't liftTorsion spring, cable, shaft, drumA torsion spring is a tightly wound spring above the door that carries the door's weight. A broken one can leave the door without its intended counterbalance"There was a bang, now it won't lift"
Door hangs crooked or came off track after a hitRollers, hinges, track, panel, jamb, and whether the counterbalance is still loadedA forklift strike can leave damage you won't see until the next cycle"A reach truck clipped it, it's crooked now"
Operator runs but the door doesn't moveDrive, gear, chain or coupling, and the operator's own safetiesRunning it again and again turns a small failure into a big one"Motor runs, door doesn't move"
Door closes then reverses, or won't close at allPhoto-eyes, bottom sensing edge, limits, anything in the pathThose are entrapment-protection devices. Switching one off is not a repair"It comes down a foot and goes back up"
Leveler won't raise, lower, or put its lip outPump, motor, cylinder, hoses on a hydraulic unit; main spring and hold-down on a mechanical one; pit conditionA leveler that won't store can also keep the door from closing"The leveler goes up but won't come down onto the trailer"
Leveler feels loose, drops, or bangs under a forkliftStructure, hold-down, lip hardware, pit and supportsA leveler carries loaded lift trucks. "Feels off" is reason enough to take the bay out of use"It kicks the forklift when we cross"
Restraint won't engage or won't release, trailer stuckHook or arm mechanism, controls, bay lights and interlockFreeing a trailer that a restraint is holding is not a job for untrained staff"The lock won't release and the driver is waiting"
Torn dock seal or shelterFabric, pads, head curtain, mountingGaps let weather, rain, pests, and cold air through. Loose fabric catches trailers and tears worse"The left side pad is ripped off"
Crushed or missing bumpersBumper condition and mounting, dock face, leveler lipWithout bumpers, trailers hit the dock face and the leveler lip directly"Two bumpers are gone on the north bays"
Rolling steel door jammed, curtain out of the guidesCurtain, slats, endlocks, guides, bottom bar, barrel, counterbalanceA curtain out of its guides can come out of the opening"The curtain popped out of the track on the right side"
Fire door dropped closed by itselfRelease mechanism, governor, fusible links or detection tie-in, resetResetting a fire door is a documented job for a trained technician, not a push"The fire door came down and we can't get it back up"

While a bay is down: keep people and equipment clear, don't force the door, and don't keep running the operator to see if it works. Follow your facility's normal process for taking the bay out of service. Don't walk up to a damaged door, a broken spring, a raised leveler, or a stuck restraint to get a closer look.

If the dock is down, say so first.

Need emergency dock door repair in Jacksonville?

Call (385) 325-7138 and lead with the urgent part: which bay, what it's doing, and whether a trailer is trapped or the building is open to the outside. Those three facts are what an independent repair company needs to judge how fast it can get there and what to bring. Uptime does not dispatch technicians or promise arrival times. The provider that takes the work confirms its own availability.

What to report first

  • The facility address
  • The bay or door number
  • What the equipment is doing, or not doing
  • Whether a trailer is at the dock, or trapped
  • Whether the opening is exposed to the outside overnight
  • Any site access, check-in, or safety rules a visitor has to follow
  • The brand or model only if you already know it or can read it from where you're standing

What to do while the bay is down

Keep people and lift trucks clear of the opening. Don't force the door and don't keep cycling the operator. Don't try to free a restraint or drag a damaged portable plate out of the way. Take the bay out of service the way your facility normally does it, and move trailer work to another position if you have one.

That's it. No resets, no inspections, nothing that puts a person near the equipment.

If you reach voicemail

If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

Call to describe the problem—if the door is stuck open or the dock is down, say so first.

What we cover, and what we don't

This is the part that saves everyone a wasted trip. Read the third list carefully.

Facilities

Warehouses and distribution centers. Manufacturing plants. Cold storage. Food and beverage plants. Auto-service bays and fleet garages. Workshops and light industrial shops. Commercial self-storage. Municipal, institutional, and other commercial buildings.

A facility does not have to be a giant distribution center. A four-bay fleet garage off Cassat Avenue counts.

Equipment

Loading-dock equipment and building-mounted commercial doors. Sectional dock doors. Commercial garage and overhead doors. Rolling steel, coiling, and roll-up doors. High-speed fabric and rigid doors. Fire-rated rolling doors. Dock levelers, including hydraulic, mechanical, air-powered, edge-of-dock, and vertical-storing. Dock plates and boards. Seals and shelters. Bumpers. Dock lights. Wheel chocks. Vehicle and trailer restraints. The operators, controls, sensors, and bay lights that run all of it.

Not covered

  • Residential garages
  • Boat docks, boat lifts, and marine dock structures
  • Truck and trailer cargo doors
  • Pedestrian storefront, automatic-entry, glass, and hollow-metal walk-through doors, with their locks and closers
  • Parts-only orders
  • Structural concrete, pit, and slab work

If what's broken is on that list, say so on the call. You'll get told plainly that it isn't a fit instead of having someone show up who can't help.

What happens when you call

Three steps. No form, no photo upload, no quote funnel.

1. You describe it. Facility address, bay or door number, and what stopped working. You do not need a model number, a measurement, a photo, or a guess at the cause.

2. We share the request. Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair. Calls may be shared with an independent commercial dock-and-door repair company.

3. That company takes it from there. The independent company that takes the work confirms the facility address, scope, availability, price, scheduling, and its own contract, work, and warranty terms.

Example wording (this is an example, not a real job and not a script):

"Bay 4 is stuck halfway open at our warehouse in Jacksonville, and I can give you the address."

One natural sentence. That's the whole bar.

Useful on the call, if you happen to have it

  • The bay or door number
  • Whether a trailer is at the dock
  • Roughly how tall and wide the opening is
  • Whether the leveler is hydraulic or mechanical, if that's already known
  • The brand off the data plate, only if you can see it without climbing, reaching into a pit, or walking up to damaged equipment
  • Site check-in requirements

You can call without any of it. This list is here to make the call shorter, not to give you homework.

Ready when you are.

What changes the price

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.

Prices in this trade come in a few different shapes, and they are not the same thing:

  • A call-out or diagnostic fee buys the trip and the look. It may or may not roll into the repair.
  • A starting price is the cheapest version of that job. Yours may not be the cheapest version.
  • A scoped fixed price covers named parts and named work. Anything outside the scope is extra.
  • An estimate is a provisional price based on the information and scope available.
  • A quote is a number someone will stand behind for the work described.

Ask which one you're being given. Then ask what's inside it.

What drives the costWhy it moves the priceWhat to ask before you authorize work
Diagnostic or service-call chargeA visit or diagnosis may carry a separate charge"Is there a service-call or diagnostic charge, and does it apply toward the repair if I approve the work?"
TravelA Macclenny or Hastings facility is a different trip than Imeson Road"Is travel billed separately, and how?"
After-hours and weekendsSome providers charge a premium, some don't"Is there an after-hours rate, and does it apply to my situation?"
Which piece failedA torn seal, a broken spring, and a failed hydraulic pump are three different jobs"What specifically failed, and what does the estimate cover?"
Parts and availabilityOn the truck, in a local warehouse, or ordered"Is the part on hand, and what's the lead time if it isn't?"
Door size, gauge, and buildA 12-by-14 insulated dock door is not a 9-foot service door"Does the quote match this opening's size and construction?"
Springs and counterbalanceWire size, length, and cycle rating change both cost and how long it lasts"What cycle life am I getting, and is the replacement matched to this door?"
Operators and controlsRepair or replace, and whether the safety devices come back working properly"Are the photo-eyes and sensing edge being repaired to work as intended, not bypassed?"
Leveler mechanismHydraulic, mechanical, and air units fail and price differently, and the pit matters"Is this a component repair or a rebuild, and what did you find in the pit?"
Product approval on a replacementA replacement exterior door needs the applicable statewide or accepted local approval for its configuration"What statewide or accepted local approval covers this door and opening?"
Fire ratingLabeled assemblies need original-manufacturer parts, a trained technician, and paperwork"Are the parts from the original manufacturer, and do I get the inspection and test record?"
Access and schedulingA live dock in shift hours, a trapped trailer, or a security check-in all change the job"Does the quote account for working around our shift schedule and site access?"
Repair versus replaceAt some point, repeat repairs cost more than a new door"What would you expect to spend on this door over the next year if we repair it instead?"

We don't publish a repair-price range for Jacksonville here. A published starting price or range is not a quote for your equipment, and a residential price does not establish a commercial repair price. Use the questions above to compare the actual scope and charges.

Call and describe the work you need looked at.

Before you hire in Jacksonville

Florida surprises people in three specific ways on commercial doors. Each row below gives you the rule, the office that answers it, and the one question that matters. The provider and the issuing office confirm what applies to your actual job. Nobody here can decide that for your door.

What to checkWhat's actually trueWhere to look it upThe question to ask
State licensingFlorida created a certified Garage Door Installation Specialty Contractor category, but Florida Statutes §489.113(6)(a) says certified specialty categories are voluntary statewide and do not create a mandatory licensing requirement. A mandatory statewide licensing requirement can only come from a specific statuteDBPR license verification"Which certification or registration covers this work?"
Local licensingLocal requirements must fit state law. §489.117(4)(a) limits which contractor categories local governments may require; electrical and structural work can also change the required scopeCity of Jacksonville contractor license and complaint search. In Nassau County the Building Official is also the Contractor Licensing Official. St. Johns County states that contractors must be licensed and registered with the county to obtain a permit or perform construction activity"Are you licensed or registered in the jurisdiction my facility is in?"
PermitsFBC §105.1 establishes the general permit rule; exceptions and the actual work matter. Ask about the specific component repair, full replacement, structural change, or electrical workCity of Jacksonville Building Inspection Division, 214 N. Hogan St., (904) 255-8500. Commercial applications go through JaxEPICS"Is this a repair or a replacement, does it need a permit, and who pulls it?"
Which officeJacksonville and Duval County are consolidated, but a mailing address does not identify the permit authority. For Jacksonville Beach, Atlantic Beach, Neptune Beach, or Baldwin, start with that municipality; in the surrounding counties, check whether the parcel is inside a city or townYour jurisdiction's building department. See the service area page for the list"Which office issues the permit for this address?"
Product approval on a replacementFlorida Statutes §553.842 covers approval of regulated building products, including exterior doors. Approval can be statewide or through a local method under §553.8425; a statewide FL number is not the only route. Duval is outside the High-Velocity Hurricane Zone, but the opening still needs the applicable wind-load and approval documentationFlorida Building Commission product approval search"What statewide FL approval or accepted local approval covers this exact door, configuration, and opening?"
Wind and design pressureApplicable wind-borne-debris and design-pressure requirements depend on the address, building, opening, and adopted code. Obtain the project criteria from the responsible design professional and confirm the submittal with the permit authority; a wind-speed lookup alone is not a door designYour jurisdiction's building department"What design pressure does this opening need?"
Fire-rated doorsDASMA guidance calls for rolling fire-door inspection and drop testing at installation and at least annually thereafter. Florida's Fire Prevention Code, 8th Edition (2023), effective December 31, 2023, adopts NFPA 1 and NFPA 101 (Florida 2021 Editions), and the local fire official enforces itYour local fire official. For a City of Jacksonville address, start with the City of Jacksonville's Fire and Rescue plan review process"Is this door fire-rated, when was it last drop tested, and is the technician trained on this type?"
Dock equipment safetyOSHA 29 CFR 1910.26 sets employer duties for portable and fixed dockboards: rated use, applicable run-off protection, securing portable devices, and preventing transport-vehicle movement. The rule includes specific exceptions and allows other safe handling means for portable units. The MHI/ANSI MH30 series addresses equipment categories; it does not replace OSHA's requirementsOSHA; MHI / ANSI"Does what you're proposing keep this equipment inside what OSHA requires of us?"

About permit fees: Jacksonville's published fee schedule has separate alteration and window/door-replacement lines under §320.409. The Building Inspection Division confirms which line, minimum, review, trade, and inspection charges apply to the actual scope. A permit fee is not an installed-door or repair price.

One last thing: if nobody can tell you whether a permit applies, that doesn't mean the work is exempt. It means the question hasn't been answered yet.

Call about a repair, and take these questions into the conversation.

Planned maintenance and replacement

Not every dock or door call is an emergency. Scheduled service and end-of-life replacement are different conversations with different questions, so they have their own pages.

Dock-side maintenance lives with the equipment: levelers on the leveler page, and seals, bumpers, lights, and restraints on the dock equipment page.

Call about planned maintenance or a replacement you're weighing.

Common questions about dock and door repair in Jacksonville

Do you handle the loading dock itself, or just the door?

The whole opening. The door, the leveler under it, and the seals, bumpers, lights, and restraints around it. Those are different pieces with different failure modes, so each has its own page here, but they are one call. The dock leveler page and the dock equipment page go deeper on the non-door parts. Structural concrete and pit work is the exception and is not covered.

Is a dock leveler the same thing as a dock plate?

No. An installed dock leveler is fixed in a pit or at the dock face; the portable dock plates and boards discussed here are moved into position. OSHA's dockboard definition includes both fixed and portable devices. Both need suitable rated use and vehicle-movement controls; the portable-device page explains its additional handling and securing questions.

Do I have to know the brand or model before I call?

No. Facility address, bay number, and what stopped working is enough to start. If a data plate is readable from where you're already standing, great. Don't go get it. Don't climb, don't reach into a pit, and don't walk up to a damaged door or a raised leveler for a model number.

Do you work on residential garage doors or boat docks?

Neither. This is commercial and industrial equipment only. Residential garages, boat docks, boat lifts, and marine dock structures are all outside the scope, along with truck and trailer cargo doors, pedestrian storefront and walk-through doors with their locks and closers, parts-only orders, and structural concrete work. Say so on the call and you'll be told straight.

What should I do right now if a bay is stuck open?

Keep people and lift trucks clear. Don't force the door and don't keep running the operator. Take the bay out of service the way your facility normally does it. Then call and lead with the fact that the building is open and which bay it is. Don't try to prop, pry, reset, or inspect anything.

Who actually shows up? Is Uptime the repair company?

No. Uptime Dock & Door is an independent commercial service-request website for loading-dock and commercial door repair. Calls may be shared with an independent commercial dock-and-door repair company. That provider confirms availability, scope, pricing, and service terms, and that's who does the work and sends the invoice. More on how it works and about Uptime.

Do I need a permit to repair or replace a commercial door in Jacksonville?

It depends on the work and the address. The general permit rule has exceptions, so ask about the exact component repair, full replacement, structural alteration, and electrical scope. In the City of Jacksonville, start with the Building Inspection Division and JaxEPICS; elsewhere, confirm the parcel's city or county authority. A replacement exterior door needs the applicable product-approval documentation, which can follow a statewide or accepted local route.

Do you cover facilities outside Duval County?

Yes. Clay, Nassau, St. Johns, and Baker counties are all in the request area, and Orange Park, Yulee, Fernandina Beach, and St. Augustine have their own local pages. The service area page lists the communities by county. For an address near the edge, say where it is; the independent provider confirms whether it can take that location and job.

Tell us where the facility is and what stopped working. That's the whole first step. No model number, no measurement, no photo.
