Is this a commercial overhead door?
A commercial sectional overhead door is a door made of hinged panels that rides up side tracks toward the ceiling. It's usually bigger and heavier than a home garage door, and it usually runs on a motor, called an opener or operator. Loading docks, fleet garages, auto-service bays and warehouses use them. A roll-up door is a different kind of door, with its own page.
Warehouse door, industrial door, bay door, loading door, garage door: people use all of these names. They describe the building more than the door. If the door is made of panels that ride tracks, it belongs on this page.

|---|---|---|
| Panels on side tracks that curve back overhead | Sectional overhead door | This page |
| Tracks that run straight up the wall instead of back along the ceiling | Sectional door with high-lift or vertical-lift track | This page |
| Steel slats that coil onto a drum above the opening | Rolling steel / roll-up door | Roll-up door repair |

What's wrong with it?
Describe what the door is doing. A qualified provider checks the springs, cables, tracks, rollers, panels and opener on site. The table shows why each part matters. It doesn't tell you how to fix it.
| What you notice | What a qualified provider may inspect | Why it matters | How to report it |
|---|---|---|---|
| A bang, then the door is very heavy or won't lift | Torsion or extension springs, cables, drums | Springs store energy. A broken one can let the door drop. | "Heard a bang. The door won't lift." |
| Door hangs crooked, one side lower | Cables, drums, rollers, track alignment | It can close unevenly or jam | "The door hangs crooked." |
| A panel bent or cracked after a hit | Panels, struts, hinges | It can bind or come off the track | "A forklift hit the door at bay 3." |
| Rollers out of the track | Tracks, rollers, brackets | The door can fall or jam | "It's off track at the top left." |
| The opener runs, but the door doesn't move | Opener, drive, disconnect, spring balance | The door may be out of balance | "The motor runs, but the door stays put." |
| The door goes back up before it closes | Photo-eye sensors, safety edges, travel limits, controls | These are the parts that keep the door from closing on someone | "It reverses near the floor." |
| Grinding, shaking, or noisy travel | Rollers, hinges, springs | Wear shows up before a failure | "It grinds when it opens." |
| Weather coming in at the bottom | Bottom seal, bottom panel | Heat and cooling loss | "There's a gap under the door." |
A torsion spring is the big coiled spring on a bar above the door. It balances the door's weight. Keep people clear of any door with a broken spring or cable, and leave it where it is.
Describe what the door is doing.
A broken spring or cable: what to do now
Leave the door where it is, keep people and forklifts clear, and call. The springs and cables on a commercial overhead door hold a lot of stored energy. Adjusting or replacing them is work for a qualified provider.
A commercial door spring job isn't like a home garage door spring. The doors are bigger and heavier. They often run many more open-and-close cycles a day. The springs are sized to that door and that use. That's why the provider asks about the door's size and how often it runs.
Helpful to say on the call, if you know it:
- About how wide and tall the door is
- Which side the bang or the loose cable is on
- Whether the door is open, closed, or stuck partway
Spring or cable broke? Say so first.
Opener, operator and controls
A commercial door opener is part of the door's safety system. UL 325 is the standard for door operators. The door industry's guidance for commercial openers, DASMA TDS 382, calls for testing the photo-eye sensors every month.
Photo-eyes, edges and reversing
Photo-eyes are the small sensors near the bottom of the tracks. Safety edges are the strips on the bottom of the door. They tell the opener to stop or reverse if something is in the way. If the door keeps reversing, report that. Don't tape over or move the sensors.
Push-button stations and controls
OSHA's lockout rule says push buttons and selector switches are not energy-isolating devices (29 CFR 1910.147). That's one reason servicing is left to trained providers. Pressing "stop" doesn't make a door safe to work on.
Opener wiring
Connecticut has no separate license for door openers. Ask whether the job involves line-voltage electrical work, and who holds the Connecticut electrical license.
Need emergency commercial garage door repair in Hartford?

While you wait:
- Keep people and traffic clear of the doorway.
- Don't force the door, pull on cables, or run the opener over and over.
- Follow your facility's normal process for taking the bay out of use.
- If the building can't be closed up, use your normal security plan.

What Uptime covers for overhead doors — and what it doesn't
Covered: commercial sectional overhead doors at commercial buildings; the provider confirms the size and equipment it can handle. That includes springs, cables, drums, tracks, rollers, panels, window panels, bottom seals, openers and controls. That covers warehouses, plants, fleet garages, auto-service bays, self-storage, cold storage and other commercial sites.
Not covered:
- Home garage doors
- Roll-up doors on trucks and trailers
- Storefront, glass and walk-through doors, and their locks and closers
- Parts-only orders
- Structural concrete and framing around the opening
For a home garage door, a residential garage-door company is the right call.
What happens after you call
- Call (385) 325-7138 and describe the door. Say what it's doing, which bay, and the building's town and address.
- Your call may be shared with an independent provider. Uptime doesn't repair doors or send technicians. How Uptime works.
- The provider confirms the details. Availability, scope, price, schedule, and its own work and warranty terms come from that company. Who we are and how we're paid.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Useful to have on the call (optional)
You can call without any of this.
- The door number
- About how wide and tall it is, if you know
- Whether it's a panel door or a roll-up door (the table above helps)
- The opener brand, if you already know it or can see it from a safe spot
- Whether the door is insulated
- When it failed, and what happened just before
Brand names you might see on a door: Overhead Door, Clopay, Wayne Dalton, Raynor, Haas. These help describe it. They don't mean any provider is an authorized dealer.
What decides the price, and when replacement makes sense
We can't quote your 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 whether you're hearing a trip or diagnostic charge, a starting price, an estimate, or a final quote for a set scope of work. Then ask what it includes.
| Cost driver | Why it moves the price | What to ask |
|---|---|---|
| Door size and weight | Bigger doors need bigger springs, cables and hardware | "Is this door size something you handle?" |
| Springs | Type, count and cycle rating change the parts | "Are you matching the springs to how often this door runs?" |
| Cables and drums | Often replaced with a broken spring | "Are cables included?" |
| Replacing panels | Matching panels depends on the door's maker and age | "Can the panel be matched, or does more of the door change?" |
| Opener repair vs. replacement | A new opener adds parts, setup and wiring | "Does this include electrical work, and who's licensed for it?" |
| Access and height | High doors and blocked bays take longer | "What should we clear first?" |
| Trip or diagnostic charge | Many companies charge to come out | "Is there a trip charge, and does it go toward the repair?" |
| Timing | Nights and weekends may cost more | "Do after-hours rates apply?" |
| Replacement permit | Replacing a door can involve a town building permit | "Will you check with the town about a permit?" |
Repair or replace?
Replacement comes up when damage covers more than a panel or two, when parts can't be matched, when the door keeps failing, or when the building's needs changed. That includes insulation, more trips a day, or a different opening. If it's heading that way, see commercial garage door installation & replacement.

Connecticut rules for overhead door work
Connecticut doesn't license overhead door work as its own trade. Electrical work on an opener falls under the state's electrical licenses. A Home Improvement Contractor number is a residential registration. Permits come from the town. Ordinary repairs don't need a permit under the state code. That changes when the work touches wiring, structure or exits.
| Question | What's true in Connecticut | Where to check |
|---|---|---|
| Door license? | None. Doors aren't on the state's list of trade licenses. | CT DCP trade licenses |
| Opener wiring? | Electrical licenses run from E-1/E-2 to limited classes. There's no door-opener license. | DCP electrical license types · License lookup |
| Home Improvement Contractor number? | It covers private homes, up to six units. It isn't a commercial credential. | C.G.S. § 20-419 |
| Permit for a repair? | Ordinary repairs need no application, except work on wiring, structural supports, or required exits (§ 105.2.2). Door replacement isn't on the exempt list (§ 105.2). | 2022 CT State Building Code |
| Who issues permits? | The town or city, not a county | Your town's building department |
| Which OSHA? | Federal OSHA for private-sector workplaces | OSHA: Connecticut |
The provider and the town decide what applies to your door.

Questions about commercial overhead door repair
Will a residential garage-door company work on our commercial door?
Some companies do both. Ask whether they handle your door's size and weight, and the opener it runs on.
Is it safe to open a door with a broken spring?
No. Leave it where it is, keep people clear, and call.
Why does my door go back up before it closes?
Several causes are possible, including photo-eyes, safety edges, travel limits and controls. The provider checks them. Don't move or cover the sensors.
Do I need a permit to repair a commercial overhead door in Connecticut?
Ordinary repairs don't need a permit application under the state code. Work on wiring, structural supports or exits is different, and door replacement isn't on the exempt list. The town decides for your job.
Does an opener problem need an electrician?
It depends on what's wrong. Ask whether the job involves line-voltage electrical work and who holds the Connecticut electrical license.
