Which doors does this page cover?
This page covers commercial sectional doors. They're made of panels that roll up a pair of tracks and sit flat overhead, balanced by springs. That includes the dock doors on a warehouse, the bay doors on an auto-service shop or fleet garage, and the overhead doors on workshops and plants. If the door winds up into a coil above the opening instead, it's a rolling door.
| If the door… | It's probably… | Go to |
|---|---|---|
| Rides up tracks in panels and sits overhead | A sectional or overhead door | You're on the right page |
| Winds onto a drum in a hood above the opening | A rolling steel or roll-up door | Roll-up & rolling-steel door repair |
| Opens very fast with a fabric, rubber or rigid curtain | A high-speed door | High-speed door repair |
| Has a fire label and closes by itself in an alarm | A rolling fire door | Rolling fire door testing & repair |
| Is being replaced, or you're adding a new one | A planned project | Installation & replacement |
What's wrong with the door?
Say what you see and hear. The table shows what a qualified technician may look at and why. It isn't a diagnosis, and nobody should walk up to a damaged door to check.
| What you notice | What a qualified provider may check | Why it matters | What to mention |
|---|---|---|---|
| A loud bang, then the door won't lift or feels far heavier | Torsion springs, cables and drums | These parts hold stored energy; don't run or lift the door | A bang, then it won't lift; door number |
| A cable loose or hanging | Cables, drums and bottom brackets | The door can drop unevenly | Which side the cable is on |
| Door crooked, one side low | Cables, drums and rollers | It can come out of its track | Which side is low |
| Off track after a forklift or trailer hit | Tracks, rollers, panels, hinges and struts | The door may be unstable | There was an impact; off track |
| Dented or cracked panels | Panels, struts and hinges | Replacing a section versus the door | How many panels are damaged |
| Opener runs but the door doesn't move | The opener drive and the door's balance | A door out of balance can overload the opener | Motor runs, door doesn't |
| Door goes down, then back up | Photo eyes, safety edge and limits | Those devices keep a closing door from hurting someone (UL 325) | Closes, then reverses |
| Door drifts down or won't stay open | Springs and balance | A falling door is a hazard | Won't stay open |
| Grinding, jerking or new noise | Rollers, hinges, bearings, track alignment | Wear often shows up before failure | The noise, and when it happens |
| Bottom seal torn, daylight at the edges | Bottom and perimeter seals | Heat loss, weather and pests | Which seal is torn |
Need emergency commercial garage door repair in Dayton?
Call (385) 325-7138 and say first that the door is stuck open or won't close. Keep people and vehicles clear. Don't keep running the opener or force the door by hand, and take the bay out of use the way your facility normally does. The independent company that takes the request confirms whether it can come, and when.
Report first: the address, the door number, whether it's stuck open or closed, anything under or in the opening, and whether the building is exposed to weather or theft.
What we don't promise: dispatch times, after-hours service or availability. We're a service-request line, not the repair company.
Example of what to say: "Dock door 7 at our warehouse in Dayton came off its track after a forklift hit it, and I can give you the address."
If the door won't close, say so first.
Broken springs and cables: what happens next
A commercial sectional door is balanced by torsion springs. Those are tightly wound steel springs on a bar above the door, and they store a lot of energy. Cables carry the door's weight down each side. When a spring or cable breaks, the door can suddenly feel very heavy or come down unevenly.
That's work for a trained technician with the right tools. It's not something to try on site.
What a technician typically looks at:
- Spring size and cycle rating. A cycle is one open and one close.
- The condition of the cables and drums
- How the door balances once the repair is done
Cycle count matters. A dock door that runs dozens of times a day wears springs faster than a door opened twice a day. Tell the company roughly how often the door runs, and ask whether higher-cycle springs make sense for it.
Openers, controls and safety sensors
The opener, also called the operator, is the motor unit that drives the door. It's covered here along with its wall controls, photo eyes and safety edges. Commercial door openers fall under UL 325, the safety standard for door operators. DASMA, the door industry association, says photo-eye sensors on commercial door openers should be tested monthly, with the beam no higher than six inches above the floor (TDS 382).
Common opener problems to report: it won't run; it hums; the door reverses; it stops partway; the wall button is dead; it quit after a power outage.
Replacing an opener. Ohio's building code requires approval to install or replace an electrical system (2024 Ohio Building Code §105.1). Ask the building office for your address whether your opener job needs a permit. Ohio requires a state electrical contractor license for electrical contracting. Inside Dayton, the electrical contractor must also be registered with the City.
The monthly photo-eye test. Follow the opener's manual, or ask the provider to show your staff how the test is done.
Opener names you may see: LiftMaster and Manaras-Opera make commercial openers. Door makers such as Overhead Door, Wayne Dalton, Raynor and Amarr list their own. These are label examples only, not a claim about who services what.
If the opener is part of a new door, see installation & replacement.

What helps on the call?
You can call with nothing but the address and what's wrong. If you already know any of these, they help:

Don't climb up to read a label or get close to a broken spring or cable to find a detail.
What affects the price?
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.
| What drives the price | What to ask |
|---|---|
| Trip or diagnostic fee | Is there one, and does it count toward the repair? |
| After-hours timing, if the company offers it | Does the rate change after hours? |
| Door size, steel gauge and insulation | Is the price for this door's actual size and build? |
| Spring count and cycle rating | How many springs, and what cycle rating? |
| Cables and drums | Are they included, or priced separately? |
| Number of damaged panels | Can single sections be replaced for this model? |
| Opener repair versus replacement | Is new wiring involved, and who pulls the permit? |
| Parts lead time | Are parts on hand, or ordered? |
| Access | Is a lift needed, or is a trailer in the way? |
Some companies publish prices. If you see one, ask whether it's a call-out fee, a starting price, a fixed price for a defined job, or an estimate. Then ask what's included.
Repair it, or replace it?
Repair usually makes sense when the damage is limited to a few parts or panels and those parts are still made for the door. Replacement comes up when replacement sections aren't available for the model, most of the door is damaged, springs and cables keep failing, or the door no longer fits how the opening is used. More trucks and new insulation needs are two common reasons.
For background, Uptime's national research covers commercial garage door repair versus replacement and published commercial garage door costs. That's national research, not a Dayton quote. For a new door, see installation & replacement.
With those questions ready, call to describe the job.
Dayton-area rules for overhead door work
Ohio has no state license for door contractors. New or replaced line-voltage opener wiring is electrical work, though, and that needs a licensed electrical contractor and an electrical permit. Inside Dayton, the electrical contractor must also be registered with the City.
| Rule | What it says | Where to check |
|---|---|---|
| State license | Ohio licenses HVAC, refrigeration, electrical, plumbing and hydronics contractors. There's no door-contractor license. | ORC 4740.01 |
| Electrical contractor | Acting as an electrical contractor requires a state license. | ORC 4740.13; license lookup |
| Dayton registration | Electrical contractors register with the City: a copy of the state license, a $10,000 bond, and $250 for one year (2026 form). | City of Dayton |
| Centerville registration | Electrical, gas-piping, HVAC and plumbing contractors register with the City every year. | City of Centerville |
| Minor repairs | The code lets minor repairs go ahead without a permit application. That exemption leaves out replacing electric wiring and removing or changing a required way out of the building (2024 OBC §102.10.2). | OAC 4101:1-1-01 |
| Permit office | It depends on the address: a city department or Montgomery, Greene or Miami County. | Dayton-area permit offices |
| Photo eyes | Test monthly; beam no higher than six inches (DASMA, citing UL 325 and manufacturer instructions). | DASMA TDS 382 |
The provider and the issuing office confirm what applies to your door.

Commercial garage door questions
Can a broken commercial door spring be fixed the same day?
We can't promise timing. The company that takes the request confirms availability. Say whether the door is stuck open or stuck closed.
Is it safe to open the door by hand after a spring breaks?
No. A door with a broken spring or cable can be very heavy or can drop. Keep people clear and call.
Do we need a permit to replace the door opener?
Ohio's building code requires approval to install or replace an electrical system (§105.1), and electrical contracting needs a state license. Inside Dayton, the electrical contractor must also be registered with the City. Ask the permit office for your address. The provider and that office confirm what applies.
How often should photo eyes on a commercial door be tested?
DASMA says monthly, following UL 325 and the opener maker's instructions.
Can just the damaged panels be replaced?
Sometimes, if replacement sections are still available for that door. The provider confirms after seeing the model and the damage.
Do you handle home garage doors?
No. This line is for commercial buildings only.
