Is this the right page for your door?
This page is for sectional doors: doors made of panels that roll up and back along tracks on each side. Most dock doors and garage-style bay doors work this way. A steel curtain that coils up above the opening is a roll-up door, and a fast fabric door is a high-speed door. Each has its own page.
| If the door… | It's a… | Go to |
|---|---|---|
| Is made of wide panels that bend at hinges and ride up tracks to lie under the ceiling | Sectional overhead door | This page |
| Is a curtain of narrow steel slats that coils around a drum above the opening | Rolling-steel (roll-up) door | Roll-up door repair |
| Is fabric or thin panels and opens very fast, often at a freezer or busy aisle | High-speed door | High-speed door repair |
| Has a fire label and closes on its own in an alarm | Rolling fire door | Rolling fire door repair |
| Sits over a dock with a leveler below | Sectional dock door (this page) plus the leveler if that's broken too | Both |

What's wrong with the door?
These rows help you describe what you see. They aren't a diagnosis.
| What you see or hear | What a qualified tech may check | Why it matters | How to report it |
|---|---|---|---|
| A loud bang, then the door is very heavy or won't lift | Torsion springs (the tightly wound springs on a bar above the door) and cables | Springs and cables hold stored force. A broken one can let the door drop | "We heard a bang and now door 4 won't lift." |
| Door hangs crooked or came off its tracks after a hit | Tracks, rollers, hinges and panels | A door off its tracks can fall | "A forklift hit door 2 and it's off track." |
| Door starts to close, then goes back up | Photo-eyes, the bottom safety edge, operator force and limit settings | These are the safety devices that stop a door from closing on someone | "Door 6 reverses every time we try to close it." |
| Operator hums or clicks but the door doesn't move | Operator, drive, and whether the door is disconnected or jammed | Running a motor against a stuck door can damage more parts | "The opener hums but the door doesn't move." |
| A cable looks frayed, loose or off its drum | Cables and drums | A cable holds the door's weight on one side | "There's a loose cable on the left side." |
| Cracked, bent or caved-in panel | Panel and hinge condition, and whether that panel can still be ordered | A bent panel can bind in the tracks | "The bottom panel is caved in." |
| Daylight or drafts under the door | Bottom seal and weatherstrip | Lets in weather and pests, costs heat | "Big gap under door 3." |
| Door is noisy, jerks or shakes | Rollers, hinges, track alignment, spring balance | Often a warning before a bigger failure | "Door 1 shakes and grinds when it moves." |
Need emergency commercial garage door repair on Long Island?
Call and say first that the door is stuck open or unsafe, then give the address and the door number. Keep people and forklifts away from it, and don't force it. Don't pull the emergency release on a door with a broken spring or cable. The door can drop hard. Whether and when someone can come is confirmed by the provider on the call.
A door stuck open is a security and weather problem. Say "stuck open" first so the call is handled that way. If the building can't be locked up another way, say that too.
If the door is stuck open, say so first.
Openers and operators
An operator is the motor that opens and closes the door. It works together with the wall controls, photo-eyes and safety edges. On commercial doors these parts are one system, and UL 325 is the product safety standard for door operators and their entrapment protection — the parts that keep a door from closing on a person. Read more on UL 325 for commercial doors and commercial door operator types.
Operator wiring is electrical work. On Long Island that matters:
- Suffolk County licenses master electricians for electrical work, commercial included, except in a town or village that has its own licensing law (Suffolk Code Ch. 563, Art. XI).
- In Nassau, the towns license electricians. That includes Hempstead (Ch. 84), North Hempstead (§2-63) and Oyster Bay (§107-16.1).
If the fix involves new wiring or a new operator, ask who holds the electrical license and who files the inspection. The provider and the issuing office confirm what applies.

What affects the price of commercial overhead door repair?
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.
| Price driver | Why it changes the price | Ask |
|---|---|---|
| Visit or diagnostic charge | Many companies charge to come out and look | "Is there a trip charge? Does it go toward the repair?" |
| Springs | Many panel doors use two springs, and they're often replaced as a pair | "One spring or both, and why?" |
| Door size, gauge and insulation | Heavier doors need heavier springs and parts | "Do you have parts for this size?" |
| Panels | A single panel may need to be ordered, and older models can be hard to match | "Can this panel be ordered? How long?" |
| Operator and electrical | A new operator adds parts, and may add electrical work and an inspection | "Does this need an electrician or a permit?" |
| After-hours work | Some companies price nights and weekends differently, if they offer them | "Is there a different rate after hours?" |
| Access | Lifts, working height, traffic and your site's safety rules | "Do you need a lift?" |
Ask whether you're hearing a call-out fee, a starting price, a fixed price for a set scope, an estimate or a final quote. Get the scope in writing before you sign. For wider numbers, see our research on commercial garage door cost.
Repair or replace the door?
Replacement makes sense when several panels are damaged, the tracks or frame are bent badly, parts for that model are no longer made, or the door no longer fits how you use the bay. Read commercial garage door repair vs. replace. If a new door is the answer, see commercial garage door installation on Long Island.

Long Island rules that matter for overhead doors
Most ordinary repairs don't need a building permit. Replacements, new openings and new operators are when to ask. Permits come from the town, city or village where the facility sits, not the county.
- Town of Islip: no permit is needed to replace a door that fits the existing opening with no change to the headers or studs. A permit is needed if they change (Town of Islip, June 16, 2025).
- Town of Huntington: ordinary repairs that replace existing work, and equipment swaps that keep the original specs, are excused from permits (Huntington §87-14).
- Town of Babylon: the commercial permit fee is tripled if work starts before the permit is filed (Babylon §89-19).
- Home-improvement licenses in Nassau and Suffolk are written for homes, so they aren't the credential for commercial door work (Nassau, Suffolk §563-16).
- Wind rating: for a commercial exterior replacement, ask the building office or design professional what design wind pressure applies to that opening, and check the door's tested rating (2025 NYS Existing Building Code).
The full office-by-office table is on the Long Island dock and door repair page. The provider and the issuing office confirm what applies to your job.

Questions about commercial overhead door repair
Why won't my commercial garage door close?
The most common causes a technician checks are blocked or misaligned photo-eyes, a door that's off its tracks, a broken spring or cable, and operator settings. Don't keep pressing the button or force the door. Call and describe what it does.
Can one broken spring be replaced by itself?
Sometimes, but many companies replace both springs on a two-spring door so they wear evenly. Ask the provider which it recommends and why before you approve it.
Do I need a permit to replace a commercial overhead door on Long Island?
It depends on where the building is and what changes. The Town of Islip says a door that fits the existing opening with no header or stud changes needs no permit. Other towns and villages have their own rules, so ask the building office, especially if the opening, header or wiring changes.
Do you work on home garage doors?
No. This line is for commercial doors on commercial buildings. A residential garage company is the right call for a home.
