A broken spring or snapped cable can drop a commercial overhead door and shut a bay down instantly. SEFMG repairs and services sectional overhead and dock doors across Georgia — springs, cables, rollers, tracks, and openers — usually on the first visit.
Emergency commercial overhead door repair across Northeast Georgia — staffed around the clock.
Spring Repairs
Emergency Dispatch
Commercial overhead doors are under enormous spring tension and cycle constantly. When a spring snaps or a cable frays, the door can drop, jam, or refuse to lift — closing the opening and stopping everything moving through it.
A loud bang and a door that won't lift — or lifts crooked and heavy — almost always means a snapped torsion spring. It's the single most common overhead door failure, and dangerous to fix without the right tools.
A cable that jumps the drum or breaks leaves the door hanging unevenly and off-track — a crush hazard that needs immediate, correct repair, not a temporary fix.
Bent tracks, seized rollers, or an opener fault can leave the door stuck, crooked, or jammed against the frame — blocking the bay until it's serviced.
From dock-position overhead doors to interior and exterior sectional doors, we repair every wear point — springs, cables, rollers, tracks, panels, and openers — and get the door balanced, safe, and cycling smoothly.
Springs
Springs carry the entire weight of the door and wear out on a cycle count — so they fail suddenly, usually mid-shift. We replace broken torsion and extension springs with correctly-rated components, re-balance the door, and test it so it lifts smoothly and holds at any height.
Because springs are under extreme tension, this is one repair you never want a general handyman attempting — our techs are equipped and trained for it.
Cables & Drums
Frayed or snapped cables, worn drums, and seized rollers throw the door off balance and off-track. We replace cables and rollers, service the drums, and realign the door so it runs true and quiet without binding.
Tracks & Panels
A trailer bump or forklift strike bends tracks and dents panels, causing the door to jam or leak air. We straighten or replace tracks and damaged sections, restoring smooth travel and a proper seal. For rolling-steel and high-speed doors, see our industrial door repair.
Openers
When the door won’t respond, the problem is often the operator — a burnt motor, failed logic board, bad limit switch, or a safety sensor forcing reversal. We diagnose and repair commercial openers and controls so the door runs reliably on every command.
Safety
A commercial overhead door must reverse the instant it meets resistance. We test and repair photo-eyes, safety edges, and auto-reverse so the door protects people and forklifts. It works with your loading dock equipment as one system, so we check the full opening.
Grinding, crooked lifting, or a door that’s getting harder to open are early spring and cable warnings. Get it inspected before it drops.
Whatever’s failing on your commercial overhead door, we carry the parts and repair it right — balanced, safe, and quiet.
Correctly-rated spring replacement and door re-balancing with full lift testing.
Cable, drum, and roller replacement so the door runs true and off nothing binds.

The overhead door failures we’re called out for most — and exactly how we resolve them safely.
Platform sinks or drifts under a loaded forklift and won’t hold height.
Replace the broken torsion/extension spring with a rated match and re-balance the door.
Cable snapped or jumped the drum; door hangs uneven and off-track.
Replace cables, service the drums, reset the door on its tracks, and test balance.
Door jams, binds, or won’t close after a forklift or trailer strike.
Rebuild or replace the cylinder, service the power unit, bleed the system, and load-test the hold.
Door won’t respond, reverses on its own, or stops mid-travel.
Rebuild or replace the cylinder, service the power unit, bleed the system, and load-test the hold.

Overhead door springs don’t fail randomly; they fail after a predictable number of cycles. A scheduled inspection tracks wear on your highest-cycle doors and replaces springs on your terms — not mid-shift with a trailer waiting.
Wherever high-cycle overhead doors move product and people, we keep them lifting smoothly and safely.
High-cycle dock overhead doors under constant use.
Interior and exterior sectional doors between work areas.
Multi-dock overhead doors on tight delivery windows.
Insulated overhead doors critical to sealing and temperature.
Clean, well-sealed doors supporting compliant operations.
Peak-volume doors that can't fail during a rush.
SEFMG isn’t a rotating cast of subcontractors. Our certified technicians service commercial overhead doors every day and learn your specific doors, spring ratings, and cycle demands over time.
That continuity is why our repairs hold and our inspections catch spring wear before it strands you — the tech balancing your door has likely serviced your exact setup before.

Overhead doors are one part of your facility. We keep your dock equipment and other doors running too.
No — you should stop using it immediately. With a broken spring, the door’s full weight is unsupported, making it dangerous to operate and hard on the opener and cables. Running it can turn a simple spring replacement into a much larger repair. We can usually replace springs same-day.
That’s almost always a spring or cable problem — a broken spring on one side, a cable that jumped the drum, or a door that’s fallen out of balance. It’s also a warning sign the door is on its way to failing, so it’s worth an inspection before it drops.
Both. Many “won’t open” calls are actually operator faults — burnt motors, bad boards, failed limit switches, or safety sensors forcing reversal. We diagnose and repair commercial openers and controls along with the door itself.
Springs are rated by cycles, not years, so it depends on how often the door runs. A high-traffic dock door can wear out springs far faster than a low-use door. A scheduled inspection tracks cycle wear so you can replace springs on a plan instead of during an emergency.
We service overhead and dock doors from all major manufacturers, plus the operators that run them. Our trucks carry rated springs, cables, and rollers so most repairs are completed in a single visit.
Yes. Our emergency line is staffed around the clock. A dropped or jammed door closes the bay, so we prioritize these calls and dispatch a technician with the parts to get it moving and secure again fast.
Tell us what your door is doing — broken spring, off-track, won’t open — and our team will get back to you with a straightforward repair plan. Commercial and industrial facilities only.
