Garage Door Cable Repair in Augusta, GA
Lift cables hold the bottom corners of your door against spring tension. When one frays, slips or snaps, the door can drop or hang crooked.
Professional Repair for Broken and Loose Garage Door Cables
On a torsion-spring door, two steel lift cables run from the drums on the spring shaft down to the bottom brackets on each side of the door. On an extension-spring door, cables run through pulleys to the track hangers. Either way, those cables carry the spring force that lifts the door — and they are under tension whenever the door is closed.
That tension is what makes cable work dangerous. We replace damaged cables in pairs, re-seat drums and bottom brackets, and rebalance the door so both sides lift evenly.
- Frayed, rusted or broken lift cables
- Cables that came off the drum
- Bottom bracket corrosion and damage
- Extension spring safety cables
- Door rebalancing after cable work
Signs of a cable problem
- One side of the door sits lower than the other when closed.
- A cable is hanging slack or lying on the floor next to the track.
- You can see broken strands or rust near the bottom corner of the door.
- The door jerks, tilts or makes a snapping sound as it starts to move.
- The door stopped partway and one side looks higher.
Why cables fail
Wear at the bottom bracket. The lowest part of the cable sits near the floor where rain, pressure-washing water and road salt from vehicles collect. Rust weakens individual strands until the cable fails.
Slack from a broken spring. When a torsion spring breaks, the cables can lose tension and unwind from the drums.
Obstruction or misalignment. If the door binds in the track while closing, the cable on that side can go slack and jump off the drum.
Age. Cables are wear parts. If one has failed, the other is usually close behind, which is why we replace them as a pair.
Never loosen the set screws on a cable drum or remove a bottom bracket. With a torsion spring wound, those parts hold enough force to cause serious hand and face injuries. Leave cable work to a trained technician.

How cable repair works
- The door is secured in the closed position and the spring tension is safely unwound.
- Old cables are removed and the drums, bottom brackets and pulleys are inspected.
- New cables of the correct length and rating are installed on both sides.
- Springs are re-tensioned and the cables are checked for equal tension.
- The door is balance-tested and cycled with the opener.
Extension-spring doors
Extension springs need a safety cable threaded through each spring. If a spring breaks, the safety cable keeps it from whipping across the garage. If your extension springs don’t have safety cables, ask us to add them during the repair.

Garage Door Cable Repair FAQs
Can I replace a garage door cable myself?
We advise against it. Cable work requires unwinding and rewinding the torsion spring, which is one of the most dangerous tasks on a garage door. A slip can cause serious injury.
Why replace both cables if only one broke?
Both cables have seen the same cycles and the same moisture. If one has failed, the other is usually worn too. Replacing them together keeps tension even so the door lifts level.
Is it safe to use the door with a frayed cable?
No. A frayed cable can snap without warning, letting one side of the door drop. Stop using the door and call for repair.
What causes a cable to come off the drum?
Common causes are a broken spring, the door binding in the track while closing, or the door hitting an obstruction. The cable goes slack and can unwind or jump off.
Do extension springs need cables?
Yes. Extension-spring doors use lift cables through pulleys plus a separate safety cable through each spring. The safety cable contains the spring if it breaks.
How long do garage door cables last?
It depends on use and moisture exposure. Cables near wet floors corrode faster. Checking them during an annual tune-up catches fraying before a failure.
