How do you fix a garage door cable?
How to fix a garage door cable: because the cables sit under spring tension, the job means relieving that tension, replacing both cables, re-seating them on the drums and re-balancing the door. A frayed or off-drum cable is not a safe DIY repair — Royal Garage Doors does it for $180–$260 + tax ($260 with bottom brackets).
Why is my garage door crooked / hanging on one side?
Usually a snapped or off-drum lift cable on that side. One cable lets go, that corner drops, and the door binds in the track. Stop using it before it jams

Signs of a failing garage door cable
- The door hangs crooked or one corner drops.
- A frayed or kinked cable dangling near the drum.
- The door binds, jams, or grinds on one side.
- Loose cable slack when the door is closed.
- The cable has jumped off the drum entirely.
Why cables fail
- Rust & fraying from moisture and road salt.
- Misaligned drums that grind the cable.
- Worn bottom brackets where the cable anchors.
- A broken spring suddenly shock-loading the cables.
How the repair works
- Open and clamp the door so the cables aren’t loaded.
- Detach the old cable from the bottom bracket and drum.
- Seat matched new cables on the drums and brackets.
- Tension both drums evenly so the door sits level.
- Cycle and balance-test the door.
Why it’s risky to DIY
Lift cables share the spring system’s tension. With an intact spring, the cable is fully loaded; if the spring is broken, the door’s full weight is unsupported. Either way a mistake can drop the door or whip the cable. Pair this with our spring guide to understand the system.
Royal Garage Doors recommendation
Cable repair is fast and same-day for a technician. Book cable repair in Toronto, check repair costs, or see track repair if the door also jumped the rail.
Frequently Asked Questions
Why is my garage door crooked / hanging on one side?
Usually a snapped or off-drum lift cable on that side. One cable lets go, that corner drops, and the door binds in the track. Stop using it before it jams or comes off-track.
Why do garage door cables break?
Rust and fraying from moisture (especially with road salt), misaligned drums that chew the cable, worn bottom brackets, or a broken spring suddenly loading the cables.
Is it safe to replace a cable myself?
It’s risky — the cables work with the springs under high tension. If the spring is intact, the cable is loaded; mishandling can cause the door to drop or the cable to whip. We recommend a technician.
Should both cables be replaced?
Yes. Cables age together; replacing the pair keeps the door balanced and avoids a second call when the other side fails.
How much does cable repair cost?
$180–$260 + tax for cables and brackets, or about $260 if the bottom brackets are replaced too. Free service call with the repair.
