Garage door cable repair is needed when one of the two lift cables frays, snaps or jumps off the drum at the top of the door. The door then hangs crooked, with one side up and the other down. In Bryn Mawr and Rosemont, Hemlock replaces the cables and resets them so both sides lift together.
A crooked door is under strain. Do not run the opener again and do not loosen the bottom brackets, because the cable is attached to a spring under tension. Stay clear of the door and call with a description of which side is low.
Signs You Need Garage Door Cable Repair
- A loose cable hanging next to the track
- One corner of the door higher than the other
- Rusty or frayed strands near the bottom bracket
- A cable wrapped wrong or off the drum at the top
Damp Garages and Rusty Cables
Garages that sit lower than the driveway can stay damp after heavy rain, and cables near the floor rust from the bottom up. We look at the bottom brackets and the floor seal while we replace the cables, since water is often the cause.
How We Handle It
Secure the door
The door is clamped so it cannot shift while cables are off.
Check drums and springs
A cable often fails because of a worn drum or spring.
Fit both cables
Cables are replaced as a pair so they stretch evenly.
Level and test
Both sides must lift and close evenly.
