Garage door cables wear out gradually and are best replaced before they snap rather than after. If you see fraying, rust, or slack in the cable, or the door hangs at an angle, it's time to have them replaced, and it's a job for a technician rather than a weekend project.
Signs You Need Replacement, Not Just a Repair
- Visible fraying, broken strands, or rust along the cable.
- The cable has stretched or come loose from the drum.
- The door hangs on one side or opens unevenly.
- One cable already snapped; the other cable and supporting hardware need inspection too.
Why It Takes a Professional
Cables run under spring tension whenever the door is closed. Replacing one means safely controlling that tension, threading the new cable through the drum correctly, and rebalancing the door once it's done. It's the same tension and the same risk as spring work, just on a different part. We inspect both cables and generally quote a matched pair because they share use and exposure; one failure does not predict when the other will fail.
What a Replacement Visit Involves
- We secure the door and safely release the spring tension.
- We remove the worn cables and check the drums, rollers, and bottom brackets for related wear.
- We install new cables sized to your door and re-tension the springs.
- We test the door's balance and movement before we finish.
FAQ
How often do garage door cables need replacing?
Replace based on condition, not a fixed number of years. Look from the floor for broken strands, corrosion or slack and arrange service when any appears.
Can I replace a garage door cable myself?
We don't recommend it. The cables are under spring tension whenever the door is closed, and mishandling that tension can cause serious injury.
Do both cables need to be replaced at once?
We inspect both and usually recommend a matched pair because they share use and exposure. The quote should explain their condition and why each replacement is needed; the remaining cable's failure date cannot be predicted.
What does cable replacement cost?
It depends on the cable length, drum condition, and whether springs need attention too. See garage door repair cost for what changes the price, or call for a firm number.
