Professional Cable Replacement — Always Both Sides
Garage door lifting cables run from the bottom corner of the door up to the drum at the top, working with the spring system to counterbalance the door’s weight. When a cable breaks or frays, the door can drop suddenly — a serious safety hazard. We always replace both cables when one is damaged, as they wear at the same rate.
- Both cables replaced simultaneously
- Cable drum inspection & replacement if needed
- Spring system checked concurrently
- Correct cable gauge for door weight
- Full balance test after replacement
- Galvanized steel cables for longevity
