If your garage door hangs unevenly, one side drops lower than the other, or you can see a cable hanging loose or off the drum, you're dealing with a snapped or frayed cable.
This is a serious safety issue that requires immediate professional attention. Garage door cables are under extreme tension and work alongside the springs to lift and lower your door safely. When they snap or fray, the door becomes unbalanced and dangerous to operate.
The good news? This is a straightforward repair when handled by an experienced local engineer in your area. We carry replacement cables on the van and can usually fix it in a single visit.

Repair or Replace?
Snapped or frayed cables always require replacement—they cannot be repaired safely. However, the door itself rarely needs replacing. We replace the cables and inspect the springs and drums at the same time, as these components wear together.
Usually a Cable Replacement if:
- The door frame and panels are in good condition
- Springs are still functional (or replaced recently)
- Tracks and rollers are aligned properly
- Only the cables have failed
Consider Full Door Replacement if:
- Multiple major components are failing
- The door is 20+ years old
- Panels are severely damaged or rotting
- You want to upgrade to a modern insulated door

Frequently Asked Questions
Can I use my garage door with a snapped cable?
No. Do not attempt to open or close a garage door with a snapped cable. The door is unbalanced and could drop suddenly, causing serious injury or property damage. Disconnect the opener and call a professional immediately.
Why do you replace both cables even if only one has snapped?
Both cables have endured the same amount of wear and stress. If one has failed, the other is likely close behind. Replacing both at once prevents a second callout in the near future and ensures the door is balanced correctly.
How long do garage door cables last?
With regular use, garage door cables typically last 7–10 years. Factors like moisture, lack of maintenance, and heavy door weight can shorten this. Annual servicing can help identify fraying cables before they snap.
Can I replace the cables myself?
We strongly advise against DIY cable replacement. Garage door cables are under extreme tension and work directly with the springs, which can cause serious injury if mishandled. This is a job for a trained professional with the proper tools.
How long does a cable replacement take?
Most cable replacements are completed within 60–90 minutes, including a full safety inspection and balance test. We carry a range of cable sizes on the van to suit most door types.
What happens if the cable came off the drum?
If the cable has come off the drum but isn't broken, we can often re-wind it and check for drum damage or misalignment. However, cables that slip off have usually started to fray and should be replaced as a precaution.
Do you offer same-day repairs for snapped cables?
Yes. Because snapped cables are a safety hazard, we prioritize these callouts and offer same-day service across our coverage areas. Check availability by entering your postcode above or calling us directly.
