Garage Door Cable Repair in Denver, CO
Lift cables carry the full weight of your garage door alongside the springs. When one frays or snaps, the door slumps, jumps the track, and becomes unsafe to operate. We replace cables in pairs and re-balance the door the same visit.
Typical pricing
Standard cable pair replacement: $165–$245. Combined with spring replacement: bundled discount.
Response time
Same-day. Cables are stocked on every truck.
Symptoms we see
- Door is slumped or crooked on one side
- Frayed wire strands visible on the cable
- Cable hanging loose at the bottom bracket
- Door drops fast when opener releases
- Loud snap followed by a tilted door
Common causes in Denver
Rust from snowmelt and salt
Cables that sit in winter slush corrode from the inside out. Most cable failures we see in Denver hit in late winter.
Bottom-bracket pulley wear
A worn pulley chews the cable strand-by-strand until it lets go. We replace the pulley and cable together.
Spring failure shock-load
When a torsion spring snaps, the cable takes the full impact. About 1 in 3 spring calls also need a cable.

FAQ
Is a frayed cable an emergency?
Yes — a frayed cable can let go without warning, dropping the door and damaging panels, the opener, or whatever's parked underneath. Stop using the door and call us.
Why replace both cables when only one is bad?
Both cables are the same age and have lifted the door the same number of cycles. The second is right behind the first.
Can I replace a cable without releasing spring tension?
No. Cables and springs work as a system; one can't be safely serviced without the other. This is a tech-only job.
