We see cable failures most often right after a spring breaks, and on coastal homes where rust has been working at the bottom bracket for years. We replace garage door cables across Redondo Beach, ZIP codes 90277 and 90278.
What does a garage door cable actually do?
How do the cables fit into the door?
One cable runs on each side of the door. The bottom end hooks to a bracket at the lower corner; the top end winds onto a drum on the torsion shaft above the door. When the spring turns the shaft, the drums reel the cables in and lift the door evenly.
What if my door has extension springs?
On extension-spring doors the cable runs through a pulley at the track and acts as a safety line along the spring. If the spring breaks, the cable keeps it from flying.
Why does it matter if one side is loose?
A door lifting on one cable tilts, binds in the tracks and can fall on the loose side. That is why a snapped cable is a safety issue, not just an inconvenience.
Signs your garage door cable is failing
Most cable failures give some warning. Walk into the garage and check for:
- Frayed strands or a hairy-looking cable near the bottom bracket or the drum
- Rust or orange staining on the cable, especially at the lower end
- A cable hanging loose or sagging when the door is closed
- A cable off the drum, with slack and a loose loop
- A door that lifts crooked, one side higher than the other
- A scraping or squealing sound when the door moves
- A door that will not move after a loud snap
What does a snapped cable sound like?
Usually a sharp crack or pop, then a door that stops or tilts. If the spring let go first, you may have heard a bang instead, and then the cable slipped.
Can I see it from the floor?
Yes. Look at both lower corners of the door and up at the drums. If one side has slack or a cable looks thin and frayed, do not operate the door.
What causes garage door cables to fail near the coast?
Does Redondo Beach salt air eat through cables?
Salt makes steel corrode, and cables are braided steel strands. The lower end sits near the floor, where moisture and salt gather, and it carries the heaviest load. That is why we find rust at the bottom bracket first. Homes near the Esplanade, PCH and King Harbor tend to show it earliest.
What else makes a cable fail?
- Age and normal wear
- A broken spring shock-loading the cable
- A cable slipping off the drum from loose winding or a bent drum
- A door forced up or down while off balance
- A car or object hitting the door or the bottom bracket
- A wrong-size or poor-quality cable from a past repair
Do springs and cables fail together?
Often, yes. They share the load, so when one weakens the other is under extra strain. That is why we inspect both on every call. See our spring repair page.
How much does garage door cable replacement cost in Redondo Beach?
A typical replacement is $120–$200, covering the pair and labor. Price moves with door height, drum condition and whether other parts need work.

Should I replace one cable or both?
Both. They have the same age, the same load and the same salt exposure. If one has failed, the other is on its way, and replacing both keeps the lift even.

Cable off the drum vs. snapped cable: what is the difference?
What does “off the drum” mean?
The cable has jumped out of the grooved drum on the torsion shaft, usually from slack. It can often be re-seated and re-tensioned, but we check for damage first.
What about a snapped cable?
The cable has broken and must be replaced, along with the other side. We also inspect the spring, drum and bracket, because the cause often sits nearby.
And an off-track door?
If a loose cable has let the door slip out of the track, that is an off-track repair. Do not force it. See off-track repair.
Is it safe to fix a garage door cable yourself?
Do not. Cables are under tension from the spring system, and releasing them in the wrong order, or working with the spring still wound, can injure you.
Safe things you can do: look, take photos and call. If the door is stuck open, keep the garage secure. If it is closed, leave it closed.

Garage door cable repair FAQs
Quick answers to what Redondo Beach homeowners ask us most.
How much does garage door cable replacement cost?
Typically $120–$200 including labor for the pair.
How long does cable replacement take?
About an hour for a standard job, longer if the spring or bracket needs work.
Can I use my garage door with a frayed cable?
No. A frayed cable can snap without warning and the door can drop or twist. Stop using it and call.
Why did my garage door cable snap?
Common causes are rust, age, a broken spring, or a door that was forced while off balance.
Can a garage door cable be repaired?
A frayed or snapped cable is replaced, not patched. A cable that has only slipped off the drum can sometimes be re-seated.
Do I need to replace the springs too?
Not always. We inspect and tell you. If a spring is weak, rusty or unevenly worn, we say so and quote it separately.
Is a cable problem an emergency?
If the door is stuck, crooked or off-track, treat it as urgent. See our emergency repair page.
Does salt air really affect cables?
Yes. Rust shows first at the bottom bracket. Rinse, wipe and lubricate, and have us inspect twice a year if you are near the water.
