Don't run the door on a bad cable
Garage Door Cable Repair in the North Shore
Frayed, rusted and snapped lift cables replaced in pairs and tensioned evenly, usually the same day.
Your garage door has two lift cables, one on each side. They run from the bottom corners of the door up to drums on the spring shaft above the opening, and together with the springs they carry the full weight of the door every time it moves.
When one frays or snaps, the door is suddenly being held on one side only. That's when doors go crooked, jam halfway, or come off their track. A cable caught early is a straightforward repair. A cable that's let go can turn into a bigger one.
If a cable has snapped: stop using the door, don't run the opener, and keep people and cars out from underneath it. Call (847) 841-0279 — we treat it as an emergency garage door repair.
Warning signs
How to tell a cable is failing
Frayed strands
The cable starts to look like a wire brush, with individual strands sticking out. It's on its way out.
Rust at the bottom
The bottom corner of the door sits on a damp floor that gets road salt in winter. Cables rust there first.
Door sits crooked
One side lower than the other when closed, or the door tilts as it moves, often means one cable has slipped or stretched.
Slack cable
A cable hanging loose when the door is closed usually means it has come off its drum.
Loud bang, door stuck
A snapped cable, or a broken spring that took a cable with it. Stop using the door.
Door off track
A failed cable is the most common mechanical reason doors come off their track.
The repair
What we do
Secure the door. We clamp it so it can't drop while we work, and release spring tension safely before touching the cables.
Replace both cables. They've carried the same load for the same number of years, so when one goes the other isn't far behind.
Check the drums and bottom brackets. A corroded bracket or a worn drum will chew through new cables. We replace them if they're the cause.
Tension evenly and test. Cables set so the door sits square, then balance and safety-reverse tested before we leave.
If the door has already come off its track, see off-track garage door repair. Cables often fail alongside springs, so we check those too — see broken spring replacement.
Common questions
Cable repair, answered
What happens if a garage door cable snaps?
The door loses support on that side and usually drops crooked, jams, or comes off its track. Stop using it, don’t run the opener, and keep people and cars out from under it. We treat a snapped cable as an emergency.
Can I replace a garage door cable myself?
We'd strongly advise against it. The cables work with springs that are under a lot of tension, and releasing that tension safely takes the right tools and experience. It's one of the more common ways people get hurt working on garage doors.
Is it safe to use the door with a frayed cable?
Not for long. A fraying cable will snap eventually, usually while the door is moving, and the door can twist or fall. Use it as little as possible until it’s replaced, and call to get it booked in.
Why do you replace both cables?
They've done the same work for the same number of years. If one has worn through, the other is usually close behind, and replacing both keeps the door balanced.
Why did my cable break?
Usually rust at the bottom bracket from a damp floor and road salt, normal wear over many years, or a broken spring that left the cable slack so it jumped off its drum.
