Quick Answer

Garage door cable repair replaces the steel lift cables that work with the springs to raise and lower the door. When a cable frays, snaps, or slips off its drum, the door hangs crooked, binds, or drops on one side — and it's unsafe to keep operating. Because cables and springs share the load, we inspect both. We replace cables across the Bay Area, usually same day, in matched pairs, with free estimates and upfront pricing.

Symptoms

Is This Your Door? Signs of a Cable Problem

A failing or broken cable almost always shows itself in how the door sits and moves. If one or more of these matches your door, the cable system is the likely cause — and the door should be left alone until it's fixed.

!
The door hangs crooked or sits higher on one side
The clearest sign of a snapped or slipped cable — with one side no longer supported, the door tilts, binds, and can drop unevenly.
!
A cable is hanging loose or wrapped wrong
A cable dangling along the track or coiled unevenly on the drum has come off or broken — and the door is no longer safely balanced.
!
Frayed, rusted, or kinked cable
Visible fraying — especially near the bottom bracket or drum — or rust and kinks mean the cable is failing and due for replacement before it snaps.
!
A loud snap, then the door jammed
A sudden snap followed by a door that won't move evenly often means a cable let go — sometimes alongside a spring that failed at the same moment.
!
The door sticks or binds in the track
A cable off its drum pulls the door out of square, so it catches and grinds in the track instead of running smoothly up and down.
!
The door dropped fast on one side
When a cable fails, that corner loses its support and can fall quickly — a safety hazard for anything, or anyone, beneath it.
How We Diagnose It

Cable, Spring, or Track?

A crooked, stuck, or lopsided door can be a cable, a spring, or a door off its track — and the three are connected. Before we replace anything, our technician confirms which part actually failed, because fixing the cable without checking the springs and drums just invites a callback.

1
Find the true failure
We check whether the cable snapped, slipped the drum, or is fraying — and rule out a broken spring or an off-track door, which can cause the very same crooked, binding symptoms.
2
Inspect both cables, drums & springs
Cables rarely fail alone. We look at both cables, the drums they wind on, the bottom brackets, and the springs that share the load, so the whole lift system is sound.
3
Re-seat, tension & balance
We fit new cables, seat them correctly on the drums with even tension, then balance-test the door by hand so it runs straight and holds its position.
Why Cables Fail

Why Garage Door Cables Break

Cables wear in predictable places and for predictable reasons. Understanding why yours failed helps you choose the right fix — and avoid the second cable failing right behind the first.

Fraying where they flex most
Cables wear hardest at the bottom bracket and around the drum, where they bend and wind on every cycle. That's where fraying starts — and why we check those points closely even on a cable that still looks intact.
A broken spring shock-loads the cable
When a spring snaps, its load slams onto the cables in an instant — often fraying or breaking one in the same moment. A snapped cable and a broken spring frequently arrive together, which is why we always check both.
Coastal salt-air corrosion
Near the coast and the bay, salt air rusts and pits cable strands, creating weak points where the cable frays early. Corrosion-resistant cable is a smart choice closer to the water.
A door running off its track
A door that binds or rides off-track drags the cables out of line and chafes them against hardware, wearing them through faster than normal use ever would.
Worn drums or a loose bottom bracket
If a drum is worn or a bottom bracket is loose, the cable doesn't wind cleanly and frays where it rubs. Replacing the cable without fixing that just wears the new one out too.
Age and everyday wear
Like springs, cables are a wear item with a finite life. After enough cycles the strands simply fatigue, and a cable that's served a decade is living on borrowed time.
Honest Comparisons

Two Decisions Worth Understanding

Before you book a cable repair, two questions usually come up: should you replace one cable or both, and should you ever try it yourself? Here's our straight answer to each.

One cable vs. a matched pair

Both cables have wound over their drums the same number of times, so they wear together. The cable we don't replace is usually the next one to fray — and a new cable opposite a worn one pulls the door out of balance.

Replacing one is cheaper today; replacing both keeps the lift even and avoids a second visit in a few months.

Our straight take from the field: on a two-cable door we replace both as a matched pair — even tension, straight tracking, and no repeat call for the cable we left behind.
DIY vs. professional

Cables are tied into the same high-tension system as the springs. Replacing one means controlling that stored energy, re-seating the cable on the drum with correct tension, and re-balancing the door — not just swapping a wire.

The cable itself is cheap; the tension and balancing are where a DIY job turns dangerous and goes wrong.

Our honest take: like springs, this is a repair where professional installation isn't an upsell — it's the safe way to handle a part under serious load.
Upfront Pricing

How We Price a Cable Repair

No surprise invoices. Every cable repair starts with a free estimate and an upfront, written quote you approve before we touch the door. Rather than post a single number that may not fit your door, here are the honest factors that shape it.

One cable or a matched pair
Replacing one cable costs less than two. On a two-cable door we'll explain why a matched pair is the better long-term value, but the choice is yours.
Whether springs or drums need work
Cables rarely fail alone. If a spring, drum, or bracket caused the failure, that repair is part of an honest fix — we'll show you what's needed and why.
Door weight and size
A heavier or oversized door puts more load on its cables, which affects the cable rating and the work involved in balancing the door.
Corrosion-resistant cable near the coast
In salt-air areas, upgrading to corrosion-resistant cable can be worth it. We'll tell you whether your location justifies it rather than defaulting to the upsell.

The bottom line: you get a free estimate, an upfront price approved before any work begins, and no surprises on the invoice.

Safety First

Why Cable Repair Isn't a DIY Job

We're not trying to talk anyone out of their own garage — we just want you to make the call with the full picture. A garage door cable is part of a system holding hundreds of pounds under spring tension, and that's exactly what makes it a job for a trained technician.

  • The cables and springs carry the door's full weight together. Releasing or handling a cable without controlling that tension can let a cable or spring snap back with serious force.
  • A cable has to be seated correctly on the drum with even tension on both sides. Get it wrong and the door binds, tracks crooked, or comes off entirely.
  • Because cables and springs fail together, a safe repair means inspecting the springs and drums too — not just replacing the wire that broke.
  • After the swap, the door must be re-balanced and tested by hand. Skipping that step is how a "fixed" door comes back crooked or off-track.

None of this means living with a broken door for long — it just means the safe path is a quick visit from someone who does this every day. We carry the cables, the tools, and the experience to do it right in a single trip.

Cable Repair FAQ

Garage Door Cable Repair Questions

Straight answers to the questions Bay Area homeowners ask us most about broken and frayed garage door cables.

How do I know my garage door cable is broken?
The clearest sign is a door that hangs crooked or sits higher on one side, because a snapped or slipped cable lets that side drop or bind. You may also see a cable dangling loose along the track, a frayed or rusted cable, or the door stuck partway and catching in the track. Often there's a loud snap first, then the door jams. If the door looks lopsided, stop using it and call — running it can pull it further off.
Can I use my garage door with a broken cable?
No — it isn't safe. The lift cables work with the springs to carry the door's weight, so with one broken the load is uneven and the door can bind, jump the track, or drop on one side. Forcing it with the opener can damage the door, the track, and the other cable. Leave the door closed if you can and call a technician rather than operating it.
Should I replace one cable or both?
We almost always replace cables in pairs. Both cables have flexed and wound over the drums the same number of times, so when one frays or snaps the other is wearing out right behind it. Replacing just one leaves a worn cable opposite a new one and an unbalanced door — and usually a second service call within months. A matched pair keeps the lift even and the door tracking straight.
Why did my garage door cable snap?
Cables most often fray and snap where they flex and wind hardest — at the bottom bracket and around the drum. The other big cause is a broken spring: when a spring lets go, its load slams onto the cables, which can fray or snap them in the same moment. Rust from coastal salt air, a door that's been running off-track, and simple age all shorten cable life too. We check the springs and drums alongside the cable, because cables rarely fail in isolation.
Is garage door cable repair a DIY job?
It isn't a safe DIY repair. The cables are tied into the same high-tension system as the springs, and working on them means controlling that stored energy and re-seating the cable on the drum with the correct tension. Done wrong, a cable or spring can release suddenly and cause serious injury. It also has to be re-balanced afterward, which is why this is a job for a technician with the right tools.
How much does garage door cable replacement cost?
Cost depends on a few honest factors: whether you replace one cable or a matched pair, the weight and size of your door, whether the springs or drums also need attention (cables rarely fail alone), and whether corrosion-resistant cable makes sense near the coast. Rather than quote a number that may not fit your door, we give a free estimate and an upfront written quote before any work starts.
Do garage door cables and springs fail together?
Frequently, yes — they're one system. The springs counterbalance the weight and the cables transfer the lift, so they wear on the same timeline and a failure in one often takes the other with it. A snapped spring can fray the cables instantly, and a frayed cable can leave the door unbalanced enough to overload a spring. We inspect both on a cable call so you don't fix one and get a callback for the other.
