Garage door cables are the two thin steel wires running from the bottom corners of the door up to the drums beside the springs. They cost about eight dollars each and they carry the entire weight of the door. When one snaps, the door drops on that side, twists, and usually derails — which is why a $20 part routinely becomes a $400 repair. This guide covers 2026 cable repair pricing, how to spot a cable about to fail, and why this is the one garage door problem you genuinely should not put off until the weekend.
Replacing a pair of lift cables on a standard residential door runs $130 to $250 including parts and labor. The cables themselves are $15 to $40 for the pair; the rest is the service call and the tech's time, which is typically 45 to 90 minutes because the springs must be unwound to release drum tension and rewound afterward. Most shops will not replace a single cable — they come in matched pairs and an old cable next to a new one fails within months.
Where the number climbs is collateral damage. If the door came off track when the cable let go, add $100 to $200 for realignment. If the drums are grooved or the bottom bracket is bent, add $60 to $180 per part. If the door dropped hard enough to crease a panel, you are into panel repair territory at $250 to $600. A same-visit spring replacement, often recommended because springs and cables age together, adds $280 to $500 for a torsion pair.
Cables fail gradually and give clear warning if you look. Take a flashlight and inspect the full length of both cables from the bottom bracket to the drum. Broken strands sticking out like a wire brush — what techs call birdcaging — mean the cable is on borrowed time. Rust, kinks, flat spots, or a cable that has come partly off its drum groove are all the same message.
Behavioral signs matter too. If the door closes crooked, if one side hits the floor before the other, if there is a loud clunk or scraping at the bottom of travel, or if the door has started shuddering, the cable tension has changed. Cables typically last 8 to 12 years, and they wear fastest on doors where water pools on the garage floor and wicks into the bottom of the cable, which is why the lowest few inches almost always corrode first.
When one cable snaps, all the load transfers to the other side. The door goes diagonal in the tracks, the good cable takes double duty and often fails within days, and the opener — which has no idea anything is wrong — keeps pulling against a binding door and strips its gears. What starts as a $150 repair becomes cables plus track plus opener within one or two more cycles.
There is also a real safety issue. A door with one failed cable is being held by whatever friction the twisted rollers happen to provide. It can release at any point in its travel. Until a tech arrives, keep the door fully closed, clamp locking pliers onto the tracks above a roller on each side, unplug the opener so nobody cycles it, and park outside.
This is the one repair where we are unequivocal. To free a cable from its drum you must relieve the torsion spring tension, and to reset it afterward you must wind the spring back to the correct number of turns using proper winding bars. A spring carries 200 to 400 pounds of stored energy. Slipping a screwdriver into a winding cone instead of a hardened bar is the single most common way homeowners end up in an emergency room, and it happens every year.
Extension-spring doors are marginally less dangerous but still require the door to be fully open and blocked with locking pliers before the springs relax enough to touch anything. Even then, getting the cable routing and drum seating exactly right determines whether the door tracks straight. A professional does this in under an hour with the right tools for $130 to $250. The math does not favor doing it yourself.
Ask for an itemized invoice before work starts: cables, any drums or brackets, labor, trip charge, and tax. A legitimate shop will quote the cable pair as a single line item and tell you upfront whether the springs are due. Ask how old the springs are in cycles — if the tech says they are near end of life and the door is over eight years old, doing both in one visit genuinely saves you a second $90 trip charge later.
Push back on packages that bundle rollers, hinges, bearings, and a lubrication service into a $700 total without explaining what failed. Rollers are worth doing at $80 to $180 if they are visibly worn, but they are optional. Also confirm the warranty: a year on parts and labor is standard for cables, and shops that will not put it in writing are telling you what they think of their own work.
We strongly advise against it. Removing a cable requires unwinding the torsion spring, which stores 200 to 400 pounds of energy and requires proper winding bars to release safely. Improvised tools slipping out of a winding cone is one of the most common serious DIY injuries in home repair. Professional replacement is $130 to $250 and takes under an hour.
Treat it as a same-week repair, and a snapped cable as same-day. A frayed cable will fail without further warning, and when it does the door goes off balance, twists in the track, and often derails or creases a panel. Fixing the cable alone is $130 to $250; waiting until it snaps commonly triples that once realignment and hardware damage are added.
Both, always. Cables are installed as a matched pair and wear at the same rate, so a surviving cable that shared a decade of cycles with the failed one is close behind it. The second cable costs only $8 to $20 in parts on a visit you are already paying for, versus another full service call in a few months.
Corrosion at the bottom few inches is the leading cause — water on the garage floor wicks into the strands and rusts them from the inside. Other causes include a misaligned drum that lets the cable stack unevenly, a bent bottom bracket, debris in the track forcing slack into the cable, and simple age. Most cables last 8 to 12 years.
Yes, if you keep operating the door. The opener will keep pulling against a door that is binding diagonally in the track, which strips the plastic drive gear and can burn out the motor. Unplug the opener as soon as you notice a cable problem — a $12 cable turning into a $500 opener replacement is entirely avoidable.
Not necessarily, but if the door is over eight years old and on original hardware, doing both in one visit is usually the better value. The tech has to unwind the springs to replace the cables anyway, so the incremental labor is small — often $150 to $250 less than paying for two separate service calls a few months apart.
