Garage Door Cable RepairLas Vegas, NV

Updated October 28, 2026

A garage door cable that is off the drum, frayed or snapped means you should stop using the door, because the fix is a job for a trained technician. The cable is what lifts each side of the door. Lose one and the door hangs crooked, jams in the tracks or will not move at all.

This guide shows you how to tell which cable problem you have, why cables fail, what a proper repair includes and what it should cost in the Las Vegas Valley. We also tell you what to do in the first five minutes and what to say when you call.

The short version

• Stop using the door the moment you see a loose, frayed or snapped cable.
• Unplug the opener so nobody presses the button by accident.
• Do not lift, lower or force a door that hangs crooked. You bend the tracks and panels, and the door can drop.
• Do not put a cable back on the drum yourself. Cables, drums and bottom brackets sit under spring tension.
• Both cables get replaced as a pair, and the door gets balanced before it is called done.
• Other guides put a cable repair at $100 to $400. We give you a firm written price at your door before any work starts.

What you can safely check in five minutes

Your eyes are the only tool you need here. Do not touch a cable, a drum or a bracket.

• Stand back and look at the closed door from outside or inside. Is one bottom corner higher than the other?
• Look at the cable on each side. A healthy cable runs straight from the bottom corner up to the drum or pulley. A loose one sags, loops or lies against the track.
• Look for fraying near the bottom bracket. Broken strands stick out like tiny wire whiskers.
• Check that the opener has power and that the wall button light is on. A dead opener and a dead cable look alike from the driver's seat.

DASMA, the garage door industry association tells homeowners to look at the cables on both sides, and says frayed or worn cables can break and cause injury. It says cables should be replaced only by a trained technician because of the high spring tension.

Off the drum, frayed or snapped, how to tell

These three look different and need different fixes. Here they are, worst first.

Snapped. You usually hear a loud bang, like something fell in the garage. One side of the door drops, the door twists in the opening, and the cable hangs or lies on the floor. The door is often jammed. This is the most dangerous one because the other cable now carries the whole load.

Off the drum. The cable is whole but it jumped out of the groove, and it hangs in loose loops like the one below. The door sits crooked and the opener may strain or stop. A cable that sits on the floor of the track or wraps the shaft is the same problem.

Frayed. The door still works, but strands are breaking near the bottom bracket or where the cable bends over the drum. This one gives you a warning. It is the cheapest time to fix it, because nothing else has been damaged yet.

A door that hangs crooked is not always a cable. A bent track or a broken spring can do it too. We sort that out at your door,, and a bent track is its own repair.

Why cables come off or break

A cable rarely fails alone. Something upstream usually let it. These are the causes in the order a technician checks them.

A broken spring. This is the big one. When a spring breaks, the cable goes slack, the door falls, and the cable can jump off the drum or kink when it snaps tight again. If your door has a cable problem and a gap in the spring, fix both. Our broken spring replacement page covers that job.

The door hit something. A car bumper, a bike, a ladder or a box left in the path can stop one corner of the door. The cable on that side goes slack for a moment and slips off the drum.

Slack from a bad setup. A cable that was never wound tight enough, a drum that was not set right, or a door that was reassembled after a panel swap can leave a bit of play. Play lets the cable ride out of its groove.

A worn drum or bracket. A drum with a chewed groove will not hold the cable in line. A bent bottom bracket pulls the cable at the wrong angle. Replacing only the cable without fixing these means the new cable fails early.

Age, dust and moisture. Steel cable is a bundle of thin strands. Over thousands of cycles, grit works into them and wears them from the inside. Water at the bottom corners, from sprinkler overspray or a leak, can rust the lowest few inches, which is where most cables break.

Torsion or extension, what changes

Your door has one of two spring setups. The cable job is similar, but the danger shows up in different places.

Torsion systems have a spring on a shaft above the door. A cable drum sits at each end of the shaft, and each cable winds onto its drum as the door rises. When a cable comes off a drum, the spring is still holding its full wound force, so the drum and shaft can move with sudden power.

Extension systems have a long spring along each side track. The cable runs over a pulley and stretches the spring as the door goes down. If the cable snaps, the spring can fly. DASMA, the garage door industry association says an extension spring door needs a safety cable that runs through the spring and ties to the wall or ceiling at each end, so a broken spring does not whip across the garage. If you do not see one, tell us on the phone.

Today's Homeowner describes the same split in its garage door cable guide and warns that torsion springs are under extreme tension and dangerous to adjust.

The bottom bracket is where it gets dangerous

The bottom bracket is the steel plate at each lower corner of the door where the cable hooks on. It looks like a plain bracket. It is not.

The cable pulls on it with spring force whenever the door is closed. Door maker Overhead Door says in its owner's manual that the bottom corner bracket and the cable retention parts are under high spring tension. The manual says only a trained door systems technician should adjust, repair or remove them. Loosening the bracket bolts with the spring wound can throw the bracket and the cable.

The bracket in the photo bent when the cable failed. We check both brackets on every cable job, because a bent one will chew through the new cable.

The same rule shows up in DASMA's inspection checklist, which says not to try to remove, repair or adjust springs or door parts such as brackets and cables.

What a proper cable fix includes

A cable replacement is quick when it is done right, and slow and risky when it is rushed. A full job has these steps.

• Secure the door so it cannot move while the spring is let down.
• Release the spring tension safely, then remove the old cable and find out why it failed.
• Replace both cables as a matched pair in the right size for your door. Heavy and solid wood doors need thicker, higher grade cables, as the HomeAdvisor guide notes.
• Inspect both drums and both bottom brackets. Replace any that are worn, bent or cracked.
• Set the cable tension evenly on both sides, so the door rises level.
• Check the spring. If it is near the end of its life, you hear about it before we leave.
• Balance the door. A good test is to disconnect the opener and lift the door by hand to waist height. It should stay close to where you leave it. A door that slams down or floats up is out of balance.
• Run the full cycle with the opener and test the safety sensors and auto reverse.

If the story ends with a bent track or a damaged panel, the job grows. That is why fixing a frayed cable early costs less than waiting for it to snap.

What it costs, and what is in the price

Swift does not publish a price list, because cables, drums and brackets differ by door. We give you a firm written price at your door before any work begins. For a rough idea, here is what other guides report for the country as a whole.

The ranges are wide for a reason. A plain cable swap sits at the low end, and drums, brackets or a bent track on the same call push it up. Our Las Vegas garage door repair cost guide compares more parts and shows how to read a quote.

If the cable call turns up a broken spring, check our coupons page first. A spring replacement offer is listed there.

The Las Vegas angle

Our desert makes a few things worse for cables, and a few of them are worth planning around.

Heat and long use. A normal year in Las Vegas brings about 78 days at 100 degrees or higher and 9 days at 110 or higher, per the National Weather Service.

Dust. Grit sticks to a cable and works between the strands. A yearly tune up cleans and checks the cable, drum and brackets, and it is the cheapest cable insurance you can buy.

Water at the corners. Sprinkler overspray or a leaky water heater can keep the lowest corners wet, which is where cable rust starts. If you see orange at the bottom of the cable, have it looked at.

What to tell us on the phone

A few details help us arrive with the right parts and a clear price.

• Did you hear a bang, and which side of the door dropped?
• Is the door stuck open, stuck closed or hanging halfway?
• Do you have one big spring on a shaft over the door, or springs running along both side tracks?
• Did anything hit the door or sit in its path?
• Is a car stuck inside? If so, say so, and do not try to force the door.
• Can you send a photo of the cable and the bottom corner? It helps us bring the right parts.

If it happened at night, our broken cable emergency service is open 24/7. You can also book online.

Repair or replace, and what to ask any company

Repair a cable that is only frayed or slipped off a good drum. Replace the cable, and often the drum or bracket with it, when it is snapped, kinked, rusted or tied to a bent bracket. Replace the whole door only when many parts have failed together and repair would cost more than the door is worth.

Before anyone starts work, ask these questions.

• What is your Nevada contractor license number? You can check it with the Nevada State Contractors Board. Our own number is on our license page.
• Is the price in writing before work starts, and does it cover both cables, the drums, the brackets and the balance?
• How much is the down payment? The Contractors Board consumer checklist says a down payment cannot exceed $1,000 or 10% of the contract price, whichever is less, unless the contractor has posted a $100,000 consumer protection bond.
• Will you tell me why the cable failed?
