Cable repairs run $100 to $400 installed, according to HomeAdvisor’s repair-cost page (updated June 20, 2026). That is an aggregated national range, not a price for your specific door, your region, or your spring configuration, but it tells you where to anchor. A technician has told you a cable is frayed or broken and handed you a number; that number may cover one of three different scopes of work, and the three are not the same job. Here is what separates them, and which questions to put in writing before anyone touches the door.
Stop using the door first
Before the quote means anything, the door should not be running. Unplug the opener if you can reach the plug safely. Do not try to lift the door manually or force it in either direction. Keep people, pets, and vehicles clear of it. Clopay’s maintenance guide states that frayed cables “are in danger of breaking and could cause serious injury or property damage.” DASMA’s checklist for consumers is equally direct: do not try to remove, repair, or adjust cables, springs, brackets, or related components. Call a technician and leave it there.
What a cable does, so the quote makes sense
Cables run along the sides of the door and connect to the springs. As the door opens, spring energy transfers through the cables to pull the door upward. That is why a cable quote often has a second line about springs or drums. If you want to understand how cables and drums interact mechanically, the Garage Door Science cable and drum page covers the physics. The short version: when a cable fails, something was probably working against it, and the quote may reflect that.
Option 1: replace the one frayed cable
The technician replaces only the cable that failed and leaves everything else as-is. It is the smallest job on the table, and it sits at the low end of that $100 to $400 national range. Your written quote is the only number that applies to your situation.
Option 1 is appropriate when the technician can state in writing that the second cable, the drums, and the springs all look sound, and that the failure came from normal wear rather than something mechanical working against it. If the technician cannot account for the other cable, this option is not the one to choose.
Ask: is the quote for one cable or both, and what does the other cable look like? Get that answer on the quote, not verbally.
Option 2: replace both cables
The technician replaces the failed cable and the one on the opposite side of the door. The reasoning is straightforward: the two cables have run the same cycles for the same years under the same load. Replacing only one leaves a worn cable doing half the work on a door that just demonstrated what happens when cables fail.
No manufacturer page we found states that both cables must be replaced together as a rule (unlike springs, where Clopay’s documentation does say to replace the pair, see the spring quote breakdown for that distinction). So this is a judgment call, not an industry requirement. The way to evaluate it: ask for the price of one cable and the price of the pair as two separate lines on the same quote. See what the second cable adds, then decide.
Option 3: cables, plus drums and spring balance
A cable that frays or snaps has usually been working against something. Option 3 covers cable replacement and a check of the parts the cable interacts with: the drums at each end of the torsion shaft and the balance of the door. Amarr’s owner’s manual directs homeowners to visually scan cables, springs, tracks, rollers, and hinges for wear, and to have a trained technician replace anything that shows damage. That language describes what a thorough technician looks at, not a priced scope, but it gives you a checklist for what to ask about.
Ask the technician: what did you examine besides the cable, what did you find, and is the inspection a separate line on the quote? Those three questions tell you whether the price reflects a real assessment or just a cable swap. If the door is out of balance, the new cable will be working against the same problem the old one was.
Four lines that belong on every cable quote
Two quotes are only comparable if they contain the same information. Ask for these four items in writing on any quote you receive:
- Whether the price covers one cable or both, with the cost of each shown separately.
- What the technician found on the other cable, the drums, and the springs.
- What caused the cable to fray or break, in the technician’s own words.
- Whether the door is safe to use until the repair is scheduled. Assume it is not until you have a written answer.
A technician who resists putting those four items on paper is telling you something useful before you have spent a dollar.
When the cheapest option is the right call
Option 1 is the correct choice exactly when the technician can document, in writing, that the single cable failed from wear and that everything adjacent to it is sound. It is not the correct choice when the technician cannot explain what caused the failure, when the other cable is also showing wear, or when a spring appears on the quote. In those cases, compare the wider quotes rather than defaulting to the lowest line item.
If your door is also showing age or physical damage beyond the cable, the damaged or aging door guide covers how to think through whether a repair still makes sense given what the door is worth.
What to do right now
- Stop running the door. Unplug the opener and keep the area clear.
- Call a garage door technician and tell them a cable is frayed or broken.
- When the quote arrives, check it against the four lines above. Ask for anything missing in writing before you agree to anything.
- If you are comparing two quotes, make sure both cover the same scope. A quote for one cable is not comparable to a quote for cables plus a balance check.
Frequently Asked Questions
How much does it cost to replace a garage door cable?
HomeAdvisor’s repair-cost page (updated June 2026) puts cable repairs at $100 to $400 nationally. That range covers a wide variety of door sizes, spring configurations, and regional labor rates, so it is a starting point rather than a firm price. Your written quote from a local technician is the only number that actually applies to your door.
Do both garage door cables need to be replaced at the same time?
No manufacturer rule requires both cables to be replaced together, unlike springs, where some manufacturers do recommend replacing the pair. It is a judgment call based on the condition of the second cable. If the two cables have run the same number of cycles and one has already failed, replacing both is a reasonable precaution worth pricing out as a separate line on the quote.
Can I use my garage door if a cable is frayed or broken?
No. A frayed or broken cable puts the door at risk of an uncontrolled drop, which can cause serious injury or property damage. Clopay’s maintenance documentation describes frayed cables as a safety hazard. Stop running the opener, unplug it if you can do so safely, and keep people and vehicles clear until a technician has assessed and repaired the door.
What should a garage door cable quote include?
A complete cable quote should state whether the price covers one cable or both, what the technician found on the adjacent cable and the drums and springs, what caused the original cable to fail, and whether the door is safe to use until the repair is done. If any of those four items are missing, ask for them in writing before you agree to the work.
Why does a cable quote sometimes include springs or drums?
Cables, drums, and springs work as a system. A cable that fails under normal conditions has often been working against a drum that is out of alignment or a spring that is out of balance. A technician who inspects the full system after a cable failure is checking for the underlying cause, not padding the quote. Ask what they found and whether the additional items are priced as separate lines.
Is a garage door cable repair something I can do myself?
No. DASMA’s consumer checklist explicitly states that homeowners should not attempt to remove, repair, or adjust cables, springs, or related brackets. Cables connect directly to the spring system, which stores significant mechanical energy. Incorrect installation or handling can result in serious injury. This is a technician-only job regardless of the scope of the repair.
