Garage door cable repair means replacing or re-seating the steel cables that run from the bottom corners of the door up to the spring system, and it's one of the few garage door jobs that should never be a DIY project. The cables work under the same tension as the springs they're attached to. A cable that lets go while someone is working on it can whip hard enough to cause a serious injury.

If a cable has snapped or slipped off its drum, the door is either stuck or hanging crooked, and one side may drop suddenly if anything shifts. Don't try to lift or force it.

Why this one isn't a weekend project

Lift cables sit downstream of a wound torsion spring, and that spring stores enough force to move the full weight of the door, often 130 to 400 pounds. When a cable is slack, frayed, or off its drum, the spring's tension has nowhere controlled to go. Releasing or adjusting that tension safely requires winding bars sized to the spring, correct spring-rate matching so the door balances evenly once it's back together, and a controlled release process, not a wrench and a guess. A socket set gets you nowhere near the actual problem here.

This is the same warning we give on the spring replacement cost guide: a wound torsion spring can cause serious injury or death if it releases uncontrolled, and DIY spring and cable work is a leading cause of garage door injury. A trained technician has the right tools and knows how to work around stored tension safely. That's what you're actually paying for.

Common causes

Cables usually fail for one of a few reasons. Fraying from age and repeated cycling is the most common, and it's often visible on close inspection: individual strands sticking out from the main cable line. A cable can also jump off its drum if the door has been off track or out of balance for a while, which puts uneven pull on one side. Corrosion plays a role too, and dust from monsoon storms working into the drum housing can accelerate wear on hardware that isn't cleaned or inspected regularly.

What garage door cable repair costs

Expect roughly $150 to $350 for a standard cable repair or replacement, including labor, on a typical residential door. If the cable failure damaged the spring, drum, or track in the process, or if the technician finds the door needs rebalancing afterward, the total runs higher. Get two quotes before committing, and ask whether the quote includes rebalancing the door once the cable is replaced, since a door that's out of balance will just wear the new cable unevenly too.

When to call now versus when it can wait

Call right away if the door is stuck partway open, hanging crooked, or if you can see a cable has come off its drum entirely. Don't attempt to move the door manually in that state. If you notice fraying on an otherwise functioning door during a visual check, that's worth scheduling repair for soon, before it fails completely and leaves the door stuck.

Common questions

Can I replace a garage door cable myself?

No. Cables work under the same spring tension that powers the door's lift, and that stored force can cause serious injury if released uncontrolled. This job needs winding bars and training a typical homeowner toolkit doesn't include. Call a trained technician rather than attempting it yourself.

How much does it cost to fix a garage door spring and cable?

Cable repair alone typically runs $150 to $350. If a spring failed alongside the cable, which is common since the two work together, expect the total to run higher, often $300 to $600 combined for parts and labor. Get two quotes once a technician has inspected the actual cause.

What happens if a garage door cable breaks?

The door will either get stuck partway or hang crooked, with one side able to drop suddenly if anything shifts. Don't try to lift or force it manually. A snapped cable often means the spring's tension has nowhere controlled to go, which is exactly why this repair needs a trained technician, not a DIY fix.

How do you repair a garage door spring and cable?

A technician releases the wound spring's tension in a controlled way using winding bars sized to the spring, then replaces or re-seats the cable and matches the spring rate to the door's weight so it balances evenly. This isn't a socket-wrench job — the stored tension makes it one of the few garage door repairs that should never be DIY.
