Garage Door Cable Repair

The most obvious signs are a door that hangs crooked, a cable visibly hanging loose or on the floor, or a door that's stuck and won't move. You may also hear a loud snap when the cable breaks. If your door tilts to one side or the opener strains but the door barely moves, a cable failure is likely.

We strongly advise against it. Garage door cables work directly with the spring system, which stores enough energy to cause serious injury. Replacing cables requires safely releasing and resetting spring tension, which demands specialized tools and training. This is one repair that's truly not safe for homeowners to attempt.

Most cable replacements are completed in a single visit. The repair itself typically takes less time than the full inspection, but we don't rush. We inspect the entire system, replace both cables, check the drums and springs, and test everything before we leave.

We always replace both cables, even if only one has failed. Cables wear at roughly the same rate, so if one broke, the other is close behind. Replacing both now prevents a second failure and a second service call.

We provide a clear, written quote after our 26-point inspection, before any work begins. The cost depends on the cable type, door size, and whether other components like drums or springs also need replacement. You'll never pay more than the price you approved.

It can be. When a cable fails, the door's weight distribution shifts dramatically. If the opener tries to lift or lower an unbalanced door, it puts heavy stress on the motor and drive system. That's why we recommend stopping use of the door immediately when you suspect a cable problem.

There's no universal timeline because it depends on usage, climate, and the quality of the original cables. In the St. Louis metro, we commonly see cables last several years under normal residential use. Regular maintenance helps catch wear early. Our $97 tune-up service includes cable inspection as part of the full 26-point check.

Both types serve the same basic purpose, but they're configured differently. Torsion spring systems use cables that wind around drums at the top of the door. Extension spring systems use cables that run through pulleys along the sides. Both can fail from corrosion, wear, or spring-related damage. We repair and replace cables for both system types.

Yes. When a cable snaps, the door can drop suddenly or travel unevenly along the tracks. This can bend tracks, pop rollers out, and crack or warp panels. The faster you stop using a door with a suspected cable problem, the less likely you are to face additional damage.
