Yes, replacing both garage door cables at the same time, even when only one has snapped or frayed, is almost always the smarter and cheaper choice over the life of your door, and no, repairing a garage door cable yourself is not something we recommend. Cables work under extreme spring tension, and a mistake can cause the door to slam down or a spring to release with enough force to cause serious injury. Garage Door Professional was named to the Garage Door Handbook Top 100 Garage Door Companies of 2026 and handles cable repairs across Milwaukee, Madison, and seven surrounding Wisconsin counties, and cable failure is one of the more common garage door repair calls we get, especially heading into a Wisconsin winter.

Garage door cables wear out from repeated tension cycles, corrosion, and physical damage at the drum or bottom bracket. In southeastern Wisconsin, road salt and moisture tracked into the garage over the winter speed up rust on the cable strands, and repeated freeze-thaw cycles stress the metal further. Most cables fray gradually, showing broken strands or rust near the bottom roller bracket before they fully snap, though a cable can also fail suddenly if it slips off a drum or gets pinched.
Yes, replacing both cables together is usually the better move, even if only one has failed. Cables are installed as a pair, carry roughly equal load, and are almost always the same age, so if one has worn out from tension cycles and corrosion, the other is typically close behind. Our technicians replace garage door cables as a routine part of daily service calls across southeastern Wisconsin, from Brookfield to Waukesha to Madison, and the pattern holds consistently: a homeowner who replaces only the failed cable often calls again within a year or two when the second one goes. Paying for one service call and one set of cables now costs less than paying for two separate repair visits down the road, and it keeps both sides of the door balanced instead of running one new cable against one that is already stretched or rusted.

No, DIY cable repair is one of the few garage door jobs we actively advise against, because the cables are directly connected to a torsion or extension spring system holding hundreds of pounds of stored tension. If that tension releases unexpectedly while you're working near the drum, bracket, or spring, the door can drop suddenly or the cable and spring hardware can whip loose with enough force to cause broken bones, deep lacerations, or worse. This is different from simpler maintenance tasks like lubricating hinges or tightening loose bolts, which most homeowners can safely handle themselves. Cable work requires locking the door down, releasing spring tension safely with the correct tools, and knowing how to wind the replacement cable evenly on the drum, all of which takes training most homeowners don't have and shouldn't need to acquire for a single repair.

When you call Garage Door Professional, a real person responds in under 30 seconds, so you're never left waiting with a door stuck open or closed while you weigh your options.
Garage door cable repair typically runs in the range of most standard repair calls, with pricing depending on cable length, drum condition, and whether the spring system needs adjustment at the same time. Replacing both cables together generally costs less per cable than two separate single-cable repairs, since you're only paying for one trip and one labor visit instead of two. Same-day service is available for most cable repairs across the Milwaukee metro and Madison area, and we provide a free quote before any work begins, so you'll know the exact price before a technician touches your door.
Call as soon as you notice a frayed, rusted, or slipping cable, rather than waiting for it to snap completely. A door with a compromised cable can drop unevenly, jam on the track, or come off its rollers entirely, which turns a straightforward repair into a more expensive one involving track or panel damage. If a cable has already broken and the door won't move, don't try to force it open or closed. Leave the door where it is and call for service.
A broken or fraying garage door cable is not a job to handle with a ladder and a YouTube video. Replacing both cables together saves you a second repair bill down the road, and letting a trained technician handle the spring tension keeps you and your family safe.
