Durham, NC
Broken or frayed garage door cables are common in Durham's 1970s-90s housing stock. We explain what causes it, what to expect, and how we fix it.
Pricing
We're not going to put a number here that doesn't hold up once a tech is standing in your driveway. Cable repair pricing depends on whether one cable snapped or both, whether the drum or spring went with it, and whether the door is a standard 7-foot single or a heavier double.
What we can tell you is that a single frayed cable caught before it snaps is a smaller job than a cable that's already come off the drum and let the door drop crooked in the track - that's the honest limitation here, and anyone who quotes you a flat number sight unseen is guessing same as we would be.
Call and describe what you're seeing - a door that's hanging at an angle, a loud bang followed by the door not moving, a cable visibly unspooled at the bottom bracket - and we can narrow it down before a truck ever leaves.
Across the service area, where household incomes run a median of $77,799 and most garage doors are original to houses built decades ago, we see a lot of owners trying to decide whether a cable repair is worth it versus a full opener or door replacement. Often it is. Sometimes the drum or spring underneath has worn out too, and bundling the fix saves a second call.
Warning signs
A garage door cable repair call usually starts one of two ways. Either the door won't move and one side is sagging lower than the other, or you heard a snap and now the door is stuck half-open or jammed in the track with slack cable hanging loose near the bottom roller.
Sometimes it's slower: the cable has been fraying against the drum for months, shedding thin wire strands near the bottom bracket, and the door starts to shudder or pull to one side right before it lets go completely.
If only one cable breaks on a double door, the door will usually hang at a visible diagonal instead of coming off the track entirely, because the spring system is still holding tension on the other side. That's actually the safer failure mode.
A full cable-and-spring failure at the same time is what lets a door drop fast, and that's when panels bend and tracks bow. Either way, once a cable is broken or badly frayed, the door shouldn't be opened or closed by hand or by the opener until it's looked at - stored spring tension plus a compromised cable is how people get hurt.
Our process
We start by releasing the spring tension safely, because a cable can't be replaced correctly while the system is still loaded. From there we pull the old cable, check the drum for grooves or burrs that may have caused the fray in the first place, and inspect the bottom bracket and rollers since a cable rarely fails on its own without something nearby contributing.
We replace with cable rated for your door's weight and track configuration, not a generic size, then re-tension the spring and run the door through a full cycle to check travel, balance, and that the opener's force settings haven't been thrown off by the hang-up.
If the drum is scored or the spring is near the end of its cycle life, we'll say so before we close it back up rather than leave you with a repair that fails again in six months.
On older torsion setups common in this area's 1980s and 90s-built housing, we also check that the bearing plates haven't worn enough to be the next thing to go.
Local causes
Most of the housing across this service area was built between 1967 and 2006, with a median year around 1991, and a lot of that stock clusters in the 1980s and 90s across the seven main areas we work in. Garage door hardware from that era - torsion springs, drums, and the cables wound around them - has a service life measured in cycles, and after three decades of daily use, cables that were installed with the house are well past due for failure, fraying quietly until one cold morning they don't hold. Durham sits in a moderate cold climate band, and that matters more than people expect: cable and spring steel contracts in winter, and a cable that's already frayed is far more likely to snap on a 28-degree morning than a mild one, because the metal has less give left in it. With 9,094 owner-occupied houses out of roughly 30,655 households in the area, a large share of them sitting on original or first-replacement hardware from that same build window, cable wear isn't an edge case here - it's the predictable result of age meeting weather on equipment nobody thinks about until it breaks.
Questions
No. Once a cable breaks, the door is either stuck or unevenly supported by spring tension, and forcing it with the opener can bend the track or drop the door suddenly. Leave it closed or propped as-is and call for a repair before using the opener again.
It happens, especially on a double door where both cables are the same age and see the same wear, but more often one goes first and the other follows weeks or months later if it's not replaced at the same time. We generally recommend replacing both cables together rather than one.
A broken spring usually makes a loud bang and the door becomes very heavy to lift by hand. A broken cable often leaves the door hanging crooked or stuck in the track with visible slack wire near the bottom bracket. Both need the spring tension released safely before any repair.
