The Complications

The tricky part isn't the cable, it's the spring tension sitting behind it. A torsion spring under load will whip a bar or a cable if it's released wrong, and that's not a repair we'll walk a homeowner through over the phone - it's a job for someone who does it daily.

Spring nearing end of life

If the spring itself is also near the end of its life, which is common on a door this age, we'll say so before we quote a cable-only fix, since replacing a cable on a dying spring just means a second call in a few months.

Cable gauge and drum fit

Parts fit is the other issue. Drum size and cable gauge vary by door manufacturer and age, and an off-spec cable will unwind unevenly or chew up the drum groove.

Stock sizes and waits

We carry stock sizes for the hardware common to homes built in this window, but a nonstandard or import door sometimes means a short wait on a part - we'll tell you upfront if that's the case rather than force a wrong-size cable onto the drum.

What the Fix Involves

A cable repair isn't just splicing a frayed wire back together - the whole cable gets replaced, matched to the drum size and gauge your door actually uses.

Torsion cable winding steps

On a torsion system, that means releasing spring tension first, pulling the old cable off the drum, and winding a new one to the same number of drum turns so the door sits level on both sides.

Pulley and bracket checks

On an older extension-spring setup, the cable runs through a pulley at the bottom bracket, and that pulley and bracket usually get a look too, since a worn cable often means a worn pulley. We check both cables even when only one has failed. If one side gave out from age or wear, the other side is on the same clock and close behind.

Drum burrs and rust

We also check the drum and bottom bracket for burrs or rust that will chew through a brand-new cable in a season. A cable job is quick compared to a spring swap, but doing it right means balancing the door afterward, not just hanging a new wire and calling it done.

What You Are Seeing

The usual sign is a door that drops crooked - one corner sags lower than the other, or the door stops halfway and tilts. Sometimes you hear it before you see it: a sharp snap or pop from the garage, followed by the door refusing to move, or moving but grinding against the track on one side. If a cable has come off the drum but hasn't broken, the door might still open partway before binding or jumping the track.

A fully snapped cable on one side usually means the door is stuck, often partway open, with real weight hanging unevenly on the remaining hardware. Don't force the opener past this point - a door caught halfway on a bad cable can drop the rest of the way without warning, and it's heavy enough to take a bumper or a foot with it. If you're not sure which side failed, a flashlight under the door will usually show a loose, kinked wire hanging off one drum.

Why This Fails Locally

Most of the garage doors we're called out to run on hardware from the same build window: housing in this area went up mostly between 1991 and 2013, with the median landing around 2002, and four separate pockets of that 2000s-era construction make up the bulk of what's still standing. That means a lot of cables out there are the original factory wire - the same gauge, same coating, installed the same year the house was framed, and now twenty-plus years old.

Spring Hill sits in a cold-moderate climate band, and that's the part people miss. It's not brutal cold, but the yearly swing between summer heat and winter cold is exactly what work-hardens galvanized cable - it flexes, contracts, flexes again, and the zinc coating that protects the wire wears thin at the drum contact point faster than in a milder climate. Add twenty years of that cycle to a cable installed in 2002 and a snap isn't bad luck, it's the finish line. Newer doors in the area, built after a full spring and cable swap, don't show this pattern nearly as often.

Questions

Common questions

Can I drive on one broken garage door cable until the other side goes too?

No. With one cable snapped, the door is unevenly supported, and the remaining cable and drum are carrying weight they weren't built to hold alone. Even if the door looks stuck in place, it can shift or drop further without warning. Treat it as off-limits until both sides are checked and the broken one is replaced.

Is a cable repair cheaper than replacing the whole door?

Almost always, yes - a cable is a small part of the system. The exception is a door old enough that the springs, rollers, and track are all near failure together, where a cable fix just delays the next call. We'll tell you plainly if your door's past the point where patching it still makes sense.

Why did my cable snap when the door hasn't been used any more than usual?

Cable failure is mostly about age and coating wear, not use. A lot of homes in this area have doors built in the 1990s and 2000s with the original factory cable still installed. Twenty-plus years of seasonal temperature swings wears the zinc coating thin at the drum, and the cable eventually gives out regardless of how often the door's been opened.
