When One Cable Goes, the Whole Door Is Out of Balance
Every sectional garage door hangs from two steel lift cables, one at each bottom corner. They wind onto a drum next to the torsion spring, or route through a pulley system on older extension spring setups, and they carry the weight of the door while the spring supplies the lifting force. When a cable frays where it wraps the drum, slips off a groove, or the bottom bracket it is bolted to rusts through, the door drops unevenly on one side, binds in the tracks, or will not move at all.
A cable rarely fails on its own. It usually shows up around the same time the torsion spring is losing tension, since the two parts share the load every time the door cycles. If the spring feels weak too, garage door spring repair resets the correct counterbalance so a new cable is not carrying more strain than it should.
Older wood and wood-composite doors on the tree-lined streets of Kirkwood and Webster Groves are heavier than a standard steel door, and that extra weight wears a fraying cable faster once it starts to go. Road salt tracked into the garage over a St. Louis winter also speeds up rust on the bottom bracket and drum, which is one of the more common reasons a cable lets go without warning. If it happens after hours and the door is stuck wide open, that is the kind of same-day emergency garage door repair call we handle across the west county service area.
What Cable Repair Covers
Frayed or Broken Cable Replacement
We replace the damaged cable and its matching partner on the other side so both sides carry even tension and wear at the same rate.
Bottom Bracket Inspection
The bracket the cable anchors to takes the most stress on the door. A bent or rusted bracket gets replaced along with the cable, not just patched.
Drum and Track Check
We check that the cable is seated correctly in the drum groove and that the track it rides in is not bent, since a bent track will fray a new cable just as fast as the old one.
Torsion and Extension Systems
Cable setup differs between torsion spring doors and older extension spring doors. We match the repair to the system already installed rather than forcing a generic fix.
Full Balance Reset
After the cable is replaced, we run the door through a full cycle and check the spring balance so it lifts evenly instead of favoring one corner.
Fast, Balanced Cable Repair
Straight Talk, Fast Fixes
"One side of the door was hanging almost a foot lower than the other and I thought I'd need a whole new door. Turned out it was just the cable. Fixed same afternoon and it runs smooth now."
"The bracket had rusted through on my side door and the cable finally gave out. They explained what happened before touching anything and had it done in under an hour."
"Appreciated that they checked the spring too instead of just swapping the cable and leaving. Door hasn't made a sound since."
Cable Repair Questions, Answered
Are garage door cables easy to replace?+
Not safely without the right tools, because the cable stays under tension from the torsion spring even when the door looks still. A cable that slips while under load can snap back hard enough to cause a real injury, so this is one repair worth leaving to a technician with a winding bar and stabilizing clamps.
What should I do if my garage door cables are broken?+
Stop using the door and do not try to force it up or down by hand. A broken cable means the door is only being held by one side or by the spring alone, and forcing it can bend the track or drop the door suddenly. Leave it in whatever position it is stuck in and call for a repair.
Can I still use my garage door if the spring is broken?+
No. A broken spring means the cables and opener are carrying weight they were never designed to hold, which is exactly how a cable snaps next. Treat a broken spring as a reason to stop using the door until both are checked.
How much does it cost to repair a garage door cable?+
Cost depends on whether the bottom bracket or drum also needs replacing and whether the door uses a torsion or extension system. We give a free, upfront quote once we see the door in person, before any work starts.
What are the most common garage door repairs?+
Broken springs, frayed or snapped cables, and doors that have come off track make up most service calls in the St. Louis area, and they are often related since a struggling spring puts extra strain on the cables and rollers around it.
How common is it for a garage door spring to break?+
Torsion springs are rated for a set number of open and close cycles, typically several thousand, so most homeowners will see a spring wear out eventually. When it does, the cables nearby are usually due for a look as well.
