Short answer
A frayed or slipped garage door cable in Houston usually costs $100 to $375 to repair according to Inch Calculator's 2026 figures. Cables are under spring tension the whole time, so a loose or frayed one is a stop-using-the-door problem, not a someday repair.
Signs a cable is failing
Broken strands on the cable
Fraying gets worse fast once it starts.
Cable hanging loose
It has slipped off the drum or snapped.
Door lifts crooked
One cable is slack or stretched.
Rust at the bottom corners
The brackets holding the cables are weakening.
A snap followed by a slam
A cable or spring has let go.
How a cable repair runs
Secure the door
Door down and clamped, opener unplugged.
Let off the tension
Spring unwound safely before any cable comes off.
Replace cables and brackets
Both cables, plus drums or brackets if worn.
Rewind and balance
Spring reset, cables tensioned evenly.
Test
Level travel, full cycles and the auto-reverse test.
What the cables do
On a torsion door, a steel cable runs from a drum on each end of the spring shaft down to a bracket at the bottom corner of the door. As the spring unwinds, the drums turn and the cables lift the door evenly on both sides.
Cables wear where they rub, rust where they sit damp, and slip off the drums when the door hits something or a spring breaks. A cable that fails on one side lets that corner drop while the other side stays up, which is how doors end up hanging crooked.
Frayed lift cable
Fraying usually starts at the bottom bracket or where the cable leaves the drum, and once strands begin breaking, the rest follow quickly. We replace both cables together, since they have the same age and the same exposure. New cables are cut to length and set with equal tension so the door rises level. We also check the drums for grooves worn by the old cable, because a grooved drum will wear through a new cable within months. Drums are inexpensive, so we replace them whenever the grooves are deep.
Cable off the drum
A cable that has jumped its drum leaves the door hanging lower on that side, and sometimes the cable is now wound backward or kinked. We clamp the door, let the spring tension off, check the cable for kinks and frays, and re-seat it with the right number of wraps before winding the spring back up. We also check why it slipped: a door that hit an obstruction, a spring that broke, or slack from a stretched cable each need a different fix, or the cable will jump again.
Rusted bottom brackets
The bottom bracket is where the cable anchors to the door, and it sits right at floor level, where water collects. A rusted bracket can let go under load and drop the door. We replace corroded brackets with new ones when we replace cables, because the bracket holds the full lift force of the spring. Brackets on doors that sat in standing water after storms are the ones we see fail most often, so after any flood we look at them first. New brackets bolt to the bottom section with new hardware, not the rusted bolts.
Why cable work belongs to a technician
A cable is the link between the spring and the door. It is under tension until the spring is unwound.
| Task | Doing it yourself | Why we handle it |
|---|---|---|
| Look for frayed strands | Safe from a distance. | Do not touch a cable under tension. |
| Stop using the door | Safe and smart. | A frayed cable can snap on the next cycle. |
| Replace a cable | Not safe. | The spring must be unwound first. |
| Loosen the bottom bracket | Never. | It holds the spring's full force. |
| Re-seat a cable on the drum | Not safe. | The drum is on a wound shaft. |
Why cables rust out in Houston
Houston's relative humidity runs above 90 percent most mornings, so the steel at the bottom corners of a garage door stays damp longer than it dries. That is where the lift cable meets the bottom bracket, and it is where we find most of the rust and broken strands. On cable calls we check both bottom brackets as a matter of course, because the bracket can fail even when a new cable looks fine.
What cable repair costs
Inch Calculator's 2026 guide puts cable repair or replacement at $100 to $375, and This Old House notes $86 to $192 in labor for cable work. Brackets, drums or a spring found broken at the same time add to that. We price on site.
- 1
Cables only or with drums. Worn drums fray new cables, so they are best replaced together.
- 2
Bottom brackets. Rusted brackets are replaced on the same visit.
- 3
Door size. Taller and wider doors use longer, heavier cables.
- 4
Spring condition. A broken spring often caused the cable to slip.
- 5
Door damage. A door that dropped may have bent sections.
Questions about this job
Garage door cable questions
Frayed or kinked cables are replaced, not repaired. A cable that simply slipped off the drum can sometimes be re-seated if it is undamaged.
Usually the door hit something, a spring broke, or the cable had slack from stretching.
Yes. They wear at the same rate, and matching tension keeps the door level.
Yes. It can snap under load and drop one side of the door.
The brackets at the bottom corners where the cables attach. They hold the spring's full lifting force.
Usually an hour or two, longer if drums or a spring also need replacing.
