Upland Garage Door Co. provides garage door cable repair in Upland for doors hanging crooked, jammed halfway, or sitting with a cable coiled on the floor. Cables are the link between the spring and the door; when one fails, the door loses half its lift on that side.
Cable failures are handled the same way on our Rancho Cucamonga service page.
What garage door cables do
Each cable runs from a bottom bracket on the door up to a drum on the torsion shaft. As the spring unwinds it turns the drum, the drum reels in the cable, and the cable lifts the door. Two cables share the load, which is why one failing makes the door tilt.
How cables fail
Fraying near the bottom bracket
The bottom few inches live closest to sprinkler spray and the wet concrete at the door’s edge. Rust starts there, strands break one at a time, and the cable eventually parts under load.
A cable that jumped off the drum
If the door hits an obstruction or the springs lose tension, the cable goes slack and winds off the drum unevenly. The door jams at an angle on the next cycle.
One cable snapped, door hanging crooked
A snapped cable drops one side of the door and leaves the full spring force on the other. The door is unsafe to operate until both cables are replaced.
Why cables and springs get replaced together
Cables and springs age on the same cycle count, and a cable job already requires unwinding the springs. If the springs are near the end of their life, replacing them in the same visit saves a second service call and a second unwind.
Cable replacement, step by step
Unwind spring tension
The springs are unwound with winding bars so the shaft can turn freely. This is the step that makes cable work a job for a technician rather than a homeowner.
Fit new aircraft-grade cables on both sides
We install galvanized aircraft-grade cable sized to the door’s weight and drum, on both sides, so the door lifts evenly.
Re-tension and level the door
Springs are rewound, the door is leveled across the opening and the opener force is reset.
Cable repair cost in Upland
Cable replacement costs less than a spring job and is quoted on site before any work begins. If springs are replaced at the same time, the combined price falls inside the $250-550 spring range.
Frequently asked questions
Can I just put the cable back on the drum?
No. The cable came off because tension was lost; without resetting the springs it will come off again on the first cycle.
Is a crooked door dangerous?
Yes. The loaded side can bend the track or pull the bottom bracket off, and the door can fall.
Do you replace both cables or just the broken one?
Both. The other cable has the same wear and the same age.
