Garage Door Cable Repair
Snapped or off-drum cables are a serious safety issue. We replace and reset cables correctly, under proper tension, the same day.
What We Do
Garage door cables work in tandem with the springs to support the full weight of the door as it moves. When a cable snaps or slips off its drum, the door can fall suddenly or hang at an angle. This is a safety issue — stop using the door immediately. We replace snapped cables with the correct gauge and length, reset off-drum cables, inspect the bottom brackets for damage, and balance-test the door after repair. Cable work requires releasing spring tension, which should only be done by a trained technician.
Signs You Need This Service
- Door is crooked — one side higher than the other

FAQ
Quick answers about this service.
Can I use the door with a broken cable?
No. A broken cable puts uneven stress on all other hardware and can cause the door to fall or jam completely. Call us immediately.
Do you replace both cables at once?
We inspect both and recommend replacing the second if it shows significant wear — cables on the same system wear at similar rates.
What causes cables to snap?
Most commonly: fraying from age and use, corrosion, improper tension, or a broken spring that puts sudden load on the cable.
How Garage Door Cables Work
Garage door cables are galvanized steel wire ropes — typically 1/8" or 3/32" diameter — that thread through the bottom bracket on each side of the door and wind around a grooved drum at the top of the door track. As the springs unwind (torsion) or extend (extension), the cables transfer that energy to lift the door smoothly.
Because the cables are always under the same tension as the springs, any weakness in the cable — a frayed section, a broken strand, or a drum groove that's worn smooth — puts the remaining strands under greater stress. This is why cables rarely snap without warning; they show signs of wear well before failure if you know what to look for.
Warning signs before a cable snaps:
- Frayed or unraveling strands visible near the bottom bracket
- Rust or dark discoloration along the cable length
- The cable appears slightly loose in its drum groove
- The door is slightly lower on one side than the other
- A soft grinding or clicking sound when the door moves
Cable Replacement Procedure
Replacing a garage door cable safely requires working with the spring system — either releasing torsion spring tension or disconnecting extension springs before touching the cables. This is the step that injures DIYers: springs store tremendous energy and can snap a cable or drum violently if tension is released incorrectly.
Our technicians follow this sequence:
- Disconnect the opener and lock the door in place
- Release spring tension safely before handling cables or drums
- Remove the old cable from the bottom bracket and drum
- Inspect the drum for wear, cracks, or stripped cable grooves
- Install new cable of the correct diameter and length for the door weight and height
- Wind the cable correctly around the drum — the winding pattern matters for even lifting
- Re-tension the spring system
- Test the door through multiple cycles and check for even travel
Both cables should always be replaced together. If one is worn enough to fail, the other is at the same age and wear level.
