Uneven lifting from a loose or worn cable — across Bethesda, Chevy Chase, North Bethesda, Rockville, Potomac, Glen Echo.
Garage door cable repair restores support when a lift cable breaks, frays, or slips out of place. A door with uneven support may hang at an angle, bind in the tracks, or drop on one side. Stop using the opener if the door is crooked or hanging.
Each lift cable links a bottom bracket to a drum mounted on a torsion shaft or to a pulley in an extension-spring setup. Spring force loads the cables, while the bottom brackets anchor them. Our crew secures the door and unloads the spring before handling the cables. We check both sides, the lift hardware, and nearby parts to find what caused the cable to fail or shift.
Across Montgomery County, we arrive with tools to restrain the door and service spring-loaded parts, along with common cable sizes. We replace worn cables as a matched set, using the correct length and diameter, then seat them on the drums or pulleys and adjust the lift. Before wrapping up, we check the door’s balance and safety reversal.
When we arrive for a cable repair, we first look for a crooked door, slack cable, or frayed strands near the drums. Winter nights here average about 32°F, and about 60 nights a year drop to freezing or below. In a cold garage, we check the cables’ path and inspect the springs, drums, and rollers for stiff movement or wear before moving the door.
After replacing or resetting a damaged cable, we check the door’s balance and run a controlled cycle, watching both sides for even travel. We leave the cables seated on the drums and the door moving properly. If it starts to tilt or bind again, stop using it and call us to inspect the lift system.



During the call, we ask what signs you notice, such as a low side, a crooked door, or a loose cable. We also ask whether the door is stuck or still moving.
At the home, we inspect the cables, bottom brackets, drums or pulleys, and spring system. We give you the exact quote on site before starting work.
We secure the door, unload the spring, and replace worn cables with correctly sized matched cables. Then we seat them on the lift hardware and adjust the system.
We check the door’s balance and test its safety reversal with a 2-inch wooden block. We confirm the door moves and responds as intended before finishing the visit.
Starting prices. A door has two lift cables and one or two springs; the exact price depends on the door, the hardware grade and how many parts are replaced, and is confirmed on site before any work starts.
