Garage Door Cable Repair and Replacement

A cable that lets go drops one corner of the door and jams it in the track. Near the bay the failure starts inside the strand where you cannot see it, so a cable can look sound and still be close to finished.

Salt Air and the Rust You Cannot See

Lift cables are galvanized steel, seven strands wound around a core. West of I-5, in Harborside, the Bayfront and Otay, damp marine mornings put moisture into the lay of the strand and corrosion works outward from the core. The first visible sign is a broken wire standing out like a whisker.

The bottom four inches, where the cable loops through the bottom bracket, is where water collects and where most breaks start. Check that spot with a rag rather than a bare hand. If the rag snags, the cable is shedding wire and the door should not be cycled again.

Setting Cable Tension Evenly Across the Shaft

Both cables get replaced, never just the broken one. The door is clamped and supported, spring tension released, and the new cable seated in the drum groove with the door fully down so the wrap starts clean. The bottom bracket gets inspected for rust and swapped if the loop has cut into it.

Drums are then set so both cables carry equal length, with the set screws torqued onto the shaft flats. The door goes up slowly by hand for the first cycle while both cables are watched for slack. Uneven tension is what pulls a door out of the track weeks later.

Licensing & Local Standards

Cable and drum matched per ANSI/DASMA 102

Cable diameter and drum size are specified against door weight and drum travel in ANSI/DASMA 102. Fitting a cable that matches the drum groove is what stops the wrap from stacking on itself and slipping off after a few dozen cycles.

Who is allowed to do this work in California

Cable and counterbalance work belongs to a D-28 licensed contractor under Contractors State License Board rules. Ask for the license number and check it before anyone touches a door under tension at your house.

Repair versus replacement, side by side
	Repair	Replace
Typical cost	$145 to $245 (estimated)	$900 to $3,800 for a full door (estimated)
Time on site	Often 60 to 90 minutes	Half a day for a standard double door
Makes sense when	The door is under fifteen years old	Panels are rusted or bent, the door is past 20 years, or repairs keep stacking up
Not the answer when	The sections themselves are damaged	One cheap part would put the door right for years

A repair works far more often than people expect, though it does have limits. Figures are guide ranges, not quotes. See the pricing guide for the full breakdown.
