Cable Repair for Los Altos Hills Garage Doors

The Symptom

The call we get from this side of the hills is usually one side of the door hanging low, or the door going crooked in the track the moment it starts to lift. Sometimes a cable has jumped the drum and is bunched up in a loose coil. Sometimes it's already parted and the door won't move past six inches without binding.

The service area overall was mostly built between 1947 and 1985, with a lot of 1960s stock. Los Altos Hills runs later than that average, with most garages going up around 1976. That matters for cable work because mid-70s construction here often paired wider, taller single doors with extension or early torsion setups sized for bigger openings and heavier panel stock than you'd find on a standard tract garage from a decade earlier. Bigger door, bigger spool of cable, more load on each strand when one starts to fray. A worn cable on a door this size doesn't give you much warning before it lets go.

Time on the Job

A straightforward cable replacement on a double door is usually a same-visit repair once we're on site, including re-tensioning the spring system and checking both drums for wear. Doors with the wider openings common in this area take a little longer to set and balance correctly than a standard single-car width, since the extra length of cable has to track evenly on both drums or the door will pull to one side again within weeks.

We're coming out from Campbell, about 12 miles away, so the travel is part of scheduling a visit rather than something we add on site. We don't carry a branch or depot in Los Altos Hills itself - the truck comes loaded for the job based on what you describe on the phone, and that's the honest limitation: if the door turns out to need a part we didn't bring, like a replacement drum that's cracked rather than just worn, that's a second trip.

What the Fix Involves

Both cables get replaced as a pair, never just the broken one. A cable that's lasted the same years as its twin is close behind it in wear, and bringing someone back out in a month for the second failure isn't a good use of anyone's time or money.

We pull the old cables, inspect the drums and bottom brackets for the gouges a frayed cable leaves behind, and check that the track is still plumb on both sides - on the wider doors common to 1976-era construction here, a cable failure often takes a little bit of the track alignment with it before anyone notices the door is off. New cables get sized to the drum and door weight, not just cut to the old length, then the door gets cycled and the spring tension rechecked. On an extension-spring setup, we also look at the safety cables running through the springs themselves, since those are a separate line from the lift cables and get overlooked.

Doing It Yourself

A garage door spring holds enough stored energy to cause a serious injury, and the cable is directly attached to that spring under tension. We don't recommend DIY cable replacement, and that's not a sales line - it's the actual risk. Releasing tension on a torsion or extension system without the right bars and clamps is how people lose fingers or get hit by a bar that slips.

What you can safely do yourself: pull the emergency release cord so the door is disconnected from the opener, leave the door down, and don't try to force it closed or open by hand past the point of resistance. If the door is partway open and crooked, don't put a car under it. That's the extent of the safe DIY step here - the rest is a call.

The Cost of This Job

We don't post a flat number for cable repair because the cost depends on door width, whether it's a single or double, and whether the drums or track need attention along with the cables. A wider door with heavier panels, which is common in this part of the service area, uses more cable and takes more time to balance than a standard single-car door, so it runs higher than the smallest jobs we quote in Campbell itself. We give a real number over the phone once we know the door size and what's actually failed, not after we're already there.

Booking a Visit

If a cable's already broken, don't run the opener trying to force it - that's how a bent track or a cracked panel gets added to the job. Call and describe what you're seeing: which side is low, whether the cable is visibly off the drum, whether the door moves at all. We'll get a sense of what's needed before the truck leaves Campbell.
