Stocked Parts
Houses in Rancho Palos Verdes went up mostly around 1967, later than a lot of the stock closer to Inglewood, and that shows up in the hardware. By the mid-60s, double-wide garages with two lift cables and a torsion spring setup had become the standard, replacing the single-cable, single-panel doors common in older tracts. That means the typical cable job out here is a matched pair on a two-car door, not a lone cable on a single bay.
We carry standard 1/8-inch and 3/32-inch aircraft cable in the lengths that fit a seven and eight-foot door, along with the drums and fittings that pair with them. Where we run into trouble is custom-width doors or older oversized openings that some of these larger hillside-area homes were built with - if a cable was cut to a nonstandard length originally, we may need to order it rather than cut one on the truck. That's the one honest gap: we stock the common sizes, not every custom one.
On a two-cable door, we replace both cables together even if only one has snapped. The second one is carrying the same age and the same wear, and sending a truck back out in a few months for the other side costs the homeowner more than doing both now.
How It Shows Up
The door looks lopsided when it's partway up, hanging crooked instead of level
One cable has let go and the other is holding the full weight on its own. Sometimes it's a loud bang from the garage followed by the door refusing to move at all. Other times the opener runs but the door barely creeps, which usually means a cable has frayed enough to slip on the drum instead of winding cleanly.

A failed cable under tension can also pull a bottom panel out of its track, which turns what would have been a simple cable swap into a track alignment job too. That's worth knowing before you try to force the door open or closed - pushing it past a jammed cable is how a two-part repair becomes a three-part one.
The DIY Question
A snapped lift cable is under spring tension even when the door looks still, and that's the part that makes this a bad DIY job. The cable isn't the dangerous piece by itself - the torsion spring or extension springs holding the door's weight are, and you don't always know how much tension is left in a spring that's half-failed alongside the cable.
If the door is already down and you just need to keep it closed until someone can get to it, that's reasonable to handle yourself - a padlock through the track or a clamp will hold it. Trying to rewind a drum or unload a spring to get the cable off is where people get hurt, and it's not a skill you pick up from one job. We'd rather talk you through making the door safe for a day or two than have you open it up yourself.
Where This Job Goes Sideways
The straightforward version of this job is a cable off a drum, cable and drum replaced, door balanced and tested. It goes sideways when the drum itself is scored or the torsion shaft is bent, which happens more often on doors that have been running on a frayed cable for a while before it finally lets go - the uneven load wears the drum groove unevenly.
It also goes sideways on openers that have been fighting a failing cable without anyone noticing. The motor keeps trying to lift a door that's binding, which strains the gears long before the cable actually snaps. By the time we're called out, sometimes the opener needs attention too, not just the cable. We'll tell you straight if that's what we're looking at rather than quote a cable job and then surprise you.
What It Costs
We don't publish a flat price for cable repair because the job depends on whether it's one cable or a matched pair
Whether a drum or spring is also compromised, and whether the door is a standard width or one of the larger custom openings you find on some lots in Rancho Palos Verdes. What we can tell you is that we quote the job on-site before any work starts, so there's no guessing once the truck is there.
Rancho Palos Verdes sits about 15 miles out from Inglewood, farther than most of the stops on our usual route
So it helps to have a clear picture of the problem - whether the door is stuck open, stuck closed, or just hanging crooked - before we head out, so we bring the right cable gauge and drum size the first trip.
