How We Fix It
Most of the doors we get called out to in San Martin are wider than what you'd find on a standard in-town lot, this is acreage country, and a lot of houses built here in the 1970s went up with two-car or oversized single garages meant to hold a truck or equipment, not just a sedan. Wider doors mean heavier doors, and heavier doors put more load on the lift cables at each bottom corner.
We pull the broken or frayed cable off the drum, check the drum itself for grooving or a cracked flange, and look at the matching cable on the other side, if one has gone, the other is usually close behind from the same years of wear. On a door this size we're also checking the torsion spring's wind, because a cable that failed under an already-weak spring will just fail again in a few months if we don't fix both.
We carry cable stock sized for residential doors up to and including the wider single-bay units common out here. What we don't stock on the truck is oddball drum sizes from long-discontinued opener/track combos, if your setup is one of those, we'll tell you straight and order the part rather than force a mismatch.
How to Book
San Martin is about 4 miles from our Morgan Hill base, so a cable job here doesn't mean a special trip, it's a short run down the road for us, same as any Morgan Hill call. We don't have a separate office or drop point in San Martin itself; every job here is dispatched from Morgan Hill. Call and describe what the door is doing, cable visibly snapped, door hanging crooked, cable frayed but not yet broken, and we'll get a truck scheduled. If you can safely check whether the door is a single wide bay or a standard two-car double, that helps us bring the right cable length the first time.
What You Pay
We don't publish a flat number for cable repair because the size of the door changes the job, a wide single-bay door common on San Martin's larger lots takes a longer cable and more time on the drum than a standard-width door. What we can tell you is the visit covers diagnosing both cables, not just the one that's already broken, since replacing one and leaving a worn match on the other side just means a second call later. We'll give you the number for your specific door before any work starts, not after.
How Long It Takes
A straightforward cable swap on one side of a door is usually a same-visit fix once we're on site, an hour or so, sometimes less. Where it runs longer is on the older, wider doors typical of San Martin's 1970s-era garages: if the drum is grooved from years of a worn cable riding wrong, or if the spring needs rebalancing to match the door's actual weight, that adds time. We won't rush a spring adjustment on a heavier door just to hit a shorter clock, that's how a cable fails again in six months.
The Symptom
The door drops unevenly, one corner lower than the other, or it stops halfway with a loud bang and won't go up or down at all. Sometimes it's less dramatic: the door runs but you can see one cable has gone slack or is fraying into thin wire strands near the bottom bracket. On the wider doors common here, a slack cable often shows up first as the door racking sideways in the track rather than dropping straight, the extra width means more twist when one side loses tension. If the door won't move and a cable is visibly broken, leave it down and don't force the opener.
What Causes It Around Here
Housing in this part of the service area mostly went up between 1957 and 1980, with San Martin's stock centered around 1974, old enough that a good share of doors are on their second or third opener but still running original or first-replacement cables from decades back. Cable doesn't fail on a schedule; it fails on cycle count and rust, and a door that's been opened and closed daily for close to fifty years on the same hardware is due. On the wider, heavier single-bay doors we see on San Martin's larger properties, that cable is carrying more load per cycle than a narrower suburban door would, which shortens the interval between a first fray and a full snap. It isn't a weather problem here, the climate band is mild enough that heat and cold cycling aren't the main driver the way rust and raw mileage are.

Questions, answered
Why does a wider garage door wear out cables faster?
A wider door, common on San Martin's larger lots, is simply heavier, and that weight is carried by the same two lift cables as a narrower door. More weight per cycle means more stress on the cable strands, so on oversized single-bay or two-car doors here, cables tend to fray and snap sooner than on a standard-width suburban door of the same age.
Do you have a branch in San Martin?
No. We're based in Morgan Hill, about 4 miles away, and dispatch every San Martin job from there. It's a short drive, not a separate service territory, so booking works the same as any Morgan Hill call.
Is a frayed cable an emergency?
Not always, but treat it seriously. A cable that's fraying but not yet broken can usually wait a day or two for a scheduled visit. Once it's visibly snapped or the door is hanging crooked, stop using the opener and leave the door where it is until we get there.
Will you also check the spring when you fix a cable?
Yes. On the older, wider doors typical of this area, a failed cable and a worn spring often go together, since both are carrying the same accumulated weight and cycles. We check the spring's wind and condition on every cable call so you're not paying for a second visit a few months later.
