Fixed the Same Visit
Most repairs are done in one trip. If a part needs sourcing, we tell you that upfront instead of guessing.
Booking a Visit
We run maintenance visits across the service area that stretches from San Francisco out to Daly City, Colma, Brisbane, and South San Francisco on the near side, and up through Sausalito, Belvedere, Tiburon, and the Tamalpais-Homestead Valley on the north side. A standard visit covers the spring, the track, the rollers, the opener chain or belt, and the hardware that holds the whole assembly to the framing. We check tension, lubricate moving parts, and tighten what's worked loose.
If we find a part that's cracked or bent, we tell you what it is and what it costs before we touch it - we don't swap parts you didn't agree to. One honest limit: if a spring is original to a house built in the early 1960s and the manufacturer no longer makes that gauge, we may need to order a compatible replacement rather than have it on the truck, and that can add a few days to the job. Across the 449,915 households and 167,337 owner-occupied houses in this service area, a lot of doors are original or close to it, so we plan visits with that in mind rather than assuming parts are stock.
What the Repair Takes
A maintenance visit is not a repair, but it's what keeps a repair from turning into a replacement. We inspect the torsion spring for rust and stretch, check cable wear at the drum, test the safety reversal on the opener, and look at panel seams for the kind of hairline cracking that shows up on doors from the 1962 median build year and earlier. On a two-car door with a single torsion spring - common in this housing stock - we check that the spring is still rated for the door's weight, since decades of small adjustments by previous owners sometimes leave a mismatch.
We re-torque hinges, clear track debris, and lubricate rollers with a product rated for a marine-air climate rather than a general household oil that washes out fast. If a cable is fraying or a roller has gone to bare steel, we'll say so and quote the fix separately. The visit itself usually runs under an hour once we're on site, though older doors with hand-wound springs from before automatic openers were standard can take longer to get safely apart and back together.
Why It Happens Here
Most of the doors we service sit on houses built between 1938 and 1988, with the median landing around 1962, and across the 52 named areas we cover the stock runs heavily 1960s and 70s. That means original torsion springs, older track hardware, and openers that have been swapped once or twice but bolted to framing that's never been touched. The mild temperate climate band this city sits in doesn't throw hard freezes or big temperature swings at the hardware, so springs don't fatigue the way they do in places with real winters.
What it does throw is damp, salt-heavy air, day after day, and that corrodes cable and spring coating from the inside even when the door looks fine from the driveway. A door that's never had a hard freeze crack a panel can still have a spring that's rusted through at the coil, and that's the failure we catch on a maintenance visit before it snaps under load.
What You Are Seeing
A door that groans on the way up, hesitates halfway, or closes a beat slower than it used to is usually telling you the spring has lost tension - not that the opener is failing. A grinding sound at the top of the track often means a roller has flattened on one side, which happens faster here because of the moisture in the air working on the bearing grease. If the door looks slightly crooked when it's down, one cable has probably stretched more than the other, which is common on original hardware from the 1960s and 70s that's never been rebalanced.
Rust streaks on the spring coil or on the bottom bracket are worth a call even if the door still opens fine - by the time a spring snaps, it usually takes the cable and sometimes a section of track with it. None of these need an emergency call. They need a maintenance visit before the next one does.

Frequently Asked Questions
How often should I get garage door maintenance in San Francisco
Once a year is reasonable for most houses here, given the mild climate and the age of the housing stock. If your door is original to a house built before 1970, we'd lean toward checking it more often since the hardware has had more decades to corrode or fatigue in the coastal air.
Does maintenance prevent a spring from breaking
It catches most of what leads to a break - rust on the coil, a cable pulling unevenly, a bracket working loose - before the spring actually snaps. It won't extend the life of a spring that's already at the end of its rated cycles, and on original hardware from the 1960s that's often where we are.
Do you service areas outside San Francisco itself
Yes. We cover a service area that includes Daly City, Colma, Brisbane, Sausalito, Belvedere, Tiburon, and the other towns within roughly 7 to 15 miles, and each of those has its own page with details specific to that town's housing.
Is maintenance worth it on an older door
Usually, if the panels and track are sound. A lot of houses here have doors original to construction between 1938 and 1988, and keeping the spring and hardware serviced is cheaper than a full replacement, right up until the door itself starts cracking at the seams.
