Fixed the Same Visit
Most repairs are done in one trip. If a part needs sourcing, we tell you that upfront instead of guessing.
What Can Go Wrong
San Bruno's houses mostly went up around 1961, right in the middle of the 1938-1988 build window that shaped garage doors across this whole service area. That matters more than people think. A door built for a house from 1961 usually came with a torsion spring mounted on a metal header above the opening, or on older jobs, a pair of extension springs running along the horizontal tracks.
Both wear out the same way - metal fatigue from thousands of open-close cycles - but they fail differently. A torsion spring usually snaps clean, with a bang you'll hear from inside the house. An extension spring can stretch, then let go, and if the safety cables aren't in place, the broken piece has somewhere to go it shouldn't.
Houses in this part of the area that never had cables retrofitted are still out there. San Francisco's own housing stock runs older on average in spots, so a truck coming from the city sees a wider mix of hardware in a single day than you'd guess - which is exactly why we don't treat a San Bruno call the same as a call from a newer block.
How Long You Are Without the Door
We come from San Francisco, about 10 miles north, so there's drive time built into any San Bruno job - we won't pretend otherwise. Once the truck is there, a spring swap on a standard torsion setup is usually a same-visit fix: the door doesn't sit disassembled overnight in most cases. Where it runs longer is parts.
If the spring size on an original 1960s installation isn't something we carry stock of, that becomes a return trip. We'd rather tell you that up front than promise a single visit and miss it.
The Cost of This Job
We don't have a posted price for San Bruno spring work, and we're not going to make one up. What we can tell you is what drives the number: whether it's one spring or a pair, torsion or extension, and whether the drums, cables, or bearings on either side of an original 1960s installation need to come out with it. Median household income here runs a bit under the $152,131 seen across the wider area, and that's worth mentioning only because it's a reason to ask for a straight number over the phone before the truck rolls, not after.
What the Repair Takes
On a torsion setup, the job means clamping the door down, unwinding the old spring under controlled tension, pulling it off the shaft, and winding in the replacement to the correct number of turns for the door's weight. Get the turns wrong and the door either won't stay put or slams down too hard - this is not a job for winging it with the wrong bar.
On an extension setup it's a different process: pull the old springs off their pulleys, check the tracks for wear from years of that stretch-and-snap cycle, and add safety cables if they're missing. San Bruno's mild coastal-influenced climate means we're not fighting the kind of temperature swings that make metal brittle the way inland heat does - springs here fail from cycle count and age more than from weather, which is one less variable to chase.
What You Are Seeing
A door that won't budge, or one that budges and then drops, is spring trouble nine times out of ten. Look for a visible gap in the coil above the door - that's a snapped torsion spring, plain and simple. If instead you see one long spring stretched along a track that's gone slack or come apart at one end, that's the extension-style setup.
Either way, don't keep hitting the opener button. The opener isn't built to lift a door's full weight without spring assistance, and forcing it usually costs you the opener motor on top of the spring. If your door was installed anywhere near the 1961 median for houses in this area, assume original hardware until someone tells you otherwise.

Frequently Asked Questions
Does San Francisco Garage Door Pros have a location in San Bruno?
No, the company works out of San Francisco and travels to San Bruno for jobs, about 10 miles each way. There's no local branch here, just a truck that comes when you call.
How do I know if it's the spring and not the opener?
If the door won't move at all, or moves only partway and stops, that's almost always a spring problem, not the opener. Check above the door for a torsion spring with a visible gap in the coil, or along the tracks for a stretched or separated extension spring.
Are San Bruno's garage door springs different from newer suburbs nearby?
Often, yes. With a median build year around 1961, a lot of San Bruno houses still have original-style torsion or extension hardware rather than the newer high-cycle springs common in houses built after the 1980s.
Can a broken spring damage anything else?
It can. Running the opener against a broken spring puts the full weight of the door on the opener motor, which isn't built for that. It's also why an extension spring without safety cables is worth fixing before it fails, not after.
