Fontana, CA · Garage Door Service
Torsion and extension spring repair for Fontana houses built 1958-2007. We match the spring to the door's actual weight and cycle count, not a guess off a chart.
For spring repair specifically, we carry torsion springs in the wire gauges that match Fontana's housing stock, extension springs for the older single-track doors still running on some of the 1960s and 70s builds, and the cables, drums, and end bearing plates that fail alongside a spring rather than after it. A torsion spring rarely breaks alone - the cable on that side has usually been carrying uneven tension for weeks, and the bearing plate is worn from the wobble. We stock common sizes on the truck. Less common wire gauges, the kind you find on older custom doors or heavier insulated replacements installed on original 1970s tracks, sometimes need a day's lead time to source. That's the one honest limit here: we don't pretend to have every spring in every gauge sitting in the van, and we'd rather tell you that up front than swap in something close enough and have it fail again in a year. What we don't do on this call is chase a noisy opener or a bent track - that's a different job, with different parts. This page is about the spring, the cable it's tied to, and the drum it winds on.
We don't post a flat number here because the job isn't flat. A single door with one torsion spring costs less than a double door running two springs matched to a heavier insulated panel. Extension springs on an older single-track setup are a different repair than torsion springs on a two-inch shaft. Wire gauge matters too - the spring has to match the door's actual weight, not just its size, or it'll wear out again in a fraction of the time. What we can tell you is what drives the number up: a stripped drum, a bent shaft from a spring that snapped and whipped, or a bearing plate that's rusted into the bracket. What drives it down: catching a spring before it breaks, when it's just sagging or losing tension, rather than after it snaps and takes a cable with it. We quote the job after we see the door, not off a phone description, because two doors that look the same from the driveway can be running completely different hardware underneath.
Fontana's housing runs from 1958 through 2007, with the typical build sitting around 1978, and most of what we see across the area's 22 named communities is 1960s and 70s stock. That matters for springs because those doors were built with hardware sized for lighter panels - single layer, no insulation - and a lot of owners have since swapped in a heavier insulated door without upgrading the spring to match. The old spring keeps working, just harder, until it doesn't. Add Fontana's moderate-heat climate band: daily heat-cool cycling fatigues spring steel faster than it would in a milder band, because the metal is expanding and contracting on top of the mechanical cycle count every time the door runs. A spring rated for a certain number of cycles in a temperate spec sheet doesn't get the full number here. That combination - 1970s-era torsion hardware under a heavier modern door, in a climate that stresses the steel - is why spring failure shows up here more than the cycle count alone would predict.
The classic sign is a door that feels twice as heavy as it should when you lift it by hand with the opener disconnected - that's the spring not doing its job of counterbalancing the panel weight. On a torsion system you'll sometimes see a visible gap in the coil, or the spring hanging loose and uneven on the shaft. On an opener-run door, the motor strains, groans, or the door starts to open and then stalls partway, because the opener is trying to lift weight the spring used to carry. A door that slams down fast instead of lowering smooth is another one - no spring tension left to slow the descent. If you hear a loud bang from the garage and then the door won't budge, that's usually the spring letting go all at once, and it can happen on either torsion or extension setups. Don't run the opener again once you've heard that bang. A snapped spring under tension can whip a cable or drum loose, and running the motor against it just turns a spring repair into a track and cable repair too.
Disconnect the opener using the manual release cord and try lifting the door by hand. If it feels heavy, uneven, or won't stay up on its own partway, the spring isn't doing its job. If the door lifts smoothly by hand but the opener still won't run it, the problem is more likely the opener or the track, not the spring.
You can, but we don't recommend it. The two springs wear on roughly the same cycle count, and a fresh spring paired with a tired one puts uneven tension on the shaft. Most jobs we run on double-spring doors, we replace both at once so the door lifts evenly on both sides.
Torsion and extension springs are rated for a set number of open-close cycles, and they don't usually give much warning before they go. Heat cycling adds extra fatigue on top of the mechanical count, which is part of why springs on older Fontana-area doors tend to fail without the slow sag you might expect.
If the spring has fully let go, don't run the opener and don't force the door by hand past a few inches. The door has no counterbalance and can drop suddenly. It's not an emergency in the sense of damage getting worse by the hour, but it is a door you shouldn't be lifting or lowering manually until the spring's replaced.
