How It Shows Up

The door won't lift, or it lifts about six inches and stops. Sometimes you hear a bang from the garage before any of that happens - that's the spring itself letting go, usually a torsion spring snapping on the shaft above the door.

Extension springs sag

Other houses have extension springs running along the horizontal tracks instead, and those tend to stretch and sag for weeks before they finally give out rather than breaking all at once. Most of the doors we open up in San Luis Obispo went in somewhere between 1973 and 2012, with the heaviest clustering around 1982, and that date range matters more than people expect.

Cycle-rated spring life

A torsion spring is rated for a number of open-close cycles, not a number of years, and a 40-year-old spring on a door that's been opened twice a day has usually run out its cycle life regardless of how the door looks. If your opener is straining, reversing partway up, or the door feels unusually heavy when you lift it by hand with the opener disconnected, that's a spring losing tension, not a motor problem.

Spring failure takes cables

We also see broken cables on the same visit more often than people think - a failed spring that isn't caught quickly can let the door drop hard enough to kink or snap a cable, which turns a spring job into a spring-and-cable job.

Parts We Carry

We stock torsion springs in the sizes that match the 1980s and 90s builder-grade doors common across the roughly 15 named areas that make up this stretch of the Central Coast housing stock - those are the wind diameters and wire gauges we pull off the truck the most, because that's what's on the wall of most garages out here.

Extension spring hardware

Extension springs for older setups are in that stock too, along with standard cables, end bearing plates, and center bearings. What we don't carry on the truck is anything custom - oversized commercial door springs, oddball European hardware, or springs for a door that's been modified from its original configuration.

Custom spring lead time

If a job needs one of those, we order it, and that's a real lead time, not a same-day fix. We'd rather tell you that up front than quote a visit we can't close out.

Paired spring replacement

We always replace springs in pairs on a double door. A mismatched pair puts uneven load on the shaft and the opener, and it's the kind of corner-cutting that shows up as a second service call a few months later.

What You Pay

We don't post a flat number here because spring jobs vary by door weight, spring type, and whether cables or bearings need replacing alongside the spring - and we'd rather give you a real number after seeing the door than a figure that doesn't hold up on site.

Price drivers for springs

What we can tell you is what drives the number up or down: torsion versus extension, single versus double door, whether it's a straight swap or whether hardware around the spring has worn out too.

Full repair over patching

Households in this service area median around $103,381, and across the roughly 53,311 households and 27,123 owner-occupied houses we draw from, most people choose a full correct repair over a patch - replacing both springs and worn cables in one visit rather than coming back for the cable in a month.

Single-spring swap option

That's a choice we lay out plainly, not one we push, because sometimes the cheaper single-spring swap is genuinely the right call for a door that's otherwise in good shape.

Why This Fails Locally

San Luis Obispo sits in a mild temperate band - no deep freeze, no extended heat spikes - which sounds like it should be easy on garage door hardware, and in one sense it is. Springs here aren't fighting the thermal expansion and contraction that cracks hardware in harsher climates. But mild weather also means people don't think about the garage door until it fails, because there's no seasonal prompt like a hard winter to make anyone check it.

The bigger factor is simply age distribution. With most of the local stock built between 1973 and 2012 and a median year of 1982, a large share of doors in this area are carrying original or first-replacement springs that are well past their rated cycle count. A spring doesn't announce it's near the end - it just breaks, usually on an ordinary lift, not during a storm or a cold snap. That's the pattern here: failure by use and age, not by weather event, which is a different root cause than you'd point to in a harsher climate and one worth naming correctly before anyone reaches for a quick fix.

Questions

Common questions

How do I know if it's the spring and not the opener?

Disconnect the opener using the release cord and try lifting the door by hand. If it feels heavy, drops on its own, or won't stay up around waist height, that's the spring, not the motor. An opener struggling to lift a door with a dead spring will eventually burn out trying to compensate, so don't keep running it.

Can I replace just the one spring that broke?

On a single door, yes, that's common. On a double door we replace both even if only one broke, because a mismatched pair puts uneven strain on the shaft and opener and tends to cause a second failure within months. We'll tell you which situation you're in before we start.

Why did my spring break with no warning?

Torsion and extension springs are rated for a number of open-close cycles, not a calendar lifespan. A lot of the garage doors in this area date to the 1970s through early 2000s, so many springs are original and simply past their cycle count. They don't weaken gradually and announce it - they just let go on an ordinary lift.

Do you stock springs for older doors?

We carry the torsion and extension spring sizes that match the builder-grade doors common through this area's 1980s-90s housing boom, which covers most calls. Oversized, commercial, or modified hardware sometimes needs to be special-ordered, and that adds real lead time we'll flag before scheduling.
