The DIY Question
A torsion spring holds enough stored energy to break a finger or worse, and the tools to wind it safely aren't something most garages have lying around. We get why people try anyway - a video makes it look like a ten-minute job, and a new spring itself isn't expensive. But the spring is only half the system. The drum, the cable, the bearing plate, and the winding bar all have to match the door's weight and the track geometry exactly, or the fix doesn't hold.
Here's the honest limit: if you're comfortable doing your own car brakes, you might be able to do this. If you're not, don't. We'd rather talk you through what to check before you call - whether the spring is actually broken versus a cable off a drum, which looks similar but is a different repair - than have you guess wrong under a loaded door. If it's a single extension spring on an older lightweight door, some owners manage it. Torsion springs on a two-car door are a different animal, and that's most of what we get called out for.
Why This Fails Locally
Housing in this service area was mostly built between 1943 and 2012
With the median sitting around 1961, and the bulk of the stock across the 62 communities we cover is 1960s and 70s construction. That matters for springs specifically: a torsion spring is rated for a cycle count, somewhere between 10,000 and 15,000 open-close cycles depending on the coil, and a door installed when a house was built in that window has had decades to burn through that rating. A lot of these are still running the factory-original spring.

The climate here is mild temperate
No hard freeze-thaw swings, no snow load stressing the coil. That's actually part of the problem rather than a saving grace: springs in this area don't snap from cold the way they do in harsher climates, they fatigue slowly from cycle count and surface rust that nobody notices until the coil lets go. With 244,769 owner-occupied houses and 749,083 households in the broader market, there's a large population of garages built in that same mid-century window hitting that same fatigue point around now, not all at once but steadily.

How We Fix It
We start by checking which spring type the door actually has - torsion mounted above the door on a shaft, or extension springs running along the horizontal tracks - because the repair and the parts are different for each. We match spring wire size and wind to the door's weight rather than installing a generic replacement, which is the shortcut that leads to a second failure in a year or two.
If one spring on a two-spring torsion setup has broken, we replace both. The second one is close behind it on cycle count, and leaving it means a second truck roll and a second door that won't open, usually at a worse time. We also check cables, drums, and the center bearing while the system is unwound, since those wear on the same timeline as the spring and are a lot cheaper to swap now than after a cable snaps under load.
Given the median household income of $93,882 across the service area, most owners here choose the full spring-and-hardware swap over a patch job, since the cost difference is small against the risk of a second failure.
How It Shows Up
The door won't open with the opener, but it also won't lift by hand, or it lifts and then drops like dead weight - that's the clearest sign a spring has gone. A loud bang from the garage, especially one that happens with no one near the door, is almost always a torsion spring letting go on its own.
Before full failure, you'll usually get warning signs: the opener strains and makes a grinding noise it didn't used to, the door looks crooked or hangs unevenly when it's partway open, or you notice a visible gap in the spring coil itself if you look up at it. Given how much of the housing stock here dates to the 1960s and 70s, the symptom we hear most is simple - 'it worked fine yesterday, and this morning it won't budge.' That's cycle fatigue catching up all at once, not a sudden event, even though it feels sudden to the homeowner.
