What It Costs
We don't have a West Valley City-specific price list to quote here, and giving you a number without seeing the door, the spring size, and whether it's a single or double door would be a guess dressed up as a fact. What we can tell you is that a 1984-built house in this area is more likely to need a full torsion spring replacement than a quick adjustment, because the original hardware is past any reasonable service life. Spring wire gauge and drum size on a door that age also don't always match what's stocked on the truck for newer builds, which can affect the job. If you want an actual number, that's a conversation for the visit, not this page.
The DIY Question
A torsion spring is wound under enough tension to break a bone or worse if the winding bars slip, and that risk doesn't go down because the spring is old - if anything it goes up, since fatigued coil wire can shear unevenly instead of releasing cleanly. We're not going to walk you through winding one here. Where a homeowner can reasonably step in is diagnosis: if the door is hard to lift by hand with the opener disconnected, or one side of the door sits lower than the other, that's a spring problem, not an opener problem, and it tells you what kind of call to make. Past that point - touching the bars, the cable drums, the center bearing - leave it alone.
Where This Job Goes Sideways
The job gets harder when a broken spring has already been ignored for a week or two. The opener keeps trying to lift against a dead spring, and that load transfers to the drive gear, the trolley, and sometimes the top roller brackets, turning a spring job into a spring-plus-opener-parts job. On a 1984-era door, there's also a decent chance the track and rollers haven't been touched since the house was built, so once we're in there with the door off its springs, we'll tell you straight if the rollers are worn enough that replacing them now saves you a second service call later - that's a real cost add, not an upsell we invent. We travel to West Valley City from West Jordan, about 6 miles out, so there's no local branch or walk-in counter here - it's a scheduled truck visit, same as the rest of the surrounding suburbs.
