Broken Torsion Springs: Farmington's Most Common Garage Door Call

Stocked Parts

Most of the calls we run in Farmington are for torsion springs, and we stock the sizes that actually match what's on the wall here. Housing in this area went up mostly between 1938 and 1986, with the bulk landing in the 1960s and 70s, so the springs we pull off the truck most often are single-torsion units sized for the lighter, narrower doors that generation of builders installed. We carry extension springs too, for the handful of older carriage-style setups that never got upgraded to torsion hardware. Rollers and end bearings matter just as much as the spring itself - we stock nylon rollers rated for a cold-severe climate band, because the cheap stamped-steel rollers that came standard on original builds seize up and flat-spot once they've been through a few hard winters. If a cable has frayed from riding a worn drum, we carry replacement cable in the common lengths for both single and double doors. What we don't carry on the truck is anything custom-cut for a non-standard door width - those orders go out to a supplier and the job gets scheduled around that lead time.Clinic.Clinic

What Causes It Around Here

Two things stack on each other in Farmington: the age of the housing and the climate band it sits in. A door built or last re-sprung anywhere from the 1950s through the 1970s is running on steel that has had five or six decades of expansion and contraction cycles, and Farmington sits in a cold-severe climate band where that cycling is sharp - hard freezes followed by thaw, repeated through a long winter. Steel spring wire fatigues faster under that kind of swing than it would somewhere milder, and once a coil starts to lose temper, it doesn't give you much warning before it lets go. Original hardware from that era is also usually a single spring on a double door, a setup that was common when the stock here was built but that puts more strain on the one coil than a modern dual-spring system spreads across two. Add a winter's worth of grease going stiff in the cold and a roller binding in the track, and that single spring is doing more work than it was ever sized for. That combination - older single-spring torsion setups plus a harsh freeze-thaw climate - is why this is the single most common service call we get here, more than openers, more than tracks.

What It Costs

We're not going to quote you a number here, because the real cost depends on things we can't see until we're standing in front of the door: whether it's a single spring or a pair, torsion or extension, whether the cable and drums have to come out with it, and whether the door is a standard width or something non-standard that needs a special-order part. What we can tell you is what drives the price up or down. A single spring on a single-car door is the simplest job we do. A double door running on one undersized original spring usually needs both the spring and a hardware upgrade to spread the load properly, which costs more than a straight swap but holds up better through the next ten winters. If the roller track is bent or the drum is grooved from a frayed cable, that gets added to the job rather than left to fail again in six months. The honest limitation: if your door is an older non-standard width, we may need to order that spring size in, and that adds a few days versus a same-day fix on a standard door.

How It Shows Up

The classic sign is a door that won't go past a few feet before the opener strains and stalls, or a loud bang from the garage followed by the door suddenly feeling twice as heavy by hand. Sometimes it's quieter: the door starts to sit crooked in the track, one side dropping lower than the other because one cable has gone slack while the opposite side still holds tension. You might notice the opener motor working harder and hotter than usual for weeks before the spring actually snaps, because a fatigued coil loses lift gradually before it fails outright. On older torsion setups common to this area's 1960s and 70s stock, a snapped spring often takes a cable with it, so a door that looks like a simple spring job sometimes needs a cable replaced in the same visit. If the door drops fast when you release it by hand rather than lowering under control, stop using it - that's a loaded spring that's already partly gone, not a worn opener.
