Torsion on steel tracks
That matters for springs because doors from this era tend to run standard torsion setups on steel tracks rather than the older extension-spring, flag-bracket arrangements we still run into on pre-1960s stock elsewhere.
Northville, Novi
Spring repair for Northville's 2,574 households, built mostly around 1970. We drive the 3 miles from Novi with the right spring size already on the truck.
The repair
Northville is a small market as these things go - about 2,574 households, which means we're not guessing at what's behind the door. A town this size runs a narrow band of door sizes and spring setups, built mostly around the same years, so the spring that failed on one street usually matches the spring that'll fail three streets over.
That's useful, because it means less time standing in a driveway measuring wire gauge and more time actually swapping the part. Most of what we see here is a broken torsion spring on a double door, sometimes a single extension spring pair on an older single-car door that was converted at some point.
The job itself is the same everywhere in our service area: measure the old spring's wire diameter, length, and inside diameter, match it, wind it to the right number of turns for the door weight, and check the opposing spring while we're there since they usually fail close together in age.
What changes town to town is how often we're matching 1960s hardware versus something newer, and in Northville it skews toward the newer end of what we handle.
On the truck
Northville's housing mostly dates to around 1970, which puts it toward the newer side of the service area's overall range of 1938 to 1991 construction.
That matters for springs because doors from this era tend to run standard torsion setups on steel tracks rather than the older extension-spring, flag-bracket arrangements we still run into on pre-1960s stock elsewhere.
We carry a working stock of torsion springs sized for the common door weights from that build period, plus the extension spring pairs for the handful of older or converted doors that still turn up. We won't pretend we carry every spring ever made.
Some odd European imports or discontinued heavy commercial springs need to be special-ordered, and if that's your situation we'll tell you straight instead of jury-rigging something that won't hold. For the typical 1965-to-1980-built door, though, the part is usually on the truck the day we come out from Novi.
Watch-outs
Winters here are the same cold-climate severe conditions as the rest of the region, and that's hard on spring steel regardless of what year the door went in.
Cold makes the metal more brittle and less forgiving right at the moment a spring is already near the end of its cycle count, so failures cluster in the coldest stretches.
A spring rated for 10,000 cycles doesn't care what town it's in, but a household that opens the door four times a day wears through those cycles faster than one that opens it twice.
The other thing we watch for on 1970-era doors specifically is a mismatched spring from a prior repair - someone replaced one side years back with whatever was on hand, and now the two springs are pulling unevenly, which wears the opener and the cables faster than a clean break would. We check both springs even when only one has snapped, because leaving a mismatched or near-end-of-life spring on the other side just means a second call a few months out.
Booking
We work out of Novi, about 3 miles away, so a Northville call isn't a special trip - it's a normal part of the day. We don't advertise a guaranteed arrival window here because that's a promise we'd rather not make and then break, but the distance is short enough that it doesn't change how we schedule the job.
When you call, have the door's approximate age and whether it's a single or double door ready - for a town built mostly around 1970, that usually tells us which spring size to load before we even leave. If the opener is also straining or making noise, mention that too, since a dying opener motor sometimes gets blamed on the spring and vice versa, and sorting out which is which up front saves a second visit.
Warning signs
A spring that's actually broken shows a clean gap in the coil, usually visible from the ground once the door is down - you'll often hear it before you see it, a bang like a gunshot inside the garage.
Short of that, the warning signs are a door that feels heavier than it used to, one that drifts down a few inches on its own instead of staying put, or cables that look loose at the bottom bracket.
Income levels in this part of the service area run well above the broader area average, and we mention that only because it tends to mean doors get replaced or upgraded sooner rather than run into the ground - fewer total spring failures per household, but also less tolerance for a door that's visibly sagging or noisy.
If your door is under ten years old and the spring already let go, that's worth a second look rather than a straight swap, since it can point to an opener doing too much of the lifting work the spring should be handling.
Questions
We don't quote a fixed window because traffic and the day's schedule both affect it, but Northville is only about 3 miles from our Novi location, so it's a short trip, not a special dispatch. Call and we'll give you a realistic estimate for that day.
Most Northville homes were built around 1970, which is a common era with standard torsion spring setups, and we stock those sizes regularly. Odd or older extension-spring doors sometimes need a special order, but we'll tell you upfront if that's the case.
A spring failing well before its expected cycle count usually means something else is working against it - an opener doing more lifting than it should, or a mismatched spring from a previous repair. We check the whole system, not just swap the broken part, when that pattern shows up.
Yes. Torsion springs are usually installed and wound to the same cycle life, so if one goes, the other is often close behind. We check the second spring on every call and tell you honestly if it's near the end, rather than waiting for a second breakdown.
