Why It Happens Here
Most garages in Kenmore went up around 1984, and the door hanging in that opening is almost always a steel sectional door - either a single 9-foot or a double 16-foot, built with the flat or light wood-grain stamped panels that were standard for that decade. Those doors were matched at the factory with torsion springs sized for their weight class, wound tight on a steel shaft above the opening. That hardware doesn't fail because it's old in a vague sense; it fails because a torsion spring is rated for a set number of open-close cycles, and a spring installed around 1984 has usually burned through that count well before now.
The region's cold, moderate climate adds to the wear. Winter cold makes spring steel stiffer and more brittle right as the metal is already fatigued from three-plus decades of cycling, which is why a lot of these springs let go on the coldest mornings of the year rather than in July. If your door is original to a house from that era and nobody's touched the springs, you're not dealing with a random break - you're dealing with hardware that was always going to reach this point.
Stocked Parts
We carry torsion springs in the wire gauges and wind lengths that match the 7-foot and 8-foot openings common on houses built through the 1980s and 90s in this area - the size range that covers most of what's actually on the ground in Kenmore. That includes standard single-spring setups for lighter single doors and matched dual-spring sets for the heavier double doors from the same build years.
What we don't carry on the truck is anything built for the old extension-spring systems from well before that housing wave, or the oddball specialty torsion springs sized for very heavy custom or oversized doors. If your door turns out to need one of those, we'll tell you straight that it's a special order rather than pretend we can swap it same-visit. For the typical 1980s steel sectional door, though, the right spring is usually already on the truck.
What the Repair Takes
The job starts with measuring the broken spring
Wire diameter, coil length, and inside diameter - against the door's actual weight, not just guessing from what's hanging there, since a lot of these doors have had an opener added or a panel replaced since 1984 that changes the balance. We wind the new spring or springs to the right tension, check both cables and the drums they wrap around for wear, and run the door through a full manual balance test before we touch the opener.
A door that's been running on a weak or broken spring for a while often has a stretched cable or a worn roller that gets replaced in the same visit
Since leaving those alone just means a second call later. The honest limitation here: if a door needs a specialty spring size we don't stock, or if the torsion shaft or drums are damaged beyond reuse, that part of the job may need to wait on an order rather than finish in one visit.
The Cost of This Job
What a spring job runs depends mostly on three things: whether it's one spring or a matched pair, the wire gauge and size the door actually needs, and whether anything else - a cable, a drum, a bent track - gets found and fixed at the same time. A single door with one spring is a smaller job than a double door running two torsion springs under more tension.
We don't publish a flat number here because the honest answer changes with the door in front of us, and quoting one figure before we've measured the spring and checked the hardware would be a guess, not a price. What we can tell you is that spring work on these 1980s-built steel sectional doors is routine for us - it's one of the more common calls we get from this part of the service area.
How It Shows Up
The most obvious sign is a door that won't budge, or that an opener strains and reverses instead of lifting. A loud bang from the garage, especially one that happens with no one touching the door, is usually the spring itself letting go rather than something slower failing.
Before a full break, you'll often see smaller warnings: the door feels heavier to lift by hand than it used to, the cable near the bottom bracket looks slack or frayed, or the door closes unevenly, dropping faster on one side. On a double door with two springs, one can fail while the other still holds some tension, so the door might still move but badly - jerking, tilting, or stalling partway. Any of these is worth a call before the second spring goes and the opener motor takes the strain it isn't built for.
