What the Fix Involves
Most houses out here went up around 1999
Which puts the original torsion spring on the shaft right at the edge of its working life. A torsion spring is rated for a number of open-close cycles, not years, but a spring installed when the house was framed has usually seen two and a half decades of cold-season flexing by now, and it shows the same way every time: the door won't lift past a foot or two, or it drops fast on the way down because one spring let go and the other is carrying double load.
The fix is straightforward on paper
Unwind the old spring, measure the wire gauge and wind count off the shaft, and wind a matched pair back on under tension. What's not straightforward is that houses from this build era around Lake Norman of Catawba often still have the stock springs, since this isn't an area where openers and hardware get swapped out on a schedule. If the drum or the shaft itself is pitted from a quarter-century of cold-weather expansion and contraction, that gets flagged and replaced too, not just patched around.
We check both springs even when only one has broken
If the second one is close to the same age, which it almost always is on a house this old, replacing both at once costs less than a return trip later.
Booking a Visit
We run out of Cornelius, about 10 miles from Lake Norman of Catawba, so a visit here gets scheduled as a run, not a drop-in. That's not a complaint about distance - it's why we ask a few questions up front: year the door was last serviced, whether it's one spring or a full seize-up, and whether the opener still tries to run the motor against a dead spring, which burns out gears fast.
We don't keep a branch or a counter in Lake Norman of Catawba, so there's no walk-in option - every job here is booked ahead and the truck comes loaded for what you described on the phone. If the description doesn't match what we find on site, that's a second trip for the right part, which is the one real downside of covering an area this size from one location. Being specific on the phone saves that trip.
Time on the Job
A standard double-door torsion spring replacement, both springs, is a same-visit job once the truck is on site - no curing time, no parts that need to set. Where it runs long is diagnosis, not installation: on a house from this era, shaft wear, drum wear, and bent track show up together often enough that we check all three before declaring the spring the only problem.
A single broken spring with no other wear takes less time on the shaft than two springs that both need pulling, obviously, but we don't shortcut the second spring check just because the first one is the one that snapped. Cold mornings slow nothing down on our end, but they're often when the call comes in, since a spring under tension in cold metal is more likely to be the one that finally gives.
What Is on the Truck
We carry a working range of torsion spring sizes by wire gauge and inside diameter
Because a house built in 1999 doesn't necessarily take the same spring as one built in 1985, even a few miles apart. We also carry shaft collars, end bearing plates, and winding bars - the stuff that gets replaced alongside the spring when the shaft itself shows wear, which on hardware this age is common enough that we stock for it rather than special-order it.
What we don't carry for every job is a replacement opener motor
If a spring failure has already cooked a drive gear or a capacitor on the opener, that part sometimes has to be ordered rather than pulled off the truck, and we'll tell you straight if that's the case instead of guessing at a same-visit fix.
Can You Do This Yourself
A torsion spring is wound under enough tension to break a bone or worse if the bars slip, and that risk doesn't go down because the house is only 25 years old instead of 50. We'd rather you call than improvise with the wrong bar size or no bar at all.
What you can do yourself: check that the door drops slowly and evenly when disconnected from the opener by hand, with the opener unplugged. If it drops fast or uneven, that's a spring problem and it's not a DIY wind-down. If it moves smooth and slow, the spring's probably fine and the issue is elsewhere - worth knowing before you book anything.
