What Local Conditions Do
Most of the houses on this side of Mecklenburg and Union County went up between 1974 and 2005
With the thickest run of building happening in the 1980s and 90s. That shows up in nine named pockets of town with the same basic garage setup: a single steel torsion spring over the header, sized for whatever door weight was standard the year the house was framed. A lot of those springs are original. Nobody replaces a spring that still works, so a thirty-year-old coil keeps turning until the day it doesn't.

But enough hard overnight drops each winter to matter for steel under tension. The spring doesn't care that the afternoon warms back up to 50. It's the overnight low that stresses the coil, and it does that every winter, year after year, on hardware that was never meant to run this long.
Put those two things together and you get a town where spring failures cluster in a predictable window instead of spreading evenly across the year
That's not true everywhere. It's true here because of what got built and when.
The Problem
A torsion spring doesn't wear out gradually the way a tire does. It holds tension for years, loses a little strength each cycle, and then one day it's carrying a door it can no longer lift. On a house built in the early 90s, that spring has had three decades of open-close cycles on hardware that was standard for its era but is now past the point where you'd call it reliable.
The real issue is that most owners don't know the spring's age, because nobody tracks it. If the house changed hands once or twice, the paperwork from the original build is long gone. So the first sign anything's wrong is usually the door stopping halfway, or a loud bang from the garage that turns out to be the spring letting go.
Here's the honest limit: if a spring has already snapped, you don't patch it. One side goes, the other side is usually close behind, and running a door on a single working spring just strains the opener and the track. At that point it's a full replacement job, both springs, sized to the actual door weight - not whatever the builder put in originally.
The Seasonal Bit
Steel contracts in the cold, and a spring under tension loses some give right along with it. In a climate band like Waxhaw's - cold enough for real overnight drops, not cold enough to stay frozen all day - the spring goes through more expansion-and-contraction cycling in a season than it would somewhere warmer year-round. That cycling is what tires out the coil faster than the rated cycle count would suggest.
This is also when you'll hear people say a spring "went in the cold." That's not folklore. A spring that was already near the end of its life, holding on through a mild fall, will often give out on the first hard cold snap of the season rather than on some random Tuesday in July. The door doesn't know the difference until the moment it does.
If your door is original to a house built in the 1980s or 90s, winter is the season to expect trouble, not to be surprised by it. That's not a sales pitch, it's just where the stress concentrates on hardware of that age in this part of the state.
Where People Go Wrong
The most common mistake is spraying the spring with lubricant and calling it fixed
Lubricant quiets a noisy spring for a week or two. It does nothing for a coil that's lost its temper from thirty years of cycling. If the spring is original to a house built before the early 2000s, oil isn't going to change the math.
The second mistake is trying to adjust tension on a spring that's already failing
This is dangerous work under the best conditions, and a spring near the end of its life can let go while someone's hands are on it. That's not a DIY afternoon, full stop.
The third is waiting
With a median household income of $89,417 across the service area, most owners here can afford to replace a spring outright rather than nurse an old one along, but plenty still wait until it snaps. A spring that's visibly stretched, rusted at the coil gaps, or making a grinding sound on every cycle is telling you something. Across roughly 15,065 owner-occupied houses in this area, a good share are sitting on hardware from the same narrow building window, which means a lot of neighbors are going to be dealing with this same decision around the same time.
