Why springs break on the first cold morning
A torsion spring is rated in cycles — one open-and-close is one cycle — and a typical builder-grade spring carries a ten-thousand-cycle rating. A Hickory household running the door four times a day burns through that in about seven years. But the timing isn’t random: coils weakened by summers of humidity and rust contract on a December night, and the fracture that was waiting all fall finally lets go at 6 a.m. on the first genuinely cold morning of the season. Add spring pollen packing into the coils and summer storms pushing damp air through the garage, and the valley shortens a spring’s life measurably. It’s the most common repair on the route for a reason.
Why this one isn’t a DIY job
A loaded torsion spring stores enough energy to lift a two-hundred-pound wall — and it releases all of it in an instant if a winding bar slips. This is the repair that sends more DIYers to the ER than every other garage job combined. The tools are cheap and the videos look easy; the physics disagrees. A spring swap on the truck runs about an hour, and the door leaves balanced and tested.
The upgrade worth asking about
High-cycle springs — rated for twenty-five thousand cycles or more — cost modestly more than builder-grade and roughly triple the interval before the next bang. For a household that runs the door six or eight times a day, or anyone planning to stay in the house a decade, it’s the rare upsell that’s actually arithmetic. You’ll hear both prices in the quote and decide with the numbers in front of you.
