Broken Spring Replacement

A broken garage door spring is the single most common emergency in this trade — and in St. Louis, it has a season. Torsion springs do the real lifting, cycling thousands of times a year, and Midwest cold snaps make aging steel brittle: the loudest bang in your garage usually happens on the coldest morning of January. When a spring snaps, the door becomes dead weight — far too heavy to lift safely, and heavy enough to burn out an opener that tries. We replace springs in matched pairs, rated for your door's exact weight and height, and balance-test the door before we leave.

Signs you need this service

  • A loud bang from the garage, then the door won't open
  • A visible gap in the coil of the spring above the door
  • The opener hums but the door rises only a few inches
  • The door feels impossibly heavy to lift by hand
  • The door slams shut instead of gliding down

What's included

  • Matched pair replacement — both springs, same rating, same day
  • Springs rated to your door's measured weight and height
  • High-cycle spring options for busy households
  • Cable and drum inspection while the shaft is down
  • Full balance test and opener force reset
  • Old springs hauled away

Questions

Broken Spring Replacement FAQ

Why did my spring break in the cold?

Spring steel loses flexibility as temperatures drop, and a spring near the end of its cycle life is most likely to let go on the coldest nights. St. Louis cold snaps in January and February are peak broken-spring season across the metro — it's physics, not bad luck.

Can I open the door with a broken spring?

Please don't try. Without the spring, a typical door weighs 150–300 pounds, and the opener isn't built to lift it — forcing it can burn out the motor and bend the top panel. Keep the door closed and call us; spring jobs are priority dispatches.

Should I replace just the broken spring?

We recommend replacing both. Springs are installed in matched pairs and wear at the same rate — when one snaps, the other is usually near the end of its life too. Replacing both now costs far less than a second emergency visit in a few months.

How long do garage door springs last?

Standard springs are rated around 10,000 cycles — roughly 7–10 years for an average household, less for busy multi-car homes. High-cycle springs rated 25,000+ cycles are a smart upgrade if your door opens many times a day.

Is spring replacement dangerous to DIY?

Yes — genuinely. A wound torsion spring holds enough stored energy to cause severe injury, which is why this is the one garage job we tell every homeowner to leave to a technician with the right winding bars and training.
