Loud bang from the garage
The classic signature of a torsion spring letting go — often heard from inside the house.
Service
Broken garage door spring? We replace them the safe way.
A snapped spring is the single most common reason a garage door quits. The door suddenly weighs 150–250 pounds instead of a few pounds, the opener strains, and the cables often follow. We replace springs in balanced pairs with cycle-rated hardware so the fix lasts.
Common symptoms
What we see on spring replacement calls.
Opener strains then stops
A single working spring cannot lift a two-spring door. The opener overworks and shuts off on the force limit.
2–4 inch gap in the spring
Visible break in the coil above the door. Do not try to lift the door manually.
Door feels extremely heavy
Even one weak spring throws the balance off enough to make lifting dangerous.
Cable dangling loose
Cables commonly fail alongside a snapped spring and need to be replaced together.
Uneven door movement
The side with the failed spring lags; the door racks and stresses the top section.
How it goes
Our spring replacement process.
Confirm door weight, drum size, and shaft length so the correct spring pair rides on the truck.
Unwind and remove the old springs, cables, and end bearings with proper winding bars — never pliers.
Install a matched pair of new springs, balance the door within a couple of pounds top to bottom, and re-tension cables.
Cycle the door and test opener force limits so nothing binds under the new tension.
FAQ
Spring Replacement questions we hear.
Why replace springs in pairs?
Two-spring doors are engineered so both springs share load. If one is at end of life, the second is close behind. Replacing only one gives a false savings and doubles the callback rate.
What is a high-cycle spring?
Standard springs are rated for 10,000 cycles (roughly 7 years of typical use). High-cycle springs are rated for 20,000 or 30,000 cycles — a common upgrade for busy families.
Is spring replacement dangerous to DIY?
Torsion springs store enough energy to break bones. They are not a DIY repair. The special winding bars, shaft, and drum alignment are also unforgiving of mistakes.
How long do new springs last?
Standard springs: about 7 years of typical use. High-cycle: 12–15 years. Extreme temperature swings and heavy insulated doors shorten these numbers.
