Garage door springs are the hardest-working part of your door system. Understanding their lifespan helps you avoid the sudden snap that leaves your car trapped inside.
The short answer
A standard garage door torsion spring lasts roughly 10,000 to 20,000 open-close cycles, which translates to about 7 to 12 years for a typical household that opens and closes the door twice a day. Extension springs tend to have a slightly shorter life, often rated near 10,000 cycles. High-cycle oil-tempered springs, which L&L installs, are rated for 20,000+ cycles and can stretch that window further.
What shortens a spring's life
Several factors accelerate spring wear. Lack of lubrication increases friction and heat at the coils, leading to premature metal fatigue. An unbalanced door forces the springs to carry uneven load, cycling one side harder than the other. Humidity and coastal salt air, common across Queens, Brooklyn, and Long Island, promote rust that weakens the steel. Frequent daily cycling — common in households with multiple drivers or attached garages used as the main entry — burns through cycles faster.
Warning signs a spring is failing
Springs rarely fail without warning. A loud bang inside the garage often signals a torsion spring has snapped. A visible gap of two to three inches in the coil confirms the break. Before failure, you may notice the opener straining, the door lifting only a few inches before reversing, or the door feeling extremely heavy when lifted manually. Any of these signs means the door is unsafe to operate and needs professional attention.
Should both springs be replaced together
Yes. Torsion springs are installed in matched pairs and experience equal cycle wear. When one snaps, the second is near the end of its life and will usually fail within weeks. Replacing only the broken spring leaves an unbalanced door and guarantees a second service visit. Replacing both restores equal tension and balanced lifting.
When to call a professional
Torsion springs carry extreme mechanical tension capable of serious injury. Spring replacement is never a do-it-yourself job. If you notice any warning sign, keep people and vehicles clear of the door and call for professional spring replacement. A trained technician safely releases tension, selects the correct wire size for your door weight, winds the new springs, and calibrates balance.
