Most homeowners don't think about their garage door springs until one snaps. Then you're stuck with a heavy door that won't open, a car trapped inside, and a real problem on your hands. The good news is that a snapped spring is fixable, and you don't have to live with a broken door for long.
Garage door springs don't just snap without reason. These components carry enormous tension, holding up a door that typically weighs 300 to 500 pounds. Springs last roughly 7 to 9 years under normal use, but several factors can shorten that lifespan.
Rust and corrosion eat away at metal over time. Here in North Chelmsford, where winters are tough and humidity fluctuates, moisture finds its way into garage spaces. Salt from roads and temperature swings accelerate wear. A spring that's never been lubricated will fail faster than one that's been maintained properly. Frequent opening and closing, especially if you use your garage door multiple times daily, also stresses the system beyond its design limits.
Sometimes a snapped spring happens because the other spring is already weak. Springs work in pairs on most residential doors. When one fails, the remaining spring carries double the load until it gives out too. This cascade effect is why replacing both springs at the same time makes sense, even if only one has failed.
Understanding which type you have matters for both safety and cost. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch to provide lift. Both designs are effective, but they fail differently.
Torsion spring failure is more dramatic and more dangerous. When a torsion spring snaps, the door can fall suddenly. The tension releases all at once, and the door becomes nearly impossible to lift manually. Extension springs are somewhat safer when they break because they're attached to cable systems that often catch the door before it drops completely.
For a detailed comparison of spring types and what they cost, our guide on garage door springs covers types, cost and when to replace them.

Spring replacement isn't cheap, but it's cheaper than replacing the entire door. A single torsion spring typically runs $150 to $300, while extension springs cost $100 to $200 each. Labor adds another $150 to $300 depending on the complexity.
Replacing both springs at once costs more upfront but saves you money and hassle. You'll pay roughly $400 to $600 for a complete job with both springs and labor included. It sounds like a lot, but consider the alternative: having a second spring fail two months later and paying for another service call and repair.

Can I open my garage door if the spring is snapped? Not safely. A broken spring means the door is essentially dead weight. Attempting to open it manually risks serious injury. The door may fall suddenly or get stuck, potentially damaging your opener as well. Always wait for professional repair.
How long does a spring replacement take? Most spring replacements take 1 to 2 hours, depending on the spring type and door condition. Simple torsion spring jobs are faster than extension spring work. We aim for same-day completion whenever possible for North Chelmsford customers.
Should I replace one spring or both? Replacing both is the smarter choice. Springs work in pairs, and if one has failed from age or stress, the other is close behind. A second failure means another service call and expense. Both springs replaced together ensures balanced lift and longer overall reliability.
What's the difference between torsion and extension springs? Torsion springs twist above the door to lift it. Extension springs stretch along the sides. Torsion systems are more efficient and safer in many cases, but both are effective. The right choice depends on your door's design and space constraints.
How can I prevent spring failure? Regular lubrication, annual inspections, and avoiding excessive use help springs last longer. Humidity and temperature swings in North Chelmsford can accelerate rust, so keeping your garage reasonably dry matters. Professional maintenance catches problems early before they become expensive emergencies.
