When a garage door torsion spring breaks, your door becomes a 300-pound paperweight. In our years serving Randolph, we've seen this problem again and again: homeowners hear a loud bang, try the opener, and nothing happens. A snapped spring doesn't just inconvenience you, it can damage the opener and create a safety hazard. Understanding what's happening inside your door helps you respond fast.
Torsion springs are the heavy lifters of your garage door system. Unlike extension springs that run along the sides, a torsion spring sits horizontally above the door opening. It winds up tight when the door closes, storing tremendous tension and releasing it smoothly as you open. That spring makes your 200 to 400-pound door feel featherlight.
The spring is under constant stress. Every open-and-close cycle, it winds and unwinds. Most torsion springs last 7 to 9 years with normal use, handling roughly 10,000 cycles before fatigue sets in. When a spring reaches the end of its life, metal develops micro-cracks that eventually split apart. Usually without warning.
Springs don't fail because you're using your door too much. They fail because they were engineered to fail eventually. That's not negligence, that's physics. A torsion spring that lasts 9 years is doing its job.
But certain conditions accelerate failure. Lack of lubrication causes rust and friction, shortening the spring's life by years. Temperature swings in New England hit springs hard too. Winter cold makes metal brittle, while humidity promotes corrosion. If your door sits unused for months, springs can deteriorate faster than active ones.
Poor maintenance multiplies these stresses. Check our guide on garage door maintenance in Randolph to see how simple lubrication and inspection catch problems before they snap.
The moment a torsion spring breaks, the counterbalance system fails instantly. Your garage door opener doesn't lift the door. The spring's job was to reduce the load on the opener so it only needed to lift 5 to 10 pounds of actual weight. Without that assistance, the opener tries to lift the full weight and stalls.
Some homeowners try forcing the door open anyway. Don't. An opener struggling against a broken spring can burn out its motor, which means buying a new opener on top of the spring repair. The garage door safety systems exist to prevent exactly this kind of damage.

A single torsion spring replacement runs $200 to $400 depending on the spring's size and your door weight. Labor typically adds $150 to $250. If both springs are near the same age, replacing both at once costs less per spring than replacing one now and the other in six months. We recommend asking for an estimate that clarifies whether you need one spring or two.

Some doors use extension springs instead of torsion springs. Extension springs run along each side of the door and stretch as it closes. They're cheaper to replace but less durable and slightly less safe. If you're curious whether your door uses torsion or extension springs, our safety guide explains the differences.
A broken spring isn't always preventable, but you can slow the clock. Lubricate your springs every three months with a light machine oil. Clean debris from tracks. Check for visible corrosion or gaps in the spring windings.

Spring failure is inconvenient but fixable. The key is responding fast and calling someone who gets it right the first time.
How do I know if my garage door spring is broken? A broken spring usually announces itself with a loud snap or bang. After that, your door won't open and the opener sounds strained. You may see a visible gap or separation in the spring coil above the door.
Can I drive through the door if the spring is broken? No. Without the spring's counterbalance, the door is too heavy to lift safely. Forcing it risks damaging the opener, tracks, and panels. Call for repair first.
Is a broken spring a safety emergency? Yes, treat it as one. A spring under tension can snap suddenly and cause injury. Until it's replaced, keep people and pets away from the door.
How much does a torsion spring replacement cost near me? In Randolph, most single-spring replacements run $350 to $650 including labor. Two springs cost $550 to $900 combined. Call for a free estimate specific to your door.
Can I replace just one spring if both are old? Technically yes, but we don't recommend it. Matched springs wear evenly. Replacing one old spring with one new one creates an imbalance that stresses your opener and creates uneven wear on the new spring.
