Garage door springs are the unsung heroes holding up your door. When one snaps, your door won't budge, and you're stuck. Let me cut through the confusion: there are two main types (torsion and extension), they fail predictably around 7 to 9 years, and the cost to replace them varies based on which type you have and local labor rates.
The type of spring your door uses depends on your door's design and weight.
Torsion springs sit above the door opening on a horizontal rod. They twist (torque) to lift the weight as the door opens. These are the stronger, more durable option and the one we install on most modern garage doors in Scituate and the surrounding South Shore area. A torsion spring typically lasts longer because it distributes force more evenly. If you have a heavier door or a two-car garage, torsion is almost always your setup.
Extension springs hang vertically on both sides of the door and stretch to lift it. They're common on lighter, single-car doors or older installations. They wear faster because the pulling motion creates more friction and stress over time. Extension springs are cheaper upfront but often need replacement sooner.
How do you know which you have? Look above your door opening. If you see a horizontal rod with a tightly coiled spring in the middle, that's torsion. If you see springs running along the side tracks, those are extension springs.
Springs don't just break without warning. They fatigue over thousands of opening and closing cycles. Every time your door goes up and down, the spring stretches or twists slightly. After 7 to 9 years of normal use (roughly 10,000 to 15,000 cycles), the metal loses its ability to spring back.
A snapped spring won't let your garage door open, period. The door's weight transfers entirely to your opener motor, which can't handle it alone. You'll hear a loud bang when it happens, usually during morning or cold weather when metal is more brittle.
Cold temperatures accelerate this. In Scituate winters, metal contracts, making springs more prone to failure. I've had customers call on the coldest day of the year with a snapped spring. It's frustrating but preventable with routine maintenance. Check your springs visually once a season, and if you see rust, unevenness, or gaps in the coils, call us before it breaks.

Let's talk money honestly. A single torsion spring replacement typically runs $150 to $300 for the part and labor combined. If both springs need replacing (which we often recommend since the second spring is aging too), expect $250 to $500 total.
Extension springs cost less per unit, usually $100 to $200 for one or both, but they break more frequently, so you'll end up spending more over time.
Labor varies. In Scituate, where we operate, a technician visit for spring replacement takes about an hour. You'll pay somewhere in the $150 to $250 range for that time, depending on complexity and whether it's same-day emergency service.
Emergency calls outside business hours cost extra, usually 50% more. If your spring snaps on a Sunday or late evening, that premium applies. It's worth budgeting for because a broken spring leaves you without access to your garage.
Why the variation? Some doors have multiple springs, some have older hardware that's rusted and harder to remove, and some require additional safety measures. That's why we always provide a free estimate before starting work. See our breakdown of garage door cost factors for more on what moves the needle.
I'll be direct: don't replace springs yourself. They're under enormous tension. A torsion spring holds the equivalent weight of a car. If you slip during removal, you risk serious injury.
We've seen customers try to save a few dollars and end up in the emergency room. It's not worth it. Spring replacement requires specialized tools, knowledge of spring tension, and insurance coverage if something goes wrong.
Call us for a free estimate near you. We'll inspect both springs, tell you if one or both need replacement, and quote you fairly. No surprises. No upselling.
Most failures are preventable. Lubricate your springs with garage door lubricant (not WD-40) twice a year. Keep the area around springs clear of debris. And if you notice any signs of wear, don't wait until it snaps.

How long do garage door springs last? Most springs last 7 to 9 years with normal residential use. That's roughly 10,000 to 15,000 open/close cycles. Commercial doors that cycle more frequently may need replacement sooner. Proper lubrication and maintenance can extend lifespan slightly.
Can I drive my car under a garage door with a broken spring? No. Don't force the door open or closed. A broken spring means the opener can't support the weight safely, and the door could drop suddenly, causing injury or property damage. Call a professional.
Is a snapped spring covered by homeowner's insurance? Usually not. Springs are wear items, not damage from weather or accidents. Check your policy, but most insurance doesn't cover spring replacement. That's why we offer straightforward pricing and same-day estimates.
Do both springs need to be replaced at once? Not always, but we recommend it. If one spring is 7+ years old and snaps, the other is aging similarly. Replacing both at once saves you a second service call and keeps balanced tension on your door. Ask about this during your estimate.
What's the difference between a loud bang and a spring snap? A loud bang usually means a spring snapped. You'll also notice the door won't open, or opening it is extremely difficult. If the door still works but sounds odd, it could be loose hardware or track issues. Call for a diagnosis.
