A customer called last Tuesday asking why we quoted him differently for his spring repair than a competitor down the street. Turns out, they were talking about two completely different types of garage door springs. That's the moment I realized most homeowners in Swampscott don't know the difference between torsion and extension springs, let alone which one they have. Here's the truth: your garage door spring type matters hugely for safety, cost, and longevity. Understanding what's above your door will save you money and headaches.
Torsion springs are the workhorses. They're mounted horizontally above your garage door opening, and they twist and unwind to lift the weight. Think of them like a wound-up clock spring that slowly releases energy. Most modern homes in Swampscott and the surrounding North Shore area use torsion springs because they're more durable, safer, and last longer.
Here's what makes them stand out: a single torsion spring can handle doors up to 400 pounds. They're precise, predictable, and when they fail, they typically fail straight (though a snapped spring is still a serious problem). If you hear a loud bang from your garage and your door suddenly feels heavy, you likely have a broken torsion spring on your hands.
The lifespan is solid too. Quality torsion springs last 7 to 9 years with normal residential use, sometimes longer if you maintain your door well. That's a real advantage over extension springs, which typically need replacement sooner.
Extension springs work differently. They're mounted along the sides of your door opening and stretch and contract like a rubber band. When you open the door, they extend. When you close it, they contract back. Older homes and budget installations sometimes use these.
Extension springs have two major drawbacks. First, they wear faster than torsion springs, often needing replacement every 5 to 7 years. Second, if one breaks, the other side is working alone, which throws your door out of balance. That imbalance can damage your opener and create a safety hazard. Safety cables run through the center of extension springs for this reason, but they're still considered riskier.
If your garage door installation happened more than 15 years ago, you likely have extension springs. If you're unsure which type you have, don't guess. A quick call to us at (781) 343-7411 can clear it up in seconds.

Here's where spring type impacts your wallet. A torsion spring replacement costs more upfront than extension springs, but you're replacing them less often. Over a 20-year period, torsion usually wins on total cost. Plus, if your opener is relatively new, torsion springs cause less wear and tear on the motor.
When you need an estimate for garage door springs in Swampscott, the technician will check your existing setup, measure your door weight, and recommend the right type and size. Never assume you can swap spring types without professional input. The wrong spring size can burn out your opener or worse.

A snapped spring doesn't just stop your door from opening. It puts tremendous strain on your garage door opener motor, which will burn out if you keep trying to open the door. Worse, a broken spring means the door loses its counterbalance and becomes a safety risk. Heavy doors can crash down unexpectedly, especially if you have an older opener.
If you suspect a snapped spring, stop using the door immediately. Don't try the opener. Contact a professional for same-day repair service. We serve Swampscott and neighboring communities with emergency response.
If you want to prevent spring failure altogether, follow a solid maintenance routine. Lubricating springs, checking for rust, and listening for unusual sounds can catch problems early.
The easiest way to tell: look above your door. Torsion springs sit horizontally on a shaft above the opening. Extension springs run along the sides. If you can't safely see or you're unsure, don't take the risk. Our team at Swampscott Garage Doors can identify your springs and recommend the right course of action.

How long do garage door springs actually last? Torsion springs typically last 7 to 9 years under normal residential use. Extension springs wear faster, usually needing replacement every 5 to 7 years. Lifespan depends on usage frequency, maintenance, and climate exposure.
Can I replace a garage door spring myself? No. Spring replacement is dangerous. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed technician for spring work.
What's the difference in cost between torsion and extension springs? Torsion springs cost more upfront, typically $200 to $400 per spring including labor. Extension springs run $150 to $250. However, torsion springs last longer, making them more economical over time.
Why did my spring break without warning? Springs weaken gradually over years due to metal fatigue. Winter cold, humidity, and regular use all accelerate wear. Eventually, the metal simply snaps. Regular maintenance can catch weakness early.
Do I need to replace both springs at once? Yes. If one spring fails, the other is near the end of its life too. Replacing both ensures balanced operation and prevents quick failure of the second spring shortly after.
