Garage Door Springs in Danvers: Torsion vs. Extension (And Why It Matters)
2026-09-14 7 min read
Most homeowners don't realize garage door springs come in two fundamentally different types, and confusing them can lead to dangerous DIY attempts or expensive repair mistakes. Your garage door in Danvers likely uses either a torsion spring or extension springs, and the difference between them affects everything from safety to replacement cost to how quickly we can get you same-day service.
The Two Spring Types: Torsion vs. Extension
Torsion springs are wound tightly around a horizontal rod above your garage door opening. They twist to release energy as your door opens and closes. These are the safer, more durable option and typically last 7 to 9 years with normal use.
Extension springs run along each side of the door tracks and stretch to help lift the weight. They're older technology, found in many Danvers homes built before the 1990s, and they fail more frequently because they work harder with less mechanical advantage.
The key difference: when a torsion spring breaks, the door stops where it is. When an extension spring snaps, the door can fall suddenly. That's why we treat a snapped spring as a genuine safety emergency.
Why Spring Type Matters for Your Danvers Home
Torsion springs handle the door's weight more evenly, which is why modern building codes favor them. If you have extension springs and they're past 7 years old, you're living on borrowed time. A snapped spring doesn't just inconvenience you. It can injure someone reaching under a falling door, damage vehicles, or trap a child.
If you've never had your springs inspected, now's the time. Learn more about garage door spring failure and what causes it to understand what warning signs you should watch for.
Identifying Your Spring Type
Look above your door from inside the garage. Do you see a tightly wound spring on a rod? That's torsion. Do you see two springs running vertically along the tracks on each side? Those are extension springs.
Don't touch them. Garage door springs are under enormous tension. A single loose coil can cause serious injury. If you're unsure what type you have, take a photo and call us at (978) 949-8566 for a quick identification.

Spring Replacement Cost and Timeline
Extension spring replacement runs $150 to $300 per spring (you typically have two). Torsion spring replacement is usually $200 to $400 per spring because they're more complex to install safely. If both springs need replacement, you're looking at $400 to $800 total, sometimes more depending on door size and condition.
We always recommend replacing both springs at the same time, even if only one has failed. The second one is likely near failure, and a single spring can't support a balanced door properly.

Why DIY Spring Repair Is Dangerous
Online videos make spring replacement look manageable. It's not. The tension in a garage door spring is equivalent to the weight of a small car. Releasing that tension incorrectly can cause the spring to whip violently, causing broken bones, deep lacerations, or worse. Even experienced mechanics use specialized tools and safety cables.

Maintenance Extends Spring Life
You can't prevent spring failure entirely, but proper maintenance helps. Keep tracks clean and lubricated. Avoid slamming the door. Have your springs inspected annually, especially if you live in the colder areas around Danvers where temperature swings stress metal faster.
Review our maintenance guide for budget-smart habits that prevent major repairs down the road.
What to Do If Your Spring Breaks
If you hear a loud bang from your garage and your door won't open, you likely have a snapped spring. Don't force the door open with the opener. The motor will strain against a dead weight and fail.
Instead, call us immediately. We offer emergency service and can often dispatch a technician the same day. Danvers Garage Doors has the springs in stock and the expertise to replace them safely.
Your garage door is one of the heaviest moving parts of your home. When springs fail, respect that weight. Call the professionals.
Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs fail sooner, often between 5 and 7 years. Lifespan depends on how frequently you use the door and whether you perform routine maintenance.
Can I replace one spring instead of both? We don't recommend it. When one spring fails, the other is usually near the end of its life. A single spring can't balance the door properly, causing uneven wear on tracks and the opener.
What's the difference in cost between spring types? Torsion springs are slightly more expensive to replace (around $200 to $400 each) but last longer. Extension springs run $150 to $300 each but fail sooner, meaning you'll replace them more frequently.
Is a snapped spring an emergency? Yes. If you have extension springs, a snapped spring means the door can fall without warning. This is a safety hazard and should be repaired immediately by a professional.
Why can't I replace springs myself? Garage door springs store extreme tension. Releasing that tension without proper tools and training can cause the spring to whip violently, resulting in serious injury. Professional installation is always safer and often required by homeowner's insurance.
