Torsion vs. Extension Springs in Ansonia: Which One Do You Have (And Why It Matters)
2026-08-21 7 min read
Here's what most homeowners don't realize about garage door springs: you probably can't identify which type you have without looking, and that gap in knowledge could cost you money, time, or worse. Your garage door relies on either torsion or extension springs to lift a structure that weighs 300 to 500 pounds. Get the wrong replacement, and you're calling us back within weeks.
How Torsion Springs Work
Torsion springs sit horizontally above your garage door opening, wound tightly around a metal shaft. When you open the door, they unwind slowly, releasing stored energy that counterbalances the door's weight. This makes the opener's job almost effortless. A standard residential torsion spring lasts 7 to 9 years with normal use (about 10,000 cycles). That's roughly four to five open and closes per day.
Torsion springs are the premium choice in modern homes. They're safer, quieter, and more reliable than their extension counterparts. If you had a new garage door installed in the last 15 years, you almost certainly have torsion springs.
The catch: when a torsion spring snaps, the entire load transfers instantly to your opener and cables. This is why we see so many opener failures tied directly to a snapped spring.
How Extension Springs Work
Extension springs run vertically along both sides of your door, one on each side. They stretch and compress like a slinky, storing and releasing energy as the door moves. Older homes in Ansonia and across Connecticut often feature this design because it was cheaper to install.
Extension springs wear faster than torsion. They typically last 5 to 7 years. They're also more prone to rust, especially in humid climates, and they require safety cables running through the center of each spring. These cables catch a snapped spring and prevent it from flying across your garage.
Without those cables, a snapped extension spring becomes a projectile. We've seen them punch through car windshields and drywall. This is the nightmare scenario that keeps us up at night.

Why Your Spring Type Matters for Cost and Repair
Replacement costs differ significantly between spring types. A torsion spring replacement typically runs higher because installation requires more precision and specialized tools. An extension spring replacement is cheaper but doesn't last as long, meaning you'll repeat the repair sooner.
If you schedule an estimate, we'll identify your spring type immediately and explain exactly what you're facing. Don't let a contractor tell you "both work the same." They don't.
Spring failure also looks different depending on which type you have. With torsion, your door becomes extremely heavy. Pushing it manually feels like lifting a small car. With extension springs, your door might bind or move unevenly. Both situations are unsafe and warrant immediate attention.

Which Type Should You Have?
If your home was built before 2005, you likely have extension springs. If it's newer, torsion is standard. However, previous owners sometimes mix systems during repairs, so visual inspection is the only way to be certain.
Walk into your garage and look up. Do you see a horizontal spring above the door? That's torsion. Do you see two springs running up the sides? That's extension. Take a photo if you're unsure.
Understanding your spring type also affects how you handle maintenance. Torsion springs need lubrication but rarely need adjustment. Extension springs require cable inspection and occasional balance checks. Both benefit from professional tune-ups every few years. Visit our garage door maintenance guide for seasonal care tips.
When Spring Replacement Becomes Urgent
Spring failure isn't a "wait and see" situation. The moment you notice your door getting stuck, moving slowly, or feeling heavier than usual, contact us. Delaying replacement puts stress on your opener, cables, and rollers. This cascading damage turns a single repair into a multi-system replacement.
A snapped spring in summer is inconvenient. A snapped spring in winter in Ansonia? It leaves your garage door inoperable during the season when weather matters most. Our article on winter spring failure walks through why cold months create extra stress on these components.

Frequently Asked Questions
How do I know if my spring is about to snap? Listen for creaking or popping sounds during operation. Watch for the door moving slower than usual or hanging unevenly. If you see gaps in the spring coils, that's critical damage. These signs typically appear days or weeks before total failure.
Can I replace a garage door spring myself? No. Torsion springs store tremendous energy. A released spring can cause serious injury or death. Extension springs with broken cables are equally dangerous. This is one repair that demands professional equipment and experience. Always hire a licensed technician.
Why does my extension spring replacement cost less than torsion? Extension springs require fewer specialized tools and less complex installation. Torsion springs need precise torque calculations and specialized winding bars. You're paying for precision and expertise when you replace torsion springs.
How long will my new spring last? Torsion springs typically last 7 to 9 years with standard residential use. Extension springs last 5 to 7 years. Frequency of use, climate, and lubrication all affect lifespan. Most homeowners replace springs once, maybe twice in homeownership.
Should I replace both springs even if only one snapped? Yes. If one spring has failed, the other is likely near the end of its life. Replacing both now prevents a second failure weeks later. It also costs less to replace them together than separately.
