Garage Door Spring Repair in Watertown: Torsion vs. Extension Explained
2026-08-18 7 min read
A snapped garage door spring can trap your car inside or leave you unable to secure your home. The good news: knowing which type of spring you have and why it failed helps you get the right fix fast. We'll walk you through torsion and extension springs, what causes them to wear out, and how to find a reliable repair service near you in Watertown.
What Are Garage Door Springs?
Springs are the workhorses of your garage door system. They counterbalance the door's weight so the opener doesn't strain itself lifting 400 pounds of steel or wood. Without springs in good condition, your door either becomes impossible to open manually or puts dangerous stress on your opener motor.
Most residential garage doors in Watertown use one of two types: torsion springs or extension springs. Each has a different job and different failure patterns.
Torsion Springs: The Heavy-Duty Choice
Torsion springs wind around a horizontal bar above your garage door opening. As the door lowers, the springs coil tighter, storing energy. When you press the opener button, that stored energy helps lift the door smoothly.
Torsion springs are the preferred choice for most modern homes because they last longer and operate more safely. They typically handle between 7 and 9 years of regular use before fatigue sets in. The coils fail gradually due to friction and metal fatigue, not sudden stress.
If a torsion spring snaps, you'll hear a loud bang. The door becomes very heavy. You shouldn't try to operate it. A broken torsion spring requires professional replacement because the tension is dangerous to work with.
Extension Springs: Lighter Duty, Faster Failure
Extension springs run along the sides of your door opening, parallel to the horizontal tracks. They stretch as the door closes and contract as it rises. This back-and-forth motion makes them vulnerable to fatigue cracks.
Extension springs typically last 4 to 6 years before needing replacement. They're less common now because they wear faster and pose a pinch hazard. If one snaps while the door is moving, the other spring can't hold the load.
Why Springs Fail: The Real Culprits
Metal doesn't last forever. Every time your door opens and closes, the spring experiences stress. Rust from Connecticut humidity weakens the metal from inside out. Poor lubrication increases friction and speeds degradation.
Temperature swings also matter. Watertown winters and humid summers cause metal to expand and contract, which eventually leads to micro fractures. If you haven't maintained your door in several years, a snapped spring shouldn't be a surprise.

How Much Does Spring Repair Cost?
Spring replacement cost depends on which type you need and whether both springs have failed. A single torsion spring replacement typically runs $200 to $400 installed. Extension springs cost less per spring but often need to be replaced in pairs, which raises the total bill.

When to Call for Repair
Don't wait. A failed spring means your door either won't open at all or falls too fast when you do manage to crack it open. Trying to force a jammed door stresses your opener and can cause secondary damage that costs more to fix later.
Rust, slow operation, or creaking sounds are early warning signs. Schedule maintenance before springs snap completely. Visit our complete tune-up guide to learn what regular care looks like.

Frequently Asked Questions
Q: Can I replace a garage door spring myself? A: No. Torsion springs hold dangerous levels of stored energy. Even a small mistake can cause injury or property damage. Always hire a licensed professional for spring replacement.
Q: How do I know if my spring is broken? A: You'll hear a loud bang or pop, the door becomes very heavy, or it won't open at all. Stop using the door immediately and call for help.
Q: Do both springs need to be replaced at the same time? A: If one torsion spring breaks, replace both. They wear together, so the remaining spring will fail soon after. Replacing both now saves you a second service call.
Q: How often should garage door springs be replaced? A: Torsion springs last 7 to 9 years with normal use. Extension springs last 4 to 6 years. The exact timeline depends on how often you use your door and whether you maintain it.
Q: What's the difference between torsion and extension springs? A: Torsion springs coil around a bar above the door and last longer. Extension springs run along the sides and fail faster. Torsion is safer and more reliable for most homes.
