Garage Door Springs in Coventry: Torsion vs. Extension (And Why It Matters to Your Wallet)
2026-09-08 7 min read
Garage door springs come in two main types: torsion and extension. A snapped spring means your door won't open safely, and the type you have determines your repair cost and timeline. Understanding which one you own helps you make smarter decisions before calling for help.
What's the Difference Between Torsion and Extension Springs?
Torsion springs sit above your garage door, running horizontally across a metal rod. They twist to counterbalance your door's weight as it opens and closes. Most modern homes in Coventry use torsion springs because they're durable, reliable, and last longer.
Extension springs hang vertically on either side of your door tracks. They stretch and contract like a rubber band to lift the door. These are less common in newer installations but still appear in older homes and lighter doors. Extension springs tend to wear out faster and create more safety concerns if they snap.
The key difference: torsion springs twist under tension. Extension springs pull under tension. This affects how they fail, how much they cost to replace, and how quickly you need professional help.
Why Your Spring Type Matters for Cost and Safety
A snapped torsion spring typically costs between $200 and $400 to replace, depending on your door's weight and spring quality. Extension springs run $150 to $250 because they're simpler to manufacture and install.
But safety is the real issue. When an extension spring breaks, it can whip around and cause injury. Torsion springs are safer when they fail because the rod contains most of the force. If you have extension springs and one snaps, treat it as urgent.
Most homeowners don't know which type they have until something goes wrong. If you're unsure, look above your door. See a horizontal rod with coils wrapped around it? That's torsion. See springs hanging on the sides? That's extension.

How Long Do Springs Last?
Both types last roughly 7 to 9 years under normal use. That's about 10,000 to 15,000 open-close cycles. Your actual lifespan depends on climate, humidity, and maintenance. Connecticut winters and moisture can corrode springs faster, shortening their life by a year or two.
Garage Door Coventry recommends inspecting springs annually during your regular maintenance routine. Look for rust, visible gaps in coils, or a door that feels unbalanced when opening. These are early warning signs before a complete failure.
Replacing springs as a preventive measure before they snap saves you emergency fees and potential safety risks. If you haven't had your springs serviced in over five years, a free inspection is worth scheduling.
What Happens When a Spring Snaps?
Your garage door becomes very heavy and dangerous to operate manually. The opener will strain and may burn out trying to lift the door. You'll hear a loud bang or crack when the spring breaks, often sounding like a gunshot in your garage.
Never try to force your door open after a spring failure. The remaining spring or cable can snap under sudden stress, causing injury. Call a professional instead. We offer same-day estimates and can often complete repairs within hours, not days.

Torsion Springs: The Modern Choice
Torsion springs are the industry standard today. They're more efficient, last longer, and distribute force more evenly across the door. If you're replacing springs and have a choice, torsion is the smarter long-term investment.
One spring usually counterbalances the entire door weight, so a torsion system is simpler. Fewer moving parts mean fewer failure points. They also handle temperature changes better than extension springs, which makes them ideal for Coventry's seasonal swings.

Extension Springs: Older Homes and Light Doors
Extension springs still appear in homes built before 2000 or in doors under 300 pounds. If your house is older, you likely have extension springs. They're cheaper upfront but require safety cables running through them to contain fragments if they snap.
Check if safety cables are installed alongside your extension springs. If not, this is a safety gap worth fixing soon. A broken spring without cables is a genuine hazard.

Frequently Asked Questions
Q: Can I replace just one spring if I have two? A: No. Springs wear in pairs and age together. Replacing one leaves the other ready to fail within weeks. Replace both at the same time to avoid repeat service calls and expense.
Q: How do I know if my spring is about to snap? A: Look for rust, visible cracks in the coils, or a door that feels heavier than usual on one side. A creaking sound during operation also signals wear. These mean replacement is due soon.
Q: Are torsion springs always better than extension springs? A: For modern homes and safety, yes. Torsion springs last longer and are safer when they fail. Extension springs work fine on light doors but come with more maintenance and safety considerations.
Q: What's the difference between spring replacement and spring repair? A: Springs can't be repaired once they crack or snap. Repair refers to adjusting tension or lubricating a healthy spring. A broken spring requires full replacement.
Q: How much does a spring inspection cost? A: Most companies offer free inspections. Call us at (860) 891-3631 to schedule yours today. We'll assess both springs and give you an estimate if replacement is needed.
