Garage Door Spring Types in Glastonbury: Torsion vs. Extension Explained
2026-06-24 7 min read A2Z Garage Doors
If you've ever dealt with a stuck garage door, a snapped spring might be the culprit. Understanding whether your door uses torsion or extension springs helps you budget for repairs, avoid overpaying, and make smarter decisions about replacement timing. The two spring types look different, work differently, and cost differently, so knowing which one you have matters before you call for a quote.
What Are Garage Door Springs?
Garage door springs are the hardworking counterbalance system that makes your 300 pound garage door feel lightweight when you open it. Without them, your opener motor would burn out in weeks trying to lift all that weight alone.
Two main types do this job: torsion springs and extension springs. Each has strengths, weaknesses, and price tags that affect your wallet over time.
Torsion Springs: The Stronger Choice
Torsion springs mount horizontally above your garage door opening. They twist and unwind to lift the door, storing energy like a wound clock spring. Most modern homes built in the last 20 years use torsion springs because they're safer, quieter, and last longer.
A typical torsion spring lasts 7 to 9 years with average use (one to two openings per day). They cost more upfront (usually $200 to $400 per spring, plus labor) but deliver better performance and fewer headaches down the road.
Torsion springs are also safer. If one snaps, the door doesn't suddenly crash down because the second spring holds the load. This matters when kids, pets, or parked cars are nearby.
Extension Springs: The Budget Option
Extension springs run vertically along the sides of your garage door frame. They stretch and contract to counterbalance the door. Older homes in Connecticut often have these, and they're cheaper to replace initially (around $100 to $250 per spring).
The tradeoff? Extension springs wear out faster. They typically last 5 to 7 years, not 7 to 9. They're also louder, jerkier, and require safety cables to prevent them from snapping and whipping across your garage if they fail.
If a snapped spring leaves you stranded, extension spring failures tend to be more dramatic and dangerous for this reason.

Spring Failure: Cost Comparison
Replacing one torsion spring costs more upfront but spreads savings over time because you'll replace it less often. Replacing two extension springs might feel cheaper at the moment, but if you need service again in 5 years instead of 8, those savings disappear fast.
Most homeowners don't think about this math until their door stops working. A single snapped spring leaves your door stuck, your opener stressed, and your schedule disrupted.
That's why learning when to repair versus replace your entire system makes financial sense. Sometimes replacing both springs and upgrading to torsion pays for itself in convenience and durability.
Identifying Your Spring Type
Walk into your garage and look above the door. Do you see a single horizontal bar with coils wrapped around it? That's a torsion spring. Do you see two vertical springs running alongside the door frame on both sides? Those are extension springs.

Why Spring Type Matters for Your Budget
Choosing between repair and replacement isn't just about the broken spring. It's about your long-term costs and safety. If you have extension springs and they're approaching 6 or 7 years old, replacing them with torsion springs might cost more today but saves you emergency service calls and stress later.

Frequently Asked Questions
How do I know if my garage door spring is broken? Listen for loud bangs or cracks. If your door won't open, opens slowly, or feels lopsided, a snapped spring is the likely cause. Never force it open. Call a professional immediately.
Can I replace just one spring? Technically yes, but both springs wear together. Replacing one leaves the other near failure. Most pros recommend replacing both at once to avoid a second service call in months.
How much does a spring replacement cost in Glastonbury? Torsion spring replacement typically runs $300 to $500 per spring plus labor. Extension springs cost $150 to $350. Labor varies by complexity. Call for a firm estimate.
How long do garage door springs last? Torsion springs last 7 to 9 years. Extension springs last 5 to 7 years. Frequency of use and climate affect actual lifespan.
Is spring replacement an emergency service? Yes. A broken spring leaves your door stuck and your opener at risk. We offer same-day emergency repairs across Glastonbury and nearby areas.
