Garage Door Spring Types in Stratford, NH: Torsion vs. Extension
2026-05-29 7 min read
Your garage door relies on one of two spring systems to lift a 300 to 400 pound door. Torsion springs mounted above the door are costlier upfront but last 7 to 9 years. Extension springs hang on either side and cost less but wear faster. Knowing the difference helps you budget smarter and avoid surprise repairs.
In our years serving Stratford, we've seen this problem again and again: homeowners don't realize their spring type until something breaks. Then they're comparing prices blind, worried they're overpaying. This post cuts through that confusion.
Torsion Springs: The Longer Investment
Torsion springs twist and untwist to counterbalance your door's weight. They're mounted horizontally above the garage door opening on a metal rod. A single spring can handle the entire load, or two springs split the work on larger doors.
Why choose torsion? They're precise, predictable, and built to last. Most modern garage doors installed in the last 15 years use torsion systems. The spring winds tighter with each cycle, storing energy efficiently. When one fails, the door typically stays in place (safer). Repair costs run higher per spring, but you replace them less often.
The tradeoff is installation and replacement cost. A torsion spring setup involves specialized tools and trained technicians. For a same-day replacement in Stratford, expect to pay more than an extension spring job. But that higher upfront cost spreads over 7 to 9 years of reliable operation.
Extension Springs: The Budget-Friendly Choice
Extension springs stretch and contract along the sides of your garage door opening. Two springs work together to lift the load. They're simpler to install and cheaper to replace, making them common on older homes and budget garage doors.
Extension springs wear faster because they flex more intensely with every cycle. You'll likely replace them every 5 to 7 years. They also pose a safety risk: if one snaps, the door can drop suddenly. That's why modern building codes increasingly favor torsion systems.
If your extension springs fail, Stratford Garage Doors can assess whether replacement or upgrading to torsion makes financial sense. Sometimes upgrading saves money in the long run.

How to Know Which Type You Have
Look above your garage door opening. A horizontal rod with a spring wound around it means torsion. Springs hanging vertically on both sides of the opening mean extension. Unsure? Take a photo and we'll confirm during your free estimate.
Cost Comparison and When to Replace
Torsion spring replacement in Stratford typically runs $200 to $400 per spring, plus labor. Extension springs cost $100 to $200 each. However, torsion springs last longer, so your cost per year is often lower.
Most springs fail between years 7 and 9 if you have a torsion system. If your door opens slowly, makes grinding sounds, or won't stay open, your springs may be weakening. Don't wait for a snapped spring to leave you stranded. Schedule maintenance before failure.

Regional Context: Why Stratford Winters Matter
New Hampshire winters are tough on garage doors. Cold temperatures make springs stiffer and more brittle. Metal contracts in freezing weather, adding stress to worn springs. If your springs are already near the end of their lifespan, winter is when they snap.
Many Stratford homeowners discover spring problems between December and February. By then, getting a same-day appointment is harder. Consider replacing aging springs in fall to avoid winter emergencies.

Frequently Asked Questions
How long do garage door springs typically last? Torsion springs last 7 to 9 years with regular use. Extension springs wear faster, usually lasting 5 to 7 years. Lifespan depends on how often you open and close your door, maintenance, and climate conditions.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed technician. DIY attempts void warranties and create liability.
What's the difference in noise between torsion and extension springs? Torsion springs are quieter and smoother. Extension springs can be noisier and may create jerky movement. If noise bothers you, upgrading to torsion improves the experience.
Why do garage door springs snap in winter? Cold metal becomes brittle and contracts. Worn springs already stressed by years of use fail faster in freezing temperatures. Schedule replacement before winter if your springs are over six years old.
Is it cheaper to replace one spring or both? If one fails, replace both. Springs age together. Replacing only the broken one leaves you with a mismatched pair, causing uneven door movement and premature failure of the new spring.
