Torsion vs. Extension Springs in Hamilton: Which Does Your Garage Door Need?
2026-06-27 7 min read
Here's what most homeowners don't realize about garage door springs: your door doesn't have just one type, and the wrong replacement choice can cost you hundreds of dollars. Garage doors in Hamilton rely on either torsion springs or extension springs to lift that 300-400 pound door smoothly. Understanding which system you have matters when repairs arise, because mixing them up leads to unsafe installations and wasted money.
What Torsion Springs Do (And Why They're Common)
Torsion springs sit above your garage door, running horizontally across the header. They work by twisting and storing mechanical energy as your door closes, then releasing that energy to help lift the door open. Think of them like a wound-up clock spring that powers the entire operation. See our guide on emergency garage door service in hamilton, wa: what to do when yours gets stuck.
Most homes built in the last 30 years use torsion springs. They're more durable, take up less space, and distribute weight more evenly across your door frame. A quality torsion spring lasts 7 to 9 years with normal use, which translates to roughly 10,000 to 15,000 cycles. When one snaps, the sound is unmistakable: a loud crack that echoes through your garage, sometimes followed by your door slamming shut on its own.
The trade-off? Torsion springs cost more upfront than extension springs, and installation requires specialized tools and knowledge. This is not a DIY job. The tension stored in these springs is dangerous, and improper handling can cause serious injury. Read about garage door springs in hamilton, wa: when to replace and why it can.
Extension Springs: The Older Alternative
Extension springs hang vertically on each side of your garage door opening. They stretch as your door closes, storing energy in the extended coil. When the door opens, they contract and help push it up.
Older homes and budget installations often use extension springs. They're cheaper to buy and easier to install than torsion springs, which appeals to some contractors. However, they wear faster, require more frequent adjustment, and don't handle heavy doors as smoothly. If your garage door feels jerky or unbalanced during operation, worn extension springs might be the culprit.
Extension springs also need safety cables running through them. If a spring snaps, the cable catches it and prevents the spring from whipping across your garage. Without that cable, a snapped spring becomes a projectile hazard.
How to Tell Which Type You Have
Walk into your garage and look above the closed door. Do you see a single horizontal spring running left to right? That's torsion. See two springs hanging on the sides, running parallel to your door tracks? Those are extension springs.

Cost Differences and Replacement Timing
Torsion spring replacement typically costs 15 to 30 percent more than extension springs, depending on your door's weight and spring quality. But here's the catch: you usually replace torsion springs in pairs, even if only one snaps. This prevents imbalance and premature failure of the remaining spring. Extension springs are often replaced individually, which seems cheaper upfront but leads to uneven wear.
If your garage door springs are nearing the end of their lifespan, don't wait for a snapped spring to strand you with a non-functional door. Our garage door springs maintenance guide walks you through warning signs to catch early.

Frequently Asked Questions
What happens if I only replace one torsion spring instead of both? Replacing a single torsion spring creates imbalance, causing the door to open unevenly and the remaining spring to wear faster. We always replace them in pairs to ensure even lift and extend the lifespan of your entire system.
Can I use extension springs on a door that originally had torsion springs? No. Torsion and extension springs are designed for different door weights and frame configurations. Mixing them compromises safety and balance. Always match your original spring type.
How much do garage door springs cost to replace in Hamilton? Torsion spring replacement typically ranges from 250 to 450 dollars per pair, plus labor. Extension springs run 150 to 250 dollars. Final cost depends on your door weight and spring quality. Call us for an exact estimate.
Is a snapped garage door spring an emergency? Yes. A broken spring prevents safe door operation and leaves your home exposed. Contact us immediately for same-day service. Do not attempt to open or close the door manually.
How long do garage door springs last? Quality torsion springs last 7 to 9 years with typical use. Extension springs often wear out faster, sometimes within 5 to 7 years, depending on your door's weight and opening frequency.
