Torsion vs. Extension Springs in Hopkinton: Which Type Do You Have?
2026-07-04 7 min read
Most homeowners in Hopkinton don't know which type of garage door springs they have until one breaks. The two main types are torsion springs, which wind around a shaft above the door, and extension springs, which stretch along the sides. Knowing the difference affects repair cost, safety, and how long your system lasts. Let's cut through the confusion so you understand what's holding your door up.
Torsion Springs: The Standard Choice
Torsion springs are the most common type in modern homes. They sit horizontally above your garage door opening, mounted to a steel shaft. When you open the door, the springs twist (torsion means twisting) to counterbalance the door's weight. This makes the opener's job much easier and gives you smoother, more controlled operation.
Here's the practical part: torsion springs last 7 to 9 years under normal use, though that depends on how often you open and close the door. If you operate your garage door five to eight times daily, expect springs to wear out faster. They're engineered to handle roughly 10,000 cycles before fatigue sets in.
Torsion springs are safer than extension springs because they're under constant tension inside a steel tube. If one snaps, the broken pieces stay contained. The door won't crash down unexpectedly. This is why building codes now favor torsion systems in residential garages.
Extension Springs: The Older Design
Extension springs hang vertically on both sides of the door frame. They stretch and contract as the door moves up and down. Many older Hopkinton homes still use this setup, and they work fine when properly maintained.
The catch: extension springs require safety cables running through the center of each spring. If a spring snaps without that cable in place, the spring can whip across the garage and cause serious injury. That's why modern installations switched to torsion. Extension springs also tend to wear out faster, typically lasting 5 to 7 years because the constant stretching fatigues the metal.
If you have extension springs and one snaps, you'll notice the door feels unbalanced and heavy on one side. That's a sign to call for service right away.
Cost and Replacement Differences
Torsion spring replacement usually costs more upfront than extension springs because they require precise tension adjustment. A technician must calculate the exact spring size and wind tension for your door's weight. Get this wrong, and the door won't operate safely.
Extension spring replacement is simpler mechanically but riskier if you attempt it yourself. Both types need professional installation. We've written more detail on garage door spring costs and when to replace them in Hopkinton if you want to dig deeper into pricing.

How to Tell Which Type You Have
Walk into your garage and look above the door. Do you see a horizontal metal shaft with springs coiled around it? That's torsion. Do you see springs running vertically down the sides of the door opening? That's extension.
Torsion springs are thicker and more compact. Extension springs look like long coils running parallel to the door tracks. If you're unsure, take a photo and call us. We can identify your system over the phone and give you an honest cost estimate without the guesswork.
When a Spring Fails
A snapped spring won't let your door open. The opener will strain, and you'll hear grinding or clicking sounds. Some doors won't budge at all. Never force a broken spring by trying to open the door manually or with the opener. You risk damaging the opener, the door, or worse, hurting yourself.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (5 to 8 door cycles daily). Extension springs wear faster, lasting 5 to 7 years. Lifespan depends on climate, humidity, and how frequently you operate the door.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools, knowledge of tension and torque, and carries serious injury risk. Improper installation can damage your opener or cause the door to fall unexpectedly. Always hire a professional.
What's the average cost to replace garage door springs in Hopkinton? Torsion spring replacement typically costs between $200 and $400 per spring, including labor. Extension springs run $100 to $250 per spring. Exact pricing depends on your door's weight and spring specifications. We provide free estimates.
Do I need to replace both springs at the same time? Yes. Springs wear at the same rate. Replacing only one creates imbalance and accelerates wear on the replacement. Always replace both springs together for even operation and safety.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely stops door operation. A worn spring weakens gradually, causing the door to feel heavier or the opener to strain. Both need immediate professional service.
