If your garage door suddenly won't open or feels heavier than usual, a failing spring is almost always the culprit. But not all springs work the same way. Understanding whether your door uses a torsion spring or an extension spring matters when it comes time to repair or replace it. This guide walks you through both types so you know exactly what you're dealing with.
Torsion springs and extension springs do the same job: they counterbalance your garage door's weight so the opener doesn't have to do all the heavy lifting. But they work in completely different ways.
Torsion springs sit above your garage door opening, running horizontally across the top. They twist and unwind as the door moves, storing energy like a wound-up clock spring. When you open the door, that stored energy releases, helping lift the weight. Most modern garage doors in Gaston use torsion springs because they're more precise, last longer (typically 7 to 9 years), and handle frequent operation better.
Extension springs run along the sides of your door, above the horizontal tracks. They stretch and contract as the door moves up and down, much like a slinky. When the door closes, they extend; when it opens, they contract. Older homes often have extension springs, and they're generally less expensive upfront. However, they wear out faster and require safety cables to catch them if they snap.
Knowing which type you have changes everything about the repair process. A snapped spring means your door won't open smoothly, and trying to force it can damage the opener or even injure someone. The weight of a typical garage door ranges from 300 to 800 pounds. Without functioning springs, that's all on the motor.
If you have a torsion spring, the repair is more technical. These springs operate under extreme tension, and only a professional should handle them. A single torsion spring replacement typically costs between $150 and $300, depending on the spring's quality and your door's weight. Extension springs are cheaper to replace (usually $100 to $200 per spring), but you often need two of them working together.

Look at your garage door mechanism right now. Stand inside your garage with the door closed and look up. Do you see a single large spring running horizontally across the top center of the opening? That's your torsion spring. You'll also see a metal rod running through the middle of it.
If you see two springs, one on each side running along the top of the door tracks, those are extension springs. Extension springs are easier to spot because they're more spread out.

Springs don't last forever, but regular maintenance stretches their lifespan. A tune-up every 6 to 12 months catches small issues before they become expensive repairs. We lubricate springs, check tension, and inspect cables during these visits.
If your door is over 10 years old, ask us about your spring's age during your next service. Older springs are more prone to snapping, and sometimes replacing them before failure is smarter than waiting for an emergency.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use (about 10,000 open-close cycles). Frequent use or poor maintenance can shorten this. Springs don't fail gradually; they usually snap suddenly.
Can I replace just one spring if I have two? If you have extension springs, we recommend replacing both at the same time. They wear together, and replacing only one creates imbalance and puts extra stress on the new one. It's more cost-effective long term.
Is a snapped spring an emergency? Yes. A snapped spring means your door won't open safely or may fall suddenly. Don't try to force it open. Call us right away for emergency service.
What's the cost difference between torsion and extension springs? Torsion springs generally cost $150 to $300 per spring due to their complexity and installation difficulty. Extension springs cost $100 to $200 each but often require two replacements, bringing total cost closer to torsion prices.
Why can't I replace the spring myself? Garage door springs operate under extreme tension. Improper handling during removal or installation can cause serious injury or death. Professional training and specialized tools are essential for safe replacement.
