There are two main types of garage door springs: torsion and extension. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch to do the work. Knowing which you have matters because replacement cost, safety risks, and longevity differ significantly between them.
I've spent 15 years on trucks in Eastford and surrounding Connecticut towns, and this confusion comes up every week. Homeowners often don't know what they're dealing with until something breaks. Let's clear that up right now.
Torsion springs are the industry standard for most residential garage doors today. They're mounted horizontally above the door opening on a metal rod. When your door closes, tension builds in the spring. When you open it, that stored energy unwinds and helps lift the weight.
A typical torsion spring lasts 7 to 9 years with normal use (about four to eight cycles per day). High cycle doors in commercial settings may need replacement sooner. The cost to replace a snapped spring typically runs higher than extension springs because installation requires precise balancing and special tools.
One major advantage: torsion springs are safer. If one breaks, the door doesn't suddenly drop on your car or worse, a person underneath. The door stays in place while you call for help. That's not guaranteed with extension springs, which is why I always recommend torsion for homes with kids or pets.
If you've noticed your door is harder to open manually or makes a loud bang when closing, a torsion spring failure might be imminent. Check out our detailed guide on spring replacement warning signs to learn what to watch for.
Extension springs run along each side of the door track. They stretch (extend) as the door closes, storing energy to help push it open. Most older garage doors use this design, though they're less common in new installations.
These springs are typically cheaper upfront than torsion systems. However, they wear faster under heavy use and present a safety hazard if they snap. A broken extension spring means the door can crash down suddenly. They also require safety cables (metal cords running through the spring) to catch debris if failure occurs.
Extension springs usually last 5 to 7 years. If you have them, regular maintenance and inspection are non-negotiable. Call a professional at the first sign of trouble.

Look above your door. If you see a horizontal metal rod with a spring wound around it, you have a torsion setup. If you see springs running vertically along the tracks on each side, those are extension springs.
Not sure? Don't guess. Springs are under extreme tension and can cause serious injury if you touch them the wrong way. That's why we strongly advise against DIY replacement. Our team at Eastford Garage Doors can identify your spring type and provide a cost estimate during a free inspection.
Torsion spring replacement typically costs more but offers better long-term value. Extension spring work is faster and cheaper but may require replacement sooner. A same-day estimate helps you understand your actual expense before committing.
Most jobs take one to two hours if the springs are the only issue. If rust, worn cables, or rollers need attention, add more time. We can schedule a free quote and discuss what's included so there are no surprises when we arrive.
Regular garage door tune-ups catch worn springs before they snap. A professional inspection every 12 months costs far less than emergency same-day service when your door fails during winter or summer heat. Our maintenance guide outlines what we check and why it saves money long term.
Springs don't last forever, but you can extend their life with proper care. Keep tracks clean, lubricate hinges and rollers, and let a professional handle adjustments. When a spring finally wears out, replacement is straightforward and affordable if you're prepared.

How long do garage door springs last? Torsion springs last 7 to 9 years with average use. Extension springs wear out in 5 to 7 years. Lifespan depends on cycles per day and maintenance. Regular tune-ups extend life significantly.
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 professional. DIY attempts void warranties and create liability risks.
What does a snapped spring sound like? A loud bang or crack, like a gunshot. The door may fall suddenly, get stuck, or stop moving. Call a technician immediately. Don't attempt to operate the door.
Why is torsion spring replacement more expensive? Torsion systems are more complex to install and balance precisely. They require specialized equipment and expertise. Higher cost reflects safer design and longer lifespan.
Will my door work if one spring breaks? Partially. With a torsion spring failure, the door may open slowly or feel very heavy. Extension spring breaks are more dangerous. The door could crash down without warning. Stop use and call for service right away.
