Your garage door relies on one of two spring systems to lift that heavy panel smoothly. If you don't know which type yours uses, a snapped spring can catch you off guard and cost more than necessary. Torsion springs sit above the door and twist to create lift; extension springs run along the sides and stretch. Knowing the difference helps you avoid overspending on repairs and understand what to expect when something breaks.
Torsion springs are the backbone of most modern garage doors. These metal coils wind around a horizontal shaft mounted above your door opening. When the opener activates, the springs twist tightly, storing energy that counterbalances the door's weight as it rises. They unwind as the door closes, controlling descent smoothly.
Torsion springs typically last 7 to 9 years with standard use, though that timeline shrinks in harsh climates like East Granby winters. When they fail, the door often won't budge. You'll hear a loud bang or crack, sometimes mistaking it for an explosion. That sound means the wire has snapped under tension.
The upside: torsion systems are safer and more reliable than extension springs. They're also gentler on your opener motor because they distribute force evenly. The downside: replacement requires specialized tools and expertise. This isn't a DIY job. A single torsion spring costs $100 to $250, but professional installation adds $150 to $300 more depending on difficulty.
Extension springs work differently. They're mounted horizontally on each side of your door opening, stretching and contracting like a seesaw to lift and lower the panel. When the door rises, the springs extend; when it closes, they compress back to their original length.
Extension springs are cheaper upfront (roughly $50 to $150 each) and simpler to install than torsion springs. Homeowners on a tight budget sometimes favor them. However, they wear faster in New England's humid summers and cold winters. They also pose a safety risk if pulleys fail, since a snapped extension spring can send cable and hardware flying across your garage.
Safety cables run through extension springs to contain debris if they break, but these cables can fray or snap too. Replacement still requires a professional for your own protection.

A snapped spring doesn't always mean replacing both. If one spring fails and the other is still sound, you might repair just that one. However, if both springs are the same age and type, replacing the pair together saves money long-term. Paired springs wear evenly, so fixing one while the other deteriorates creates imbalance and shortens the new spring's lifespan.

Total repair cost varies. A single torsion spring replacement runs $250 to $550 installed. An extension spring pair might cost $200 to $400 total. Labor comprises most of that expense since the springs themselves are cheap; the skill to install them safely is what you're paying for.
Walk into your garage and look above the door. Do you see a thick metal shaft with coiled springs wrapped around it horizontally? That's torsion. Do you see springs running along the left and right sides of the opening, stretching toward pulleys? Those are extension springs.

Never attempt spring repair yourself. Springs store enormous tension, and mishandling them causes serious injury. Even removing a snapped spring incorrectly can be dangerous. A professional has the right tools, knows how to safely release tension, and guarantees the job is done right.
If your door is stuck, don't force it. Prying or using the opener risks damaging the panels or stripping the motor. Learn what to do when your garage door is stuck and when emergency service makes sense.
Torsion springs cost more upfront but last longer and operate more safely. Extension springs are cheaper initially but require more frequent maintenance and carry higher safety risks. Either way, professional installation protects both your wallet and your safety.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with standard use. Extension springs wear faster, often failing within 5 to 7 years. Harsh weather and frequent opening shorten either type's lifespan.
Can I replace just one spring? Yes, but if both springs are the same age and type, replacing the pair together saves money. Paired springs wear evenly, so fixing one while the other deteriorates creates imbalance and shortens the new spring's lifespan.
What does a snapped spring sound like? A loud bang or crack, sometimes mistaken for an explosion. The door will stop moving and feel extremely heavy. Never try to open it manually; call for professional repair immediately.
Are extension springs cheaper than torsion springs? Extension springs cost less upfront, roughly $50 to $150 each versus $100 to $250 for torsion. However, professional installation balances the price difference, and torsion springs last longer overall.
