Garage door springs fail without warning, and when they do, your door won't open. The two main types are torsion and extension springs. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Both eventually snap, but knowing which one you have and what to expect helps you make smart decisions fast.
Torsion springs are the heavy hitters of garage door systems. A single spring or pair of springs winds up like a clock and stores enormous mechanical energy. When your opener signals the door to rise, that coiled tension releases smoothly, lifting a 300+ pound door with minimal effort. They're durable, lasting 7 to 9 years with regular use, and they fail less often than extension springs.
Extension springs work differently. They hang on both sides of the door and stretch as it closes, then contract to help lift it open. Because they're under constant tension, they wear faster. You'll typically replace extension springs every 5 to 7 years. They're also noisier and more prone to sudden snapping, which is why many homeowners and contractors prefer torsion setups.
A snapped spring is obvious. Your door won't budge, and you'll hear a loud bang or twang from the garage. But springs often fail gradually. Watch for these warning signs: your door feels heavier than usual, the opener struggles or cycles on and off, or the door moves unevenly. If you see rust or oil leaking from the spring housing, don't wait. A weakening spring can snap any day.
If your door won't open at all, our garage door repair guide covers troubleshooting steps to help you identify whether it's a spring issue or something else.

Springs hold thousands of pounds of tension. A snapped spring can cause serious injury or death if mishandled. Cables, pulleys, and the door itself can come crashing down. Even experienced mechanics use specialized tools to safely wind and secure new springs. This isn't a job for a weekend project or an amateur handyman.
Garage Door Laconia technicians have the right equipment and training. We replace springs correctly, test your entire system, and make sure everything balances. That peace of mind is worth the cost.
Springs last longer with basic care. Keep the tracks clean and lubricated with a silicone spray (not WD-40). Check cables and pulleys for wear. Have a professional inspect your system annually. If you live near the lakes or in humid areas, moisture and salt air accelerate rust, so regular maintenance is even more critical. Our lakefront maintenance guide covers seasonal care for waterfront homes.
Most importantly, don't ignore warning signs. A spring that's starting to fail will give you hints before it snaps completely. Catching it early means a planned service call instead of an emergency repair on a weekend or holiday.

How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs wear faster, usually 5 to 7 years. Lifespan depends on use frequency, maintenance, and climate conditions. Regular lubrication and inspections extend life.
Can I replace just one spring? Yes, but we recommend replacing both at the same time. If one spring fails from age or wear, the other is likely close behind. Replacing both ensures balanced operation and prevents a second failure weeks later.
How much does spring replacement cost in Laconia? Total cost ranges from $400 to $600 for parts and labor. Torsion springs cost more than extension springs, but last longer. We provide free estimates before any work begins.
What happens if a spring snaps while the door is open? The door won't close and the opener won't operate safely. Never try to force it. Call a professional immediately. A snapped spring means the door has no mechanical support and could fall unexpectedly.
Is spring replacement an emergency? Not always, but it should be treated as urgent. Schedule service within 24 hours to avoid being locked out of your garage. We offer same-day appointments when possible.
