Garage door springs come in two main types: 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 same job. Most Fletcher homes use torsion springs because they're safer, last longer, and handle weight more smoothly. The type you have determines repair costs, replacement timelines, and which professional you need to call.
Let me cut through the confusion about garage door springs so you know exactly what's happening behind that garage door.
Torsion springs are wound coils mounted horizontally above your door opening on a metal rod. When you push your garage door opener button, the spring twists like a wrench turning a bolt. That rotational force lifts the 300-500 pound door with minimal effort from the motor.
The beauty of torsion design is balance. Springs are calibrated to your door's exact weight. A properly sized spring does roughly 95 percent of the heavy lifting. Your opener motor handles the other 5 percent. This partnership means your motor lasts longer, your door moves smoothly, and failure is usually predictable rather than catastrophic.
Torsion springs last 7 to 9 years with normal use. That's about 10,000 to 15,000 open-close cycles. Some last longer in mild climates. Fletcher's temperature swings and humid summers put extra stress on the metal, so don't assume yours will hit the upper end of that range.
Metal fatigue is the real culprit. Every single cycle causes microscopic stress. Over years, that adds up. When a snapped spring happens, your door either won't open at all or comes down hard and fast. This is genuinely dangerous. A falling garage door can injure someone or damage a car.
If you're hearing loud bangs or your door suddenly feels heavier, don't ignore it. Those are warning signs your spring is near failure. We've covered garage door spring warning signs every Fletcher homeowner should know in detail elsewhere on this site.
Extension springs run along the left and right sides of your door opening. They stretch and contract to lift the door. They're less common in residential garages these days, but you'll see them on older homes or lighter commercial doors.
Extension springs are cheaper upfront. They also take up less headroom, which matters in tight garages. The downside: they wear faster, they're noisier, and when one snaps, the other often follows within months. They're also slightly less safe because a broken extension spring can damage the cable system.
Most Fletcher homeowners with extension springs eventually upgrade to torsion springs when replacement time comes. The cost difference is smaller than you'd think, and the reliability gain is worth it.
Spring replacement cost in Fletcher ranges from $200 to $400 for a single torsion spring, installed. If both springs need replacement (common when one fails), expect $400 to $600 total. Extension springs run $150 to $300 per spring, but they rarely work out cheaper overall once you factor in labor.
These prices assume standard residential doors. Oversized doors, dual-track systems, or commercial applications cost more. The best way to know your exact situation is to schedule a free estimate from Fletcher Garage Doors.

I've been on service trucks for 15 years, and I can tell you: spring replacement is one of the few garage door jobs that genuinely requires a professional. The tension stored in a wound torsion spring is enormous. If that rod or spring breaks loose while you're working on it, you can be seriously hurt.
The tools alone cost hundreds. A proper spring winding tool, safety cables, and torque wrench aren't things sitting in your garage. More importantly, getting the tension wrong means your door won't balance. It'll bind, strain your opener, and fail again quickly.
Our team handles this every week. We get it right the first time. We also inspect your cables, hinges, and rollers while we're up there, catching problems before they become expensive. Check out our garage door tune-up guide for what other maintenance pairs well with spring replacement.
A snapped spring is obvious: your door won't budge or falls hard. But earlier warning signs matter more. Slow opening, jerky movement, visible rust on the spring, or a loud metallic ping during operation all point to springs in trouble.
Summer heat accelerates wear in this region. Winter cold makes metal brittle. If your springs are over six years old and you live in Fletcher, have them inspected before they fail. Preventive replacement beats emergency repair every single time.
How do I know if my garage door spring is about to break? Listen for unusual noises like pops or creaks. Watch for slower opening, jerky movement, or visible rust. If your door feels suddenly heavier or won't open all the way, your spring is likely failing. These warning signs usually appear days or weeks before complete failure.
Can I replace just one garage door spring? Technically yes, but it's not ideal. If one torsion spring breaks, the other is the same age and under similar stress. Replacing both at once costs only slightly more but prevents a second failure in months. Most professionals recommend replacing pairs.
How long do garage door springs really last? Torsion springs typically last 7 to 9 years under normal use. Extension springs wear faster, usually 5 to 7 years. Fletcher's weather cycles and humidity can shorten lifespan. Proper maintenance and lubrication can extend it slightly, but metal fatigue always wins eventually.
What's the difference between torsion and extension springs? Torsion springs twist to lift your door and sit above the opening. Extension springs stretch and run along the sides. Torsion springs are safer, last longer, and lift more smoothly. Most modern homes use torsion springs for these reasons.
Is a broken garage door spring an emergency? Yes. A snapped spring means your door is stuck and potentially unsafe. You can't open it without risking injury or damage. Call a professional immediately. Don't try to force the door open with your opener, as that can cause additional damage or injury.
