There are two main types of garage door springs: torsion and extension. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch to do the job. Knowing which one you have matters because they work differently, fail differently, and require different expertise to replace safely.
Torsion springs are the heavy hitters of the garage door world. A single tightly wound spring (or sometimes two) sits horizontally above the door on a metal shaft. When you open the door, the spring twists, storing and releasing energy to counterbalance the door's weight.
Here's why torsion matters: they're engineered to last 7 to 9 years under normal use. That's longer than extension springs. They're also safer because they're enclosed and under far less tension when you're working nearby. If a torsion spring snaps, the door won't drop suddenly onto your car or your hand.
The trade-off? Torsion springs cost more to replace. They require precision setup, the right tools, and genuine expertise. Most homeowners can't install them alone. This is where calling a professional near me becomes not just convenient but necessary.
Extension springs run along the top edge of your door on both sides. They stretch out as the door lowers and contract as it rises, pulling cables over pulleys to lift the weight. They're simpler to install and typically cheaper than torsion springs.
The downside: extension springs wear faster, usually lasting 5 to 7 years. They also carry more visible risk. If one snaps, the other side still holds the door, but the imbalance puts stress on your opener and door tracks. Over time, this can warp everything.
Extension springs also require safety cables running through them. Without those cables, a snapped spring becomes a whipping hazard. That's why we always recommend professional installation, even though the parts themselves cost less.

Walk into your garage and look up. If you see one or two tightly wound coils sitting horizontally above the door center, you have torsion springs. If you see springs running along the left and right sides of the door near the top, you have extension springs.
This matters for your wallet. A torsion spring replacement costs more upfront but lasts longer. An extension spring replacement is cheaper initially but you'll likely need service sooner. When calculating long-term value, torsion often wins, though it depends on your door's weight and how often you use it.

This cannot be overstated: spring replacement is dangerous. Torsion springs operate under 400 to 800 pounds of tension. Extension springs add another layer of hazard with their pulleys and cables. One slip, one wrong measurement, and you're facing serious injury.
That's why we recommend calling a professional for spring repair in Arcadia rather than going the DIY route. A professional will measure your door weight, select the correct spring, install it properly, and test the balance. Same-day estimates are available.
Torsion spring replacement typically runs $200 to $400 per spring plus labor. Extension springs cost $150 to $250 per spring plus labor. Total job time is usually 1 to 2 hours for an experienced technician. If you need a same-day service, Garage Door Arcadia can help.

How do I know if my spring is about to fail? Listen for creaking or popping sounds. Look for visible gaps or kinks in the coil. If your door feels heavier than normal or won't stay open, a spring is likely weakening. See our warning signs guide for a full checklist.
Can I replace just one extension spring? Technically yes, but we don't recommend it. Springs work in pairs. If one has failed, the other is near the end of its life too. Replacing both ensures balanced operation and prevents premature wear on your opener and door.
Which spring type is quieter? Torsion springs tend to be quieter because they're enclosed and above the door. Extension springs can create more noise when the door opens and closes because the cables and pulleys create friction and vibration over time.
How much does an emergency spring repair cost? Emergency or after-hours spring service typically costs 25 to 50 percent more than daytime rates. Same-day estimates are free. Check our emergency repair cost breakdown for exact pricing.
What should I do if my spring snaps while the door is opening? Stop using the door immediately. Do not force it up or down. Call a professional. A snapped spring creates an off-balance door that can damage your opener or tracks. We offer same-day emergency calls throughout Arcadia and surrounding areas.
