Garage Door Springs in Carson: Torsion vs. Extension (And Why One Fails First)
2026-06-20 A2Z Garage Doors
Let me cut through the confusion about garage door springs. Most homeowners think all springs are the same until one snaps. The truth is simpler than you'd expect: torsion and extension springs work completely differently, fail for different reasons, and cost different amounts to replace. I've been pulling broken springs off doors in Carson for 15 years, and the single biggest mistake people make is waiting too long.
How Torsion Springs Actually Work
Torsion springs sit above your garage door, wound tight as a clock spring. When you open the door, the spring unwinds and releases energy that lifts the weight. It's elegant engineering. These springs typically last 7 to 9 years with normal use (that's roughly 10,000 cycles). Torsion springs handle the heavy lifting for almost every residential garage door in Carson.
The reason they fail first: stress. Every single time your door opens or closes, that spring winds and unwinds. Metal fatigues. Eventually, the coils lose their tension, or worse, the whole thing snaps with a loud bang that echoes through your garage. When a torsion spring fails, your door becomes dead weight. You cannot open it manually. You need a professional.
Extension Springs: The Backup System
Extension springs flank your garage door, one on each side. They stretch and contract to help lift the door. Think of them like shock absorbers. They're cheaper than torsion springs but they don't carry the full load alone. Most doors have both systems working together, though some older setups rely purely on extension springs.
The problem with extension springs is that they wear unevenly. One side stretches more than the other. When that happens, your door tilts or binds. You might hear squeaking or notice the door doesn't close level. Extension springs last about 5 to 7 years. When they snap, it's usually less dramatic than a torsion failure, but your door still won't operate smoothly. If you've noticed your door hanging crooked, check our troubleshooting guide for broken garage doors to confirm what you're seeing.

Why Springs Fail: The Real Culprits
Salt air near the coast (we're close to Long Beach) accelerates corrosion. Rusty springs lose elasticity faster. Lack of lubrication is another killer. Springs need oil. If you haven't oiled yours in years, the metal dries out and becomes brittle. Temperature swings also matter. Summer heat expands the coils; winter cold makes them contract. Over time, that cycling weakens the metal.
Poor maintenance catches most people off guard. A spring that should last 8 years might fail in 5 if it's never been serviced. That's why we recommend annual tune-ups. You can read more about when to schedule your maintenance and what we check during that visit.
The Cost Reality: Torsion vs. Extension
Here's what homeowners always ask: how much does a spring replacement actually cost? Torsion springs typically run $200 to $400 per spring, plus labor. Extension springs are cheaper, usually $100 to $200 each. But labor is where the real cost sits. A professional needs to safely remove the old spring, install the new one, and balance the door. We typically charge $150 to $250 for labor on a spring job.
DIY is tempting. Do not attempt it. Springs under tension can cause serious injury. We've seen fingers broken, eyes injured, and worse. The repair estimate you get from a professional includes safety.

When to Call Right Now
If your door won't open at all, a spring has failed. If you hear a loud snap or bang, stop using the door immediately. If the door opens but moves slowly or unevenly, a spring is weakening. These situations need same-day emergency service. Don't wait.

Your garage door springs are working right now. Make them last longer with basic care, and budget for replacement when the time comes. That's what 15 years of truck work has taught me.
Frequently Asked Questions
How do I know if my garage door spring is about to snap? You'll hear squeaking or creaking, notice the door moving slower than usual, or see it hanging slightly off center. If the door feels heavier to open manually, the spring is weakening. Don't ignore these signs.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury. A compressed torsion spring can snap your wrist or worse. Always hire a licensed technician for safe, proper installation.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Lifespan depends on maintenance, climate, and how often you use the door.
Why is one spring cheaper to replace than the other? Extension springs are simpler to install and cost less to manufacture. Torsion springs require more precision and labor, so they're pricier overall.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and the door won't open at all. A worn spring loses tension gradually, making the door feel heavy and move unevenly. Both need replacement, but a snap is an emergency.
