Garage door springs come in two main types: torsion and extension. Torsion springs sit above the door and twist to lift it; extension springs run along the sides and stretch. Both do the same job, but in different ways. Your door weighs 300 to 400 pounds, and springs handle nearly all that load. Understanding which type you have, how it works, and when it fails keeps your garage safe and your wallet intact.
Torsion springs are the workhorse of most modern garage doors in Ventura and across California. These cylindrical coils mount horizontally above the door opening on a shaft. When you press the opener button, the spring twists, storing mechanical energy that lifts the door. As it unwinds, that energy releases, making the 400-pound door feel weightless to your opener motor.
The magic is in the balance. A properly tuned torsion spring system means your opener barely works. A worn or failing spring forces the motor to compensate, burning it out faster. Springs last between 7 to 9 years under normal use (roughly 10,000 cycles). Heavy use or coastal salt air in Ventura accelerates wear. You'll notice slower opening, sagging at the center, or that telltale loud bang when one snaps.
Extension springs run parallel to the tracks on either side of your garage door. They stretch as the door closes, then contract to help lift it. They're less common than torsion springs in residential homes, but you'll see them on older installations or budget builds.
The downside: extension springs need safety cables running through them. If a spring snaps, the cable catches it and prevents the spring from whipping across your garage. Without that cable, a broken extension spring becomes a projectile. That's why code requires them, and why we always check during maintenance. If you have extension springs and haven't verified the safety cables recently, schedule a free quote to have one of our technicians inspect them.

A snapped spring is one of the most common reasons homeowners call for emergency repair. The door won't open, or it opens unevenly and jams in the tracks. You might hear a loud crack or pop. Never force the door open manually after a spring fails. That's how people get hurt.
The cost of spring replacement varies based on the type, quality, and whether both springs need replacement. A single torsion spring typically runs $200 to $400 for parts and labor. Extension springs cost less but come with more variables. For a detailed breakdown, read our guide on spring replacement costs.

You don't have to wait for failure. A professional inspection catches wear early. Look for these warning signs: slower opening speed, increased noise from the opener, or visible rust or damage on the spring itself. Ventura's coastal humidity accelerates corrosion, so springs here need more attention than those in inland areas.
Many homeowners pair spring replacement with annual garage door maintenance. A tune-up catches worn springs, misaligned tracks, and opener strain before they become expensive problems. It's the craftsman's approach to home care: fix small issues now, avoid big ones later.
For commercial applications, spring wear is even more critical. Overhead doors on warehouses and businesses see 30,000 to 50,000 cycles per year. If you manage a business in Ventura, learn more about commercial garage door maintenance and how springs factor into uptime.
Not all springs are created equal. Cheap springs fail faster. Garage Door Ventura uses commercial-grade torsion springs rated for 15,000 to 20,000 cycles. That's double or triple the lifespan of budget alternatives. The upfront cost is higher, but it's honest value. You get a door that opens smoothly for a decade without surprise repairs.
Installation matters as much as the spring itself. Torsion springs are under extreme tension. Improper installation or DIY attempts lead to injury or property damage. We've seen garage doors crash down, openers catch fire, and homeowners hurt trying to save a few hundred dollars. It's not worth it. Visit our services page to see our approach, or call 805-321-1821 to discuss your specific door.
Springs are the foundation of a smooth, safe garage door. Whether you're dealing with a snapped spring right now or planning ahead, Garage Door Ventura is here to help. We handle same-day repairs, full replacements, and maintenance to keep failures from happening in the first place.
Don't ignore warning signs. If your door is moving slowly, making noise, or you suspect spring trouble, contact us today for a free estimate. We'll inspect both springs, explain what you're looking at, and give you an honest recommendation.
How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use (roughly 10,000 cycles). Extension springs may last slightly longer, but both degrade faster in coastal areas like Ventura due to salt air and humidity. Annual inspections catch wear early.
Can I replace a garage door spring myself? No. Springs operate under extreme tension (up to 200 pounds of force). Improper installation causes serious injury or property damage. Always hire a licensed professional. The risk far outweighs any cost savings.
What's the difference between torsion and extension springs? Torsion springs twist above the door; extension springs stretch along the sides. Torsion is more common, quieter, and longer lasting. Extension springs are cheaper but require safety cables and need more maintenance.
How much does spring replacement cost? A single torsion spring runs $200 to $400 installed. Extension springs cost $150 to $300. If both springs are worn, replace both at the same time to avoid uneven door movement and future repairs.
Why did my garage door spring snap? Springs fail from age, heavy use, poor maintenance, or corrosion. Coastal salt air in Ventura accelerates rust. Regular lubrication and annual inspections extend spring life significantly.
