Garage Door Springs in Mission Viejo: Torsion vs. Extension, Costs, and When to Replace
2026-06-25 7 min read A2Z Garage Doors
Garage door springs are the hardest working parts on your door, and when one snaps, your garage won't budge. There are two main types: torsion springs that wind and unwind above the door, and extension springs that pull from the sides. Knowing which one you have, why they fail, and what a replacement costs helps you make the right call fast.
How Garage Door Springs Actually Work
Your garage door weighs between 300 and 700 pounds. That's not something you want crashing down on your car, your leg, or your kid's bicycle. Springs counterbalance that weight so the opener can lift the door smoothly without burning out. See our guide on garage door repair in mission viejo: common problems, honest fixes, and when to call a pro.
Torsion springs sit on a metal rod above the door. They twist as the door opens and closes, storing and releasing energy with each cycle. Extension springs hang vertically on each side of the opening and stretch as the door lowers. Both types wear out eventually because they cycle thousands of times per year.
Most homes in Mission Viejo and nearby Laguna Hills use torsion springs because they last longer, operate more smoothly, and are safer when they fail. Extension springs are cheaper upfront but wear out faster and can whip dangerously if they snap.

Why Springs Fail (and It's Not Always Age)
Springs are rated for a specific number of cycles. A typical residential torsion spring lasts 7 to 9 years with normal use, which equals roughly 10,000 to 15,000 open/close cycles. But several factors speed up failure.
Rust eats springs from the inside out, especially in coastal Orange County climates where salt air corrodes metal. Poor lubrication increases friction and metal fatigue. Hitting the door hard, slamming it repeatedly, or even a sudden temperature swing can trigger a snapped spring without warning.
If your door suddenly feels heavier, moves unevenly, or won't open at all, your spring is likely compromised. Never try to force it open with the opener. That's how you bend the tracks, damage the opener, or worse. If you're stuck, check out our guide on garage door problems and honest fixes here.
Torsion vs. Extension Springs: What You Need to Know
Torsion springs are mounted horizontally above the door on a shaft. They handle the weight more evenly and fail less suddenly. When a torsion spring goes, the door becomes immovable but usually doesn't crash.
Extension springs run along the sides of the opening. They're simpler to install and cost less, but when one snaps, the other side still supports the door, creating dangerous imbalance and uneven lifting. Safety cables run through them to catch a snapped spring, but they can still whip with force.
For most Mission Viejo homeowners, torsion is the smarter choice. They're more reliable, quieter, and safer long term. The upfront cost difference isn't huge once you factor in lifespan.

Spring Replacement Cost in Mission Viejo
A single torsion spring replacement runs between $200 and $400 in labor and parts. Extension springs cost $150 to $250 per spring. If both springs need replacing (which we recommend), expect $400 to $700 total.
The cost depends on spring size, your door weight, local labor rates, and whether you need emergency same-day service. Prices vary across Orange County, but Mission Viejo rates are fairly consistent with Irvine and Newport Beach.
Never cheap out on springs. A $50 knockoff spring from an online marketplace might fail in two years. A quality spring from a licensed technician comes with a warranty and the peace of mind that it was sized correctly for your door.

When to Replace vs. When to Repair
If one spring is broken, we almost always recommend replacing both. Springs age together. If one failed, the other is under extra stress and will likely snap soon after. Replacing both at once saves you a second service call and keeps your door balanced.
In rare cases, we can repair a spring that's damaged but not snapped, but replacement is the safer, longer-lasting option. We'll never push you toward a bigger job than you need, but we'll always give you the honest assessment.
If your door isn't opening smoothly or won't stay up, springs might be part of the problem. But other components like the opener, tracks, or safety features also play a role. Read about five common safety mistakes homeowners make daily to rule out other issues.
Preventive Spring Maintenance
Springs don't need much, but a little care extends their life. Lubricate the spring and hinges twice a year with a silicone-based garage door lubricant. Avoid WD-40; it attracts dust and dries out quickly.
Keep the door balanced by opening it halfway with the opener and releasing the opener button. If the door drifts up or down, the springs need adjustment or replacement. An unbalanced door strains the opener and wears springs faster.

Frequently Asked Questions
How do I know if my garage door spring is broken? A snapped spring means your door won't open or feels extremely heavy when you try to lift it manually. You might hear a loud bang when it snaps. The door may hang unevenly or tilt to one side. Never force the opener if you suspect a broken spring.
Can I replace a garage door spring myself? Springs are under extreme tension and can cause serious injury or death if mishandled. We recommend professional replacement only. A technician has the right tools, knowledge, and insurance to do it safely.
How much does a garage door spring replacement cost? Single torsion spring replacement typically runs $200 to $400. Replacing both springs costs $400 to $700 depending on your door size and local rates. Emergency or same-day service may add a service fee.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use, rated for 10,000 to 15,000 cycles. Extension springs last 4 to 7 years. Lifespan varies based on usage frequency, lubrication, climate, and door weight.
Why do both springs need replacing at once? Springs age together under the same stress. If one fails, the other is near the end of its life too. Replacing both prevents a second costly service call in a few months and keeps your door balanced and safe.
