Garage Door Springs in San Ramon: Torsion vs. Extension (And Why It Matters)
7 min read A2Z Garage Doors
Here's what most homeowners don't realize about garage door springs: not all springs are created equal. Your garage door uses one of two types, and they behave very differently when they fail. The choice between torsion and extension springs affects your repair cost, how long they last, and whether you face an emergency call at 6 a.m. Understanding which system you have right now could save you hundreds of dollars down the road.
Torsion Springs: The Premium Choice
Torsion springs sit horizontally above your garage door opening, wound tight like a clock spring. When you open the door, they twist and release energy, making the lift feel smooth and controlled. Most newer homes in San Ramon use torsion systems because they're safer and more durable.
Torsion springs typically last 7 to 9 years with normal use. That's roughly 10,000 to 15,000 open-close cycles. When one snaps, the door becomes nearly impossible to open manually. You'll feel the full 300+ pound weight of the door pressing down. One key advantage: a snapped torsion spring usually fails gradually, giving you warning signs like jerky movement or visible gaps in the coil.
The trade-off is cost. Torsion springs run $150 to $300 per spring, plus labor. If both springs need replacement (and often they do, since they wear together), expect a higher bill.
Extension Springs: The Budget Alternative
Extension springs run along both sides of your door frame, stretching and contracting like accordions. Older homes and budget installations favor this design because springs cost less upfront, typically $75 to $150 each.
Here's the catch: extension springs fail fast and dangerously. When one snaps, it can whip across your garage with serious force. Safety cables run alongside extension springs to contain this snap, but nobody wants to test that system. Extension springs also wear unevenly, meaning one fails long before the other.

How to Tell Which Type You Have
Stand in your garage and look above the door. Do you see a horizontal metal shaft with wound coils running left to right? That's a torsion spring. See two springs running vertical along the sides? Those are extension springs.
Torsion systems are standard in most California homes built after 1990, including much of San Ramon. Older homes or rental properties sometimes still use extension springs.

What Happens When Springs Snap
A snapped spring doesn't just make your door stick. It shifts all load to your garage door opener, which wasn't designed to lift 300+ pounds solo. The opener motor strains, gears strip, and suddenly you're facing a $400 to $600 opener replacement on top of spring costs.
That's why 7 warning signs your garage door springs need replacement matter. Catching wear before failure saves money and prevents being trapped in your garage.
Some homeowners think they can patch or adjust a failing spring. Don't. Springs operate under extreme tension. A minor slip during DIY work can cause serious injury. This is genuinely one of those jobs worth leaving to trained technicians.
Cost and Timeline for Replacement
A single torsion spring replacement runs $250 to $400 installed, depending on spring quality and door weight. Both springs: $400 to $700. Extension springs cost less in materials but carry higher risk.
Most garage door shops in the San Ramon area, including ourselves, can handle same-day estimates and same-day installation if you call early. Waiting extends your risk of a complete opener failure.

Prevention Through Maintenance
Springs last longest when your door runs smoothly. Buildup, misalignment, and lack of lubrication force springs to work harder and fail sooner. Our garage door maintenance tune-up guide covers seasonal checks that catch problems early.
Real talk: you can't prevent spring failure entirely. Springs are wear items, like brake pads. But you can catch it before catastrophic failure, and that's worth the inspection cost.
Your garage door springs matter more than you think. Whether you have torsion or extension, whether they're brand new or showing age, treating them with respect keeps your family safe and your door working. If you're uncertain about your springs or noticed any warning signs, don't wait for a snapped coil to force your hand.

Frequently Asked Questions
How much does a garage door spring cost to replace? Torsion spring replacement ranges from $250 to $400 per spring installed, depending on door weight and spring quality. Extension springs cost less but fail faster. Most homeowners need both springs replaced together to avoid uneven wear.
Can I replace a garage door spring myself? No. Springs operate under extreme tension that can cause serious injury or death if mishandled. This requires specialized tools and training. Always hire a licensed technician for spring replacement.
How long do garage door springs last? Torsion springs typically last 7 to 9 years or 10,000 to 15,000 cycles. Extension springs often fail sooner, sometimes within 5 years. Frequency of use and maintenance affect lifespan.
What's the difference between torsion and extension springs? Torsion springs sit horizontally above the door and twist to lift. Extension springs run vertically on both sides and stretch. Torsion is safer, lasts longer, and costs more. Extension is cheaper but wears faster and fails dangerously.
Do I need to replace both springs at once? Yes. Springs wear together, and replacing one while the other is failing creates uneven stress. Your door opener strains, and you'll face another repair soon. Replace both to balance load and avoid future callbacks.
