Garage Door Springs in Burlingame: Torsion vs. Extension & Why It Matters
2026-07-27 7 min read
Garage door springs are the backbone of your door's operation. Torsion springs (wound above the door) and extension springs (running along the sides) both fail eventually, and when they do, your door becomes a 400-pound paperweight. I've seen too many Burlingame homeowners try to ignore the warning signs, only to face a much larger repair bill or worse, a safety incident that could have been prevented.
Understanding Torsion vs. Extension Springs
Most modern garage doors use torsion springs, especially in the Bay Area. These coiled springs sit on a metal rod above your door and use rotational force to lift the weight. They're engineered to handle the door's entire load and typically last 7 to 9 years with normal use.
Extension springs are the older design. They run horizontally along both sides of the door and stretch to provide lift. You'll find them on lighter doors or older installations. Extension springs usually fail faster than torsion springs because they work harder and experience more stress per cycle.
The key difference: torsion springs fail suddenly and completely. Extension springs often give you warning signs first (sagging door, uneven movement). Neither type is "better" in an absolute sense. Your door's design, weight, and usage determine which you have.
Why Springs Snap and What Causes Early Failure
A snapped spring doesn't happen by accident. Springs fail due to age, rust, metal fatigue, and the sheer repetition of opening and closing (up to 10,000 cycles per year). In Burlingame, coastal humidity accelerates rust formation on the spring coils, which weakens the metal from the inside out.
Poor maintenance is the silent killer. If you've never had your springs inspected or your door lubricated, you're accelerating the breakdown. Temperature swings also matter. The metal contracts and expands, creating microscopic fractures over time.
Here's what I've seen go wrong: a homeowner ignores a slight squeak for months, the spring weakens further, then one day it snaps while the door is opening. Now the door hangs crooked, the opener motor strains, and the entire system is at risk.

Spring Replacement Cost and Timeline
A torsion spring replacement typically costs between $150 and $300 per spring, depending on the spring's size and quality. Extension springs run slightly less, around $100 to $200 each. Most doors have two springs, so budget accordingly. If you need both springs replaced at the same time (which is often smart to avoid a second failure soon after), expect to pay $300 to $600 total for parts and labor.
The timeline for same-day service is realistic if you call before noon. Our team can usually diagnose and replace a snapped spring within 2 to 4 hours. If you wait until evening or weekend, you might face a longer wait, depending on call volume across Burlingame and nearby areas like San Mateo.

Warning Signs You Can't Ignore
Listen for a loud bang or crack from the garage. That's the sound of a spring giving out. You might also notice the door opening slowly, sagging on one side, or not closing all the way. If the door feels heavier than usual or the opener is struggling, springs are likely the culprit.
Don't try to manually open a door with a broken spring. You could injure yourself. The door's weight is no longer being supported, and the opener motor wasn't designed to lift it alone.
If you're curious about the bigger picture of garage door maintenance, learn how often you should service your door to catch problems like spring wear before they become emergencies. You can also review the warning signs specific to springs that many homeowners miss.
Choosing the Right Spring Replacement
When a spring fails, you have options. You can replace it with the same type and size (recommended to keep door balance), or you can upgrade to a higher-cycle spring that lasts longer. Commercial-grade springs rated for 15,000 to 20,000 cycles cost more upfront but often save money over the door's lifetime.
Garage Door Company Burlingame always recommends matching spring specifications exactly. Using the wrong spring can throw off your door's balance, strain the opener, and create new safety hazards.

Don't Wait on Spring Repairs
A broken spring isn't a "wait and see" situation. Every day your door sits inoperable, you're at higher risk of a security issue or a blocked garage. Humidity and salt air in Burlingame can also worsen rust on the exposed spring components if left exposed.

Frequently Asked Questions
How long do garage door springs really last? Torsion springs typically last 7 to 9 years under normal use (about 1,400 cycles per year). Extension springs may last 5 to 7 years. Coastal humidity in Burlingame can reduce these timelines by 1 to 2 years due to rust formation.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools, training, and extreme caution. A spring under tension can snap unexpectedly and cause serious injury or death. Always hire a licensed professional.
What's the difference between a snapped spring and a loose spring? A snapped spring means the metal has fractured completely and the spring is no longer functional. A loose spring is still intact but may have lost tension. Both require professional inspection and usually replacement.
How much does a spring replacement cost near me in Burlingame? Most single-spring replacements cost $150 to $300, while both springs typically run $300 to $600 including labor. Call 510-680-2703 for a same-day estimate based on your door's specifications.
Will my garage door opener work if the spring is broken? No. The opener will either refuse to open the door or struggle dramatically. Forcing it can burn out the motor. A broken spring means no door operation until it's repaired.
