A customer called last Tuesday with a door that wouldn't budge. One look told me: snapped torsion spring. That's the most common emergency we handle in San Francisco, and it's also the most misunderstood. Garage door springs in San Francisco don't fail at convenient times, but understanding their cost, lifespan, and replacement timeline helps you avoid being stranded.
Your garage door weighs 300 to 500 pounds. Two springs counterbalance that weight so your opener doesn't labor itself to death. Most residential doors use torsion springs, which twist and unwind as the door moves up and down. Extension springs, less common in the Bay Area, work differently but serve the same purpose. See our guide on emergency garage door service in san francisco: when to call and what it costs.
Springs last roughly 7 to 9 years with normal use. They're rated for about 10,000 cycles. A cycle is one open and one close. If you open your door three times daily, you're looking at about 1,100 cycles per year. Do the math: a spring rated for 10,000 cycles gives you roughly nine years before fatigue sets in.
When a spring snaps, you hear it. A loud bang or crack. The door either hangs awkwardly or won't open at all. Don't force it. A broken spring means the opener is now handling full door weight, and that's how you burn out a $400 opener trying to save on a $200 spring replacement. Read about 5 warning signs your garage door needs professional repair.
Transparency matters to us. A torsion spring replacement runs between $200 and $400 per spring, including labor and a new cable if needed. If both springs are original, they're roughly the same age. Replacing only one often leads to the second failing within months. We usually recommend replacing both at once.
Extension springs are slightly cheaper to replace, typically $150 to $300 per spring. But torsion is the industry standard for reliable, quiet operation, especially in San Francisco's older neighborhoods where smooth, predictable door movement matters.
Labor time varies. A straightforward torsion replacement takes about an hour. If your cables are worn or your door frame is out of square, add another 30 minutes. Same-day service costs the same as scheduled appointments with us. We don't charge extra for urgency.

Not every spring problem requires replacement. Minor issues like rust, squeaking, or slight tension loss sometimes warrant repair. But once a spring snaps, replacement is your only option. Welding a torsion spring is unsafe. Spliced springs fail suddenly and unpredictably.
If your springs are original to a 15-year-old door, replacement is the smart move even if one hasn't failed yet. Preventive replacement costs less than an emergency call at midnight plus the risk of your door crashing down mid-operation. Check our garage door safety features guide to understand why spring failure ties directly to safety hazards.

Torsion springs are under extreme tension. Improperly installed springs cause serious injury. We've seen homeowners attempt DIY replacement and end up with torn fingers or worse. The tools are specialized. The adjustment requires precision calibration. A spring wound too tight or too loose wears out prematurely or fails catastrophically.
Professional replacement includes safety testing, proper tension adjustment, and a warranty on parts and labor. Learn what safety testing actually covers to understand why this matters beyond just convenience.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years under normal use, rated for approximately 10,000 cycles. Frequency of use and climate conditions in San Francisco can slightly extend or reduce lifespan.
Can I open my garage door if a spring is broken? No. A snapped spring removes counterbalance, forcing the opener to lift full door weight. This risks opener burnout and potential door collapse. Call for professional service immediately.
What's the difference between torsion and extension springs? Torsion springs twist above the door. Extension springs stretch alongside the tracks. Torsion is more reliable and quieter, preferred for residential doors in San Francisco and across the Bay Area.
How much does spring replacement cost near me? Professional torsion spring replacement costs $200 to $400 per spring including labor. Extension springs run $150 to $300. Many homeowners replace both springs simultaneously to avoid a second failure within months.
Is spring replacement covered by warranty? We warranty parts and labor on all spring replacements. If a spring fails prematurely due to defect, we replace it free. Always ask about warranty details when you call for your estimate.
