Garage door springs in San Francisco fail without warning, and confusion about types, costs, and lifespans costs homeowners real money. Torsion springs last 7 to 9 years under normal use, while extension springs wear faster. Replacement typically runs $200 to $400 per spring, but DIY attempts can damage your opener or door, turning a $300 fix into a $2,000 nightmare. This post cuts through the confusion so you spend smart.
Your garage door uses one of two spring systems: torsion or extension. Each behaves differently, fails differently, and costs differently to replace.
Torsion springs sit horizontally above your door, wound tight like a clock. They do the heavy lifting when your door opens and closes. These are the industry standard in San Francisco homes built after 1990. A snapped torsion spring means your door becomes nearly impossible to open manually because you've lost the counterbalance mechanism.
Extension springs run along the sides of your door frame, stretching and contracting like rubber bands. They're cheaper upfront but wear out faster, typically within 5 to 7 years. If an extension spring snaps, your door may jerk or bind on one side.
The type you have determines your replacement cost and safety profile. If you're unsure, don't guess. A professional can identify your system in seconds and provide an accurate estimate. You can also learn more about signs your springs need replacement now to catch problems early.
Spring replacement costs depend on several real factors, not just the part itself.
Spring quality and brand matter. A heavy-duty residential torsion spring from a reputable manufacturer runs $150 to $250. Budget springs fail sooner and void warranties. Professional-grade springs cost more but last longer, saving money over time.
Labor and service model affect your final bill. Same-day service in San Francisco costs more than scheduling a week out. Emergency calls after hours carry premiums. A standard appointment with both springs replaced typically runs $350 to $500 total, including labor and hardware.
Door weight and system complexity play a role too. Heavier doors (fiberglass or insulated models) need stronger springs, which cost more. If your opener is old or misaligned, the technician may recommend additional adjustments, adding to your estimate.

Replacing garage door springs yourself is dangerous and expensive. Springs hold 200 to 400 pounds of tension. A slip or wrong technique can send a spring flying or drop your door, injuring you or damaging the opener.
Even if you avoid injury, mistakes pile up costs. Over-tightening a spring warps your door. Misaligning the cable system grinds your opener's gears. Installing mismatched springs creates uneven wear and premature failure. One bad DIY attempt often requires a pro to fix it plus replace parts, turning a $300 job into $1,200 or more.
For context, check our repair versus replacement guide to understand when replacement is your only safe option.
A well maintained torsion spring lasts 7 to 9 years in San Francisco's climate. Salt air near the coast speeds corrosion, shortening lifespan by a year or two. Extension springs typically last 5 to 7 years because they flex more and fatigue faster.
Maintenance doesn't extend spring life dramatically, but it catches problems early. Lubricate your springs and cables twice yearly with silicone spray. Listen for squeaks or creaks. If your door feels heavier or jerks, don't wait. A small issue becomes a snapped spring if ignored.
Our garage door maintenance guide covers seasonal checks that prevent emergency calls. Spend 30 minutes now to avoid a $500 repair later.

How do I know if my garage door spring is snapped? Your door won't open or feels extremely heavy when you try to lift it manually. You may hear a loud bang when the spring breaks. Never force a door with a broken spring; call a professional immediately to avoid injury or opener damage.
Can I replace just one spring if both are old? Technically yes, but it's poor practice. Old springs wear at similar rates. Replacing one leaves a weaker partner to fail soon after, creating imbalanced door movement. Most professionals recommend replacing both at once, spreading labor costs and preventing repeat service calls.
How much does emergency spring replacement cost in San Francisco? Same-day or after-hours service typically adds $75 to $150 to your standard quote. If you need it at 10 p.m. on a Saturday, expect to pay a premium. Standard business hours appointments keep costs closer to $350 to $500 for both springs plus labor.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely, making your door inoperable. A worn spring still functions but shows signs of failure like slower opening, jerking, or unusual noise. Worn springs need replacement soon but aren't immediate emergencies; snapped springs require urgent service.
Do I need to replace my garage door opener when I replace springs? Not always. If your opener is modern and works smoothly, new springs often solve the problem alone. However, if your opener is over 15 years old, a technician may recommend replacement since wear compounds with age. We'll advise you based on your specific system.
