In our years serving San Francisco, we've seen this problem again and again: a homeowner wakes up, clicks the opener, and nothing happens. The garage door won't budge. Nine times out of ten, it's a snapped garage door spring. The good news? You can handle this affordably if you know what to expect. This guide walks you through the problem, the real cost, and when calling for same-day service actually saves you money.
Torsion springs and extension springs both wear out over time. Most springs last 7 to 9 years under normal use, depending on cycles (open/close). A spring that opens and closes 3 to 5 times daily will fail sooner than one used twice weekly. Salt air and fog in the Bay Area accelerate corrosion, especially for older homes near the coast.
The snap itself usually happens quietly. You'll notice it when the door feels heavier than normal or won't open at all. Sometimes you'll hear a loud bang, but not always. Don't panic and don't force the opener. A broken spring means the door's full weight (300 to 400 pounds) is no longer balanced. Pushing it stresses the opener motor and can cause additional damage.
Torsion springs sit on a shaft under extreme tension. If you've never worked on one, the physics alone can cause serious injury. The spring is under thousands of pounds of force, and releasing that tension incorrectly has sent people to the emergency room. Extension springs are slightly less hazardous but still dangerous if the cables snap while you're working.
The cost difference between a DIY attempt and a professional repair is usually $100 to $150. Call a trained technician instead. We've patched up more than a few DIY disasters in San Francisco, and the emergency visit always costs more than the original job.

If only one spring is snapped, you'll likely replace both. Springs wear as a pair, and if one has failed, the other is close behind. Replacing one spring now and the second one in three months doubles your service calls and labor costs. A replacement job usually runs $250 to $500 total for both springs, depending on spring type and door size.
Before any work starts, ask for a written estimate that includes labor, parts, and tax. Reputable shops will inspect both springs under load and let you know if both need replacement or just one. If a technician tells you to replace springs that aren't broken yet, get a second opinion.
Check our post on garage door springs repair versus replacement decisions for deeper cost breakdowns and when replacement actually makes financial sense.
Extension springs run horizontally along the sides of the door frame. Torsion springs sit above the door on a horizontal shaft. Torsion springs are more expensive to replace (usually $300 to $500 combined labor and parts) but last longer and operate more smoothly. Extension springs cost less upfront ($150 to $300) but may need replacement sooner.
Your current spring type determines the repair cost. If you're not sure which you have, the technician will identify it during the inspection. Don't worry about guessing. Just mention what you've noticed, and we'll take it from there.
San Francisco has enough garage door companies that you shouldn't pay a premium simply because it's 6 p.m. on a Tuesday. Same-day service is standard for us, not an upsell. Emergency charges (nights, weekends, holidays) typically add 30% to 50% on top of the base repair cost. If your door can wait until morning or the next business day, scheduling then will save you $75 to $150.
If your garage door opener depends on that door (blocked driveway, parked car inside), urgent service makes sense. Otherwise, book a same-day appointment during regular hours and pocket the savings.
Springs fail fastest when doors aren't maintained. Regular lubrication, cable checks, and safety inspections catch wear early. A professional tune-up costs around $150 to $200 and can add a year or two to your spring's life. See our garage door maintenance guide for seasonal care tips.
If your springs are over 8 years old, start planning for replacement now. You'll avoid the shock of an unexpected failure and can budget for the work without rushing into a more expensive emergency repair.
Don't use your garage door until the spring is fixed. You risk motor damage and personal injury. Contact us for a free estimate. We'll schedule a time that works for you, provide a firm cost quote, and handle the repair safely. Most jobs finish in one to two hours.

How long do garage door springs typically last? Most springs are rated for 10,000 cycles, which translates to 7 to 9 years of typical residential use (3 to 5 cycles daily). Heavy use or coastal salt exposure can shorten lifespan to 5 to 6 years. Professional inspection every 2 to 3 years catches wear early.
Can a snapped spring damage my garage door opener? Yes. The opener isn't designed to lift the full door weight without spring assistance. Attempting to open a door with a broken spring forces the motor to work beyond its capacity, potentially burning out the mechanism and requiring a $300 to $600 replacement.
What's the difference between extension and torsion spring costs? Torsion springs cost 20% to 40% more upfront but last longer and provide smoother operation. Extension springs are cheaper initially but may need replacement sooner. Long term, torsion is usually the better investment for most San Francisco homes.
Should I replace springs during regular maintenance or only when they fail? If springs are 8+ years old and showing wear (visible rust, uneven door movement), replace them proactively. You'll avoid sudden failures and the higher costs of emergency calls. A replacement during scheduled maintenance costs less than an emergency repair.
