A customer called last Tuesday saying her garage door wouldn't budge. She'd heard a loud snap the night before. We arrived, inspected the torsion spring, and found a clean break near the anchor point. Here's the honest answer: sometimes you repair just that one spring, sometimes you replace both. The choice depends on age, condition, and your budget.
Not every snapped spring means buying new ones. If your door is less than five years old and only one torsion spring failed, a repair often saves you $200 to $400 compared to replacing the pair. Springs last 7 to 9 years under normal use, so an early failure can signal a manufacturing defect, not wear and tear. See our guide on smart garage door technology remote access in san francisco: what actually works.
We've found that single repairs work best when:
- The other spring shows no signs of rust or pitting, Your door operates smoothly otherwise, You're willing to accept that the second spring will fail eventually (usually within 12 to 18 months). Read about emergency garage door service in san francisco: when to call and what it costs.
The trade-off is real, though. You'll pay for a service call twice, and the labor adds up. For homeowners on tight budgets, a repair buys time. For those wanting peace of mind, replacement of both springs upfront makes more sense.
Our Bay Area fog and salt air corrode metal faster than inland areas. If your garage faces the street or sits near the coast, corrosion weakens springs sooner. A spring that would last nine years in dry Nevada might fail in seven here. When we inspect springs in San Francisco, we look for rust spots and pitting. Those signs point toward replacement, even if the spring hasn't snapped yet.
Replacing both torsion springs at once costs more upfront, typically $400 to $600 for parts and labor. But you get years of uninterrupted operation and avoid the "one fails, the other follows" cycle.
Full replacement makes sense if:
- Your springs are over eight years old, Both show visible rust or corrosion, You want a single warranty period covering both, You've already had one spring fail before
When we do a replacement, we set both springs to the same tension and test the door balance thoroughly. That symmetry keeps your opener running smoothly and extends its life. An imbalanced door (one old, one new spring) works the opener harder.

A snapped spring means your door won't open or close smoothly. The weight transfers entirely to your opener, which can burn out in days. You're also at risk of the door slamming down unexpectedly, a genuine safety hazard. If you've got kids or pets, don't delay.

How do I know if my garage door spring is broken? Your door won't open, closes too fast, or you heard a loud snap. The door feels heavy to lift by hand. Do not force it; a broken spring means the full weight is on the cable and opener. Call for service immediately.
Can I replace a garage door spring myself? Springs are under extreme tension and can cause serious injury or death if mishandled. Even experienced DIYers should hire a professional. The cost of a service call is worth your safety and the correct installation.
How long does a garage door spring last? Typically 7 to 9 years with normal use (about 10,000 cycles). In San Francisco's salty, foggy climate, corrosion can shorten that to 6 to 8 years. Regular inspection catches problems before they strand you.
What's the difference between torsion and extension springs? Torsion springs wind around a shaft above the door and are more durable and safer. Extension springs run along the sides and are older technology. Most modern doors use torsion. We recommend upgrading if your door still has extensions.
Should I replace one spring or both? If one is under eight years old and uncorroded, repair is cheaper now. If both are aging, replace both at once to avoid a second failure soon. We'll assess during a free estimate and explain the cost difference clearly.
