Garage Door Springs in South San Francisco: Cost, Repair, and When to Replace

2026-05-20 A2Z Garage Doors

Last Tuesday, a customer called in a panic. Her garage door wouldn't budge, and she'd heard a loud snap from the garage that morning. Within an hour, our crew confirmed what she suspected: a snapped torsion spring. Garage door springs in South San Francisco fail more often than most homeowners realize, and knowing what to expect can save you stress, money, and lost time.

Why Springs Fail (And When Yours Might)

Garage door springs carry enormous tension. A typical residential door weighs 300 to 400 pounds, and springs counterbalance that load every single time you open or close. Over years of cycling, metal fatigues. Springs last roughly 7 to 9 years under normal use, though Bay Area fog and salt air accelerate rust and wear.

Two main types handle this job: torsion springs sit above your door and twist as it opens, while extension springs run along the sides and stretch. Torsion springs are more common in newer homes and handle the load more smoothly. When one fails, the door becomes deadweight. You can't open it safely, and forcing the opener can damage the motor.

The cost varies by type and your local market. A torsion spring replacement typically runs $200 to $400 in South San Francisco, while extension springs run $150 to $300. Labor adds another $150 to $250 if you hire a professional. If both springs need replacing at the same time, expect to budget closer to $400 to $600 total. Sounds steep, but a broken spring left unrepaired invites secondary damage to your opener and door panels.

Signs Your Springs Are About to Give

Before a spring snaps, there are warnings. If your door moves slowly, hesitates, or feels heavier than usual, the springs are weakening. A loud bang from the garage is the classic red flag. Some doors drift downward even when closed, meaning springs can't hold the weight anymore. We documented this in our post on 5 warning signs your garage door spring needs replacement, which covers the full checklist.

Never try to force a broken spring door open by hand or with the opener. You risk serious injury. The door itself can fall, and the opener motor will burn out trying to lift deadweight.

Repair Versus Replacement

Sometimes one spring fails and the other is fine. If your door is relatively new and the failed spring is less than 5 years old, replacing just that one might make sense. However, springs age together. If one has failed, the other is under stress and likely to fail within months. Most technicians recommend replacing both at once to balance the load and avoid a second service call.

Getting a Same-Day Estimate

When you call Garage Door South San Francisco about a snapped spring or suspected failure, we ask a few quick questions: What type of door do you have? When did it fail? Does the door move at all? From there, we can often quote a repair cost and schedule you for same-day service if the job is straightforward.

Avoid the temptation to DIY spring replacement. These components operate under extreme pressure. A slip or miscalibration can cause the door to crash, damage your car, or injure you. Professional installers have the tools, knowledge, and liability coverage to get it right the first time.

Frequently Asked Questions

How long does a garage door spring replacement take? Most spring replacements take 1 to 2 hours, depending on whether one or both springs need work and the door type. We aim for same-day service in South San Francisco whenever possible.

Can I open my garage door if the spring is broken? No. Never force a broken spring door open by hand or opener. You risk serious injury and motor damage. Call for professional help instead.

What's the difference between torsion and extension springs? Torsion springs twist above the door and handle load more evenly; extension springs stretch along the sides. Torsion is more common in new homes and lasts longer under normal use.
