Your garage door springs are the hardest-working part of your entire system, yet most homeowners never think about them until one snaps. A broken spring doesn't just make your door inoperable; it creates a serious safety hazard. In San Francisco, garage door spring replacement typically costs between $150 and $400 per spring, depending on type, quality, and labor. Understanding what drives that cost can save you money and keep your family safe.
Garage door springs operate under extreme tension. A typical residential door weighs 300 to 400 pounds. Those springs counterbalance that weight every single time you open or close the door. Over 7 to 9 years of normal use, the metal fatigues and eventually snaps.
There are two main types: torsion springs (wound around a rod above the door) and extension springs (running along the sides). Torsion springs are more durable and safer, but they cost more to replace. Extension springs are cheaper but wear out faster and pose a higher risk if a cable breaks.
San Francisco's fog and salt air accelerate rust and corrosion. Springs that might last nine years elsewhere can fail in seven here. I've seen springs snap while families were in their cars. That's not rare; that's why I'm writing this.
Several factors determine your final bill:
Spring type. Torsion springs run $200 to $400 installed. Extension springs cost $150 to $250. Torsion is the safer, longer-lasting choice and worth the premium.
Spring quality and gauge. Heavier-gauge springs (thicker wire) cost more but last longer. Budget springs fail sooner and mean repeat calls.
Labor. Professional installation takes 1 to 2 hours. Same-day service in San Francisco typically adds a small rush fee, but it's worth it when you're stuck without a working door.
Both springs or one. If one spring snaps, the other is usually close behind. Many professionals recommend replacing both at once to avoid a second failure weeks later. That doubles the parts cost but saves labor and hassle.
When you request an estimate, be clear about whether you want both springs replaced. A reputable company will recommend it; a cheap shop might not.

Don't wait for a snap. Watch for these warning signs:
The door feels heavier when opening manually. Springs are losing tension. A loud bang or crack from the garage means a spring just broke. The door opens only partway or closes unevenly. The opener strains or shuts off mid-cycle.
If you notice any of these, stop using the door and call a professional. Forcing a broken spring system can damage the opener and create injury risk. We've written a full guide on 5 warning signs your garage door springs need replacement that covers the details.
I'll be direct: don't attempt this yourself. Spring replacement involves pressurized steel cables and hundreds of pounds of tension. A slip costs fingers, hands, or worse. I've seen injuries that could have been prevented with a $250 professional call.
A licensed technician has the right tools, knows how to safely release tension, and guarantees the work. The cost difference between a DIY attempt gone wrong and professional installation is not small. Your homeowner's insurance likely won't cover DIY injuries either.
This is one of the few garage door repairs where professional service is non-negotiable.

You can't prevent springs from aging, but you can slow it. Lubricate the springs every six months with a light machine oil. Keep the garage dry to reduce rust. Address door misalignment quickly because it puts extra strain on springs.

How long do garage door springs last? Most torsion springs last 7 to 9 years with normal use. In San Francisco's humid, salty climate, expect closer to 7 years. Extension springs wear out faster, typically 5 to 7 years. Frequency of use and maintenance affect lifespan significantly.
Can I replace just one spring? Technically yes, but it's not wise. If one spring has reached its lifespan, the other is close. Replacing both at once prevents a second failure in weeks and saves labor costs. Most professionals recommend replacing both for safety and value.
Is spring replacement covered by homeowner's insurance? Typically no. Spring failure is considered normal wear and tear, not a covered event. Some extended service plans or warranty programs may cover it. Check your policy or ask your technician about service plans.
How much does emergency spring replacement cost? Same-day or after-hours service usually adds $50 to $100 to the standard repair cost. In San Francisco, that's often worth it to restore access quickly. Call for current pricing on your specific situation.
What's the difference between torsion and extension springs? Torsion springs are safer, last longer, and cost more. Extension springs are cheaper but fail sooner and have higher injury risk if the cable breaks. For safety and durability, torsion is the better choice.
