Garage Door Springs in San Francisco: Repair vs. Replacement

2026-06-26 7 min read

Your garage door springs are the hardest working parts of your entire system. When one fails, your door becomes a 300-pound dead weight. The question isn't whether you need springs fixed; it's whether repair makes sense or if replacement is the smarter move. Both torsion and extension springs fail predictably, and knowing the difference saves money and headaches.

Why Springs Fail (And It's Not Random)

Garage door springs last roughly 7 to 9 years under normal use. That's about 10,000 to 15,000 cycles. In San Francisco's coastal climate, salt air and fog accelerate rust and metal fatigue faster than inland homes experience. A snapped spring typically signals the end of that component's life, not a temporary glitch. See our guide on garage door insulation in san francisco: what r-value actually means.

Two types handle most residential doors. Torsion springs sit above the door and twist to lift weight. Extension springs run along the sides and stretch. Torsion springs are more durable and safer when they fail (they stay contained). Extension springs can whip dangerously when they snap. Both types endure constant tension. Metal simply fatigues over time.

Repair vs. Replacement: The Real Costs

Here's what matters: a single spring replacement costs between $200 and $400 for parts and labor. A snapped spring on a two-spring door means you're likely looking at replacing both, since the surviving spring has already done double duty and won't last long alone. That pushes cost to $400 to $800 total.

Repair attempts rarely work. Springs don't gradually weaken and then recover. Once cracked or snapped, they're done. Some homeowners attempt a temporary fix with cable or a makeshift support. This creates a safety hazard. An unbalanced door strains the opener, can slip off tracks, and puts pressure on hardware that wasn't designed for asymmetric load.

Our team at Garage Door San Francisco recommends replacing both springs if one fails, even if the second looks fine. You'll avoid a second service call in weeks and restore proper balance to your door right away. Schedule a free quote to get an accurate estimate for your specific door model.

Torsion vs. Extension: Which Do You Have?

Torsion springs mount horizontally above the door on a metal rod. They're the preferred design because they're safer and more stable. If your door is newer or a quality installation, you likely have torsion springs.

Extension springs hang vertically on each side of the door track. Older homes and budget installations often use these. They're cheaper upfront but less durable and more prone to dramatic failure. Safety cables run alongside them to catch a snapped spring, but that's a band-aid solution.

Check your door from inside the garage. Look above the door opening. See a horizontal rod with coiled metal? That's torsion. See springs running up and down the track sides? That's extension. When you explore garage door maintenance, you'll recognize these components and spot early wear signs.

Why DIY Spring Work Is Dangerous

Springs are under extreme tension. A torsion spring rod can spin violently when you loosen it. An extension spring can snap and strike your face or hands with enough force to cause serious injury. We've treated customers who attempted this themselves. It's not worth the risk.

Professional technicians use proper winding tools, safety bars, and experience gained over hundreds of replacements. A same-day spring replacement takes 45 minutes to an hour when done correctly. Trying it yourself can take hours and end badly.

When to Call for Emergency Service

A snapped spring isn't always an emergency, but it's urgent. Your door won't open smoothly, if at all. Some doors with one failed spring can still operate, but the remaining spring and opener work overtime. You're looking at secondary damage within days.

If your door won't open or closes too fast, stop using it. Get a technician out quickly. Learn more about emergency garage door service in San Francisco if you need same-day help.

What Your Estimate Should Include

A good estimate breaks down parts, labor, and any additional repairs. Springs themselves are $80 to $150 each depending on type and size. Labor is typically $150 to $250 per hour for a two-spring job. If tracks need adjustment or the cable is worn, that gets added.

Never accept a quote over the phone without inspection. Door size, spring type, and damage scope all affect cost. Our services page outlines what we include in every spring service.

Frequently Asked Questions

How long does a spring replacement take? A professional replacement typically takes 45 minutes to an hour per spring. If both springs need replacement, plan for about 90 minutes total. We can often fit same-day appointments for spring work.

Can I drive under a garage door with a broken spring? No. A snapped spring means the door isn't properly balanced and could fall unexpectedly. Don't operate the door. Call for service immediately to avoid injury or further damage.

Is it always both springs, or can I replace just one? If one snaps, the other is usually near the end of its life. Replacing both ensures balance and prevents a second failure within weeks. Most professionals recommend replacing both for safety and cost efficiency.

What's the difference between repair and replacement? Springs cannot be repaired once cracked or snapped. Replacement is the only solution. A "repair" claim usually means temporary rigging, which is unsafe and short-lived.

Do homeowner's insurance cover spring replacement? Most homeowner's policies don't cover wear-and-tear failures. Spring replacement is typically a homeowner's cost. Some warranties apply if your door is under one year old; check your paperwork.
