A customer called last Tuesday asking why his garage door spring repair quote from another shop was nearly double what he expected. Turns out he didn't understand the difference between torsion and extension springs, or why labor costs swing so wildly depending on your door's age and setup. That conversation is exactly why I'm writing this: garage door springs in Sunnyvale typically run $150 to $400 per spring, but the final cost depends on several factors most homeowners never consider.
Spring replacement isn't just about the part itself. When you get an estimate, you're paying for the spring, the labor to safely remove and install it, and the technician's experience to diagnose what caused the failure in the first place.
A single torsion spring costs between $100 and $250, depending on your door's weight and size. Extension springs run $75 to $150 each, but most doors have two of them. Labor adds another $150 to $300, sometimes more if your door has complications or if we're doing same-day service on a weekend.
The reason prices vary so much comes down to your specific setup. A lighter single-car door with a standard extension spring takes 45 minutes. A heavy two-car door with a center-mounted torsion spring and rust buildup can take two hours. That's the difference between a $200 job and a $500 job, and both are fair.
Torsion springs sit above your door on a horizontal rod and twist to lift the weight. They're more durable, last longer, and handle heavier doors better. They also cost more to replace because installation requires precision and special tools.
Extension springs run along the sides of your door and stretch to provide lift. They're cheaper upfront but wear out faster and pose a safety risk if they snap. If you've got extension springs and one snapped, the other likely won't be far behind. We often recommend replacing both at once to avoid a second service call in six months.

Age matters more than most people realize. If your door is 15 years old with original springs, there's often rust, corrosion, or cable damage we discover once we start work. A quick 30-minute job becomes an hour when we have to clean, adjust cables, or lubricate tracks.
Your opener's condition also affects price. A worn opener puts extra strain on springs, which means they fail sooner and wear unevenly. If we spot that during inspection, we might recommend a tune-up or opener service alongside the spring replacement.
Location within Sunnyvale and surrounding areas like Cupertino can affect scheduling and pricing too. Our service area covers all of Silicon Valley, but same-day appointments sometimes carry a small premium during peak seasons.
I always tell customers: don't just compare numbers between quotes. Ask what's included. Does the estimate cover cable inspection? Spring lubrication? A safety check on the opener? The cheapest quote often misses these details, which means you'll call back in three months with a new problem.
The best way to understand cost is to schedule a free inspection. We'll look at your springs, check for damage, and give you a firm price before we touch anything. Most estimates take 15 minutes, and you'll know exactly what's broken and what it costs to fix.

Preventive maintenance also saves money over time. A snapped spring is an emergency. A spring that's showing wear can be replaced during a routine maintenance visit at your convenience. If you're not sure when your door last got attention, we offer comprehensive maintenance that catches problems before they become expensive repairs.
Don't try to replace springs yourself. I've been doing this 15 years, and I still respect the tension these springs hold. A snapped spring can cause serious injury. Call a professional. It's faster, safer, and honestly not much more expensive than the tools you'd buy to do it wrong.
If your door is stuck, making noise, or moving unevenly, springs are often the culprit. Schedule a free quote today by calling 669-356-8618 or filling out our contact form. We'll give you a real number, not a range.

How much does it cost to replace one garage door spring? A single spring replacement runs $200 to $400 total, including labor. Torsion springs cost more than extension springs. The final price depends on your door's weight, spring type, and whether rust or damage slows the job.
Should I replace both springs at once? Yes. If one spring fails, the other is under the same wear and stress. Replacing both together prevents a second emergency call within months and ensures balanced, even operation.
Why do some quotes seem so cheap? Low quotes often exclude inspection, lubrication, cable checks, or safety testing. Ask exactly what's covered before booking. The cheapest option isn't always the best value.
Can I replace a garage door spring myself? No. Springs hold hundreds of pounds of tension and can cause serious injury if mishandled. Professional installation is safer and usually warrants the work.
How often do garage door springs fail? Quality torsion springs last 7 to 9 years with normal use. Extension springs wear faster, typically 5 to 7 years. Hard use, poor maintenance, or extreme temperature swings shorten lifespan.
