A customer called last Tuesday with a snapped torsion spring. Her door was stuck halfway up. She'd already gotten two quotes: one at $800, another at $1,200. Both felt wrong. Here's what actually happens with garage door torsion springs in San Jose, and how much a fair replacement really costs.
Your garage door weighs 300 to 500 pounds. It doesn't fall on your head because torsion springs counterbalance that load. These metal coils sit above the door on a shaft, twisting under tension to lift and lower the panel smoothly.
Torsion springs last 7 to 9 years with average use (opening and closing 3 to 5 times daily). They fail because metal fatigues. Every cycle stretches and compresses the coil. Eventually, a weak spot gives out. You hear a loud bang. The door drops. That's a snapped spring.
Unlike extension springs (which run along the sides and are less common in modern San Jose homes), torsion springs carry all the load. One failure means the whole door becomes unmanageable. This is why you can't ignore a snapped spring, and why prices vary so much.
Two springs or one? That's the first question. Many doors have two torsion springs working together. If one fails, both are likely near the end of their life. Replacing just one leaves you vulnerable to a second failure in weeks or months. Smart homeowners replace both at once. That costs more upfront but saves a second service call.
Your door's weight matters too. Standard residential doors (8 feet wide) use lighter springs than oversized doors (9 to 10 feet) or custom panels. Heavier doors need stiffer springs rated for higher cycles. A custom commercial application costs differently than a standard residential replacement.
Labor time varies by technician and location. In San Jose, a straightforward torsion spring replacement takes 45 minutes to 90 minutes per spring. If your door has rust, a stuck shaft, or damaged hardware, the job takes longer.

A single torsion spring replacement in San Jose typically runs $250 to $400, including labor and the spring. Both springs together cost $450 to $700. Emergency calls (evenings, weekends, holidays) add $100 to $150 more.
Here's what builds a realistic estimate. Quality matters. A cheap spring ($40) versus a durable one ($80) changes longevity. Better springs last those full 9 years. Cheap ones may fail again in 3 to 4 years. Over time, one quality job beats two cheap jobs.
Call Garage Door San Jose for a free estimate. We'll inspect both springs, the shaft, and mounting hardware. If only one spring is weak, we'll tell you. If both need replacement, we'll explain why. No pressure, no hidden fees. You'll know the cost before we start work.
For a detailed breakdown of what honest repair costs look like, check our guide on garage door springs in San Jose: why they fail and what repair costs.
You can't repair a snapped torsion spring. Welding isn't safe. The spring won't hold tension evenly. Replacement is the only option.
If your door is over 15 years old and the springs fail, ask yourself: is the whole door worth keeping? Sometimes a new installation costs less than repeated repairs. We can help you compare options without pressure. Check our pricing guide for new installations in San Jose to see where replacement makes sense.
Also, don't ignore safety warnings. A snapped spring means the door can fall suddenly. Keep people and pets away. Call a professional immediately.
Get two or three quotes. Ask each technician: are you replacing one or both springs? Why? What's included in the price? Do you guarantee the work?
Ask about the spring brand and cycle rating. A spring rated for 25,000 cycles lasts longer than one rated for 10,000. The difference in cost is small but the longevity difference is huge.
Don't let a technician talk you into a full door replacement if springs are your only issue. A snapped spring is common and fixable. It's not a sign your door is failing.
Most importantly, call early. A snapped spring isn't an emergency if you're not planning to leave soon. But waiting weeks invites rust, damage to the shaft, or worse. Schedule a free quote today and get a clear answer about what you need and what it costs.
Quality torsion springs last 7 to 9 years with normal residential use (3 to 5 cycles daily). Heavier doors or frequent use may shorten this. Springs are rated by cycle count, typically 10,000 to 25,000 cycles. One cycle equals one up and one down.
Technically yes, but it's risky. If one spring failed, the other is likely near the end of its life too. Replacing both costs more upfront but prevents a second failure in weeks. Most professionals recommend replacing both for safety and value.
A single spring runs $250 to $400. Both springs together cost $450 to $700 including labor. Emergency service (nights, weekends) adds $100 to $150. Prices vary based on spring quality, door weight, and your exact location within San Jose.
Torsion springs twist above the door and carry all the load. Extension springs run along the sides and pull to lift the door. Torsion springs are standard in modern homes and safer because they're enclosed. Extension springs are older, less common in San Jose, and more prone to injury if they snap.
Listen for creaking or grinding sounds when opening or closing. Watch for the door moving unevenly or one side sagging slightly. If the door feels heavier than usual, springs are weakening. These are warning signs to call a technician before a complete failure happens.
