Here's what most homeowners don't realize about garage door springs: they're under constant, extreme tension and will eventually snap without warning. I've been pulling trucks for 15 years around San Jose, and I can tell you that a snapped spring isn't just an inconvenience. It's a safety hazard that can leave your door stuck closed, damage your opener, or even injure someone. Understanding how springs work and when they fail can save you money and headaches.
Your garage door weighs between 300 and 400 pounds. Without springs, that dead weight would crush your opener motor and make manual operation nearly impossible. Springs do the heavy lifting by storing and releasing energy as the door moves up and down.
There are two main types: torsion springs and extension springs. Torsion springs are mounted horizontally above the door and twist to create lifting force. Extension springs run along the sides of the door and stretch to help lift it. Most modern homes in the Bay Area use torsion springs because they're safer and last longer.
Springs don't last forever. A quality torsion spring is rated for about 10,000 cycles. That's roughly 7 to 9 years if you use your door twice daily. When a spring reaches the end of its life, the metal fatigues and loses its ability to hold tension. Then one day, you hear a loud bang, and the door won't budge.
Metal fatigue is the primary culprit. Every time your door opens and closes, the spring stretches or twists slightly. Over thousands of cycles, microscopic cracks form inside the coil. Eventually, the spring snaps completely.
Other factors speed up failure. Rust and corrosion weaken springs faster, especially in humid climates or if they're not regularly maintained. Lack of lubrication increases friction and accelerates wear. Poor installation or misaligned doors put uneven stress on the springs, causing premature failure.
When a spring fails, you need professional replacement. The cost typically ranges from $300 to $600 per spring, depending on the type and your door's weight. If both springs fail (which happens more often than you'd think), you're looking at $600 to $1,200. For a detailed breakdown, check out our guide on how much garage door springs cost in San Jose.
Installation is not a DIY job. Springs are under immense pressure, and improper handling can cause serious injury. A professional technician has the right tools, knowledge, and insurance to do it safely.

The smartest approach is preventive maintenance. Have your springs inspected annually as part of your routine garage door checkup. A technician can spot early signs of wear, rust, or corrosion before a catastrophic failure occurs.
Listen for warning signs. If your door moves slowly, hesitates, or feels heavier than usual, a spring may be weakening. Some homeowners notice the door closes faster on one side than the other, which suggests uneven spring tension.
If you've already had one spring fail, replace both at the same time. The second spring is likely near the end of its life too. Replacing them together is more cost effective than paying for two separate service calls.
Regular lubrication extends spring life. Use a garage door lubricant spray (not WD-40) on the springs every three to six months. This reduces friction and protects against rust, especially if you live near the coast where salt air speeds corrosion.
Our technicians have replaced hundreds of springs across San Jose and the surrounding Bay Area. We'll diagnose the problem, provide an accurate estimate, and handle the replacement safely. We also inspect your door's balance and opener to make sure the new springs work properly with your system.
If your door uses an older garage door opener, this is a good time to consider an upgrade. A worn opener combined with new springs may not be the best long-term solution. Read more about garage door opener replacement in San Jose to understand whether replacement makes sense for your situation.

How do I know if my garage door spring is broken? A snapped spring usually produces a loud bang. Your door won't open or will feel much heavier. You may also notice the door hanging unevenly or the opener struggling to lift it.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury if mishandled. Professional replacement is the only safe option. Always hire a licensed technician.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 10,000 cycles). Extension springs may last slightly longer. Lifespan depends on maintenance, climate, and door usage frequency.
Is it cheaper to replace one spring or both? Replace both at the same time if one has failed. The second spring is likely near failure too, and a second service call will cost more than replacing both during one visit.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist. Extension springs run along the sides and stretch. Torsion springs are safer, last longer, and are preferred in modern installations.
