Here's what most homeowners don't realize about garage door springs in Mountain View: you probably have one of two types, and they fail in completely different ways. Understanding which system your door uses could save you hundreds of dollars and keep you safe when something goes wrong. I've been in this business long enough to know that a snapped spring at midnight is nobody's idea of a good time.
Your garage door uses either a torsion spring or extension springs. These are not interchangeable, and mixing them up is a mistake I see happen more often than I'd like.
Torsion springs wind tightly around a metal rod above your door opening. They use rotational force to lift the door's weight. Most modern homes built in the last 20 years use torsion systems. They're safer, more durable, and last 7 to 9 years with normal use.
Extension springs hang vertically on both sides of the door opening. They stretch as the door closes and contract as it opens. These are older and more common in homes built before 2000. They're cheaper upfront but wear out faster and pose a higher safety risk if they snap. When an extension spring breaks, the cable can whip across your garage at dangerous speeds.
If you're unsure which type you have, look above your door. A thick rod with a spring wound around it means torsion. Coil springs running alongside cables on each side means extension.
Springs don't just break randomly. They fail because of normal wear, rust from humidity (common in the Bay Area), or poor maintenance. I've replaced springs that lasted only three years because homeowners never lubricated them.
A snapped spring will announce itself loudly. Your door will either not open at all or crash down suddenly. Never try to force a door with a broken spring. The opener can't handle the full weight, and you risk serious injury.
Early warning signs include a door that feels heavier than usual, jerky movements, or a loud bang inside the garage. Read our post on warning signs your garage door needs professional repair to catch problems before they escalate into safety hazards.

This is where honesty matters. I won't charge you for a repair you don't need, and I won't sell you a cheap solution that fails in six months.
A torsion spring replacement typically runs $250 to $400 per spring, depending on the door's weight and your home's specifications. Most residential doors have one spring, but heavier commercial doors may need two. Labor is usually $150 to $200. Extension springs cost $100 to $200 per spring, but they wear faster.
The real cost isn't the initial repair. It's what happens when you ignore maintenance. Check out our detailed guide on garage door spring costs and replacement timing to understand what you'll actually pay.
Many homeowners ask about DIY replacement. Don't. Garage door springs are under extreme tension. A slip during installation can cause serious injury or death. I've seen too many amateur jobs end badly. Let a licensed technician handle this. When you schedule a free quote with us, we'll give you an honest estimate with no surprises.
Springs last longest when you maintain them. That means lubricating the spring, rod, and hinges twice a year with a silicone-based lubricant. Avoid WD40 or general oils that attract dust and rust.
Check your springs monthly for visible damage, unusual noises, or signs of rust. In Mountain View's climate, rust develops faster than in drier regions. Preventive maintenance can add two to three years to your spring's lifespan.
If you're not comfortable doing this yourself, our maintenance program covers seasonal inspections and lubrication. It costs less than a single emergency repair.
Call immediately if your door won't open, closes unevenly, or you hear a loud snap or bang. Don't wait for the second spring to fail. Most modern doors use two springs in tandem, and when one breaks, the other is usually close behind.

The bottom line: springs fail. It's not a matter of if, but when. Being prepared means knowing your spring type, keeping up with maintenance, and having a trusted technician's number on hand. When you need us, call 626-657-2075 or contact us online for a no-pressure estimate.
How long do garage door springs actually last? Torsion springs typically last 7 to 9 years with regular use and maintenance. Extension springs wear out faster, usually within 5 to 7 years. Lifespan depends on how often you open and close your door, climate conditions, and maintenance consistency.
Can I replace just one spring if the other is still working? Not recommended. When one spring fails, the other is usually under the same stress and close to failure. Replacing both at once prevents a second breakdown weeks later and saves on labor costs.
Is a snapped spring an emergency? Yes. A broken spring prevents your door from opening safely and can damage the opener. Never attempt to manually lift the door. Call a professional immediately.
What's the difference between a cheap spring replacement and a quality one? Cheap springs are often lower-grade metal and fail faster. Quality springs have better material and consistent winding. The price difference is small, but the lifespan difference is significant.
Do I need to replace springs if my door is old? If your door is functional and springs are intact, no. But if you're considering a new door anyway, our opener and spring installation options can modernize your system and improve safety features.
