A snapped garage door spring means your door won't open, and you can't ignore it. In our 15 years serving Chula Vista, we've seen this problem again and again. A torsion or extension spring typically lasts 7 to 9 years before it fails, and when it does, replacement is the only real fix. This guide covers what causes failure, realistic repair costs, and how to get back on the road fast.
Your garage door springs work harder than most homeowners realize. Every single day, they support roughly half the weight of your door as it opens and closes. A standard residential door weighs 300 to 400 pounds. That's thousands of cycles per year, and springs have a finite lifespan.
Chula Vista's coastal climate doesn't help. Salt air, temperature swings between morning and afternoon, and humidity all accelerate corrosion on metal springs. We've pulled springs from garages near the water that looked like they'd been sitting for decades, even though they were only five or six years old. If you live closer to the coast, expect wear to happen faster.
Rust is the silent killer. Once corrosion starts on a spring's surface, it weakens the metal from the inside out. A small crack becomes a complete break under load, usually when you're backing out of the driveway.
Not all springs are the same. Understanding which type you have helps you understand repair costs and replacement timelines.
Torsion springs mount horizontally above your door opening. They twist as your door moves, and they're the most common type in residential garages. Torsion springs are more durable, safer to work with, and usually last longer than extension springs.
Extension springs hang vertically on either side of your door. They stretch as the door lowers and compress as it rises. They're cheaper to install but fail more often, especially in homes where the door gets heavy use.
Both types need professional replacement. Attempting a DIY fix is genuinely dangerous. A snapped spring under tension can snap back and cause serious injury.
Cost varies by spring type, your door size, and whether you need one or both springs replaced. On average, Chula Vista homeowners pay between $250 and $500 per spring for labor and parts combined.
A single torsion spring replacement runs $300 to $450. Extension springs cost $150 to $300 each. If both springs have failed (which happens), budget for two replacements.
We always recommend replacing both springs at the same time, even if only one has snapped. The second spring is under the same stress and will likely fail within months. It costs less to do both now than to call us back for an emergency repair in July.

Many homeowners don't realize that a broken spring affects more than just the door's movement. Your opener relies on springs to help lift the door. When a spring snaps, your opener has to work much harder, and it can burn out faster than it should.
If you've already replaced your opener once, a failing spring may have been the real culprit. Check your springs first before investing in a new motor. We've saved customers hundreds by catching this connection early.

You can't stop springs from eventually wearing out, but proper maintenance slows the process. Annual lubrication with garage door spray reduces friction and corrosion. Wipe down your springs twice a year if you live near the coast. Keep your garage as dry as possible during the winter months.
Also, prepare your garage door for seasonal changes. Temperature shifts put extra stress on springs, so a little preventive care pays off.
If your door won't open or you hear a loud bang from the garage, don't force it. A snapped spring is the most likely cause. Call us at 619-639-1299 or get a same-day estimate online. We'll send a technician to confirm the diagnosis and give you a firm repair cost before any work begins.
Broken springs are fixable, and they're fixable fast. The sooner you call, the sooner your door works again.
How do I know if my garage door spring is broken? Your door won't open with the remote or wall button, or it opens very slowly and unevenly. You may hear a loud bang or snap from inside the garage. Never force the door open. Call a professional to confirm and replace the spring.
Can I replace a garage door spring myself? No. Springs are under extreme tension, and a DIY mistake can cause serious injury or death. Professional replacement takes 30 to 60 minutes and includes safety testing. Always hire a licensed technician.
How long do garage door springs last? Most residential torsion springs last 7 to 9 years with normal use. Extension springs may fail sooner, especially in high-use garages. Coastal environments like Chula Vista see faster wear due to salt air and humidity.
Is it cheaper to replace one spring or both? Replace both at the same time. If one has snapped, the other is under the same stress and will fail soon. Doing both now costs less than two separate service calls and avoids another emergency shutdown.
What's the difference between emergency and regular spring replacement? Same-day weekday service is standard. Emergency after-hours or weekend calls include a trip charge and higher labor rates. Call early in the day to avoid extra fees.
