Garage Door Springs in Berkeley: Torsion vs. Extension and When to Call
7 min read
In our years serving Berkeley, we've seen this problem again and again: a homeowner hears a loud bang, their garage door won't budge, and they're stuck wondering what just broke and whether it's safe to touch. Nine times out of ten, it's a snapped spring. Understanding the two main types of garage door springs, torsion and extension, helps you recognize trouble early and know exactly who to call.
What Are the Two Types of Garage Door Springs?
Your garage door relies on a spring system to counterbalance its weight. Most doors weigh between 300 and 500 pounds, and springs are engineered to handle that load thousands of times over. The two designs work differently, and knowing which one you have matters for repair costs and safety.
Torsion springs wind around a horizontal rod above your door opening. They store energy through twisting motion. When you open the door, the spring unwinds slowly and steadily, making the lift feel smooth and controlled. Torsion springs are more durable, last longer (typically 7 to 9 years with regular use), and are safer because they're contained above the door frame.
Extension springs run along the sides of your door tracks, parallel to the horizontal tracks. They stretch and contract, pulling cables that help lift the door. Extension springs wear out faster than torsion springs, usually lasting 5 to 7 years, and they pose a higher safety risk because they can snap suddenly and whip across the garage.
Why Springs Fail and What Happens When They Break
Springs wear out because they cycle constantly. Every time you open and close your door, that's one cycle. A typical household opens and closes their garage door 3 to 5 times daily. Over months and years, metal fatigue sets in. The spring loses its ability to hold tension, and eventually, it snaps.
When a torsion spring breaks, you'll hear a loud crack or bang. Your door may drop suddenly or feel unbalanced. When an extension spring snaps, the door can drop even faster, and the broken spring can thrash around dangerously. This is why you should never attempt a DIY repair on springs. The stored energy is extreme, and one slip can cause serious injury.
Cold weather, moisture, and salt air in the Berkeley area also accelerate spring wear. The Bay Area's humidity and occasional frost cycles stress metal more than steady climates do.
If your door won't open, feels heavier than usual, or you've heard a loud crack, you likely have a snapped spring. Schedule a free quote right away to prevent the door from falling or leaving your home vulnerable.

Cost and Repair vs. Replacement
Spring replacement isn't cheap, but it's necessary. A single torsion spring replacement typically costs $150 to $300, while both springs (which we recommend for balance and longevity) run $300 to $600. Extension springs cost less individually, around $100 to $200 each, but you'll often replace both sides.
The good news: a spring replacement is usually much cheaper than replacing the entire door. If you're wondering whether to repair or replace your whole door, we've written a detailed comparison that covers the cost breakdown and long-term value. Read our guide on repair vs. replace for clarity on that decision.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (3 to 5 cycles per day). Extension springs wear faster, usually 5 to 7 years. Frequency of use, climate, and maintenance affect lifespan. Regular lubrication and inspection extend spring life.
Can I replace a garage door spring myself? No. Spring replacement requires specialized knowledge, tools, and extreme caution. Stored spring energy can cause serious injury or death if mishandled. Always hire a licensed professional. The cost of professional service is worth the safety guarantee.
What does a snapped spring sound like? A loud bang or crack, like a gunshot or firework. You may also hear a whipping sound as the spring or cable flails. If you hear this noise, stop using the door immediately and call for professional repair.
Is a snapped spring an emergency? Yes. A broken spring prevents door operation and weakens home security. It also risks dropping the door suddenly, damaging the opener or vehicles. Call for same-day repair service right away.
Do I need both springs replaced at the same time? Yes. If one spring has failed, the other is likely near failure. Replacing both ensures balanced, safe operation and prevents a second costly repair in the near future.
