Your garage door won't open, and you're staring at a snapped spring. Before you panic about cost, you need to know one thing: which type of spring failed. Torsion and extension springs aren't the same, and replacing the wrong one wastes money. In our years serving San Leandro, we've seen this problem again and again. The good news? Understanding the difference saves you hundreds.
Springs carry the weight of your garage door. A typical door weighs 300 to 600 pounds. Without springs, the opener motor would burn out instantly trying to lift that load. Springs counterbalance the door, making it easier and safer to open and close.
Springs fail because they work hard, every single day. Each cycle stretches or twists the metal. After about 7 to 9 years of use (roughly 10,000 to 15,000 cycles), metal fatigue sets in. Rust in our Bay Area climate accelerates this wear. When a spring snaps, your door becomes dead weight. The opener can't lift it. You're stuck.
The lifespan depends on spring type and how often you use the door. A family that opens their garage four times daily will see spring failure sooner than someone who uses it twice.
Torsion springs mount horizontally above your garage door opening. They twist to create lift. When you pull the door opener, the springs unwind slightly, releasing stored energy that helps raise the door.
Torsion springs are the default choice for residential doors in San Leandro. Why? They last longer, operate more smoothly, and take up less space. A quality torsion spring lasts 7 to 9 years with regular use. They handle heavy doors better than extension springs.
The trade-off: torsion springs cost more upfront than extension springs. A single torsion spring replacement typically runs between $150 and $300, depending on the door's weight and your local market. Both springs usually fail around the same time, so you'll often replace a pair.
Extension springs hang vertically on both sides of your door opening. They stretch to provide lift. When the door opens, these springs extend; when it closes, they contract.
Extension springs are cheaper initially. Single spring replacement costs $100 to $200 in San Leandro. They work fine for lighter residential doors and smaller garages.
But here's the catch: extension springs wear out faster. You're looking at 5 to 7 years before failure, not 7 to 9. They also create more friction and noise. Safety cables run through extension springs to prevent them from flailing dangerously if they snap. That extra hardware adds complexity to repairs.

Look above your garage door opening. Torsion springs are horizontal and coiled like a watch spring. Extension springs hang vertically and look like long metal snakes. One torsion spring balances most single-car doors; extension setups use two springs.

A torsion spring replacement in San Leandro typically costs $200 to $400 for the part and labor, assuming no additional damage. Extension spring replacement runs $150 to $300 total. If both springs fail (common), double those figures.
Emergency or same-day service carries a small premium. If you need springs fixed on a Sunday evening, you'll pay more than a Tuesday afternoon job. That's industry standard everywhere.
The smart move? Don't wait for one spring to snap before replacing the other. Springs fail in pairs because they age together. Replacing both at once costs less than two separate service calls and keeps your door balanced.

Never attempt spring replacement yourself. Garage door springs hold massive amounts of tension. A snapped spring can slice skin or break bones. The door itself can crash down without warning.
A trained technician has the right tools, experience, and insurance to handle the job safely. They'll inspect the opener, rollers, and tracks while they're at it. Small problems caught early prevent big repair bills later.
If your door is making noise, moving slowly, or stuck partway open, springs may be the culprit. Schedule a free quote today and let us diagnose the issue with no obligation.
Knowing whether you have torsion or extension springs helps you plan ahead. Torsion springs last longer but cost more per replacement. Extension springs are cheaper but fail sooner. Neither choice is wrong. It depends on your garage door's weight, your budget, and how long you plan to stay in the home.
If you're selling soon, a budget replacement works fine. If you're staying 10 more years, investing in torsion springs makes sense.

How do I know if my garage door spring is broken? The door won't open or opens very slowly. You may hear a loud bang or snap. The door might be stuck halfway or resting on the ground. Never force it. Call for professional help immediately.
Can I open my garage door manually if the spring is broken? Not safely. A broken spring means the door's full weight is on the opener or your hands. This strains both and risks injury. Wait for professional repair.
Do both springs always fail at the same time? Usually yes, since they age together. Replacing both at once is more cost-effective than two separate calls. It also keeps the door balanced and operating smoothly.
