Your garage door relies on springs to lift roughly 400 pounds of weight. Two main types exist: torsion springs and extension springs. Torsion springs coil above the door and twist to generate lift. Extension springs run along the sides and stretch to pull the door up. Most modern homes use torsion springs because they're safer, last longer (7 to 9 years), and distribute force more evenly. Understanding which type you have matters when budget and safety are on the line.
Torsion springs mount horizontally above your garage door opening. When the door closes, these springs wind up like a clock spring, storing mechanical energy. When you press the opener button, that energy releases and lifts the door. A single torsion spring can handle the entire weight of a standard residential door.
The engineering is elegant. Because the spring twists rather than stretches, metal fatigue happens more slowly. A quality torsion spring completes roughly 10,000 to 15,000 cycles (open and close) before wearing out. In a typical household opening the door 4 to 8 times daily, that translates to 7 to 9 years of reliable service.
Extension springs hang on either side of the door track. They stretch as the door closes and contract as it opens. Two springs share the load, so each one handles about 200 pounds of force. Because they work under constant tension, they wear faster than torsion springs. Most extension springs last 5 to 7 years before failure.
Another consideration: extension springs require safety cables. If a spring snaps, the cable catches it and prevents the door from falling. This safety feature exists because a snapped extension spring can turn your door into a falling object. Torsion springs don't need cables because they're enclosed above the door and can't suddenly drop.

Torsion spring replacement typically costs more upfront but delivers better value over time. A single torsion spring replacement runs between $200 and $400 in Oakland, depending on spring size and door weight. Because you're replacing one component that lasts longer, your long-term cost per year drops.
Extension spring replacement costs less initially (usually $150 to $300 per spring), but because you need two springs and they fail sooner, you'll visit a technician more often. Over a 10-year period, extension spring owners often spend 30% to 40% more on replacements.
If a snapped spring catches you off guard, same-day emergency service costs extra. Our emergency garage door service in Oakland covers same-day help without the sticker shock, so you're not stuck with a non-functioning door.
Springs hold tremendous tension. A torsion spring under load can release with enough force to break bones or cause serious lacerations. Even if you're mechanically inclined, the risk isn't worth the savings. A technician has proper tools, safety equipment, and experience to work safely.
If your door won't open or you hear a loud bang followed by the door staying closed, a snapped spring is the likely culprit. Don't attempt to force the door open manually or bypass the problem with the opener. Read what to do when a snapped garage door spring stops your door to understand your safest next steps.
Most spring issues require replacement, not repair. A broken spring must be swapped out. A weakening spring (where the door feels heavier or opens slower) should also be replaced, even if it hasn't snapped yet.
The exception: sometimes a spring is fine but needs tension adjustment. That's different from replacement. If you've noticed your door drifting open slightly or closing unevenly, our guide on spring tension adjustment explains why DIY tweaking will hurt you.

When you call for a quote, a technician will identify your spring type, measure the door weight, and inspect for related wear. A legitimate estimate includes labor, the spring itself, and any safety cable replacement. Avoid companies that quote over the phone without seeing your setup.

How do I know if my spring is broken? Your garage door won't open or closes too fast. You may hear a loud bang or snap. The door feels much heavier when you try to open it manually. Never force it; call a technician instead.
Can I replace just one spring if I have two? You can, but we recommend replacing both extension springs together. They wear at similar rates, and replacing only one creates uneven lift and shortens the new spring's life.
How long does spring replacement take? Most replacements take 30 to 45 minutes. Our technicians work efficiently without cutting corners on safety or quality.
Are torsion springs always better than extension springs? For most residential doors, yes. They last longer, require no safety cables, and distribute force more evenly. Older homes sometimes have extension springs by design, but upgrades are possible.
What's the difference between a spring estimate and final bill? Estimates assume one spring replacement. If we discover rust, cable wear, or other damage during work, we'll call and explain any additions before proceeding.
