Torsion Springs vs. Extension Springs

Most garage doors use one of two spring systems, and the difference matters for both safety and price. Torsion springs mount horizontally above the door on a metal shaft and wind up to store energy. Extension springs run along the horizontal tracks on either side of the door and stretch instead of twisting. Torsion springs are more common on doors built or replaced in the last couple of decades, while extension springs still show up on older Visalia homes, especially closer to Downtown, that haven’t had the hardware updated.

Spring Type	Location	Typical Cost (Each)
Torsion spring	Horizontal shaft above the door	$75 to $150
Extension spring	Along the side tracks	$50 to $100

Most doors use two springs working together, and we generally recommend replacing both at the same time even if only one has broken. They wear at close to the same rate, and a mismatched pair puts uneven strain on the door. See our full pricing breakdown for how spring replacement compares to other repairs.

Signs Your Spring Is Close to Breaking

• The door feels noticeably heavier when you lift it manually
• A visible gap opens in the coil of a torsion spring
• The door closes faster than normal or drifts down on its own
• You hear a loud bang from the garage, often mistaken for a car backfiring or something falling
• The opener strains, clicks, or reverses partway through opening
• One side of the door looks like it’s lifting unevenly

For the full breakdown — including the loud-bang warning sign and why you should never attempt this repair yourself — see our guide to spotting a broken garage door spring.

Springs rarely fail without warning entirely. Most give off small signs for days or weeks before they let go completely. If you notice any of these, it’s worth calling before the spring snaps and leaves the door stuck. If it’s actually your opener struggling and the spring looks fine, our opener repair page covers those symptoms instead.

Why Springs Break Down Faster in Visalia

A garage door spring is rated for a certain number of open-and-close cycles, but heat, dust, and cold all shorten that lifespan in their own way here in the valley.

• Summer heat. Metal expands in high heat, and Visalia regularly sees triple-digit summer days. That expansion adds stress to a spring that’s already near the end of its cycle life, which is why we see a real jump in spring failures during the hottest stretch of summer.
• Valley farm dust. Fine agricultural dust works into the coils over time, and a gritty spring wears against itself instead of moving smoothly, shortening its life.
• Winter tule fog. Cold mornings during tule fog season stiffen the metal, and a spring that was already close to its cycle limit is more likely to snap on a cold January morning than a mild October one.

Routine lubrication and a yearly inspection can catch a spring nearing the end of its cycle life before it snaps in your driveway. See our seasonal maintenance checklist for what a yearly tune-up covers.

Do Not Try to Replace a Spring Yourself

A wound torsion spring holds enough tension to cause serious injury if it slips while you’re working on it. This isn’t a job for a standard toolbox, it requires winding bars, vice grips, and knowing the exact wire size and coil length for your door’s weight. If your spring has broken, the safest thing to do is leave the door alone, don’t force the opener, and call a technician. Trying to force a door with a broken spring can also damage the opener’s drive gear, turning a spring repair into a more expensive opener repair too.

How We Replace a Broken Spring

1. We measure the wire size, coil diameter, and length against your door’s actual weight, not just a generic size chart.
2. We give you a firm, written price before any tool touches the door.
3. We replace both springs as a pair when one has failed, so they wear evenly going forward.
4. We test the door’s balance and travel before we leave, and walk you through what we did.

Spring Repair Questions

How long does a spring replacement take?

Most spring replacements are finished in a single visit, generally under an hour once the technician is on site with the right parts.

Do I need to replace one spring or both?

If your door has two springs and one has broken, we generally recommend replacing both, since they’re usually close to the same age and wear at a similar rate. We’ll tell you what we see on your specific door before we start.

Is a broken spring an emergency?

If the door is stuck open, yes, since that’s a security issue. If it’s stuck closed and nothing is trapped inside, it can usually wait for a same day appointment. Call us if you need someone today.

Why did my spring break with no warning?

Sometimes it really does happen with no obvious lead-up, especially with age and cycle count rather than any single event. Other times there were smaller signs, like a slightly heavier door or a faint scraping sound, that are easy to miss until the spring actually lets go.

Can a broken spring damage anything else on my door?

If the opener keeps trying to lift the door after a spring breaks, it can strain or damage the drive gear. That’s the main reason we tell people to stop and call rather than keep pressing the remote.

How much does spring replacement cost in Visalia?

Torsion springs typically run $75 to $150 each, and extension springs $50 to $100 each, most doors use two. See our repair cost guide for other repair costs.

If a single spring just snapped, most standard torsion setups use two matched springs under tension — see our TorqueMaster spring system repair guide if your door uses an enclosed single-spring unit instead.
