In our years serving South Gate, we've seen this problem again and again: homeowners don't know what type of garage door springs they have until one snaps. Torsion and extension springs do the same job but fail in completely different ways. Understanding which one sits above your door will save you money, time, and a potential safety scare.
Torsion springs are mounted horizontally above your garage door opening. They twist and untwist to lift the 300 to 500 pounds of dead weight every time you open or close. Think of them like a wound spring toy. Extension springs hang on both sides of the door track and stretch to provide lift. They're under constant tension even when the door is closed. See our guide on garage door springs in south gate: what most homeowners don.
Here's what matters: torsion springs fail silently. Extension springs can snap with force. In South Gate, we get calls from people whose extension spring broke and took out a car window or worse. Torsion springs are safer, but they're more expensive to replace.
Most homes built in the last 20 years use torsion springs. If your house was built in the 1980s or 1990s, you probably have extension springs. Age matters here. Springs last 7 to 9 years under normal use, depending on your local climate and how often you open and close the door.

Both types wear out from constant cycling. Every open and close cycle stresses the metal. In Southern California's heat, metal fatigues faster. Humidity, rust, and lack of lubrication accelerate failure.
Extension springs snap when the metal develops micro-fractures. You'll hear a loud bang, like a gunshot in your garage. Torsion springs wear more gradually. The wire stretches, loses tension, and eventually breaks, but you might not hear much. Your door opener will work harder, and the door won't stay up on its own.
If you've noticed your door sagging slightly or the opener running longer than usual, check our detailed guide on how long garage door springs last in South Gate for warning signs you shouldn't ignore.
Extension spring replacement typically runs $150 to $300 per spring, plus labor. Torsion spring replacement costs $200 to $400 per spring, plus labor. Most doors have one torsion spring or two extension springs.
Total cost with labor usually sits between $300 and $600 for extensions, $400 to $800 for torsion. That seems backward until you factor in lifespan. Torsion springs last longer and perform more reliably. Fewer callbacks means lower lifetime cost. When you need a same-day estimate, we can tell you exactly what your door requires.

Extension springs are fitted with safety cables that run through the center of each spring. If the spring breaks, the cable catches the broken pieces. Without that cable, a snapped extension spring can whip across your garage. It has hurt people.
Torsion springs don't use safety cables. They're engineered to fail less violently. However, they're under extreme tension. Never attempt to adjust or replace a torsion spring yourself. The tension can cause serious injury. We've seen firsthand what happens when someone tries a DIY fix.

Stop using the door immediately. A snapped spring means the opener is working overtime. It can burn out the motor in days. Call a professional to inspect and replace the broken spring.
Do not try to manually lift the door. Without a working spring, it's dead weight. You'll pinch your fingers or worse.
If you have a snapped spring right now, that's an emergency. We respond to South Gate and Long Beach with emergency calls during business hours and after.
If you're replacing an extension spring system, consider upgrading to torsion. Yes, the upfront cost is higher. But torsion springs last longer, are safer, and give you peace of mind. Over 10 years, you'll actually spend less.
If you already have torsion, stick with it. Changing system types requires door modifications and new hardware. Not worth the expense or disruption.

Can I replace just one spring if the other is still good? No. Springs wear in pairs. If one has snapped or is failing, the other is right behind it. We always replace both at the same time to avoid a second failure in a few weeks.
How do I know if I have torsion or extension springs? Look above your door opening. Torsion springs are thick, horizontal coils centered above the door. Extension springs are thinner, run along both sides of the track, and have pulleys at the ends.
Is there a way to make springs last longer? Regular lubrication helps. Avoid opening and closing the door excessively. Maintenance tune-ups catch wear before failure. Heat and humidity in South Gate accelerate wear, so annual inspection is smart.
What's the warranty on replacement springs? We offer 2 to 5 year warranties depending on the spring type and manufacturer. Cheap springs fail faster. Quality springs cost more but outlast budget options by years.
Can the garage door opener damage springs faster? Yes. An old or misaligned opener creates uneven tension on springs. If your opener is more than 15 years old, springs may wear faster. We can check that during your inspection.
