Garage Door Spring Types in El Segundo: Torsion vs. Extension Explained
7 min read
Your garage door won't budge. You peer up and notice a snapped spring, coiled uselessly above the door frame. Now comes the real question: was it a torsion spring or an extension spring, and does it actually matter? The answer is yes, it matters a lot. Torsion springs sit horizontally above the door and twist to lift it, while extension springs run along the sides and stretch. Choosing the wrong replacement will cost you time, money, and a garage door that won't work safely.
Torsion Springs: The Heavy Lifters
Torsion springs are the workhorses of most modern garage doors. They mount on a metal rod above your door opening and use rotational force to counterbalance the door's weight. When you open the door, the spring tightens. When you close it, the spring unwinds, helping lower the door smoothly. See our guide on garage door springs in el segundo: maintenance tips to avoid costly repairs.
Here's what makes torsion springs different. They're wound incredibly tight and store massive amounts of energy. A single torsion spring can support a 300 to 400 pound garage door on its own. That efficiency is why professional installers prefer them for heavier, newer doors. They're also more durable. Most torsion springs last 7 to 9 years with normal use, sometimes longer if you stick to a maintenance schedule.
The trade-off? Torsion springs are dangerous to replace yourself. The tension is extreme. A snapped torsion spring can launch with enough force to cause serious injury. This is why I always recommend calling a professional for torsion spring replacement. Read about garage door springs in el segundo: what breaks, why it costs, and how to fix it.
Extension Springs: The Older, Simpler Option
Extension springs work differently. They're installed on either side of your garage door opening, running along the tracks. Instead of twisting, they stretch and contract. When the door opens, the springs extend. When it closes, they compress back to their resting state.
Extension springs are lighter duty than torsion springs. They work best on lighter doors, typically under 300 pounds. Many older El Segundo homes still have extension spring systems. If your garage door is 15 to 20 years old, you likely have extensions.
One advantage of extension springs is that they're slightly easier to understand. You can see them work. But here's the catch: they fail more often than torsion springs. Because they're stretched and compressed constantly, they wear out faster. Most extension springs last 4 to 7 years. When one breaks, you often need to replace both as a pair to keep the door balanced.

How to Tell Which Type You Have
Walk into your garage and look above the door. Is there a tightly wound spring sitting horizontally on a rod, centered above the opening? That's torsion. Do you see springs running vertically along the left and right tracks, near the pulleys? Those are extension springs.
When in doubt, take a photo and send it our way. We'll identify your spring type and give you an honest estimate. No guesswork, no upselling.
The Cost Difference
Extension springs typically cost less to replace than torsion springs. A single extension spring runs $150 to $300, but you usually need two. Torsion springs range from $200 to $400 per spring, depending on the door weight and spring rating. If you need a same-day estimate for spring replacement cost, we're here to help you understand what's fair.
Labor matters too. Professional torsion spring installation takes 1 to 2 hours. Extension spring work is sometimes faster, but safety is never rushed. This is not a DIY project, period.
What Happens When Springs Fail
A snapped spring doesn't just stop your door from opening. It puts all the weight on your garage door opener, which isn't designed to lift 300+ pounds alone. The opener burns out. Your door gets stuck halfway. In coastal areas like El Segundo, salt air accelerates rust on metal springs, making failure more likely. If you've been putting off maintenance on your garage door springs, now's the time to act.
Why Professional Help Is Non-Negotiable

Frequently Asked Questions
How long do garage door springs typically last? Torsion springs last 7 to 9 years with regular use. Extension springs typically last 4 to 7 years. Lifespan depends on door weight, climate, and how often you open and close the door. Salt air in coastal areas like El Segundo can reduce lifespan by 1 to 2 years.
Can I replace just one spring if the other is still working? For extension springs, no. You should replace both as a pair to keep the door balanced. For torsion springs, it depends on age and condition. We recommend replacing both if either is near the end of its life to avoid a second failure soon after.
What's the danger with DIY spring replacement? Springs store enormous energy. A snapped or misaligned spring can launch, causing severe cuts, broken bones, or eye injuries. Professional technicians have the tools and training to handle this safely. It's not worth the risk.
How much does spring replacement cost in El Segundo? Extension springs cost $300 to $600 for both. Torsion springs cost $400 to $800. Labor adds $150 to $300 depending on complexity. Call us for a transparent, no-charge estimate.
Why does my garage door spring keep breaking? Frequent use, improper maintenance, and coastal salt air all shorten spring life. If you're experiencing repeated failures, have a professional inspect your door balance and opener condition.
