Garage Door Spring Types in Palos Verdes Estates: Which One Do You Have?
2026-07-28 7 min read A2Z Garage Doors
Your garage door relies on one of two spring types to lift that heavy door dozens of times a year. Torsion springs sit above the door and twist to provide lift; extension springs hang on either side and stretch. The type you have determines repair cost, replacement timeline, and whether a snapped spring means your door stops working entirely. Most homes in Palos Verdes Estates use torsion springs, which last 7 to 9 years with normal use.
Understanding Torsion Springs
Torsion springs do the heavy lifting. A single spring wraps around a metal rod above your garage door opening and twists as the door opens and closes. This rotation stores and releases energy in a controlled way, making the door feel almost weightless to your opener.
Here's why torsion matters: when it snaps, your door won't budge. The spring can't transfer energy anymore, and your opener can't muscle the full weight on its own. A typical residential torsion spring breaks without warning, usually after years of cycling. You'll hear a loud bang. That's the spring giving up, not an explosion, but it sounds dramatic enough to scare you.
Torsion springs are built for durability. Quality springs handle 10,000 to 15,000 cycles (one open and close equals one cycle). At two to three cycles per day, that's roughly 7 to 9 years of service. Coastal salt air in Palos Verdes can accelerate rust and wear, so springs here sometimes fail closer to the 6 or 7-year mark.
The cost to replace a snapped torsion spring runs between $150 and $300 per spring, depending on diameter and wire gauge. Most residential doors have one spring, sometimes two for heavier doors. Don't let anyone charge you for both if only one failed.
Extension Springs: The Secondary Option
Extension springs work differently. They're mounted on either side of the door track and stretch as the door opens. Pulleys and cables redirect the spring tension, making the system less efficient than torsion but cheaper upfront.
Fewer homes in Palos Verdes Estates use extension springs for new installations, but plenty of older homes still have them. They're gentler on the garage door opener because the load is split between two springs. However, they need safety cables running through them. If an extension spring snaps, that cable catches it and keeps it from flying across your garage.
Extension springs last about the same lifespan as torsion springs (7 to 9 years), but they're more prone to dust and moisture buildup in the pulleys. Our coastal humidity doesn't help. These springs cost less to replace, usually $100 to $200 each, but you'll often need to replace both at the same time to keep tension balanced.

How to Know Which Type You Have
Look above your garage door. If you see a horizontal rod with a spring wound around it, you have torsion. If you see springs hanging vertically on each side of the door with cables running through them, those are extension springs.
Don't touch either one. Springs under tension can cause serious injury. If you need to know the exact spec for your door, we can schedule a free quote and identify everything during our visit.
When Springs Fail: What Happens Next
A snapped spring means your garage door won't open. Your opener will try, but it'll sound strained or give up entirely. You're looking at an emergency service call unless you want to manually lift a 300 to 400-pound door yourself.
Some homeowners attempt DIY replacement. I've seen it go wrong too many times. Springs store enormous energy. Improper installation or incorrect tension can send a spring end flying or cause the door to fall unexpectedly. For safety and warranty reasons, professional spring replacement in Palos Verdes Estates is the right call.
Our team handles torsion and extension spring replacement with the same precision. We test tension, verify the door balance, and check the opener's force settings before we leave. Most jobs finish in under an hour, and we offer transparent pricing upfront. No surprises.
The Bottom Line
Both spring types serve the same purpose but work in different ways. Torsion springs are stronger and more common in modern homes. Extension springs are older but still functional. Either way, they wear out. When yours does, call a professional.
Don't wait for a spring to snap in the middle of the week when you need to get to work. If your door feels sluggish, makes noise, or you can't remember when the springs were last serviced, reach out today. Contact us for a same-day estimate and we'll get your door working reliably again.
Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with typical use (2 to 3 cycles per day). Coastal salt air and high humidity can shorten lifespan to 6 to 7 years. Regular lubrication helps extend service life.
Can I replace a garage door spring myself? Not safely. Springs store enough energy to cause serious injury or death. Professional replacement ensures proper tension, balance, and safety cable installation. DIY attempts often result in emergency service calls costing more.
What does it cost to replace garage door springs? Torsion springs run $150 to $300 per spring. Extension springs cost $100 to $200 each. Most homes need one torsion spring or two extension springs. We provide a free estimate before any work begins.
Why did my spring break without warning? Springs weaken gradually through thousands of cycles. Rust from coastal moisture, temperature changes, and normal wear accumulate until the metal fatigues and snaps. Maintenance and lubrication slow this process.
How do I know if a spring is broken? Your garage door won't open, or the opener strains and makes unusual noise. You may hear a loud bang when it fails. Never force the door open. Call for professional service immediately.
