Garage Door Springs in Redondo Beach: Torsion vs. Extension Explained
7 min read
Your garage door relies on springs to lift several hundred pounds with ease. When one snaps, the door becomes immobile and potentially dangerous. The confusion starts here: most homeowners don't know they have two spring types to choose from, and picking the wrong replacement wastes time and money. Let's cut through that confusion and explain what torsion and extension springs actually do, why they fail differently, and how to know which one your Redondo Beach home needs.
How Springs Actually Work
A garage door spring doesn't lift the door by itself. Instead, it stores mechanical energy and releases it gradually, counterbalancing the door's weight. Without springs, your opener motor would strain to lift 300 to 400 pounds every single time. Springs reduce that load to just 5 to 10 pounds of actual effort. This is why a snapped spring makes your door impossible to open, even with the motor running.
Springs last roughly 7 to 9 years under normal use. That's not a long lifespan, but it reflects the constant cycle of tension and release. Every opening and closing counts as one cycle. A typical household door opens and closes 3 to 5 times daily, meaning springs endure thousands of load cycles before fatigue sets in.
Torsion Springs: The Standard Choice
Torsion springs mount horizontally above your door opening, perpendicular to the door itself. They twist and unwind to create lifting force. This design is the industry standard for residential doors because it's reliable, efficient, and long lasting.
When a torsion spring snaps, you'll hear a loud bang. The spring suddenly releases all stored energy at once. If you're near the garage, that noise can be startling. Torsion springs fail less frequently than extension springs, and they're easier to balance correctly when replaced. Most new installations in Redondo Beach use torsion springs.
The cost to replace a torsion spring typically ranges from $200 to $400, depending on spring size and quality. A professional can diagnose and replace both springs on the same day, getting your door back in service within hours.
Why Torsion Springs Break
Rust and corrosion weaken the metal over time. Moisture from coastal air in Redondo Beach accelerates this process. Springs also fail from metal fatigue. Each cycle bends the wire slightly, and millions of bends eventually cause it to crack and separate. Poor lubrication or excessive friction speeds up failure. We recommend lubricating springs every six months with a light garage-door-specific oil.
Extension Springs: Less Common but Still Used
Extension springs mount vertically along each side of the door, running parallel to the vertical tracks. They stretch and contract rather than twist. Older homes and lighter doors sometimes use this design. Extension springs are cheaper upfront but typically wear out faster than torsion springs.
A snapped extension spring doesn't usually produce the dramatic bang of a torsion failure, but the door still won't open. Extension springs often come in pairs, and if one fails, the other usually follows within months. We always recommend replacing both at the same time to avoid a repeat service call.
Extension spring replacement costs between $150 and $300 per spring. Because they're more prone to failure, you might replace them twice during the lifespan of a single torsion spring.

How to Know Which Type You Have
Look above your door from inside the garage. If you see a tightly wound spring running horizontally above the opening, you have a torsion system. If you see two springs running vertically along the sides of the tracks, you have extension springs. Never attempt to inspect or adjust springs yourself. They store enormous energy and can cause serious injury if they release unexpectedly.

Don't Delay on Spring Repair
A broken spring affects more than just convenience. A door hanging unevenly from one working spring strains the opener motor and misaligns the tracks. Left unfixed, you'll face much larger repair bills. A snapped spring left in place can also damage the door itself as the weight shifts unevenly.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use. Extension springs often fail sooner, sometimes within 5 to 7 years. Lifespan depends on climate, humidity, lubrication, and use frequency. Coastal areas like Redondo Beach see faster corrosion due to salt air.
Can I replace a garage door spring myself? Springs store enormous amounts of energy. Improper handling causes serious injury or death. Professional replacement is the only safe option. We handle this work daily and have the right equipment and training.
Why do both springs need replacing at the same time? Springs wear together under the same conditions. If one fails, the other is likely near failure too. Replacing both prevents a second breakdown and ensures balanced door operation.
What's the difference between a snapped and stretched spring? A snapped spring breaks completely and stops working immediately. A stretched spring weakens gradually, making the door harder to open or close. Both need replacement, but stretched springs sometimes go unnoticed until failure is complete.
How much does spring replacement cost near me? Torsion spring replacement runs $200 to $400. Extension springs cost $150 to $300 each. Prices vary based on spring quality, door size, and local labor rates. Contact us for a free estimate specific to your door and location.
