Garage Door Springs in San Marino: Torsion vs. Extension (And Why It Matters)
2026-08-20 7 min read A2Z Garage Doors
Your garage door won't open, and your neighbor says the spring snapped. Before you panic or call the first number you find, you need to know which type of spring you have. Torsion and extension springs are completely different mechanisms. They cost different amounts to replace, fail for different reasons, and require different expertise to repair safely.
Understanding Spring Types: Torsion vs. Extension
Most residential garage doors in San Marino use one of two spring systems. Torsion springs sit horizontally above your garage door opening and twist to lift the weight. Extension springs run vertically along the sides of your door frame and stretch as the door lowers. Think of it this way: torsion springs work like a wound clock spring, while extension springs work like a rubber band.
Torsion springs handle the heavy lifting more efficiently, which is why they're becoming the standard in newer homes. They last longer, usually 7 to 9 years with normal use, and they're safer because they contain the tension better. Extension springs typically wear out faster, especially in garages with frequent door cycles.
The price difference matters. A snapped torsion spring costs more to replace than an extension spring because the installation is trickier and requires precise balancing. However, you'll replace it less often. Extension springs are cheaper upfront but may need replacement sooner, and they require safety cables to prevent them from flying across your garage if they break.
Why Springs Fail (And When You're Not at Fault)
Springs don't fail because you're using your garage door wrong. They fail because metal fatigues. Every time you open and close your door, the spring cycles once. After 10,000 to 15,000 cycles (roughly 7 to 9 years for average use), the metal weakens and snaps.
Weather in San Marino accelerates wear. The coastal climate, salt air, and temperature swings stress metal components faster than inland regions. If you live closer to the coast, you might see spring failure closer to the 6 or 7 year mark instead of the full 9.
Poor maintenance speeds failure too. Springs covered in rust, dirt, or lacking lubrication wear faster. If your garage door sounds loud, moves jerkily, or feels unbalanced, that's your warning sign. Don't ignore it. Learn what other warning signs point to needed repairs so you catch problems early.

Cost Reality: What You'll Actually Pay
Extension spring replacement typically runs $150 to $300 per spring, including labor. Most doors have two springs, so budget $300 to $600 total. Torsion spring replacement ranges from $250 to $400 per spring, often $500 to $800 for the pair, because the work is more specialized.
Never pay for a spring replacement without getting an estimate. Reputable shops like Garage Door San Marino provide free quotes that break down parts and labor separately. This transparency helps you spot inflated pricing fast. If someone quotes you $1,500 for a spring replacement without inspecting your door first, get a second opinion.
Same-day service costs more, sometimes 20 to 30 percent above standard rates. That premium makes sense if your door is completely stuck and your car is trapped. It doesn't make sense if you can wait three to five days. Plan ahead when possible.
DIY or Professional Repair?
Don't replace garage door springs yourself. This is the one job where the risk genuinely outweighs savings. A snapped spring under tension can cause serious injury. The torsion rod spins violently when released. Extension springs can whip across the garage. Professionals have winding cones, specialized tools, and insurance.
If you want to save money, focus on maintenance instead. Lubricate springs twice a year with silicone spray. Keep the garage dry to slow rust. Have a professional inspect springs annually if your door is over five years old. Read our maintenance guide for the tune-up your door actually needs to extend spring life.
When replacement is unavoidable, schedule a free quote with our team and compare estimates from at least two companies. You'll know the fair price range and spot overcharges immediately.
Final Steps
A snapped spring feels like an emergency, but it's manageable if you respond smartly. Identify your spring type, get multiple estimates, and hire a licensed professional. Avoid companies that won't provide written quotes or explain the cost breakdown. Quality service costs fair money, not cheap money.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with average use (about 10,000 to 15,000 cycles). Extension springs wear out faster, usually 5 to 7 years. Coastal salt air in San Marino accelerates rust and failure.
Can a snapped spring damage the garage door opener? Yes. If a spring breaks while the door is closing, the opener works harder to move the full weight without spring assistance. This strain shortens opener life. Don't use the door if you hear a loud snap or notice it won't open.
What's the difference in cost between extension and torsion? Extension springs cost $150 to $300 each to replace. Torsion springs run $250 to $400 each due to specialized installation. Torsion lasts longer, so fewer replacements over time offset the higher upfront cost.
Is it safe to use my garage door with a broken spring? No. A broken spring throws the door balance off, stressing the opener and tracks. You risk the door falling suddenly or jamming. Call a professional before opening the door again.
Why can't I replace just one spring? Springs wear together. If one breaks, the other is near failure. Replacing only one creates imbalanced tension, damages the door, and leads to a second breakdown within weeks. Always replace springs in pairs.
