A customer called last Tuesday morning. Her garage door wouldn't open, and she'd heard a loud bang the night before. I knew instantly: snapped spring. After 15 years on the trucks, I can diagnose that sound in my sleep. What she didn't know was whether she had a torsion spring or an extension spring, and honestly, most homeowners don't. That confusion costs time and money. Here's the straight answer: torsion springs sit horizontally above your door and twist to lift it; extension springs run along the sides and stretch. Both fail eventually, but knowing which one you have matters for safety, cost, and repair speed in West Yarmouth.
Most modern garage doors in West Yarmouth use torsion springs. These coiled metal bars mount perpendicular to your door, above the opening. When you hit the opener button, the springs unwind, storing and releasing energy to counterbalance your door's weight. A typical torsion spring lasts 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles. That's one cycle per open and close.
Torsion springs are safer and more reliable than extension springs. They wear evenly, fail predictably, and rarely snap without warning. When they do snap, the door doesn't drop on your car or fingers. The downside: they cost more to replace because installation requires precision and specialized tools. A torsion spring replacement typically runs $200 to $400 per spring in our area, depending on weight class and brand.
Extension springs stretch and contract along both sides of your door track. You'll see them coiled near the top of each track. They're cheaper to buy and install initially, which is why older homes and budget builders used them. But here's the catch: extension springs can snap violently. When they break, the door can fall hard. That's why safety cables run through the center of extension springs. If the spring snaps, the cable catches the spring and prevents sudden collapse.
Extension springs also wear faster and unevenly. One side might fail before the other, creating imbalance and extra strain on your opener. For more detail on what happens when springs fail, read our guide on snapped garage door springs in West Yarmouth and what to expect.
Cape Cod salt air accelerates corrosion. The moisture and salt particles eat away at metal, weakening the spring's core. You'll notice rust or discoloration on the coils months before failure. Temperature swings also matter. Winter cold makes metal brittle; summer heat stresses the coils. Repeated cycling in humid conditions shortens lifespan by 1 to 2 years.
Improper maintenance speeds up failure too. Springs need periodic lubrication with garage-door-specific oil (not WD-40). Skip that, and friction compounds wear, reducing elasticity.

We recommend replacing both at once to avoid a second repair bill in a few months. Get a free same-day estimate by calling us or filling out our contact form.
Springs fail less often if you maintain your garage door. Lubricate tracks and springs twice yearly. Check for rust or gaps in the coils. Listen for squeaks or grinding sounds. These are early warnings. A door that moves slowly or jerks might signal weak springs. Catch it early, and you'll avoid emergency repairs.

How do I know if my garage door spring is broken? The door won't open with the opener, or you heard a loud bang and the door dropped. The door may hang unevenly or feel heavier than normal. Do not attempt to open it manually; call a technician.
Can I replace a garage door spring myself? No. Springs hold extreme tension. Improper release can cause serious injury or death. Always hire a licensed professional with the right tools and insurance.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely stops door operation. A worn spring weakens gradually, making the door slower or causing jerky movement. Both need replacement, but snapped springs are emergencies.
How much does torsion spring replacement cost in West Yarmouth? Typically $200 to $400 per spring, depending on door weight and brand. Extension springs cost $150 to $300 per spring. Labor is usually included. Call for a specific estimate.
How often should garage door springs be replaced? Most springs last 7 to 9 years with normal use. In coastal areas like West Yarmouth, salt air may shorten that to 5 to 7 years. Regular maintenance and lubrication extend lifespan.
