Garage door springs do one job: they counterbalance the weight of your door so it opens and closes smoothly. There are two main types—torsion and extension—and knowing which you have matters when something breaks. A snapped spring won't kill your opener, but it will make your door impossible to lift safely. Let's cut through the confusion and talk about what these springs actually do, why they fail, and what you should expect to pay for a replacement in Brant Rock.
Torsion springs wind around a horizontal shaft above your garage door opening. They twist to store and release energy as the door moves. Most residential doors built in the last 20 years use torsion springs because they're more durable, quieter, and safer than their counterparts.
Extension springs run along the sides of your door track. They stretch and contract to lift the weight. Older homes and lighter doors sometimes use these, and they're cheaper upfront—but they wear faster and require safety cables to prevent injury if they snap.
The type you have determines repair cost, lifespan, and how we approach replacement. Torsion springs typically last 7 to 9 years with normal use. Extension springs? Usually 5 to 7 years. Our team at Brant Rock Garage Doors sees salt air and coastal weather accelerate wear in both types—more on that in a moment.
If you're not sure which type you have, don't guess. Call us at 17814563533 and we'll identify it during a free estimate.
Springs fail because of repeated stress. Every open-close cycle adds wear. A typical door cycles 1,000 to 2,000 times per year, which means your spring handles thousands of stress cycles annually.
Living on the South Shore accelerates failure. Salt air corrodes metal. Moisture seeps into the shaft and spring coils. Temperature swings between winter cold and summer heat cause expansion and contraction. A spring that might last nine years inland can give up in six or seven here in Brant Rock.
You'll notice a snapped spring immediately. The door either won't open, feels heavier than usual, or makes a loud bang when it fails. Don't force it. A snapped spring means zero mechanical advantage—your opener can't lift the door safely, and manual attempts risk serious injury.

Spring replacement cost depends on three factors: which type you need, how many springs require service, and labor time.
Torsion spring replacement runs $250–$400 per spring, including parts and labor. Most residential doors use one or two torsion springs.
Extension spring replacement is less expensive—$150–$250 per spring—but we typically replace both sides at once for safety and balance.
If your door uses both springs and both are worn, replacing them together prevents one from failing weeks after the other. It's more economical long-term.
Local factors matter. Coastal corrosion sometimes means we need to replace the entire shaft assembly, not just the spring. Our labor versus parts breakdown guide walks through how we estimate these scenarios.
Getting an accurate cost requires inspection. Schedule a same-day estimate by calling 17814563533 or visiting our contact page.
You can't prevent spring failure entirely, but maintenance helps. Regular lubrication reduces friction and corrosion. Keeping tracks clean prevents binding that strains springs unnecessarily. In coastal areas like Brant Rock, spring inspection every two years catches corrosion early.
Our balance adjustment guide covers maintenance steps homeowners can handle themselves. But spring service always requires professional tools and training.
Call us if your door feels heavier than usual, makes unusual sounds, or won't open without strain. These are early warnings. Don't wait for a snapped spring to leave you stuck.
If you're preparing for seasonal changes, read our guide on preparing your garage door for hot weather—spring stress increases during temperature extremes.

How do I know if my garage door spring is broken? A snapped spring usually produces a loud bang. Your door becomes very heavy, won't open, or feels unbalanced. Never force a broken spring—call a professional immediately.
Can I replace a garage door spring myself? Torsion springs store hundreds of pounds of tension and can cause serious injury or death if mishandled. Spring replacement requires specialized tools and training. Always hire a professional.
Why do garage door springs fail faster in Brant Rock? Salt air, humidity, and temperature swings on the South Shore accelerate metal corrosion. Springs exposed to coastal conditions wear 20–30% faster than those inland.
How much does spring replacement cost near me? Torsion spring replacement runs $250–$400 per spring. Extension springs cost $150–$250 each. Final cost depends on your door's configuration and whether the shaft needs replacement.
How long do garage door springs last? Torsion springs typically last 7–9 years; extension springs last 5–7 years. Coastal exposure and heavy use reduce these timelines by 1–2 years.
