Let's cut through the confusion about garage door springs. Most homeowners don't know whether they have torsion or extension springs, let alone what happens when one snaps. After 15 years working on garage doors across Mattapoisett and the South Coast, I've learned that understanding your spring type is half the battle when something goes wrong.
Your garage door uses one of two spring systems: torsion or extension. This matters because they work completely differently, fail differently, and cost different amounts to replace. See our guide on garage door openers in mattapoisett: what most homeowners don.
Torsion springs sit horizontally above your garage door opening. They twist and untwist to counterbalance the door's weight. When you open the door, the spring winds tighter. When you close it, the spring unwinds. This design is safer, more durable, and more common in newer homes. Torsion springs typically last 7 to 9 years under normal use.
Extension springs run along the sides of your door tracks. They stretch and contract as the door moves up and down. You'll see them hanging vertically on both sides of the opening. Extension springs are older, less expensive upfront, but they wear faster and tend to be noisier. They also last about 7 to 9 years, though some fail sooner depending on humidity and salt air exposure. Read about garage door lubrication in mattapoisett: the one maintenance task that saves everything.
Here in Mattapoisett, our coastal climate affects spring life. The salt air accelerates rust on both types, which is why I recommend regular lubrication. Check out our garage door lubrication guide for Mattapoisett) to learn what actually prevents early failure.
Stand in your garage and look at your door from inside. If there's a horizontal spring running above the door frame, you have torsion. If springs run vertically along both sides of the tracks, you have extension springs. This simple check tells you exactly what you're dealing with before you call for an estimate.
Torsion springs contain far more tension. Never try to adjust or touch them yourself. Extension springs have safety cables running through them for a reason. When an extension spring snaps, that cable catches it and prevents injury. Both systems are under extreme pressure, and a snapped spring is a genuine emergency.

Springs don't just snap randomly. Wear is predictable. Every cycle (open and close) stresses the metal a little more. After thousands of cycles, metal fatigue takes over. Rust accelerates this process dramatically. That's why coastal homes in Mattapoisett see earlier failures than homes inland.
Poor maintenance speeds failure too. A door that's not lubricated properly forces the springs to work harder. Misaligned tracks add extra strain. Even a slightly bent track can shorten spring life by years.
I've also seen homeowners ignore the first warning sign: your door becomes harder to open, or it won't stay open on its own. That's the spring losing tension. Many people live with this for weeks before calling. By then, the other spring is usually close behind.
One snapped spring costs less to replace than two. This isn't a guess. It's physics and experience. If your door is 7 to 9 years old and one spring fails, the other is right behind it. Replacing both at once saves labor costs and prevents a second emergency call in two months.

Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if handled incorrectly. Always hire a licensed technician. This is not a DIY job.

How long do garage door springs last? Most springs last 7 to 9 years under normal residential use. Coastal salt air, poor maintenance, and frequent cycling can shorten lifespan. Regular lubrication extends life.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist. Extension springs run along tracks and stretch. Torsion is safer, more durable, and more common in new installations.
