In our 15 years serving Cambridge, we've seen this problem again and again: homeowners wake up to a garage door that won't open, and nine times out of ten, it's a snapped spring. Most people have no idea what type they have or why it matters. The truth is simple. Your garage door uses either a torsion spring or an extension spring, and each one fails differently, costs differently, and needs different replacement timing.
Your garage door weighs 300 to 500 pounds. It doesn't move itself. A spring system counterbalances that weight, making it possible for your opener to lift the door with minimal effort. Without springs, your opener would burn out in weeks, or your door would crash down and potentially injure someone. See our guide on brand comparison: what every homeowner should know.
Springs handle extreme tension and release thousands of times over their lifespan. That constant stress is why they wear out. A snapped spring means your door is stuck, your opener can't function safely, and you need professional help fast. This isn't a DIY fix. Garage door springs operate under 200+ pounds of pressure. A loose spring can cause serious injury.
Torsion springs mount horizontally above your garage door opening. They twist as your door moves, storing and releasing energy through rotational force. Most modern homes in Cambridge use torsion springs because they're more durable, last longer, and create smoother door operation.

Extension springs run vertically along each side of your door frame. They stretch and contract like a rubber band. Older homes, especially those built before 2000, tend to have extension springs. They're less expensive upfront but typically wear out faster than torsion systems.
When a torsion spring fails, the door becomes immovable. When an extension spring snaps, the door may still open slightly or jerk unevenly. Either way, you need a same-day replacement from someone who knows what they're doing.

Springs last 7 to 9 years under normal use, sometimes longer if you maintain them well. Climate plays a role here. Massachusetts winters are hard on garage doors. Cold temperatures make metal brittle, and freeze-thaw cycles stress springs faster than they would in milder climates. We've replaced springs that failed at year five in Cambridge homes simply because of winter cycling.
Your usage matters too. If you open and close your door five times daily, you're putting more stress on the spring system than someone who opens it twice. Each cycle counts toward the spring's life expectancy.

A torsion spring replacement typically runs $200 to $400 per spring, including labor. Extension springs cost $150 to $300 per pair. Most doors have one torsion spring or two extension springs, so budget accordingly.
If both springs have failed (which happens more often than you'd think), expect to replace both at once. That's the smart move. If one spring is at the end of its life and the other snaps, the remaining spring will fail within weeks.
