If you've ever dealt with a stuck garage door or heard a loud bang from your garage, you probably have a spring problem. But here's what most homeowners don't realize: not all garage door springs are the same. The type you have determines how your door moves, how much it costs to replace, and what safety risks you face. Let me walk you through both types so you know exactly what's happening above your head.
Your garage door uses one of two spring systems: torsion or extension. These aren't interchangeable, and mixing them up can lead to a door that won't open, won't close, or worse, comes crashing down unexpectedly.
Torsion springs are mounted horizontally above your garage door opening, right along the header. They twist and untwist as your door moves up and down. Think of them like the spring in a wind-up toy. Most modern homes in Billerica and surrounding areas use this system because it's safer and more durable. Torsion springs typically last 7 to 9 years with normal use.
Extension springs hang vertically on each side of your door, running along the tracks. They stretch and contract to lift the door. These are older, less stable, and require safety cables running through them (because a snapped extension spring can whip across your garage like a dangerous projectile). If your house was built before the late 1990s, you likely have extensions.
The spring type affects repair cost, safety, and how quickly we can help you. A torsion spring replacement typically runs higher than an extension replacement because the system is more complex to balance. But torsion springs are worth the investment. They distribute weight more evenly, put less strain on your opener, and don't require safety cables.
If you have a snapped spring right now, you can't simply go to a big-box store and grab a replacement. Springs are precision components. The wire thickness, coil count, and diameter must match your door's weight exactly. This is why I always recommend getting a professional estimate before assuming cost. We can assess which type you have, measure the exact specifications, and tell you what to budget.

Walk into your garage and look up. If you see a thick metal rod running horizontally above the door with coils wrapped around it, that's a torsion spring. If you see two springs running vertically on the left and right sides of the door tracks, those are extensions.
Don't try to adjust, inspect, or touch either type yourself. Springs hold enormous tension (often 200+ pounds per spring). A single mistake can cause serious injury or property damage. Even a small slip while removing one side can launch the other side across your garage at high speed.

A failing spring doesn't always snap suddenly. You'll often notice warning signs first. The door becomes harder to open, moves slowly, or feels unbalanced. You might hear creaking or groaning sounds. Sometimes the door closes faster than it opens because one spring has already lost tension.
These symptoms mean you should schedule a service call soon, not wait for a complete failure. A door with a broken spring puts extra stress on your opener and can cause it to burn out prematurely. Learn more about choosing the right garage door opener type for safety to understand how springs and openers work together.
When we replace springs, we don't just swap out the old one. We inspect the entire system: tracks, rollers, cables, and hardware. We test the door balance and adjust the opener if needed. We also check that your door has proper safety features like photo eyes and auto-reverse mechanisms.

What's the difference in cost between torsion and extension spring replacement? Torsion springs typically cost more to replace because the installation requires precise balancing and specialized tools. Extension springs are simpler but less safe long-term. Exact pricing depends on your door weight and local labor rates.
Can I replace just one spring if the other is still working? No. Springs wear at similar rates. If one has failed, the other is near the end of its life. Replacing both at once ensures balanced performance and prevents another failure in weeks.
How often should garage door springs be replaced? Most torsion springs last 7 to 9 years with average use (one or two cycles per day). Extension springs last slightly less. Frequency depends on how often you open and close your door.
Are safety cables required on extension springs? Yes, absolutely. Safety cables run through the center of extension springs to contain them if they snap. Torsion springs don't require them because they're enclosed in a shaft.
What should I do if my spring breaks while the door is open? Keep the door open. Do not try to close it manually. Call for emergency service right away. A broken spring means your opener cannot safely lower the door.
