Your garage door weighs 300 to 500 pounds. Springs do the heavy lifting, not your opener. Two main types exist: torsion and extension. Knowing which one you have prevents confusion, bad DIY decisions, and wasted money when something goes wrong.
Springs counterbalance your door's weight. Without them, your opener would burn out in weeks. They're not decorative. They're structural. See our guide on smart garage door technology in salem, nh: what you need to know.
Your door has either one torsion spring or two extension springs (occasionally both). Torsion springs sit horizontally above the door, twisting to store and release energy. Extension springs hang vertically on each side, stretching like rubber bands.
Most homes built in the last 20 years use torsion springs. They're safer, quieter, and last longer. Older Salem, NH homes often have extension springs. Both work. One just needs different handling. Read about garage door cost & pricing in salem, nh: what you.
Torsion springs twist around a shaft. Think of a clock spring, but bigger and stronger. A single spring handles all the work, or two springs share the load on larger doors.
Here's what matters: torsion springs last 7 to 9 years with normal use (roughly 10,000 cycles). When one breaks, the door stops moving. Period. No garage in or out.
The upside? Torsion springs store energy efficiently. Your opener uses less power. The door moves smoothly. Repairs cost slightly more, but you won't replace them as often.
When your torsion spring snaps, you'll hear a loud bang. Some people think their door exploded. It hasn't. But you do need a professional right away. Never attempt to replace or adjust torsion springs yourself. The tension is severe enough to cause serious injury.
Extension springs work like a garage door's shock absorbers. They hang on each side and stretch when the door lowers. When you open the door, they contract and help push it up.
Extension springs typically last 5 to 7 years. They fail more often than torsion springs because each spring does half the work, and wear distributes unevenly.
A broken extension spring is less immediately dramatic than a snapped torsion spring. The door might still move, but unevenly. You'll notice it tilting or grinding. The opener works harder and fails sooner.
Many older Salem homes have extension springs. If you own one, plan for more frequent replacement cycles. It's just part of the equation.
A snapped spring isn't a "call them when you get around to it" problem. Your door's safety cables and pulleys take the weight. They'll last maybe a week under full stress before failing. A falling door causes property damage and serious injury.
If your spring breaks, read our guide on staying safe after a snapped spring. Then call Salem Garage Doors or another licensed pro for same-day service.

Understanding garage door spring costs helps you budget. A torsion spring replacement runs $200 to $400, including labor. Extension springs cost $150 to $300. Prices vary based on door size, spring quality, and whether you need one or both springs replaced.
Never replace just one spring on a paired system. The new spring won't match the old one's wear and tension. You'll have an imbalanced door and another failure within months.

Some repairs belong at home. Spring replacement isn't one. Torsion springs carry 400 to 500 pounds of tension. A release mishap sends metal flying. Extension springs can snap unexpectedly under load.
Licensed technicians have tools you don't own. They've seen every failure pattern. They know Salem's climate and how it affects springs (salt air and freeze-thaw cycles are rough). Learn when repair versus replacement makes sense.
You can handle basic maintenance: keeping the door clean, lubricating hinges, and checking cables visually. Springs? That's professional territory.
Knowing the difference between torsion and extension springs puts you ahead. You won't panic if something breaks. You'll know what to expect cost-wise. You'll understand why a pro is necessary.
If your spring is broken or nearing the end of its life cycle, don't wait. A failure at the wrong moment leaves you unable to access your garage or worse. Contact Salem Garage Doors for an honest quote and transparent pricing. We serve Salem and the surrounding area with upfront estimates and no hidden fees.
How do I know if my spring is about to fail? Listen for creaking or squeaking. The door moves slower than normal or tilts to one side. Springs near failure show visible gaps or reduced tension. If you spot these signs, get an estimate before failure happens.
Can I replace one spring instead of both? No. If one spring breaks, the other is near failure. Replacing one leaves you with mismatched tension and a second failure within weeks. Replace pairs together for safety and smooth operation.
How often should garage door springs be replaced? Torsion springs last 7 to 9 years under normal use. Extension springs last 5 to 7 years. Frequency depends on how often you open and close your door.
What's the difference between a torsion and extension spring repair? Torsion springs need specialized tools and training. Extension springs are slightly simpler but equally dangerous. Both require professional service. Never DIY either one.
Is spring replacement an emergency? Yes. A broken spring makes your door unsafe and immobile within days. Get a professional assessment immediately to avoid injury or further damage.
