Not all garage door springs do the same job, and picking the wrong one wastes money and invites trouble. The two main types in use today are torsion and extension springs. Each handles the weight differently, fails in different ways, and costs differently to replace. Understanding which one you have matters before you call for repairs.
Torsion springs wind up like a clock and release rotational force as your door opens. They sit horizontally above the door opening on a metal rod. When the door closes, tension builds inside the coil. When you open it, that stored energy unwinds smoothly, making the opener's job easier. Most modern homes built in the last 20 years use torsion springs because they're safer, quieter, and gentler on garage door openers.
Extension springs work the opposite way. They stretch along the sides of your door frame, one on each side. As the door closes, they get longer and store energy through tension. When you open the door, they contract and pull the door up. Older homes frequently have extension springs, and some lighter-duty doors still use them today. The tradeoff is that extension springs create more wear on the opener motor and are harder to balance.
If you're unsure which type you have, look above your door opening. A horizontal rod with a wound coil means torsion. Two springs running vertically along the frame means extension.
A snapped spring stops your door cold. With torsion springs, the door won't move at all because that single coil carried all the weight. With extension springs, you might get partial movement, but both sides need to fail before the door becomes completely stuck. When one extension spring breaks, the door pulls unevenly, straining the opener and creating a safety hazard.
This is why professional help matters. If you have a snapped spring in Loudon, attempting a DIY fix puts you at serious risk of injury. The springs carry hundreds of pounds of tension. A slip of the wrench or careless movement can cause the spring to snap again, the rod to whip, or your hand to get caught. We've seen too many homeowners learn this lesson the hard way.
Our team at Loudon Garage Doors handles both types with the proper tools and safety protocols. Schedule a same-day estimate for spring replacement if your door isn't moving smoothly or has stopped entirely.

Torsion springs typically cost more upfront than extension springs, but they last longer. Most torsion springs run 7 to 9 years before fatigue sets in. Extension springs wear out faster, usually in the 5 to 7 year range, because the constant stretching and contracting breaks down the metal quicker.
The actual cost of replacement depends on the spring type, door weight, and how many springs need replacing. A single torsion spring replacement costs less than replacing both extension springs, but torsion springs are heavier duty. If you're budgeting for repairs, expect torsion work to run higher than extension work per spring, though the longevity often justifies the investment.

Springs don't really repair. Once they're damaged, they need replacement. But knowing when damage is coming helps you avoid emergency calls at the worst times.
Our maintenance guide covers the tune-up that stops emergencies, including annual spring inspections. A tech can spot early signs of wear, rust, or loss of tension before the spring fails completely. Catching these issues saves you from being locked out of your garage or facing a costly emergency repair bill.
If you're hearing creaking, seeing the door move unevenly, or noticing the opener working harder than usual, springs are likely losing strength. Don't wait for a snap. Call us for a professional spring repair assessment and get ahead of the problem.
Springs require precise measurement, correct tension settings, and safety equipment. The rod must be centered, the springs balanced equally, and the door tested to open and close smoothly under its own weight. An off-balance setup wears the opener faster and creates uneven stress on the frame.
We take the time to get it right because a botched job comes back to haunt you within months. That's the craftsman approach: do the work once, do it properly, and your door works reliably for years.

How do I know if my garage door spring is about to break? Listen for creaking or squeaking when opening and closing. Watch for the door rising unevenly or stopping midway. These are early warning signs that spring tension is fading. Have a professional inspect it before it fails completely.
Can I open my garage door manually if a spring breaks? Torsion spring failure leaves the door stuck. Extension spring failure may allow partial manual opening, but it's unsafe and strains the door frame. Call a professional instead of forcing it.
How long does spring replacement take? Most replacements take 1 to 2 hours for a single spring, slightly longer if both need replacing or if the door frame needs adjustment. Same-day service is often available in Loudon.
Is one spring type better than the other? Torsion springs are safer, quieter, and last longer but cost more. Extension springs are cheaper upfront but wear faster. Most modern homes and newer doors use torsion. Your door's design usually determines which type you need.
What should I do if my spring snaps? Stop using the door immediately. Call a professional garage door technician. Do not attempt removal or replacement yourself. Spring tension can cause serious injury if mishandled.
