Here's what most homeowners don't realize about garage door springs: you probably can't name the type holding up your 400-pound door right now. That gap in knowledge costs money. When a snapped spring catches you off guard, you'll either overpay for the wrong replacement or waste time finding someone who knows the difference. Andover homeowners who understand torsion versus extension springs avoid both traps and get faster, cheaper repairs.
Your garage door uses one of two systems. Torsion springs wind around a metal rod above the door opening. They twist to store and release energy as your door moves up and down. Extension springs hang on either side of the door track. They stretch and contract like a rubber band, pulling the door upward through a pulley system. See our guide on garage door installation in andover: what to expect, real costs & how to choose.
The type you have matters for three reasons: cost, safety, and replacement complexity. Torsion springs typically run $150 to $300 per pair, while extension springs cost $75 to $150 per pair. But torsion systems are safer because they contain the spring's force if failure occurs. An extension spring that snaps can whip across your garage with serious injury risk. That's why many newer homes and commercial buildings use torsion exclusively.
Walk into your garage and look directly above the door. If you see a long metal rod running horizontally with a spring coiled around it, you have a torsion system. The spring looks like a cylinder sitting on top of the door frame. If instead you see two springs attached to cables on either side of the door opening, stretching vertically along the tracks, those are extension springs.

Extension springs are easier to spot when they fail. A snapped extension spring leaves one side of your door sagging or stuck. The broken spring hangs loose like a deflated spring. Torsion springs fail more quietly but completely. Your door won't budge because the spring stored all the lifting power. Either way, a snapped spring means no DIY fix. Andover garage doors are heavy. Replacing a spring without professional equipment risks crushing your hand or worse.
Both spring types last roughly 7 to 9 years with normal use. That means if your door is 8 years old and one spring fails, the other is likely near failure too. Many homeowners save money by replacing both springs at the same time rather than paying for a second service call a few months later.
If you need same-day service, torsion spring replacement typically takes 1 to 2 hours. Extension spring work is faster, often 45 minutes to an hour. However, labor rates don't change much between systems. You're paying for the technician's expertise and equipment, not just the spring itself. Get an estimate before committing. Our team at Andover Garage Doors provides free estimates and can often schedule same-day appointments.

Understanding your spring type helps you plan maintenance. Torsion springs need regular lubrication to prevent rust and extend their lifespan. Extension springs require cable inspection because if a cable snaps alongside the spring, your door could fall. Both systems benefit from a professional tune-up every 2 to 3 years.
If you're planning a garage door replacement, knowing your current spring system helps contractors give accurate pricing. Some homeowners upgrade from extension to torsion specifically for safety. Others stick with what works. Either choice is fine if it's informed. Learn more about spring replacement costs and real pricing in our detailed guide on garage door springs in Andover.
When a spring fails, don't panic. Contact a licensed technician for diagnosis. You can schedule a free quote or ask about same-day estimates to get your door working again without guesswork.
Your next step is simple: identify your spring type, document when it was last serviced, and call for a professional inspection if you hear unusual noises or notice your door moving slowly. Most spring failures are preventable with basic maintenance.
Can I replace just one spring if only one snapped? Technically yes, but both springs wear equally. Replacing only one means the other fails soon after, costing you another service call. Most professionals recommend replacing both springs together for reliability and cost savings over time.
How much does a snapped spring replacement cost in Andover? Torsion spring replacement runs $300 to $600 total (parts plus labor). Extension springs cost $200 to $400. Prices vary by contractor and whether you need emergency same-day service, which may add fees.
Is a snapped spring ever a DIY fix? No. Springs under extreme tension can cause serious injury or death if mishandled. Always hire a licensed technician with proper tools and insurance coverage.
How do I know if my spring is about to fail? Listen for loud creaking or popping sounds during operation. Your door may move slower than usual or feel heavier to open manually. These are warning signs to call a professional for inspection.
Do I need to replace springs if I'm getting a new garage door? Sometimes. If your new door matches your old door's weight and size, old springs may work. If you're upgrading to a heavier insulated door, new springs are required for safe operation and warranty coverage.
