Snapped Garage Door Springs in Candia: Signs, Costs & Same-Day Fixes
2026-07-17 7 min read
A snapped garage door spring is one of the most common emergencies we handle in Candia, and it happens without warning. You'll hear a loud bang, then your door won't budge. Springs fail because they're under constant tension, pulling and pushing thousands of times per year until metal fatigue wins. We've seen homeowners try to manually lift a door with a broken spring, risking serious injury. Let's cut through the confusion about what happens next, why it costs what it does, and how to get moving again safely.
How Springs Work (And Why They Fail)
Your garage door weighs 300 to 500 pounds depending on size and material. Springs counterbalance that weight so the opener doesn't have to lift the entire load. Most residential doors use one of two types: torsion springs (one or two springs wound around a shaft above the door) or extension springs (mounted on either side, stretching as the door opens).
Torsion springs are the industry standard in Candia and the surrounding region. They're more durable and safer, but when one snaps, it's a complete system failure. Extension springs sometimes break one at a time, which means your door tilts unevenly, but it might still operate.
Springs last 7 to 9 years on average with normal use, maybe longer if you run the door 4 or 5 times daily instead of 10 to 15. Humidity, temperature swings, salt air exposure, and rust all accelerate wear. Cold New Hampshire winters actually compound the problem because metal becomes more brittle when temperatures drop.
Warning Signs Before Catastrophic Failure
Not every broken spring happens without notice. Listen for these red flags:
A grinding or squeaking noise when the door opens suggests springs are under uneven stress. The door moving slower than usual means springs are losing strength. Visible rust or corrosion on the spring assembly is a clear signal that failure is coming soon, not someday.
If you notice the door sagging slightly when closed, or if it's harder to open manually (using the emergency release), springs are probably near the end of their life. Don't wait for the bang. A preventive replacement costs far less than an emergency call plus a tow truck if you're stranded away from home.

What Happens When a Spring Snaps
The moment a torsion spring breaks, the door's weight transfers entirely to the opener motor. The door either won't move at all, or it will close partially and get stuck. Trying to force it open with the wall button will burn out the motor and void the warranty.
Extension springs sometimes allow limited movement because the other spring may still be functioning, but the door will be dangerously unbalanced. Never attempt a manual lift. Even a 400-pound door can fall fast and cause crushing injuries to hands, arms, or worse. The safety features we covered in our auto-reverse and photo eye guide won't help if a spring has snapped because the door is already in a failure state.
Repair Cost and Timeline for Candia Residents
A single torsion spring replacement typically runs $200 to $400 including labor and the spring itself. If both springs are original and old, replacing both at once costs $350 to $600. Extension springs are slightly cheaper per unit but labor is similar.
We offer same-day estimates and emergency scheduling because we know this isn't convenient. If you're in Candia or nearby towns like Hooksett or Raymond, we can usually dispatch a technician within a few hours. For detailed pricing context and what affects total cost, our emergency repair cost breakdown walks you through the variables.
Parts and labor make up the bulk of the bill, but quality matters. Cheap aftermarket springs fail faster and void opener warranties. We install springs rated for your specific door weight and use hardware that matches manufacturer specs.
DIY Isn't Safe Here
Spring replacement involves dangerous tension and requires specialized tools. A wound spring can store enough energy to cause serious injury if it unwinds unexpectedly. We've treated customers who tried to save money and ended up in the emergency room. This is one repair where professional service isn't optional, it's survival.
Our team at Garage Door Candia handles spring replacement as a core service. We'll inspect the rest of your door system while we're here, check the opener, and make sure everything else is aligned and functioning properly.

Frequently Asked Questions
How do I know if my spring is snapped or just loose? A snapped spring usually produces an audible bang and the door won't move at all. A loose spring might let the door move unevenly or slowly. Either way, don't try to operate the door yourself. Call a professional to inspect it safely.
Can I use my garage door opener if one spring is broken? No. Operating the opener with a broken spring will damage the motor and likely cause the door to fall, creating a safety hazard. Leave the door closed and call for repair.
Why are my springs rusting so fast in Candia? New England humidity, road salt, and temperature fluctuations accelerate corrosion. Annual lubrication and occasional inspection slow rust formation and extend spring life by 1 to 2 years.
What's the difference between torsion and extension springs? Torsion springs are safer, last longer, and handle heavy doors better. Extension springs are cheaper upfront but more prone to failure and less controlled when they break. Most modern doors use torsion.
Should I replace springs if one breaks, or just the broken one? If both springs are the same age and either is over 7 years old, replace both. Replacing one while the other is near failure means you'll pay for another service call in months.
