In our years serving Campton, we've seen this problem again and again: a homeowner steps into the garage one morning, hears a loud bang, and finds their door stuck halfway open. A snapped spring is usually the culprit. These metal coils carry all the weight of your door, and when they fail, nothing works until they're replaced. The good news is that knowing what to expect means fewer surprises and faster solutions.
Your garage door weighs between 300 and 500 pounds. It doesn't fall on your car or your head because two springs hold the tension and counterbalance that weight. Most residential doors in Campton use torsion springs, which wind tightly around a shaft above the door opening. When you open the door, springs gradually unwind. When you close it, they wind back up. This cycle repeats thousands of times over their lifespan.
Extension springs work differently. They're mounted on either side of the door and stretch under tension rather than twist. Both types fail eventually. Springs last roughly 7 to 9 years under normal use, though the exact timeline depends on how often you open and close your door. A door that opens and closes 4 to 8 times daily wears springs faster than one used twice daily.
Don't wait for a dramatic break. Catching a weakening spring early saves money and prevents being stuck with a non-functional door. Listen for squeaking or creaking sounds during opening and closing. If your door feels heavier than usual, struggles to rise smoothly, or only opens partway before reversing, a spring is likely losing tension. A door that won't stay open without the opener running is another red flag.
Inspect the springs visually if you feel comfortable doing so. Look for gaps, rust, or visible cracks. Never try to adjust or repair springs yourself. These components hold enormous tension and can cause serious injury. This is work for trained technicians only. If you're unsure whether your springs need attention, schedule a free quote with Garage Door Campton and let us assess the condition.
Torsion springs are the more common choice in modern Campton homes. They're mounted horizontally above the door and rotate as the door moves. They handle the weight more smoothly and last slightly longer than extension springs. When a torsion spring fails, it usually fails completely and suddenly. That's the loud bang you hear.
Extension springs hang vertically on each side of the door. They're less expensive upfront but typically wear out sooner. If an extension spring snaps, a safety cable running through it should catch the spring and prevent it from flying across your garage. Both types need professional replacement.

The cost depends on whether you need one spring or both, which type you have, and your door's size. A single torsion spring replacement typically runs between $150 and $300 in labor alone, plus parts. Extension springs are usually cheaper. Many technicians recommend replacing both springs at the same time, even if only one has failed. This prevents the second spring from breaking weeks later and costing you another service call.

Spring failure often accelerates when your door lacks basic maintenance. Rust eats away at metal. Debris builds up around the springs. Lack of lubrication increases friction. A regular maintenance routine catches problems early and can extend spring life by a year or more. Our maintenance guide covers the tune-up that stops repairs before they start, including spring care that most homeowners overlook.
If you live in Campton or nearby areas like Thornton, keeping your springs lubricated and your door balanced will reduce wear and give you better warning before failure happens.
A broken spring leaves your garage door inoperable. You can't park inside. You can't access stored items. If you have a detached garage, this is inconvenient. If your garage is attached to your home, it's a security issue. That's why we prioritize same-day spring replacement for customers in Campton. Most calls that come in before 2 p.m. can be handled the same day.
Call (978) 341-3619 to discuss your spring issue and get a same-day estimate if possible. The sooner you address a snapped spring, the sooner your life returns to normal.

How do I know if my garage door spring is broken? A loud bang or pop followed by the door stopping mid-cycle usually means a snapped spring. You may also notice the door won't open, feels much heavier, or opens only partially before reversing. Never force a stuck door.
Can I replace a garage door spring myself? No. Springs hold extreme tension and can cause serious injury or death if mishandled. Always hire a licensed technician. DIY attempts often result in hospital visits or worse.
How much does a garage door spring replacement cost? Single spring replacement typically ranges from $150 to $300 in labor plus parts. Replacing both springs at once costs more upfront but prevents a second failure weeks later. We'll provide an exact estimate after inspection.
How long do garage door springs last? Most springs last 7 to 9 years with normal use, roughly 10,000 cycles. Doors that open and close more frequently wear springs faster. Regular maintenance and lubrication can extend their lifespan slightly.
Why did my spring break without warning? Springs gradually lose tension over years of use. Rust, lack of lubrication, and extreme temperature swings in New Hampshire winters accelerate failure. A spring that seems fine one day can snap the next due to accumulated stress.
