How to Tell if Your Garage Door Spring Is Broken in Wentworth, NH
2026-07-05 8 min read A2Z Garage Doors
A customer called last Tuesday morning. His door wouldn't budge. He'd assumed the opener was dead until I walked him through a quick test: try lifting the door manually with the opener unplugged. It shot up effortlessly. The problem wasn't the opener. One of his torsion springs had failed silently overnight. That's the reality of garage door springs in Wentworth, NH. They fail without warning, and knowing the signs before they snap saves you money, frustration, and a stuck car.
The Most Obvious Sign: Your Door Won't Open (Or Won't Stay Up)
If your garage door opener runs but the door doesn't budge, a snapped spring is usually the culprit. The opener motor can't overcome the weight of the door alone. A healthy spring carries roughly half the door's weight. Without it, you've got a 400-pound barrier that your opener was never designed to lift by itself.
Manual testing confirms this instantly. Unplug the opener and try lifting the door by hand from the inside. A working spring makes it feel light. A broken one feels impossibly heavy, like lifting a car. If it won't budge at all or slams shut suddenly, stop. Don't force it. A falling garage door can cause real injury.
Secondary Clues That Point to Spring Failure
Not every broken spring stops your door cold. Sometimes you'll notice subtler signs first:
Loud bang or crash at night. A torsion spring snapping under tension makes a sound like a gunshot. Many Wentworth homeowners hear it and assume something hit the garage. It's usually just the spring giving up.
Visible gap in the spring coil. Pop the garage door open manually and look at the springs mounted above the door on the header. A healthy torsion spring looks like a tight, continuous spiral. A broken one has a visible gap where it snapped. That gap is your diagnosis.
Door sits crooked or uneven. If you have two springs and one fails, the door may tilt when opening or closing. One side rises faster than the other. This imbalance stresses the remaining spring and the opener. It's a sign to act fast.
Door feels heavier than normal. You notice this especially when using the manual release handle during a power outage. The door suddenly weighs more because the spring isn't sharing the load anymore.
Why DIY Repair Isn't Worth the Risk
Springs are under extreme tension. A torsion spring can store enough energy to snap a wrist or worse if you try to adjust or replace it yourself. I've been doing this work for years, and I still respect that tension every single time. The cost of a same-day professional repair is far cheaper than an ER visit.

Extension Springs vs. Torsion Springs
Not all springs fail the same way. Extension springs run horizontally along the sides of your door and stretch to absorb weight. Torsion springs are mounted above the door and twist. Both can snap, but torsion springs are more common in newer homes and carry more energy when they fail. Knowing which type you have helps you describe the problem accurately when you call for an estimate.
What Happens Next: Getting Your Door Working Again
Call a professional immediately. We'll perform a free visual inspection, identify whether it's truly the spring, and give you a honest estimate. No hidden fees. No upselling. Springs last about 7 to 9 years depending on use. If yours is older than that, replacement makes sense. If it's newer, a single repair might be all you need.
Our team at Wentworth Garage Doors handles same-day emergency calls. We keep common spring sizes in our trucks so you're not waiting days for parts. Schedule a free quote or call us directly.
Prevention Saves Money
Regular maintenance catches worn springs before they snap. Annual inspections catch rust, fraying, or loss of tension early. We can spot a spring nearing the end of its life and schedule replacement on your timeline instead of in an emergency. Check out our preventive maintenance schedule for a full breakdown.
If your door suddenly feels heavy, won't open, or you heard a loud bang, don't wait. A broken spring only gets worse and can damage your opener and door panels. Get a same-day estimate from our team or call 1-978-440-2999 now. We'll get you back on the road fast and explain exactly what went wrong.

Frequently Asked Questions
How much does it cost to replace a garage door spring in Wentworth? A single torsion spring replacement typically runs $150 to $300, depending on the spring size and door weight. Extension springs cost slightly less. Labor and parts together usually land between $200 and $400 for most residential doors. We always provide a written estimate before starting work.
Can I replace just one spring if I have two? Technically yes, but replacing both springs at once is smarter. If one has failed, the other is usually close behind. Replacing both costs more upfront but avoids a second service call in a few months when the second spring fails.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years, or about 10,000 to 15,000 cycles of opening and closing. Heavy daily use shortens that lifespan. Annual maintenance and lubrication can extend it slightly.
Is a broken spring an emergency? Yes. Your door won't open safely, and attempting to force it risks injury or damage to the opener and panels. Call for same-day service rather than trying workarounds.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are mounted horizontally. Extension springs stretch horizontally along the sides of the door. Torsion springs are stronger and safer, which is why most newer homes use them.
