A customer called last Tuesday morning. Her garage door wouldn't open. When we arrived, the culprit was clear: a snapped torsion spring hanging limp above the door. She'd heard a loud bang the night before but thought it was just wind. Springs fail without warning, and when they do, your garage door becomes a dead weight. This is the most common emergency we handle in North Hampton, and it's also entirely preventable with the right knowledge.
Your garage door weighs 300 to 400 pounds. Two springs, working in tandem, counterbalance that weight so your opener can lift the door smoothly. Springs live under constant tension. Every time you open or close the door, they flex. Over 7 to 9 years, metal fatigues. It cracks. It fails.
There are two types: torsion springs (mounted horizontally above the door) and extension springs (mounted on the sides). Torsion springs are stronger and last longer, but when they snap, the failure is sudden and dramatic. Extension springs are gentler when they fail, but they wear faster. Both types experience the same root causes: rust, friction, lack of lubrication, and simple metal fatigue.
North Hampton sits near the coast, which means salt air accelerates corrosion. We've seen springs fail years earlier than they would inland because salt water eats into the metal. Temperature swings in New Hampshire winters also stress the metal. Cold makes steel brittle. It contracts. Spring failure is 40 percent more common in winter than summer around here.
Many homeowners assume a snapped spring costs $100 or $200 to fix. That's not how it works. Springs come in pairs, and they should be replaced together. If one fails, the other is close behind. Replacing both springs typically costs between $250 and $400, depending on the type and quality.
The real expense isn't always the parts. It's the labor and the inconvenience. A same-day service call costs more than scheduling work a week out, but when your garage door is stuck and your car is parked inside, that premium feels worth every penny.

Professional installation matters too. A botched spring replacement can leave your door unbalanced, which strains the opener and damages the door itself. We've seen DIY attempts end in costlier repairs. Springs are under 200 pounds of pressure per spring. A mistake can cause injury.

The smartest investment is regular maintenance. Every few months, apply lubricant to your springs and hinges. Lubrication reduces friction and extends spring life by years. We've written a complete guide on garage door lubrication and maintenance that covers the specifics.
Spring inspection should happen during your annual garage door tune-up. Look for visible wear, rust, or uneven gaps between coils. If a spring shows signs of corrosion or one coil is slightly separated from the others, that's a warning sign. Call us before the spring snaps rather than after.
Budget-conscious homeowners often ask: should I replace springs before they fail? If a spring is 8 years old and showing rust, yes. The cost of preventive replacement is less than an emergency call plus the hassle of a stuck door. If your door is still running smoothly and springs look clean, wait. But have a plan for when failure happens.

Never attempt to replace garage door springs yourself. Springs are dangerous. The tension can cause serious injury. A professional has the tools, experience, and liability insurance to do the job safely.
When your spring fails, your garage door won't open or close reliably. Some doors will drop suddenly. Others won't move at all. This is a safety hazard and a security risk. Our team handles spring replacement on residential and commercial doors. We can typically complete the work and balance the door the same day you call.

Spring failure isn't a matter of if, but when. When it happens, you want someone who knows the work. We do this the right way, every time.
How do I know if my garage door spring is about to break? Listen for unusual noises during operation. Look for gaps or separation between coils, visible rust, or an unbalanced door that pulls to one side. If the door moves slowly or feels heavy, a spring is weakening.
Can I use my garage door if one spring is broken? No. A broken spring removes half the counterbalance. The door becomes dangerously heavy and unstable. Operating it risks injury and damage to the opener and door.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Coastal salt air and harsh winters reduce these timelines by 1 to 2 years.
What's the difference between torsion and extension springs? Torsion springs are mounted horizontally above the door and twist to lift it. Extension springs are mounted on the sides and stretch. Torsion springs are stronger and safer but more expensive to replace.
Do I need both springs replaced at once? Yes. Springs wear at the same rate. Replacing only one leaves the other at imminent risk of failure. Professional replacement includes both springs, which costs less than two separate service calls.
