After 15 years turning wrenches on garage doors across Nottingham and southern New Hampshire, I've learned that most homeowners don't know the first thing about the springs holding their doors up. That's not a dig. Springs live above your head, hidden and quiet, until they snap. Then you've got a 400-pound slab of steel hanging by a cable. Let's cut through the confusion about garage door springs and give you the straight facts.
Your garage door weighs between 300 and 500 pounds depending on size and material. That weight doesn't stay suspended by magic. Springs do the work. Two main types handle this job: torsion springs and extension springs. Torsion springs wind up like a clock and unwind as your opener lifts the door. Extension springs sit on either side of the door and stretch as it closes, then contract to help it open. Both types work with your opener to make the lift feel smooth and effortless.
Springs last roughly 7 to 9 years under normal use. That's not a guarantee. Salt air near the coast, extreme temperature swings in winter, and heavy use all shorten that timeline. A snapped spring doesn't just inconvenience you. It puts strain on your opener, the cables, and the tracks. Ignore a broken spring, and you're looking at a much bigger repair bill.
Torsion springs mount horizontally above your door opening. They twist and unwind thousands of times over their lifespan. If you've heard a loud bang from your garage, that was likely a torsion spring reaching the end of its life. These springs are safer than extension springs because they're enclosed and tensioned differently. When they fail, they're more predictable.
Extension springs run along the sides of your door tracks. They work like a rubber band, stretching as the door lowers and pulling back as it rises. They're cheaper to replace than torsion springs, but they require safety cables to catch them if they snap. That cable runs through the center of the spring. Without it, a snapped extension spring becomes a dangerous projectile.
Here's what matters for your wallet: torsion springs cost more to replace. You're paying for the part itself, the labor to remove and wind the new spring safely, and the specialized tools we need to do it right. Extension springs are cheaper parts, but installation isn't a DIY job either. Improper tensioning can damage your opener or worse.

A sagging door is the most obvious sign. If your door doesn't open all the way or closes unevenly, one spring is likely weakening. You might hear creaking or groaning noises during operation. Sometimes the door moves slowly or feels heavier than usual. These are all red flags.
Don't wait for a spring to snap completely. A broken spring leaves you with a jammed door and no easy way to open it. If you notice any of these warning signs, get a same-day estimate from our team rather than risk an emergency repair later.

Pricing varies based on the spring type and your door's size. Extension springs typically run between $150 and $300 per spring, including labor. Torsion springs range from $250 to $600 or more. If both springs need replacement (and often they do, since they age together), double those numbers.
Emergency calls outside business hours add a surcharge. Same-day service is possible if you call early. The best way to know the exact cost for your door is a free estimate. We'll inspect the springs, check your opener and cables, and quote the work without pressure.

This is important. Garage door springs are load-bearing parts that wear at similar rates. If one spring has failed, the other isn't far behind. Replacing only the broken spring leaves you with mismatched wear and tension. Your door won't operate evenly. Within months, the second spring fails. You'll pay for labor twice.
Our technicians always recommend replacing both springs together. Yes, it costs more upfront. It saves you money and hassle over the life of your door. Learn more about our spring replacement services to understand the full picture.
I say this with respect: don't try this yourself. Springs are under enormous tension. A slip with the wrong tool, a miscalculation with the winding bars, and you could break bones or worse. We've had homeowners call after hurting themselves attempting a DIY fix. The cost of a hospital visit dwarfs the price of professional service.
We have the right tools, the training, and the liability insurance to do this safely. That's worth every penny.
How do I know if my garage door spring is broken? A loud bang or crack from your garage is the most common sign. Your door may hang unevenly, open slowly, or not open fully. If the door feels heavier than normal or creaks loudly during operation, a spring is likely failing.
Can I open my garage door if a spring is broken? Not safely. A snapped spring removes support from your door. Your opener has to work much harder and may overheat or burn out. You risk the door falling or jamming mid-operation, trapping your car or causing injury.
How often do garage door springs need to be replaced? Most springs last 7 to 9 years with normal use. Heavy use, salty air, and temperature extremes shorten that lifespan. A professional inspection every few years helps catch wear before failure.
What's the difference between a torsion and extension spring? Torsion springs twist horizontally above your door and are safer when they fail. Extension springs stretch along the sides of your tracks and are cheaper but require safety cables. Torsion springs cost more to replace.
Is spring replacement an emergency repair? It becomes one if the spring is completely snapped. A weakening spring that's losing power isn't urgent but should be addressed soon. Call us for an estimate, and we'll help you prioritize based on your door's condition.
