In our 15 years serving Medway, we've seen this problem again and again: a homeowner's garage door suddenly won't open, and they discover a snapped spring. Garage door springs typically last 7 to 9 years with normal use, but that lifespan depends heavily on cycle count, climate, and maintenance. A typical spring supports roughly 10,000 to 15,000 cycles before failure. If your door opens and closes daily, you're looking at the shorter end of that window. The good news? Knowing when springs fail and what to expect cost-wise keeps you prepared.
Two main spring styles power garage doors: torsion and extension springs. Torsion springs sit above the door and wind tightly to lift the weight. Extension springs hang on either side and stretch as the door opens. Most modern homes in Medway use torsion systems because they're safer and more durable. Extension springs can snap and whip dangerously if the cable breaks.
The type you have affects both lifespan and replacement cost. Torsion springs handle stress more evenly, which is why many homeowners prefer them long-term. Extension springs wear faster because they rely on constant stretching and contracting. Either way, both systems need professional attention when they fail. A snapped spring isn't a DIY fix.
Springs don't last forever. Metal fatigues over time, especially in New England winters when temperatures swing from below freezing to mild within hours. That thermal stress compounds the mechanical wear from daily use. Rust accelerates failure too. If you notice your door opening slowly, sagging to one side, or refusing to budge, a failed spring is likely the culprit.
You might also hear a loud bang or crack from the garage. That's the spring snapping under load. Never ignore that sound. A broken spring leaves your door heavier and potentially dangerous. The opener will strain harder trying to lift a one-tonne door with one working spring or none at all, which can damage the motor itself. We've replaced plenty of openers that burned out because homeowners delayed spring replacement.

A single torsion spring typically costs $150 to $300 installed, depending on quality and your door's weight. Extension springs run $100 to $200 per spring. Most doors need two springs, so budget $300 to $600 for a complete replacement. That estimate assumes no additional damage to cables or hardware.
Several factors push the cost higher. Heavy commercial doors or custom residential doors may need premium springs rated for extra cycles. If cables are damaged during the spring failure, those need replacement too. Older doors sometimes require hard-to-find spring sizes, which raises the price. That's why getting an accurate estimate from a local technician matters. When you call us for a same-day estimate, we inspect the whole system, not just the springs.

You can't stop springs from aging, but you can slow the process. Regular lubrication reduces friction and rust. Once a year, spray the springs and cables with a silicone-based lubricant. Keep the garage reasonably dry, especially during our humid Massachusetts summers. If you notice rust forming on the springs, address it early before it weakens the metal.
Another smart move: don't ignore small signs of wear. If one spring fails, the other is usually close behind. Most professionals, including our team at Garage Door Medway, recommend replacing both springs at the same time, even if only one has snapped. That prevents a second failure weeks later and saves labor costs overall.

How do I know if my garage door spring is broken? Your door won't open, opens very slowly, or tilts to one side. You may hear a loud bang or snap. Never force the door. Call a professional immediately. A broken spring leaves the door unsafe to use.
Can I use my garage door with a broken spring? No. The door is too heavy to lift safely without springs. Forcing the opener will burn out the motor, adding $300-$600 to your total repair bill.
How often should garage door springs be replaced? Typically every 7 to 9 years with normal daily use. Cycle count matters more than calendar time. High-use doors fail faster. We assess lifespan during every inspection.
Are torsion or extension springs better? Torsion springs last longer and are safer. They're standard in modern homes. Extension springs are older, wear faster, and can whip dangerously if cables break. Torsion is the better choice.
What's the total cost to replace both springs? Expect $300 to $600 installed for two springs on a standard residential door. Premium springs, heavy doors, or cable damage will increase the price. Always get a written estimate before work starts.
