If you've ever dealt with a stuck garage door, you know how frustrating it can be. Nine times out of ten, the culprit is a broken spring. Springs are the hardest working part of your system, and they don't last forever. Most residential garage door springs last 7 to 9 years with normal use. This post covers the warning signs, repair versus replacement decisions, and honest pricing so you know what to expect before you call.
Your garage door weighs between 300 and 700 pounds, depending on the material and size. Two types of springs do the heavy lifting: torsion springs and extension springs.
Torsion springs sit horizontally above your door and twist to store and release energy. They're the most common choice in modern homes and typically last longer than extension springs. Extension springs run along the sides of your door and stretch like a rubber band. Both systems use the same principle: they counterbalance the door's weight so your opener doesn't have to do all the work.
When a spring snaps, your door becomes effectively a dead weight. Your opener can't lift it safely. That's when homeowners realize just how important these small metal coils really are.
Don't wait for a complete failure. A few warning signs show up before the break.
Listen for a loud bang or crack from the garage. That's usually the sound of a spring snapping under tension. If your door opens or closes unevenly, one spring may already be weakened. The door might sag on one side or move jerkily instead of smoothly. Some doors slow down as they open or close. Others won't budge at all, even though your opener is running.
If you notice any of these issues, stop using your door immediately. A partially broken spring can snap completely without warning, and that sudden release of tension is dangerous. For a closer look at how your door should behave, check our guide to troubleshooting a broken or stuck door.
Extension springs are cheaper to replace, typically running $150 to $250 per spring. Torsion springs cost more, usually $200 to $400 per spring, but they're more durable and safer overall.
Here's the honest part: once a spring snaps, repair isn't really an option. Springs don't get "fixed" back to original strength. You replace them. Both springs should be replaced at the same time, even if only one broke. They work as a pair, and installing just one new spring creates an imbalance that wears out the remaining old spring faster.
The cost to replace both torsion springs typically runs $400 to $800 installed, depending on your door's weight and your local market. Extension springs run $300 to $500 for both. Get an honest estimate that includes labor and any adjustments your door needs.

Springs are under extreme tension. A snapped spring or a spring that releases unexpectedly can cause serious injury. Fingers, hands, and faces have been permanently damaged by DIY spring work. We strongly recommend hiring a professional for any spring replacement or repair.
A trained technician has the right tools, safety equipment, and experience to handle the job safely. Same-day service is often available in Cotuit and nearby areas. The cost difference between DIY and professional work is small compared to the risk.
A typical spring replacement project breaks down like this. The springs themselves run $150 to $400 each. Labor adds $200 to $400. Some jobs require new hardware or door adjustment, adding another $50 to $150. An honest estimate should give you a clear line-item breakdown before work starts.
Don't be surprised if a technician recommends replacing other components while they're in the garage. Worn cables, damaged tracks, or loose brackets should be addressed during spring replacement to avoid future problems. Ask for specifics on what's needed and why.
If your door is over 20 years old and the springs break, consider replacement instead of repair. An older door with worn hinges and weathered panels might cost more to maintain than to replace. Compare the cost of new springs plus repairs against a new door with a fresh warranty and modern safety features like photo eye sensors.
Newer doors are quieter, more energy efficient, and safer. If you're on the fence, schedule a free quote and we'll walk you through both options.
How long do garage door springs last? Most residential springs last 7 to 9 years with normal use. This assumes your door opens and closes about four times daily. Doors that cycle more frequently wear springs faster. Climate and maintenance also play a role.
Can I use my garage door if one spring is broken? No. A broken spring creates a dangerous imbalance. Your opener can't lift the door safely, and it could fall or hang unevenly. Stop using the door until the spring is replaced.
Why do both springs need to be replaced together? Springs work as a matched pair to balance the door's weight evenly. Replacing only one creates an imbalance that wears the remaining spring out much faster. Replacing both at once ensures even wear and longer service life.
What's the difference between a torsion and extension spring? Torsion springs twist above the door and are more durable. Extension springs stretch along the sides and are cheaper but wear out faster. Torsion is the safer, more common choice for residential doors.
How much does spring replacement cost in Cotuit? A typical torsion spring replacement runs $400 to $800 for both springs and labor. Extension springs cost $300 to $500 installed. Call (508) 690-5801 for a same-day estimate specific to your door.
