Garage door springs are the hardest working part of your system. They counterbalance the weight of your door, making it easy to open and close. When one snaps, your door becomes dead weight. In Granby, we see failed springs year-round, and homeowners often wonder which type they have, how much replacement costs, and whether they can fix it themselves. The short answer: don't attempt this repair alone.
Two main spring styles handle garage doors: torsion and extension springs. Knowing which one you have matters for cost, safety, and repair timelines. See our guide on chain maintenance: a complete guide for homeowners.
Torsion springs sit horizontally above your door opening. They twist to store and release energy. One torsion spring can support an entire door. These springs last 7 to 9 years with normal use, depending on your climate and how often you open and close the door. When a torsion spring fails, the door won't budge.
Extension springs run vertically along each side of your door. Most residential doors have two extension springs working together. They stretch and contract as the door moves up and down. Because the workload splits between two springs, extension springs sometimes last a bit longer than torsion. However, when one snaps, you've lost half your spring power.

If you're unsure which type you have, look above your door. Horizontal bar? Torsion. Vertical springs on the sides? Extension. When you're ready to learn more about your complete system, our smart garage door technology article covers safety features that work alongside spring replacement.
Torsion spring replacement typically runs $150 to $300 per spring, depending on size and quality. Extension springs cost $100 to $200 each. Labor makes up most of the expense, not the parts. A professional needs special tools, knowledge of proper tension, and safety equipment. This isn't a weekend DIY project.

Many homeowners ask if we can install just one spring when both are the same age. Technically yes, but I don't recommend it. Springs age together. If one has failed, the other is close behind. Replacing both now saves you a second service call in weeks or months. It's more economical in the long run.
Same-day repair is possible if you call early. We keep common spring sizes in our trucks and can often complete replacement before dinner. Request an estimate by contacting us or calling to schedule a free quote.
A snapped spring releases enormous tension. Springs are under 200 to 500 pounds of force depending on door weight. Improper installation or adjustment can cause serious injury, property damage, or a door that crashes down unexpectedly.
We've treated customers in surrounding towns, including East Granby and Windsor, who tried DIY spring work and ended up with crushed fingers or worse. The cost of an emergency room visit far exceeds professional repair. Plus, an incorrectly installed spring voids most door opener warranties.

A garage door that feels heavy or jerky when opening suggests spring wear. Listen for creaking or popping sounds. If your door closes too fast or opens slowly, springs are losing strength. Some doors refuse to stay open or won't close all the way. These are all warning signs.
The most obvious sign: a loud bang followed by a door that won't open. That's a snapped spring. Don't force the opener. You'll damage the motor and track.
If you suspect spring trouble, stop using your door. Call us today at (860) 650-1814. We'll ask a few quick questions over the phone and often can schedule same-day service. For new customers, we always provide a free estimate before work begins.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal residential use (opening and closing 3 to 5 times daily). Extension springs may last slightly longer. Frequency of use, climate, and maintenance all affect lifespan. Harsh weather accelerates wear.
Can I replace just one spring? Technically yes, but both springs usually fail within months of each other since they age together. Replacing both at once prevents a second service call and saves money over time. Single spring replacement costs nearly the same as doing both.
How much does spring replacement cost near me? Torsion spring replacement runs $150 to $300 per spring. Extension springs cost $100 to $200 each. Labor represents most of the cost. Exact pricing depends on spring size, door weight, and local service availability.
What should I do if my spring snaps? Stop using your garage door immediately. Don't force the opener. Call a professional technician. A snapped spring leaves your door extremely heavy and dangerous. Avoid DIY repair due to high injury risk from spring tension.
