A customer called last Tuesday morning saying her garage door wouldn't budge. No sound, no movement, nothing. Within five minutes of talking to her, I knew the answer: snapped spring. That's the most common reason a garage door goes from working fine to completely stuck overnight. Garage door springs in Cohasset fail silently, and when they do, you're looking at a service call and a repair estimate that catches most homeowners off guard.
Garage door springs operate under enormous tension. A typical residential door weighs 300 to 400 pounds, and the spring system balances that load so your opener doesn't have to. Each spring cycles roughly 10,000 to 15,000 times over its lifespan, which translates to about 7 to 9 years of normal use before failure becomes likely.
Torsion springs are the most common type in Cohasset homes. They twist and untwist to store and release energy. Extension springs work differently, stretching like a rubber band, but both types eventually wear out. Rust accelerates the process, especially near the coast where salt air corrodes metal. Temperature swings stress the metal too. When a spring finally gives, it happens fast. You hear a loud bang, and the door becomes a dead weight.
Most homeowners don't realize they can maintain spring life through regular lubrication. A simple coat of garage door lubricant once or twice a year reduces friction and extends durability. We cover that topic in detail in our garage door lubrication and maintenance guide, which walks through the right products and technique.
Here's where honesty matters. A typical torsion spring replacement in the Cohasset area runs between $200 and $400 per spring, including labor. Most doors have two springs, so you're looking at $400 to $800 total. Extension springs cost a bit less, usually $150 to $250 each. Labor time is roughly one to two hours for a technician who knows what they're doing.
The estimate includes the spring itself, hardware, and professional installation. Some shops bundle this into a flat rate. Others charge hourly. We always provide a transparent estimate before touching anything, because I've seen too many homeowners shocked by a bill after the work is done.

If both springs are old, replacing them together makes sense even if only one snapped. Springs fail in pairs, and if one is already nine years old, the other is close behind. Replacing both at once costs more upfront but saves you from a second service call in three months. That's practical math, not a sales pitch.
Don't try to limp along with a broken spring. Putting stress on your garage door opener when the springs aren't working will damage the opener motor. That escalates repair cost from $500 to $1,500 or more. Your door also becomes a safety hazard because it can fall suddenly if the opener isn't holding it up.
If you're in an emergency and can't open the door to get your car out, we offer emergency garage door service in Cohasset. We typically respond same-day for urgent calls. For less critical repairs, we book within 48 hours.
The best defense is maintenance. Inspect your springs twice a year for visible wear, rust, or fraying. Listen for unusual sounds when the door operates. A creaking or grinding noise signals friction that lubrication can fix before it becomes a break.
We offer a full maintenance program through our services page, which includes spring inspection, lubrication, and hardware checks. Preventive care costs far less than emergency repairs.

Look for rust spots, visible cracks, or a gap between coils. Listen for creaking or popping sounds during operation. If one spring is more than eight years old, have both inspected soon. A technician can assess wear and predict failure.
Springs operate under extreme tension and can cause serious injury or death if mishandled. Professional replacement is strongly recommended. Even experienced DIYers should hire a technician for this job.
Torsion springs twist above the door and are more durable and safe. Extension springs hang on the sides and stretch. Torsion springs last longer and handle weight better, though both types eventually wear out.
Springs are paired and share the load equally. If one breaks, the other was already stressed. That's why we recommend replacing both springs at the same time, even if only one snapped.
A typical single torsion spring replacement runs $200 to $400 including labor. Two springs cost $400 to $800. A free estimate clarifies your exact situation before work begins.
