Garage Door Springs in Canterbury: When to Replace and What to Expect
August 24, 2026 4 min read
In our years serving Canterbury, we've seen this problem again and again: a homeowner opens their garage door one morning, hears a loud bang, and suddenly the door won't budge. Nine times out of ten, it's a snapped spring. Garage door springs in Canterbury fail for predictable reasons, and knowing what to expect saves you time, money, and frustration.
Why Springs Break (And When)
Torsion springs live under extreme tension. They counterbalance your door's weight so the opener can lift it smoothly. A typical residential spring lasts 7 to 9 years with normal use. That's roughly 10,000 to 15,000 cycles before the metal fatigues and snaps. See our guide on style matching tips: what every homeowner should know.
Extension springs, mounted above the horizontal tracks, work the same way but sit outside the door frame. Both types wear out at similar rates. Cold winters in New England accelerate failure because metal becomes brittle. Rust and lack of lubrication speed things up further.
When you hear that explosive crack, don't try to operate the door. A broken spring means the full weight of your door, often 300 to 500 pounds, rests entirely on the opener motor and cables. Forcing it risks injury and damage to other components. Read about panel repair: a complete guide for homeowners.
The Cost and Timeline for Replacement
A free estimate from Garage Door Canterbury typically reveals two paths: single spring replacement or both springs at once. Many homeowners replace just the broken one to save money upfront. We recommend replacing both, even if only one failed. Here's why: if one spring wore out, the other is close behind. Replacing both now prevents a second emergency call in six months.
Single spring replacement runs $150 to $300 in most Canterbury homes. Both springs together: $250 to $450. These figures include labor and the spring itself. Installation takes 1 to 2 hours for an experienced technician.

How Springs Work with Your Full Door System
Springs don't operate in isolation. They work alongside cables, pulleys, and your opener to create smooth operation. If you've recently had panel repair work done, check that your springs weren't overlooked during inspection. A technician should always test spring balance while addressing other issues.
The torsion rod runs through your springs at the top of the door opening. When springs snap, that rod can shift or tilt, throwing the entire system off balance. Misaligned springs force the door to bind or travel unevenly on the tracks. This puts stress on the opener and can damage cables next.
That's why preparing your garage door for spring weather includes a spring inspection. Temperature swings from winter to spring stress metal components. A quick tune-up catches weakening springs before they fail.
Getting Professional Help Near You
DIY spring replacement is not recommended. The tension stored in a compressed torsion spring can cause serious injury. A slip of the wrench, a momentary loss of focus, and the spring can unwind violently. Hospital visits for spring-related injuries are more common than most homeowners realize.
Our technicians carry the right tools, replacement springs in common sizes, and the experience to do it safely. We'll test the door balance after installation and adjust if needed. Schedule a free quote or call us to discuss your specific situation and get an estimate.
When Replacement Becomes Installation
Sometimes a snapped spring signals the need for a full door replacement. If your door is 15 years old, has multiple damaged panels, and now springs are failing, you're looking at compounding repair costs. In those cases, reviewing our installation guide helps you understand your options. A new door with fresh springs, cables, and hardware often costs less than repeated repairs.
Don't ignore a broken spring. The longer your door sits unused, the more it can rust, and the more expensive repairs become. Contact us today for a same-day estimate and professional service you can trust.
Frequently Asked Questions
How do I know if my spring is broken? The door won't open, or it opens but only a few inches before stopping. You may hear a loud popping or snapping sound. The door feels heavier than normal when trying to lift it manually.
Can I still use my garage door opener with a broken spring? No. Using the opener strains the motor and cables, risking further damage and potential injury. The door may fall unexpectedly.
Are extension springs safer than torsion springs? Both types are under high tension. Torsion springs are contained within a rod and generally considered safer for homes with children or pets present.
How often should springs be serviced? Springs need no regular service beyond occasional lubrication. However, an annual inspection catches rust and wear early, extending their life to the full 7 to 9 years.
What if only one spring is broken? We recommend replacing both. The second spring is equally worn and will likely fail within months, costing you another service call and downtime.
