Garage door springs in Groton fail without warning, and when they do, your 400-pound door becomes a safety hazard. I've seen garage doors drop on cars, crush fingers, and trap children. These aren't rare accidents. Springs typically last 7 to 9 years, and most homeowners don't know they're on borrowed time until a loud BANG echoes through the garage at 6 a.m.
This post cuts through the confusion about torsion and extension springs, shows you exactly what failure looks like, and explains why calling a professional isn't optional.
Your garage door weighs between 300 and 500 pounds. Two springs counterbalance that weight so your opener doesn't burn out lifting the entire load. Without them, the motor would fail within months.
Torsion springs sit above the door and twist to store and release energy. Extension springs run along the sides and stretch. Both types endure roughly 10,000 to 20,000 cycles (open/close cycles) before the metal fatigues and snaps.
Rust, weather, and constant stress accelerate failure. In Groton, where salt air from the coast and winter humidity create harsh conditions, springs often fail earlier than the national average. A spring under tension can unwind violently when it breaks, potentially causing serious injury.
Listen first. A loud bang or crack in your garage usually means a spring has snapped. This happens fast and without mercy.
Watch for these red flags before it breaks:
- Door opens only partway, then closes on its own, Door feels heavier than usual when you manually lift it, Visible gaps or rust on the spring itself, Door tilts to one side (one spring may have already failed) - Opener runs but the door doesn't move
If you notice any of these, stop using the door immediately. A snapped spring puts extreme load on your opener and can cause the door to fall suddenly.
I recommend reading our post on garage door repair troubleshooting in Groton to identify other issues, but spring problems require professional intervention. Do not attempt to adjust or replace springs yourself.
Every year, emergency rooms treat people injured by garage door springs. These injuries happen because homeowners assume springs work like other household tools they can fix.
They don't.
A torsion spring under full tension holds roughly 200 pounds of force. If you slip while adjusting it, that energy releases instantly. Fingers get crushed. Faces get cut. Hands get broken.
Professional technicians use specialized tools, proper lifting equipment, and years of experience. They know how to safely discharge tension and install springs so your door operates smoothly.

Spring replacement typically costs between $200 and $400 per spring, depending on the type and quality. Most jobs take 1 to 2 hours. If both springs have failed (common when one breaks first and the other carries extra load), expect to replace both at once.
That upfront cost beats the alternative. Ignoring a snapped spring leads to:
- Damaged garage door opener (adds $300 to $500) - Emergency service calls, Potential injury claims, Door becoming unusable until fixed
We've written a detailed guide on garage door spring replacement costs in Groton. It covers the full breakdown and factors that influence pricing.

Spring failure is one of the few garage door problems that truly demands immediate action. Delaying puts your family at risk and can damage your opener beyond repair.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years under normal use, or roughly 10,000 to 20,000 cycles. Coastal areas like Groton may see shorter lifespans due to rust and humidity.
Can I replace just one spring if only one breaks? It's safer to replace both springs at the same time. When one breaks, the other has already endured the same wear and is close to failure. Replacing both ensures balanced, smooth operation.
How much does a garage door spring cost? Spring replacement ranges from $200 to $400 per spring, plus labor. Torsion springs cost slightly more than extension springs. Get a free estimate from Groton Garage Doors by calling (860) 362-3458.
What happens if I don't replace a broken spring? Your door will either not open at all or open partially and close suddenly. The opener will strain and likely fail next, costing an additional $300 to $500 to replace.
Is spring replacement covered by homeowner's insurance? Most policies don't cover spring failure because it's considered wear and tear. Check your specific policy, but plan to pay out of pocket for this repair.
