In our 15 years serving Greenwich homeowners, we've seen this problem again and again: a garage door that suddenly won't budge, and the culprit is always the same. A snapped torsion or extension spring has just failed, leaving your door heavier than a loaded truck bed. The good news? It's fixable fast. The bad news? It's not a DIY job, and waiting makes it worse.
Garage door springs don't fail because they're cheap or poorly made. They fail because they're under constant, brutal stress. Every time your door opens and closes, those springs handle roughly 10,000 to 20,000 cycles before they wear out. In Connecticut, where winters are harsh and humidity swings are wild, metal fatigues faster.
Most homeowners don't realize how much weight a spring supports. A typical residential door weighs 300 to 400 pounds. The springs do nearly all the lifting work. That's why a snapped spring happens suddenly, not gradually. One day it's fine. The next day, you hear a loud bang (sometimes mistaken for a gunshot), and your door locks in place.
Torsion springs, which sit above the door, tend to last 7 to 9 years with normal use. Extension springs, mounted on the sides, sometimes fail even sooner if they're not properly balanced. Metal brittleness, rust from salt and moisture, and tiny stress fractures all play a role. Greenwich's proximity to the coast means salt air accelerates corrosion on metal components.
The internet is full of DIY garage door spring videos. Don't watch them. Springs under tension hold enough energy to cause serious injury. When a torsion spring snaps, the bar it was wound around can spin violently. Extension springs can snap like a whip. Fingers, hands, and faces have been badly hurt this way.
A professional technician has the right tools, knowledge of spring tension calculations, and insurance. We can diagnose whether you need a torsion or extension replacement, ensure both springs are matched (critical for balanced operation), and test the door afterward to confirm it's safe. If you try this yourself, you're betting your safety and potentially damaging the garage door opener in the process.
**Need garage door springs in Greenwich today?** Call (475) 264-4523. We cover same-day service across the area.
Spring replacement cost depends on the type, quality, and whether you need one or both springs replaced. If one has snapped, the other is usually close behind. Visit our garage door cost and pricing guide for a detailed breakdown of what to expect in 2026.
A professional estimate takes 15 minutes. Replacement itself takes 1 to 2 hours. We can typically schedule same-day service if you call before 2 p.m. Emergency calls outside business hours are possible depending on availability.
Quality matters here. Cheap springs fail faster and create more risk. We use residential-grade torsion and extension springs rated for 15,000 to 25,000 cycles, which gives you years of reliable service. Cheap springs might save you $50 upfront but cost you another service call in 18 months.
The best strategy is prevention. Regular maintenance catches worn springs before they snap. Our garage door opener maintenance guide covers the habits that extend spring life: keeping the door balanced, lubricating hinges and rollers, and monitoring for rust or visible wear.
If you hear creaking, see rust spots, or notice the door feels unbalanced (one side rises faster than the other), call us for an inspection. A $100 estimate now beats a $400 emergency repair at midnight. Schedule a free quote here to have a technician evaluate your door's condition.
Winters in Connecticut are especially tough on springs. Cold makes metal brittle. Salt and moisture accelerate corrosion. If your door is over 7 years old, we recommend a pre-winter inspection to catch problems before they become emergencies. Read more about why Greenwich winters are so hard on springs in our seasonal guide.
Don't wait for a snapped spring. If your door is slow to open, sticks halfway, or feels heavy, contact us. A snapped spring is not something you can manage with a temporary fix. Your door will stay stuck until it's repaired. Your garage opener will burn out trying to lift a door without spring support. And you lose safe access to your home.
Call (475) 264-4523 now for a same-day estimate. We serve Greenwich and surrounding areas with honest pricing and fast turnaround. Visit our services page to learn more about spring repair and replacement options.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (roughly 10,000 cycles). Extension springs may wear faster, especially in humid or coastal climates like Greenwich where salt air accelerates corrosion.
Can I replace just one spring? No. If one spring has failed, the other is under extra strain and will fail soon after. Replacing both ensures balanced, safe operation and prevents another emergency repair in weeks.
How much does a spring replacement cost? Cost ranges from $250 to $500 depending on spring type and quality. A professional estimate is free and takes 15 minutes.
What should I do if my spring snaps? Stop using your door immediately. Don't try to manually lift it or force the opener. Call a professional technician. Attempting DIY repair risks serious injury.
Why did my spring break so suddenly? Springs fail due to metal fatigue, corrosion, or unbalanced stress over thousands of open/close cycles. Cold weather and salt air in Connecticut accelerate wear. Most breaks happen without warning.
