A snapped garage door spring means your door won't open, and you're stuck. This isn't just inconvenient; it's a safety hazard and a sign your system needs immediate attention. The good news: it's fixable, usually the same day, and understanding what happened helps prevent it next time.
Your garage door weighs between 300 and 500 pounds. Two springs (or sometimes one, depending on your system) carry nearly all that load every single day. They're under constant tension, coiling and uncoiling thousands of times over their lifespan.
Springs last roughly 7 to 9 years under normal use. That's about 10,000 to 15,000 cycles. When a spring finally fails, it doesn't always happen gradually. Most homeowners hear a loud bang, then find their door won't budge.
Two types of springs support most residential doors in Andover and surrounding Connecticut towns:
Torsion springs mount horizontally above your door opening. They twist to balance the weight. Extension springs run along the upper corners, stretching and contracting. Torsion springs are more durable but more expensive to replace. Extension springs wear out faster but cost less upfront.
When a spring snaps, the other one usually fails within weeks. That's why professionals replace both at once, even if only one broke.
Metal fatigue is the main culprit. Every time you open and close your door, the spring loses a tiny bit of strength. Over years, this adds up. But several factors speed up failure:
Lack of maintenance accelerates wear. If you haven't had your springs and hardware lubricated in over a year, friction is eating away at them faster. Our guide on garage door maintenance in Andover covers how regular care extends spring life.
Rust and moisture also weaken springs. Andover winters and humidity create ideal conditions for corrosion. Rusty springs are brittle springs.
Poor installation matters too. If a technician didn't set the correct spring tension when your door was new, the springs work harder than they should. Over time, this imbalance causes one to fail prematurely.
Finally, overuse shortens spring life. Garages that open and close 20+ times daily (like commercial spaces) burn through springs faster than typical homes.

A single spring replacement typically runs $150 to $300 for the part and labor, depending on the type. Torsion springs cost more than extension springs. If both need replacement (which is standard practice), budget $300 to $600 total.
This is why preventive maintenance saves money. A simple annual inspection costs under $100. Catching a worn spring before it snaps prevents an emergency call and keeps you from paying rush fees.

If your spring just snapped:
1. Don't force the door open manually. A broken spring means no counterbalance. The door can fall suddenly and cause serious injury. 2. Don't use the opener. It will strain trying to lift a door without spring support. 3. Call a professional immediately. Garage Door Andover offers same-day estimates and emergency repair.

How long do garage door springs last? Most residential springs last 7 to 9 years or roughly 10,000 to 15,000 open/close cycles. Maintenance, climate, and usage frequency all affect lifespan. Springs in humid areas or high-use garages may fail sooner.
Can I replace one spring or must I replace both? Professionals always recommend replacing both springs at the same time. The surviving spring is the same age and wear level, so it will likely fail within weeks. Replacing both ensures balanced operation and prevents repeat emergency calls.
What's the difference between torsion and extension springs? Torsion springs mount above the door and twist to lift it. They're more durable and safer but cost more to replace. Extension springs run along the sides and stretch. They're less expensive but wear out faster and pose greater safety risks if they snap.
Is a snapped spring an emergency? Yes. A broken spring leaves your door stuck and creates a safety hazard. Never try to open it manually or force the opener. Contact a professional immediately for same-day service.
How much does spring replacement cost in Andover? Single spring replacement ranges from $150 to $300. Both springs typically cost $300 to $600, including labor. Torsion springs cost more than extension springs. Call (860) 809-4505 for a free estimate tailored to your door.
