Here's what most homeowners don't realize about garage door springs: you likely have one of two completely different types holding up that 300-pound door, and they fail in different ways. After 15 years on service calls across Old Saybrook and the Connecticut shoreline, I've seen springs snap at 2 a.m. on a Sunday more times than I care to count. The good news? Understanding which type you have saves you money and headaches.
Torsion springs sit horizontally above your door, twisting to lift the weight. Extension springs run along the sides of the door track, stretching as the door opens. Most homes in Old Saybrook use torsion springs because they're safer, more durable, and handle frequent use better. Extension springs are cheaper upfront but wear faster and pose a pinch hazard.
Torsion springs typically last 7 to 9 years with normal use (about 10,000 cycles). Extension springs last 5 to 7 years. If your door opener runs daily, you're looking at the lower end of that range. One spring handles roughly half the load, so both sides wear evenly when they're the same age.
Springs fail because of metal fatigue, not defects. Every time your door opens and closes, the coil flexes slightly. After thousands of cycles, that metal loses its ability to bounce back. Rust accelerates this process, especially near the coast where salt air corrodes uncoated metal faster.
A snapped spring won't break the door or the opener, but it will make the door heavy and unbalanced. Trying to force it open risks garage door damage or personal injury. If you hear a loud bang from the garage, that's usually a spring giving way. Don't ignore it. Read more about snapped garage door springs in Old Saybrook and what to do if this sounds familiar.

A single torsion spring replacement typically runs $150 to $300 in labor, plus the spring itself (usually $50 to $150). Extension springs are cheaper but require more frequent replacement. Most technicians replace both springs at once to avoid a second service call within months.
The total cost depends on spring size, door weight, and whether you need a safety cable installed. We always recommend replacing both springs together, even if only one snapped. Here's why: the remaining spring has already endured the same wear cycles. Replacing one now means replacing the other in 6 to 12 months.

Spring replacement is not a homeowner project. Torsion springs are under extreme tension (200 to 400 pounds of force) and can cause serious injury if mishandled. I've seen fingers broken and eyes injured by springs that went wrong. Professional technicians have the right tools, experience, and insurance.
Old Saybrook Garage Doors dispatches trained technicians who can diagnose, quote, and install new springs the same day in most cases. We carry standard sizes on our trucks, so you're not waiting a week for parts.
Spring life extends when you reduce friction and prevent rust. Lubricate the spring with light machine oil or garage door lubricant every six months. Wipe down the spring after winter salt spray. Check that the door opens and closes smoothly without jerking or sagging.
A full garage door tune up catches spring wear early, along with opener issues and seal problems. See what's included in a complete garage door tune up to understand the full scope of maintenance available.

Most springs fail without warning, but some show signs: slow opening, jerky movement, or uneven door height. These are red flags that springs are nearing the end of their life.

How do I know if my garage door spring is broken? A loud bang from the garage, a door that won't open, or one side hanging lower than the other are classic signs. Most homeowners notice the door feels suddenly very heavy or jerky. Don't force it; call a technician for a safe inspection.
Can I replace one spring instead of both? Technically, yes, but we don't recommend it. Both springs have the same age and wear cycles. Replacing one means the other fails within months, requiring another service call. Replace both at once to save money and hassle long-term.
How long does spring replacement take? A professional can replace both torsion springs in 1 to 2 hours. We often complete the job during a morning or afternoon appointment, depending on your schedule and door type.
Do extension springs need replacing as often as torsion springs? Yes, actually more often. Extension springs last 5 to 7 years compared to torsion springs at 7 to 9 years. They're also less safe because they can snap and whip across the garage without a safety cable.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly with an audible bang and leaves the door inoperable. A worn spring weakens gradually, causing slow opening or uneven movement. Both require replacement, but worn springs give you a window to schedule service without emergency pressure.
