Torsion vs. Extension Springs in New Milford: Which One Do You Have?
2026-07-07 7 min read A2Z Garage Doors
Most homeowners don't know which type of spring holds up their garage door until one snaps. The two main designs are torsion and extension springs, and they work very differently. Understanding which one you have now saves you money later and keeps you safe during repairs.
What Are Garage Door Springs, and Why They Matter
Your garage door weighs 300 to 500 pounds. Without springs, it would crash down or require superhuman strength to lift. Springs counterbalance that weight, making the opener's job manageable. They're also among the most dangerous parts of your door system because they store enormous tension. A snapped spring doesn't just stop your door from opening. It can injure someone or damage your vehicle.
Springs typically last 7 to 9 years with normal use. After that, they fatigue and fail. Many homeowners discover this problem at the worst time. That's why knowing your spring type matters now, before an emergency happens.
Torsion Springs: The Most Common Type
Torsion springs sit horizontally above your garage door opening. They twist and wind tightly, storing energy as you close the door. When you press the opener button, that stored tension unwinds and lifts the door smoothly.
Torsion springs are the standard in modern garages because they're more durable and reliable than older designs. They last longer, wear more evenly, and provide consistent lifting power. They're also safer because they're mounted high and far from foot traffic.
The downside? Torsion spring replacement requires specialized tools and serious knowledge. A snapped torsion spring leaves your door completely stuck. You'll need professional help immediately. New Milford Garage Doors can usually handle torsion spring replacement same day, depending on your location in town.
Extension Springs: Older but Still Found in Many Homes
Extension springs run along both sides of your door, above the horizontal tracks. They stretch and contract as the door moves up and down, extending and retracting to balance the weight.
If your house was built before 2000, you likely have extension springs. They're cheaper upfront, which is why builders favored them for decades. However, they wear faster and need more frequent adjustment than torsion springs.
Extension springs are also riskier. They're positioned near the tracks where people walk and children play. If a cable breaks or a spring snaps, the spring can whip across the garage. Safety cables help contain the damage, but extension spring failures are inherently more hazardous.

How to Tell Which Type You Have
Stand inside your garage and look above the door. If you see a tightly wound metal rod running horizontally across the top center, you have torsion springs. If you see two springs running vertically along the sides near the tracks, you have extension springs.
Don't touch or attempt to adjust either type yourself. The tension is extreme, and mistakes cause serious injuries. Even simple adjustments require professional equipment and training.
Cost and Replacement Considerations
Torsion spring replacement costs more than extension spring replacement because the work is more complex. However, the total cost depends on several factors: how many springs you need, your door's weight, your location within New Milford or surrounding towns like Danbury, and whether you're replacing one or both springs at once.
Most professionals recommend replacing both springs at the same time, even if only one has failed. Springs wear at similar rates. Replacing just one means the other will likely fail within weeks or months, and you'll pay for a service call twice.

Why Maintenance Prevents Costly Failures
Regular maintenance catches spring problems before they become emergencies. A technician can inspect spring tension, check cable condition, and lubricate moving parts. This doesn't prevent springs from aging, but it extends their life and catches early warning signs.
Small issues like squeaking, jerky motion, or uneven opening suggest spring wear. Addressing these issues promptly prevents sudden failures that leave you unable to access your garage. Learn more about routine maintenance that saves money over time.
When to Call a Professional
If your door opens slowly, closes unevenly, or makes loud noises, springs may be wearing out. If you hear a loud bang or snap, a spring has failed. Don't try to open the door manually. Don't use the opener. Call for help immediately.

Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use. Frequent opening and closing, humidity, and temperature swings can reduce lifespan. Springs are rated by number of cycles, usually 10,000 to 15,000 total lifts.
Can I replace just one spring? Technically yes, but professionals recommend replacing both springs simultaneously. Springs wear at similar rates. Replacing one means the other will fail soon after, costing you another service call and labor charge within weeks.
Is it safe to manually open my door if a spring breaks? No. A broken spring removes all counterbalance. Your door becomes extremely heavy and dangerous to lift manually. You risk dropping the door on your car, property, or yourself. Always call a professional.
Why does torsion spring replacement cost more? Torsion springs require specialized tools, precise tension adjustment, and expert knowledge to install safely. Extension springs are simpler to replace, but the work is still dangerous and should only be done by trained technicians.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely stops your door from functioning. A worn spring gradually loses tension, causing slow opening, uneven lifting, or strain on your opener. Both need replacement, but snapped springs require immediate emergency service.
