Garage Door Torsion vs. Extension Springs in Trumbull: Which Do You Have?
2026-09-07 7 min read
If you've ever dealt with a stuck garage door, chances are a spring problem was behind it. Most homeowners in Trumbull don't know which type of spring sits above their door, let alone how it works or when it'll fail. After 15 years on trucks in this area, I've seen the same confusion play out a hundred times over. The good news: understanding torsion versus extension springs takes five minutes and could save you a panicked call down the road.
What Are Garage Door Springs?
Your garage door weighs between 300 and 700 pounds. You're not lifting that by hand. Springs counterbalance that weight, making your opener's job manageable and keeping the door moving smoothly. Without functioning springs, your door either won't open at all or drops like a stone. That's why a snapped spring feels like an emergency. It is one.
Two main types handle this job in Trumbull homes: torsion springs and extension springs. They work on completely different principles, fail differently, and cost different amounts to replace.
Torsion Springs: The Heavy Lifters
Torsion springs sit horizontally above your garage door, mounted on a steel shaft. When your door closes, the springs twist like a tourniquet, storing energy. When you press the opener button, that stored energy unwinds and lifts the door.
Think of it like a watch spring. The spring doesn't extend or compress much. It rotates. This rotation is what does the work.
Torsion springs are the industry standard in modern homes, especially newer builds across the Connecticut area. They last 7 to 9 years on average, sometimes longer if you're not using your garage door constantly. One torsion spring typically handles the whole load, though some setups use two.

The advantage of torsion springs: they're more durable and predictable. The downside: when one snaps, the whole door becomes inoperable. If you notice your door hanging unevenly or hear a loud bang from the garage, that's often a snapped torsion spring. Don't force the door open. Call us instead.
Extension Springs: The Older Approach
Extension springs run vertically along each side of your garage door opening. As the door closes, these springs stretch. As it opens, they contract, pulling the door up via cables and pulleys.
If torsion is a watch spring, extension springs are rubber bands. They extend and release. Older homes in Trumbull, built before the 1990s, typically use extension springs. They're cheaper to install upfront but tend to wear out faster, especially in humid Connecticut winters.
Extension springs last 5 to 7 years. Because there are usually two (one on each side), losing one doesn't immediately lock your door like a snapped torsion spring does. However, the remaining spring now bears double the load and fails quickly afterward.
Extension springs also require safety cables running through the center of each spring. These cables catch the spring if it snaps, preventing it from rocketing across your garage at dangerous speeds. It's a critical safety feature that torsion springs don't need.
How to Tell Which You Have
Stand in your garage and look above the door. If you see a horizontal shaft with springs coiled around it, you have torsion springs. If you see springs running up and down on the left and right sides, those are extension springs. Still not sure?

The type matters because replacement cost, installation time, and safety protocols differ. Learn more about repair versus replacement options in our guide to spring repair and replacement.
Why Springs Fail
Springs fail because they're under constant stress. Every cycle (open and close) counts as one cycle. Over 7 to 9 years, that's thousands of cycles. Metal fatigues. Springs lose their tension and eventually snap.
Weather plays a role too. Trumbull winters are rough on metal. Rust weakens springs from the inside out. Humidity accelerates corrosion. If you haven't had your door serviced in a year or more, rust could be eating away at your springs right now.
Lack of lubrication also speeds failure. Springs need periodic oiling to reduce friction and slow rust. Most homeowners skip this. Learn what garage door maintenance really involves so you can extend your springs' life by 1 to 2 years.
What to Do When a Spring Snaps
Never try to replace a spring yourself. These components are under extreme tension. A slip can cause serious injury. I've seen garage doors come off their tracks, springs whip across garages, and fingers crushed. It's not worth the risk.
Call us for same-day service if you suspect a spring failure. We'll diagnose the problem, give you a transparent estimate, and handle the replacement safely. Most spring replacements in Trumbull take 1 to 2 hours.
Garage door springs in Trumbull aren't cheap. A single torsion spring runs 200 to 300 dollars installed. Extension springs cost 150 to 250 dollars each. But a functioning door is non-negotiable for security and convenience. The earlier you catch wear, the better your options.
Don't wait for a snapped spring to ruin your morning. If your door is moving slowly, making noise, or sagging on one side, those are warning signs. Get a free estimate today and let our team assess whether repair or replacement makes sense for your situation.
Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years, while extension springs last 5 to 7 years. Lifespan depends on usage frequency, maintenance, and local weather conditions. Regular lubrication can extend life by 1 to 2 years.
Can I replace just one spring if I have two? With extension springs, replacing only the broken one leaves the other under double stress, causing fast failure. Replace both at the same time to avoid a second emergency call within months.
How much does spring replacement cost near me? Spring replacement in Trumbull typically ranges from 200 to 600 dollars depending on the type and your door's configuration. We provide free estimates and same-day service options.
What's that loud bang I heard from my garage? A sudden loud noise almost always means a snapped spring. Stop using your door immediately and call for professional service. Attempting to operate the door with a broken spring risks injury and additional damage.
Do I need both springs replaced even if only one broke? Yes, if you have extension springs. If you have torsion springs and only one is installed, you'll need to replace that single spring. We'll confirm your setup during a free inspection.
