Garage Door Spring Types in Arlington: Torsion vs. Extension Explained
2026-08-04 7 min read A2Z Garage Doors
Your garage door springs are the hardest-working component in your entire system, yet most homeowners don't think about them until something breaks. Understanding whether you have torsion or extension springs isn't just trivia. It directly affects your repair cost, timeline, and safety. Knowing this difference can save you hundreds of dollars and help you make informed decisions when a spring fails.
What Are Garage Door Springs, and Why They Matter
Garage door springs counterbalance the weight of your door, making it light enough for your opener to lift safely. Without functioning springs, your opener would burn out in weeks trying to lift a 300 to 400 pound door on its own. Springs typically last 7 to 9 years with normal use, but that lifespan depends heavily on your door's weight, how often you use it, and which type you have installed.
Most Arlington homes use one of two spring styles. Recognizing yours helps you communicate clearly with repair technicians and understand what replacement will actually cost.
Torsion Springs: The Standard Choice
Torsion springs sit horizontally above your garage door opening, wound tightly like a coil. When the door closes, tension builds inside the spring. When you open it, that stored energy unwinds and lifts the door smoothly. Most modern homes in Arlington and the surrounding area rely on torsion springs because they're durable, efficient, and provide consistent lift over time.
One torsion spring typically handles the entire load. Larger or heavier doors sometimes have two springs working together. The trade-off is that torsion springs are under enormous pressure. When one snaps, the failure is often sudden and complete. You'll hear a loud bang, and your door will become nearly impossible to open manually.
Torsion springs cost more to replace than extension springs, usually ranging from $200 to $400 per spring depending on your door's weight and local labor rates. However, they last longer and require less maintenance, making them a better long-term investment. If you're unsure whether you have torsion springs, look above your door frame. You'll see a horizontal shaft with a wound coil around it.
Extension Springs: The Budget Alternative
Extension springs run vertically along both sides of your door opening, stretching and contracting as the door moves. They're lighter-duty than torsion springs and typically cost $100 to $200 to replace. Older homes and lighter garage doors often use extension springs because the initial installation is cheaper.
The downside? Extension springs wear faster and require more frequent replacement. They also pose a slightly higher safety risk because they can snap with less warning and potentially allow the door to drop suddenly. That's why modern building codes increasingly favor torsion systems.

How to Identify a Snapped Spring
A snapped spring is an emergency. You shouldn't attempt to open or close your door manually, as this can cause injury or additional damage. Both spring types fail in similar ways: the door becomes heavy, won't open smoothly, or makes grinding or clicking sounds as the opener struggles.
If you're hearing these warning signs, our guide on recognizing warning signs your springs need help now covers the full diagnostic process. Don't ignore these signals. A failing spring can damage your opener, door panels, and cables within days.
Repair vs. Replace: The Real Cost
When a torsion spring fails, replacement is almost always the right choice. Repair isn't really an option because the internal damage is irreversible. With extension springs, replacement is similarly the standard solution.
The true cost includes not just the spring itself, but labor, hardware, and any damage to related components. Our detailed breakdown on spring replacement cost and timeline walks through exactly what to expect before a technician arrives. Understanding these costs upfront helps you budget and avoid surprise invoices.
Why Spring Type Matters for Your Specific Home
Your spring type depends on your door's weight, your home's age, and the opener's capacity. Newer construction typically defaults to torsion springs because they're safer and more reliable. Older Arlington homes might still have extension springs that work fine but need more frequent attention.

Frequently Asked Questions
What's the difference between a snapped torsion spring and a broken extension spring? Both leave your door inoperable, but torsion failures are usually sudden and loud (you'll hear a bang). Extension springs tend to fail more gradually, with increasing noise and resistance before complete failure. Either way, stop using your door immediately and call for professional help.
Can I replace just one spring if I have two? Not recommended. If one spring has failed, the other is likely close behind, especially if both are the same age. Replacing only one creates an imbalance and puts extra stress on the new spring, shortening its lifespan significantly.
How long does a spring replacement take? Most replacements take 1 to 2 hours from start to finish. Same-day service is available in Arlington when you call early in the day. We'll provide a realistic timeline during your estimate.
Are torsion springs always better than extension springs? For safety, durability, and long-term value, yes. Torsion springs last longer and perform more consistently. Extension springs are cheaper upfront but require replacement sooner, so the lifetime cost often favors torsion systems.
What causes springs to wear out faster? Heavy use, extreme temperature swings (especially harsh winters), lack of lubrication, and oversized doors all accelerate wear. Regular maintenance and lubrication can extend spring life by a year or two.
