Torsion vs. Extension Springs in Kent: Which One Do You Have?
2026-08-09 7 min read
If you've ever had a garage door that won't budge, the problem usually traces back to one component: the spring system. Most homeowners in Kent don't know the difference between torsion and extension springs, but that gap in knowledge can cost you money when something snaps. Here's what you actually need to know.
The Two Types of Garage Door Springs
Your garage door weighs between 300 and 500 pounds. That weight doesn't lift itself. Two spring systems handle this job in homes across Kent and the surrounding area: torsion springs and extension springs.
Torsion springs sit above your door on a metal shaft. They wind up and release energy as the door opens and closes. Think of them like a clock spring. They're the most common type in newer homes and commercial setups because they last longer and distribute force more evenly.
Extension springs hang on either side of your door, running parallel to the tracks. They stretch and contract to manage the door's weight. You'll find these more often in older homes, garage conversions, and budget installations.
The difference matters because each type fails differently and costs differently to replace.
Why Torsion Springs Last Longer
Here's what I've seen on hundreds of service calls: torsion springs typically last 7 to 9 years with normal use, while extension springs often give out in 5 to 7 years. That's because torsion springs handle stress more efficiently. The wound design means less strain per cycle.
Extension springs work harder because they have to overcome the full weight of the door during the opening stroke. Over time, that constant stretching fatigues the metal. The coils weaken. A snapped spring can drop your garage door on your car, a bike, or worse. If you suspect either system is wearing out, don't wait. Check our post on warning signs your springs need replacing now.

Cost Differences Between the Two
Torsion spring replacement typically runs $150 to $300 per spring, depending on length and weight rating. Extension springs cost $50 to $150 per spring. But here's the catch: extension springs often come in pairs, and if one fails, the other usually follows within months. That means you're often replacing both.
Labor matters too. Torsion springs require more specialized installation because the shaft is under intense tension. A technician needs proper tools and training to wind them safely. Extension springs are simpler to swap, so labor costs are lower. If you're comparing estimates, ask whether the quote covers both springs or just one. Also ask about the full cost breakdown before committing.
How to Tell Which Type You Have
Stand in your garage and look above your door. If you see a thick metal shaft running horizontally with a wound spring wrapped around it, that's torsion. If you see springs running along the sides of the door opening, parallel to the tracks, those are extension springs.
This matters when you call for service. Tell the technician what type you have, and they can prepare the right equipment and give you an accurate estimate before arriving.
What Happens When a Spring Snaps
A snapped spring makes a loud bang. Your door won't open. The opener motor strains and may burn out trying to lift all that weight with zero spring assist. You're stuck.
This is why I recommend never trying to open a garage door with a broken spring yourself. The door can fall unexpectedly. If you're in this situation right now, here's what to do in an emergency.
When to Replace vs. Repair
If you have a snapped spring, replacement is your only real option. Springs can't be welded or repaired safely. The stress and temperature cycling mean a fix won't hold.
If a spring is showing age but hasn't broken yet, replacing both springs at once (even if only one is failing) makes financial sense. You avoid a second service call in a few months. It's tempting to replace just the bad one, but I've learned the hard way that the other one is usually close behind.
Getting the Right Spring the First Time
Garage door springs are rated by a number called the "cycle life" or "wire size." Wrong specs mean poor performance or failure. When you call Garage Door Kent or any local technician, have your door's weight and dimensions ready. Measure the door's width and note the torsion shaft diameter if you can.
Our team can size your system properly over the phone and come prepared with the exact spring you need. Many customers appreciate same-day turnaround because we carry common sizes in our trucks.

Preventing Future Spring Failures
Regular lubrication extends spring life by 2 to 3 years. Once yearly, spray a light oil on the springs and tracks. Avoid harsh cleaners that strip protective coatings.
Don't ignore warning signs. If your door feels heavier, jerks unevenly, or moves slowly, those are early indicators of spring fatigue. Addressing it early prevents sudden failure and keeps you safe.

Frequently Asked Questions
How much does a garage door spring replacement cost in Kent? Torsion springs run $150 to $300 per spring plus labor. Extension springs are $50 to $150 each. Most homes need both springs replaced at the same time. Total costs usually land between $300 and $600 for parts and professional installation.
Can I replace a garage door spring myself? Torsion springs are under extreme tension and require special tools and expertise. Attempting DIY installation risks serious injury. Extension springs are less dangerous but still risky. We recommend hiring a licensed technician for safety and warranty protection.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with average use, rated for 10,000 to 15,000 cycles. Extension springs last 5 to 7 years. Frequency of use and climate conditions affect lifespan significantly.
What's the difference between torsion and extension springs? Torsion springs sit above the door and wind to lift it. Extension springs hang on the sides and stretch. Torsion springs last longer, cost more, and require professional installation. Extension springs are cheaper but fail sooner.
Why do garage door springs snap suddenly? Springs weaken over thousands of opening and closing cycles. Metal fatigue develops invisibly. When stress exceeds the weakened material's capacity, the spring breaks suddenly without warning, usually during normal use.
