Garage Door Torsion vs. Extension Springs in Longmont: Which Does Your Door Have?
2026-08-08 7 min read
Here's what most homeowners don't realize about garage door springs in Longmont: you probably can't tell which type yours is, and that confusion costs money fast. When a spring fails, misidentifying whether you have torsion or extension springs delays repairs, inflates your repair estimate, and leaves your garage door stuck. I've watched too many people panic after a snapped spring because they couldn't answer a simple question: what's holding up my door right now?
The Two Spring Types That Power Your Garage Door
Your garage door weighs 300 to 500 pounds. Springs handle that weight. You have one of two designs working overhead. See our guide on smart garage door technology in longmont: app and wifi setup explained.
Torsion springs twist and rotate above the door opening. These springs wind tightly, storing rotational energy. When the door opens, they unwind gradually, controlling the descent. Torsion springs typically last 7 to 9 years with normal home use. Most residential doors in Longmont use this design.
Extension springs run horizontally along the upper tracks on each side of the door. These springs stretch and contract like long rubber bands. When the door closes, they extend. When it opens, they contract and pull the cables. Extension springs also last roughly 7 to 9 years, but they wear differently than torsion systems.

The key difference: torsion springs are safer and more predictable. If one fails, the door falls slowly. Extension springs can snap suddenly, and the door drops hard. This matters.
Why Identifying Your Spring Type Matters Now
Confusing these two types creates real problems. A technician arriving for a repair needs to know your spring design before ordering parts. If you tell them you think you have one type and you're wrong, they waste time, you waste money, and your door stays broken longer.
Cost varies too. Garage door springs in Longmont generally run $200 to $400 per spring installed, but torsion springs and extension springs carry different labor costs. Torsion systems require specialized tools and expertise, pushing estimates higher. Extension spring replacement sounds simpler but carries greater safety risk if done incorrectly.
Here's the real kicker: both spring types need professional replacement. I've handled too many DIY disasters where homeowners tried to save money and ended up in the emergency room. Read why DIY spring fixes cost more than calling a professional from the start.

How to Spot Which Type You Have
Look up at your garage door while it's closed. Stay safe. Don't touch anything.
Above the door opening, toward the center, do you see one or two large springs running horizontally across the top? If you see springs along the upper tracks on each side, you have extension springs.
If you see one large spring (or two stacked) wound tightly above the door center, and the spring looks like a coil, you have a torsion system. Torsion springs rest on a shaft that runs the full width of your opening.
If you can't reach or see clearly from inside, take a photo and text it to us. We'll identify your system in seconds. But knowing this now helps you communicate clearly when you call for a repair or schedule a free quote from Garage Door Longmont.
What Happens When Springs Fail
A snapped torsion spring produces a loud bang, then nothing. The door won't move. Your opener hums but can't lift the weight. This is actually the safer failure mode because you know immediately that something broke.
A snapped extension spring also creates a loud noise, but the door might drop or jam unevenly. The remaining spring on the other side pulls the door crooked, binding it in the tracks. This can damage the tracks, panels, and opener motor.
Both scenarios demand professional attention. Neither is a DIY situation. Learn what to do if your spring snaps and why waiting makes repairs more expensive.

Frequently Asked Questions
How long do garage door springs last? Garage door springs typically last 7 to 9 years under normal residential use. The exact lifespan depends on how often your door cycles. High-use doors in cold climates like Longmont may wear faster. A spring cycle counter tracks every open and close. Most springs reach 10,000 to 15,000 cycles before failure.
Can I replace a garage door spring myself? No. Spring replacement involves extreme tension and sharp components that cause serious injury every year. Professional technicians use specialized tools, proper safety equipment, and insurance coverage. One wrong move can result in broken bones or worse. Always hire a licensed technician for spring work.
What's the cost difference between torsion and extension spring replacement? Torsion spring replacement typically costs $200 to $400 per spring installed. Extension springs run $150 to $300 per spring, but labor varies. Torsion systems require more expertise and specialized tools, which increases the total estimate. Get a written quote before work begins.
Why does my garage door make a loud noise but still works? A spring under extreme stress makes loud creaking or popping sounds. This is a warning sign that failure is imminent. Have a professional inspect it immediately. Don't keep using the door, as a complete break could drop it on your car or someone beneath it.
How do I know if my spring is about to fail? Signs include creaking sounds, uneven door movement, the door falling slightly when opening, or visible gaps in the spring. If your door feels heavier than usual or struggles to open all the way, call for an inspection right away. Early detection prevents emergency situations.
