Extension Springs vs. Torsion Springs in Hillsboro: Which Fails First?
2026-09-02 7 min read
In our years serving Hillsboro, we've seen this problem again and again: homeowners don't know which type of spring sits above their garage door until one snaps without warning. Extension springs and torsion springs fail in completely different ways, and understanding the difference could save you from injury or a costly emergency call. The short answer is that extension springs tend to fail first and more visibly, while torsion springs fail catastrophically with almost no warning.
What's the Difference Between Extension and Torsion Springs?
Torsion springs sit horizontally above your garage door opening and twist to lift the door. Extension springs run along the tracks on either side of the door and stretch as the door closes. Both carry the full weight of your door, which in Hillsboro averages 300 to 400 pounds. See our guide on snapped garage door spring in hillsboro? here.
Torsion springs are engineered to last 15,000 to 20,000 cycles (roughly 7 to 9 years with normal use). Extension springs last slightly longer, around 10,000 cycles, but they wear unevenly because each side bears load independently. This asymmetry is where problems begin.
Why Extension Springs Fail First
Extension springs give you warning signs. As they age, they lose elasticity gradually. You'll notice your door opens slower or feels heavier. The springs may make creaking sounds during operation. These signals give you time to call for service before they snap completely. Read about when to replace your garage door opener in hillsboro: signs you can.
When an extension spring finally breaks, it usually does so one side at a time. Your door will tilt or hang unevenly. It won't fall on your car or crush your hand. It's still dangerous and still requires professional repair, but you have a window to act safely.

Why Torsion Springs Fail Catastrophically
Torsion springs fail with almost zero warning. One moment your door operates normally. The next moment, you hear a loud bang. The spring has snapped, and your garage door becomes a 300-pound dead weight.
If you're opening the door when this happens, it falls. If someone is beneath it, serious injury or death is possible. If you're closing it, the opener motor strains and often burns out, adding $300 to $600 to your repair bill.
Torsion springs fail suddenly because they're under constant tension. Unlike extension springs that stretch and release, torsion springs twist under load every single day. Metal fatigue builds invisibly until the break point.

Which Type Do You Have?
Most older Hillsboro homes (built before 2000) use extension springs. Newer construction and most modern replacements use torsion springs because they're safer and last longer. Torsion is the industry standard now.
To identify yours, look above your closed garage door. If you see two springs running horizontally along the tracks on either side, those are extension springs. If you see one or two springs sitting horizontally above the door opening itself, those are torsion springs.
Never touch either type. Both are under extreme tension and can cause severe lacerations or broken bones if they snap while you're working on them.
The Cost Difference
Extension spring replacement in Hillsboro typically costs $150 to $250 per spring. Torsion spring replacement runs $200 to $400 per spring. A snapped spring on your garage door requires professional replacement. Attempting DIY repair with these springs is how people end up in emergency rooms.

Maintenance Reduces Failure Risk
Regular lubrication of your springs extends their life by 1 to 2 years. Keeping your garage door properly balanced also reduces spring stress. If your door pulls to one side or feels heavy, have it inspected immediately. Unbalanced doors wear springs unevenly and fail sooner.
We recommend professional maintenance every 12 months. This includes checking spring tension, lubricating all moving parts, and testing the safety reverse feature on your opener. Schedule a free quote today and let our team assess your garage door springs and when to replace them.
What to Do if Your Spring Snaps
If you hear a loud bang or your door suddenly becomes impossible to open or close, do not force it. Do not attempt to manually lift it. Call a professional immediately. A snapped spring is an emergency because the door is no longer safely supported.

Frequently Asked Questions
Which spring type is safer, extension or torsion? Torsion springs are safer because they fail suddenly but don't drop the door in stages like extension springs do. However, both types require professional replacement. Never attempt DIY spring repair.
How often should I replace garage door springs in Hillsboro? Extension springs last 7 to 10 years with normal use. Torsion springs last 7 to 9 years. Replace them proactively rather than waiting for failure to avoid emergency costs.
Can I replace just one spring if the other is fine? For extension springs, yes, you can replace one at a time. For torsion springs, we recommend replacing both together to maintain balanced operation and avoid premature failure of the remaining spring.
What causes springs to fail early? Lack of lubrication, unbalanced doors, extreme temperature changes (common in Oregon's wet winters), and frequent opening/closing all accelerate spring wear and shorten lifespan.
Is a snapped spring an emergency? Absolutely. A snapped spring means your door is unsupported and dangerous. Do not use the door and call a professional immediately to prevent injury or additional damage to your opener system.
