Torsion vs. Extension Springs in Lamona: Which Do You Have?
2026-06-13 7 min read
In our years serving Lamona, we've seen this problem again and again: homeowners don't know what type of spring holds up their garage door, so they buy the wrong replacement and waste money. Your garage door uses either a torsion spring or an extension spring. They work differently, cost differently, and fail differently. Knowing which one you have saves time and prevents overspending on repairs.
What's the Difference Between Torsion and Extension Springs?
Torsion springs sit horizontally above your garage door opening. They twist and unwind to lift the door, storing energy in rotational motion. One torsion spring can often handle the entire weight of your door, which is why many modern doors use this design.
Extension springs hang vertically on both sides of your door tracks. They stretch as the door closes and contract as it opens, using tension to assist the lifting mechanism. Most homes have two extension springs working together because one spring alone isn't strong enough.
The big difference: torsion springs are mounted at the center top and rotate. Extension springs are mounted to the sides and pull. This affects how they fail, how much they cost, and how dangerous they are to replace.
How to Tell Which Type You Have
Look directly above your garage door opening. If you see a horizontal metal shaft with a coiled spring wound around it, you have a torsion spring. That's the most common setup in newer homes and commercial buildings.
If you see springs hanging down on either side of the door tracks (usually with pulleys and cables), those are extension springs. They're more common in older homes and budget installations.
Can't tell from looking? Your garage door documentation or previous repair invoices will list the spring type. Learn more about how garage door springs work and when to replace them if you want the full technical picture.
Cost Differences: Why Torsion Springs Cost More
Torsion springs typically run $200 to $400 per spring, including installation. Extension springs cost $100 to $200 per spring. Why the price gap?
Torsion springs are more expensive to manufacture because they require precise winding and calibration. They also last longer, typically 7 to 9 years with normal use. Extension springs wear out faster, often needing replacement every 5 to 7 years because they endure more friction and stress.
The labor cost also differs. Installing torsion springs requires special tools and expertise because the spring is under extreme tension. One mistake can cause serious injury. Extension springs are simpler to replace, which lowers labor costs.

Why This Matters for Your Budget
If your door has a snapped spring and a contractor quotes you $500 to replace it, but you actually have two extension springs, you're overpaying. Conversely, if someone quotes $150 to replace a torsion spring, that price is unrealistically low and suggests either poor quality or hidden costs.
Getting an accurate estimate starts with knowing your spring type. Check our garage door spring replacement cost guide for realistic Lamona pricing on both types.
Safety Matters: Don't Replace Springs Yourself
Both torsion and extension springs are dangerous when they fail. A snapped torsion spring can cause the door to crash down. Replacing either type requires releasing tension that can cause serious injury. We've helped many Lamona homeowners who tried DIY replacement and ended up spending more on emergency repairs.
Professional technicians have the right tools, training, and insurance. A same-day repair from a qualified company costs less than the hospital visit.
What Happens When Springs Fail?
If your torsion spring snaps, your garage door becomes extremely heavy and the opener won't lift it. You'll hear a loud bang or pop. If an extension spring breaks, the door will feel unbalanced and may jerk to one side.
Either way, stop using the door immediately. A broken spring means your door isn't safely supported. Read our detailed guide if your springs have already snapped.

Frequently Asked Questions
Can I replace one extension spring if the other is still working? Technically yes, but it's not smart. Springs age together. If one is failing, the other is close behind. Replacing both at once costs slightly more upfront but saves you a second service call within months.
Which spring type is better, torsion or extension? Torsion springs last longer and are safer long-term. Extension springs are cheaper upfront but wear out faster. New installations almost always use torsion springs.
How long do garage door springs actually last? Torsion springs last 7 to 9 years with regular use. Extension springs last 5 to 7 years. Frequency of door use affects lifespan significantly.
What's the cost difference for labor between torsion and extension replacement? Labor for torsion spring replacement is typically $150 to $250 because it requires specialized tools. Extension spring labor usually runs $75 to $150 since the job is simpler.
Should I replace my springs before they break? If springs are 8 years old (torsion) or 6 years old (extension), replacement preventive maintenance is smart. It's cheaper than emergency repair and prevents sudden door failure.
