Torsion vs. Extension Springs: Which Does Your Kensington Garage Door Need?
2026-07-04 7 min read
A customer called last Tuesday asking whether their garage door needed a torsion spring or an extension spring. They'd seen both terms online and weren't sure which one was actually broken or how much the repair would cost. Here's the honest answer: most residential garage doors in Kensington use torsion springs, but extension springs still show up on older systems. The type matters because repairs and replacements differ in method, cost, and safety.
Understanding which spring your door has isn't just trivia. It affects how you'll handle a snapped spring, what the estimate will look like, and how quickly we can get you back in business.
How Torsion Springs Work
Torsion springs sit on a horizontal rod above your garage door opening. They twist and unwind to lift and lower the door. Think of them like a clock spring wound extremely tight. When you press the opener button, the spring releases energy, making the heavy door feel weightless.
These springs are the gold standard for modern garage doors. They're more durable, quieter, and balanced better than their extension cousins. A quality torsion spring lasts 7 to 9 years with normal use. When one fails, the door either won't open at all or drops suddenly, which is why we treat snapped springs as emergencies.
The trade-off: torsion springs are under tremendous tension. Replacing them requires specialized tools and genuine expertise. This is not a DIY job. Improper installation can cause serious injury.
How Extension Springs Work
Extension springs run along both sides of your garage door opening, parallel to the horizontal tracks. Instead of twisting, they stretch and contract. When the door closes, they extend. When you open it, they contract and help lift the weight.
You'll find extension springs on older garage doors, lighter doors, or some commercial setups. They're cheaper upfront and easier to replace than torsion springs. However, they don't last as long and require safety cables to prevent injury if they snap. That's a big deal. A snapped extension spring without a safety cable can send metal coils flying like shrapnel.
If your garage door is 15+ years old and has never had spring work done, you likely have extension springs. Newer homes built in the last decade almost always have torsion systems.
Which Type Do You Have?
Look up at your garage door opening. If you see a horizontal rod with what looks like a twisted metal coil running side to side above the door, that's torsion. If you see springs running vertically along the left and right tracks, those are extension springs.

Spring Replacement Cost and Timeline
Torsion spring replacement typically costs more than extension because it demands precision equipment and training. An extension spring swap runs cheaper but carries higher safety risk if done wrong. Both jobs should happen the same day you call. Driving on a broken spring slowly wears out your opener and tracks.

Why Spring Type Matters for Safety
This isn't marketing talk. Spring failure is the leading cause of garage door injuries. A snapped torsion spring means your door is essentially dead weight. An extension spring that breaks without a safety cable becomes a projectile. Either scenario demands immediate professional attention.
If you hear a loud bang from your garage, see your door hanging crooked, or notice it won't move when you press the opener, stop using it and schedule a free quote. Don't try to force it open. Don't call a handyman unfamiliar with springs. Call someone who knows the difference between torsion and extension and has the tools to fix it safely.
We serve Kensington and the surrounding communities, including nearby areas in Summit County. Same-day appointments are usually available for spring emergencies.
Don't Wait on a Broken Spring
A failing or snapped spring won't improve on its own. The longer you wait, the more wear your opener and tracks endure. That turns a $300 spring repair into a $800 opener replacement.
If your door feels heavy, moves slowly, or makes unusual noise, the spring is likely nearing the end of its life. Get a professional assessment now rather than a panic call later.

Frequently Asked Questions
Can I replace a garage door spring myself? We advise against it. Torsion springs are under 200+ pounds of tension. Extension springs can snap without warning. Even small mistakes cause serious injury or death. Professional replacement takes 1 to 2 hours and protects your safety.
How do I know if my spring is about to snap? Listen for creaking or squeaking above the door. Watch for uneven movement or the door sagging on one side. Feel if the door is heavier than normal. These signs mean the spring is weakening and replacement is near.
Do both springs need to be replaced at the same time? Yes. Springs work in pairs. If one is worn, the other is too. Replacing only one creates imbalance and shortens the new spring's life. Always replace both together.
How long do garage door springs last? Torsion springs last 7 to 9 years on average. Extension springs last 5 to 7 years. Heavy use, extreme weather, and poor maintenance shorten this window. Cold winters in Kensington can accelerate wear.
What's the difference between a snapped spring and a worn spring? A snapped spring fails suddenly and prevents the door from opening. A worn spring weakens gradually, making the door feel heavier and harder to operate. Both need replacement, but snapped springs are emergencies.
