In our years serving Caledonia, we've seen this problem again and again: homeowners don't know the difference between torsion and extension springs until one snaps. Torsion springs sit above the door and twist to lift weight. Extension springs run along the sides and stretch. Torsion springs last 7 to 9 years under normal use; extension springs often fail sooner, especially in our Rochester winters.
Torsion and extension springs do the same job in different ways. A torsion spring is a single metal rod that winds up like a clock spring. When you open your door, it unwinds and releases stored energy. Extension springs are two separate coils mounted on cables, one on each side. They stretch as the door goes down and contract as it rises. See our guide on weather stripping & seals in caledonia: stop air leaks now.
Think of it this way: torsion springs are precision instruments. Extension springs are workhorses that take more stress per cycle. Both carry the full weight of your garage door (usually 200 to 400 pounds), but extension springs do it by pulling rather than rotating.
Extension springs fail more often and earlier than torsion springs. We get calls almost weekly about snapped springs near me in Caledonia. Most are extension units. Here's why: extension springs live on the outside edges of your opening, exposed to temperature swings. Cold snaps and humidity changes in upstate New York weaken the metal faster. They also absorb shock from every door cycle differently than torsion designs. Read about garage door repair vs. replacement cost in caledonia: the honest math.
Torsion springs are enclosed above the door, so they're better protected from the elements. They're also engineered to handle the load more smoothly. When a torsion spring does fail, though, it's usually catastrophic. You'll see a loud bang, and your door won't budge. A snapped extension spring sometimes lets you limp the door open or closed, which can be dangerous.

Don't wait for a spring to snap. A door that creaks, struggles to open smoothly, or falls faster than it should is telling you something. Extension springs that look rusty or pitted are candidates for failure within weeks. Torsion springs that squeak when turning need lubrication and inspection.
If your door is over 7 years old and you haven't replaced the springs, budget for a replacement soon. We've found that homeowners who catch early warning signs save hundreds on emergency repairs. Our team at Garage Door Caledonia can spot wear patterns most people miss.

A torsion spring replacement typically runs $200 to $400 per spring, labor included. Extension springs cost less per unit, usually $100 to $200 each, but you always replace both sides at once. The real cost difference shrinks when you factor in a service call.
Many homeowners ask if they can just replace one. We don't recommend it. The remaining spring is already worn. Replacing only one puts uneven stress on your door and opener, which shortens the life of both. You'll be calling us back in months.

This is where you can actually extend spring life. Lubricate your springs and hardware once a year, preferably in fall before our brutal winters hit. Use a silicone-based lubricant, not WD40 (that attracts dirt). Inspect cables for fraying or damage. Check that the door opens and closes evenly.
We also recommend seasonal maintenance. Learn how to avoid costly repairs with a simple maintenance routine that takes less than an hour twice a year.
Don't attempt to replace springs yourself. Torsion springs hold thousands of pounds of tension. A slip or mistake can cause serious injury. We've seen broken fingers and worse. Extension springs are slightly safer to work near, but still dangerous. The cables can snap unexpectedly if tension is released wrong.
Schedule a free quote to have your springs inspected by someone who's been doing this since 2009. We can tell you exactly how much time your current springs have left.
Extension springs fail first because they're more exposed and work harder on every cycle. Torsion springs last longer but fail harder. Either way, knowing which type you have and watching for warning signs will save you money and keep your family safe. Don't wait for a snapped spring to trap your car or worse.

Can I replace just one spring instead of both? No. Springs always wear at similar rates. Replacing only one creates uneven door movement, which stresses your cables and opener. Always replace both torsion or both extension springs together.
How long do garage door springs typically last? Torsion springs last 7 to 9 years under normal use (about 10,000 cycles). Extension springs often fail sooner, especially in cold climates like upstate New York, usually lasting 5 to 7 years.
What's the difference between a torsion and extension spring cost? Torsion springs cost more per spring, typically $200 to $400. Extension springs run $100 to $200 each. However, torsion replacements involve more labor, and most jobs include both springs and installation.
Can I lubricate springs to make them last longer? Yes. Annual lubrication with silicone spray helps, but it won't stop eventual failure. Springs wear out from metal fatigue, not friction. Lubrication slows rust and reduces noise, extending life slightly.
What happens if a spring snaps while the door is opening? A snapped torsion spring will cause the door to drop suddenly, potentially trapping your vehicle or worse. Extension springs may let the door close slowly on one side. Either way, stop using the door and call a professional immediately.
