Here's what most homeowners don't realize about garage door springs: not all springs are created equal, and the type mounted above your door determines everything from how long it lasts to how catastrophic a failure becomes. In Aurora and surrounding areas, the vast majority of residential garage doors use one of two spring systems. Understanding which one you have, and which one fails more suddenly, could save you from a dangerous and expensive emergency.
Your garage door likely uses either a torsion spring or an extension spring system. These aren't interchangeable, and they behave very differently when they wear out.
Torsion springs run horizontally across the top of your door opening, above the actual door panel. They twist and unwind to counterbalance the door's weight as it opens and closes. A typical torsion spring lasts 7 to 9 years with normal use, handling roughly 10,000 to 15,000 cycles (that's about 5 to 8 years for an active family opening the door twice daily).
Extension springs hang vertically on both sides of the door opening. They stretch and contract, working like rubber bands to support the weight. Extension springs usually outlast torsion springs by a year or two, but that advantage disappears quickly if they're not maintained properly.
Torsion springs almost always fail without warning. One moment your door operates normally. The next, you hear a loud bang (sometimes described as a gunshot), and the door becomes too heavy to lift manually. This happens because torsion springs fail catastrophically when the metal fatigues and cracks. There's no gradual degradation.
Extension springs can also snap suddenly, but they're slightly more forgiving because the cable system running through them often catches the broken spring and prevents total collapse. That said, a snapped extension spring still renders your door inoperable and requires professional replacement.

Torsion springs experience more stress per cycle than extension springs. The twisting motion puts intense pressure on a small area of metal. Over time, tiny stress fractures develop in the coils. Eventually, one crack grows large enough that the spring can no longer support the load, and it fails instantly.
Extension springs distribute stress more evenly across their length, which is why they tend to last slightly longer. However, this advantage shrinks if cables aren't lubricated or if springs are sized incorrectly for your door's weight.

Many homeowners delay spring replacement because the door still works. That's a risky assumption. Once a spring reaches the end of its lifespan, failure is inevitable. The only variable is timing. Waiting until a spring snaps forces you into an emergency repair situation, which always costs more than a planned replacement.
If your springs are original to your home, or if you've owned the door without a spring replacement, don't wait for failure. A free estimate from a professional can confirm whether replacement is needed now or soon. Visit our spring replacement cost guide to understand what you're likely to pay and why pricing varies.
This matters more than most homeowners think. If one torsion spring has failed, the other is almost certainly close behind. Replacing both at the same time prevents a second failure weeks later, which would mean paying for service calls and labor twice.
Extension springs present a similar dilemma. When one snaps, inspect the other closely. Cables should be intact and springs should look uniform in color and coil tension. If there's any doubt, replacement of the pair is the safer, smarter choice.

Don't gamble with a failing spring system. A sudden failure doesn't just leave you stranded. It puts stress on your opener, can damage the door itself, and creates a safety hazard if someone's under the door when it fails.

What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door. Extension springs stretch vertically on the sides. Torsion springs fail more suddenly but are more common on heavier doors. Extension springs last slightly longer but distribute weight differently.
How long do garage door springs last? Torsion springs typically last 7 to 9 years (10,000 to 15,000 cycles). Extension springs may last 9 to 10 years. Lifespan depends on climate, frequency of use, and maintenance. Aurora's humidity can accelerate corrosion if springs aren't lubricated annually.
Can I replace one spring if the other breaks? Technically yes, but it's not recommended. If one spring has failed, the other is likely near the end of its life. Replacing both together prevents a second failure within weeks and is more cost-effective overall.
What does a snapped spring sound like? Most homeowners describe it as a loud bang or gunshot coming from the garage. The door becomes suddenly very heavy or immovable. Never attempt to operate the door after hearing this sound.
Is a snapped spring an emergency? Yes. A broken spring leaves your door inoperable and your garage unsecured. It also puts stress on the opener motor. Contact a professional immediately rather than trying to force the door open or closed.
