How long do garage door springs last?
A standard torsion spring is rated for about 10,000 open-and-close cycles, which works out to roughly seven years for a household that uses the door four times a day. On a hurricane-rated Miami-Dade door, expect less: the panels are heavier, and weight is what consumes cycles.
How springs are actually rated
Cycles, not years
one open plus one close is one cycle

four cycles a day is a common household

How long springs last at your usage
| Situation | What it means | Timing | Next step |
|---|---|---|---|
| Two cycles a day | One car, occasional trips | Around a decade on a standard spring | Still worth an annual look |
| Four cycles a day | The common Miami household | Roughly seven years | Plan for it rather than be surprised |
| Six or more cycles a day | Two drivers, a teenager, deliveries | Four to five years | A high-cycle spring pays for itself |
| Within a few miles of the water | Salt reaches the wire and pits it | Take years off the estimate | Coated wire is the sensible upgrade |
| A visible gap in the coil | The spring has already failed | Now | Do not operate the door |
| One spring broke on a two-spring door | The second has the same hours on it | Replace both in the same visit | The second call costs more than the second spring |
Worth keeping vs. worth replacing
Normal
Sound spring, clean wire
Tight coils, an even coating and no gap: a spring with life left in it.
Warning
Pitted and rust-bloomed
Once corrosion reaches the wire, the cycle count on the box no longer applies.

More detail if you want it
A cycle is one trip up and one trip down
Manufacturers rate springs by cycle count because that is the only honest unit. A holiday home used twice a month and a family of five with two drivers will wear the same spring out on completely different timetables. Count your own: leaving for work and coming back is two cycles, and a teenager with a bicycle can quietly double the household total.
Higher-cycle springs exist and cost more up front. On a door that gets heavy daily use, the arithmetic usually favors paying once for a 25,000-cycle spring instead of twice for a 10,000-cycle one, plus a second call-out.
Why Miami-Dade doors are harder on springs
A door approved for the High-Velocity Hurricane Zone is built to resist suction pulling it outward, and that means thicker steel, internal struts and reinforced hardware. All of it adds mass, and the spring is what carries that mass every single time the door moves. Two identical households, one with a pre-code door and one with an approved replacement, will not get the same lifespan out of the same spring.
Salt air adds a second, slower problem. Coastal humidity corrodes the wire from the outside in, and a corroded spring fails below its rated count without warning. Homes closest to Biscayne Bay see this first.
The warnings you get before it breaks
A tired spring announces itself. The door feels heavier by hand, it drifts back down instead of holding halfway, it jerks on the way up, or the opener strains and reverses. Look at the coil itself: gaps that have opened up along the winding, visible rust, or a coil that no longer sits flush all point the same way.
When one of a pair breaks, the other is the same age and has done the same work. Replacing only the broken one leaves an unbalanced system that puts uneven load on the opener and shortens the life of the new spring.
| Work | Typical range | What moves the price | |
|---|---|---|---|
| Torsion spring replacement (pair) | $250 – $450 | Higher than extension springs: winding bars are required and the job carries real injury risk. Always replaced in pairs. | Book this — Torsion spring replacement (pair) |
| Extension spring replacement | $200 – $330 | Less common on Miami-Dade doors: hurricane-rated panels are heavier and usually call for torsion. | Book this — Extension spring replacement |

Garage door spring life: what owners ask most
Can one garage door spring be replaced and the other left in place?
Replacing one torsion spring and keeping the other is possible, and it is a false economy on a pair that has carried the same load since day one.
- The survivor is close to its own cycle limit
- A mismatched pair pushes the load onto the motor
- The new spring wears faster beside a tired one
Is a broken garage door spring an emergency?
A broken garage door spring is not dangerous while the door stays closed, but the door must not keep being operated.
- The opener then carries the whole panel weight
- It was never designed to do that
- Forcing it turns one bill into two
Do hurricane-rated garage doors need special springs?
A hurricane-rated door needs springs matched to its actual weight, which is normally higher than on a door built before the current requirements.
- Sized from door weight, drum type and track radius
- Specified for that door, not picked off a shelf
- Heavier panels spend cycles faster
How long does a garage door spring replacement take?
A straightforward pair swap on a residential garage door is usually under two hours, balancing and opener re-test included.
- Balancing the door by hand before finishing
- Re-testing the opener's force settings
- Unusual drums or a converted system take longer

Not sure which part failed?
Most garage door faults are identifiable from the noise and the way the door moves. Start there — it usually costs less than you expect.
