The short answer
How long garage door springs last depends on how often you use the door. Standard torsion springs are commonly rated around 10,000 cycles, and for a typical household that works out to somewhere around seven to ten years. Heavy use shortens that. If your door is older than that and still on its original springs, it's worth having them looked at. Call me at (619) 930-7869 and I'll check them on a free estimate.
A cycle is one full open and one full close. So every time you leave in the morning and come home at night, that's two cycles. It adds up faster than people expect.
Doing the math for your door
If you don't know how old your springs are, there are a few clues. A house that's had the same owner for a decade or more, with no spring work done, is probably on original springs or close to it. Springs with a dull, rusty finish have usually been there a while. And if the door was installed along with the opener and the opener is old, the springs likely are too.
That's why two neighbors with the same door can have very different spring lives. If your family goes in and out through the garage all day, your springs are working much harder than the ones next door that open twice a day.
- 1Count your daily cyclesThink about a normal day. Leaving for work, coming home, a run to the store, the kids coming and going. Each open and close is one cycle.
- 2Multiply by 365Four cycles a day is about 1,460 cycles a year. Eight cycles a day, which is common in a busy house that uses the garage as the front door, is about 2,920.
- 3Divide the rating by your yearly numberA 10,000-cycle spring at four cycles a day lasts roughly seven years. At eight a day, it's closer to three and a half.
- 4Adjust for conditionsRust, an out-of-balance door, and a spring that was undersized for the door all bring that number down. The math gives you a ballpark, not a date.
What wears springs out faster
- RustRust pits the wire and adds friction between the coils. Garages near the coast and the bay see more of it from salt air.
- An unbalanced doorIf the door was never balanced right, or the springs have weakened unevenly, they work harder on every cycle.
- The wrong spring for the doorA spring that's undersized for the door's weight is stressed beyond its design and fails early. This is common after quick DIY or bargain repairs.
- Heavier doorsAdding insulation, windows or a new skin to a door adds weight. The springs need to be matched to the new weight.
- Friction elsewhereDry rollers, worn bearings and binding tracks make the whole system fight itself, and the springs take some of that load.
Signs your springs are near the end
Springs don't always give warning, but they often do. Look from the floor, without touching anything. A torsion spring with visible rust or coils that look stretched and spaced out is tired. A door that slams down harder than it used to, or rises unevenly, may be losing its balance. An opener that strains, slows down or stops partway up is often working against weak springs.
If you hear a loud bang and the door won't open, the spring already broke. My guide on signs of a broken spring covers that, and what to do in the meantime.
A worn spring is still a loaded spring. Never touch, adjust or try to replace it yourself. Look from a distance and call a licensed tech.
Spring quality and sizing
Not all springs are equal. I use better-quality springs than the bare-minimum ones a lot of doors come with from the builder, and I size each one to the door by measuring and weighing, not by grabbing whatever's close. A spring that's right for the door lasts longer and keeps the door balanced, which is easier on the opener too.
You may also hear about high-cycle springs, which use heavier wire and longer coils and carry a higher cycle rating. They exist across the industry. What I put on your door is a better-quality spring sized to it, and I balance the door so the springs share the load evenly. If you want to know what moves the price, my spring repair cost guide explains it without numbers, and the estimate itself is free.
On doors with two springs, I usually replace both at the same time. They've done the same number of cycles, and when one goes, the other is rarely far behind. Replacing both also keeps the lift even from side to side.
Springs past their prime?Spring repairHow to get more life out of them
Keep the door balanced and moving freely. A yearly garage door tune-up covers the balance check, lube on the springs and moving parts, and a look at the cables, drums and rollers. It's the simplest way to make sure your springs get close to their rated life instead of failing early.
If your door is on extension springs rather than torsion springs, the numbers are similar but they tend to show wear sooner. My guide on torsion vs. extension springs explains the difference. And if you're out near Mission Trails, I cover spring repair in San Carlos and Allied Gardens on the same schedule.
