How Long Does a Garage Door Spring Last?

June 14, 2024

Garage door springs don't wear out on a calendar — they wear out in cycles. A standard spring is generally built for around 10,000 open-and-close cycles, which works out to roughly 7 to 12 years for a household that opens the garage a handful of times a day. Use it more, and the spring gets there faster.

Why Cycles Matter More Than Years

One "cycle" is one full open-and-close. A family that treats the garage as their main entrance — kids leaving for school, multiple drivers, deliveries — can burn through cycles two or three times faster than a garage that's used once or twice a day. That's why two identical springs installed the same year can fail years apart. If your door sees heavy daily use, a higher-cycle spring costs a bit more upfront but spreads that cost out over a lot more years.

What Shortens Spring Life in Phoenix

Heat is hard on metal. Summer temperatures in the garage can sit well above what the spring sees in a milder climate, and that constant heat-cool cycling speeds up metal fatigue over time. Dust and lack of lubrication add to it — a dry, gritty spring works harder than one that's properly maintained, which shortens its usable life.

Signs Your Spring Is Near the End

• ✓A loud bang from the garage — that's usually the sound of a torsion spring letting go
• ✓A visible gap in the coil where the spring has separated
• ✓The door only lifts a few inches, or the opener strains and stalls
• ✓The top panel of the door bows or bends slightly when it tries to open
• ✓The door drops or closes faster than it used to
• ✓Cables look loose or slack around the bottom rollers

Should You Replace Both Springs at Once?

If your door runs on a matched pair and one has failed, it's worth replacing both. They were installed at the same time and have gone through the same number of cycles, so the second one is usually not far behind. Replacing just one saves a little money today but often means paying for a second service call within a year or two.

Getting More Life Out of Your Springs

• ✓Lubricate the springs, rollers, and hinges roughly twice a year — a light garage door lubricant, not WD-40
• ✓Keep the door balanced — if it feels heavy or uneven when moved by hand, have it checked before it strains the springs
• ✓Don't leave the door open for long stretches in extreme heat if you can help it
• ✓Have the door looked at periodically rather than waiting for something to fail

None of that makes a spring last forever, but it keeps it from failing before its time. When a spring does go, replacement isn't a DIY job — the tension involved can cause serious injury if you don't have the right tools and training.
