When a spring snaps, the first question is usually “did I do something wrong?” Almost always, no — springs are wear items with a built-in lifespan. But a few things do make them fail sooner, and most of those you can control. Here is what actually breaks garage door springs.
1. Normal wear (the big one)
Springs are rated in cycles — one cycle is the door going up and back down. A standard spring is good for around 10,000 cycles. If you run the door four to six times a day, that works out to roughly 7 to 12 years before metal fatigue catches up and it snaps. This is by far the most common cause, and it is not a defect — it is just the spring reaching the end of its life. More on that in how long springs last.
2. Rust and corrosion
Rust eats into the metal and creates weak points, and it also adds friction that makes the spring work harder every cycle. In our humidity, and especially in garages near sprinklers or with poor drainage, springs can rust faster than you would expect. A light coat of lubricant twice a year is the cheap defense.
3. Cold snaps
Metal gets more brittle in the cold, which is why so many springs let go on the first freezing morning of a North Texas winter. The spring was already near the end of its life; the sudden cold is just the final straw. If yours breaks in January, this is usually why.
4. Poor maintenance
Skipped lubrication is the most preventable cause. A dry, gritty spring grinds against itself and wears out early. So does an unbalanced door — if the door is heavy or dragging on worn rollers or bent tracks, the springs strain harder on every cycle. Keeping the whole door tuned protects the springs.
5. Wrong-sized or single springs
Springs must match the door's weight. An undersized spring — or a single spring on a heavy door that really needs two — is overworked from day one and fails early. This is a common issue with builder-grade or DIY installs. It is also why we always size springs to your specific door.
How to make your springs last longer
- Lubricate the springs and hardware twice a year.
- Keep the door balanced — fix worn rollers, cables, and tracks promptly.
- Replace both springs together on a two-spring door so they wear evenly (here is why that matters).
- Use correctly sized, higher-cycle springs when you replace them.
When a spring does go — and eventually one will — we replace them safely across DFW and size them right so the next set lasts.
Key takeaways
- Normal cycle wear is the main cause — ~10,000 cycles, roughly 7 to 12 years.
- Rust adds weak points and friction; twice-a-year lube is the cheap defense.
- Cold snaps make brittle, worn springs snap — common on the first freeze.
- An unbalanced door or worn rollers overwork the springs.
- Wrong-sized or single springs on a heavy door fail early — size them right.
