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.
What the standards say about garage door springs
A garage door torsion spring has a measurable life rating. The industry minimum is 10,000 cycles — one cycle is a single open plus close — and high-cycle springs are sold at roughly 27,000 and 54,000 cycles for doors that get heavy daily use.
- 10,000 cycles is the industry-minimum rating for a torsion spring. DDM Garage Doors
- High-cycle springs are catalogued at about 27,000 and 54,000 cycles; they use thicker, longer wire so each trip carries less stress. DDM Garage Doors
- Spring life in years is simple arithmetic: rating ÷ (daily cycles × 365). At four open/close trips a day, a 10,000-cycle spring lasts about 7 years; a 27,000-cycle spring about 18.
- DASMA lists why springs wear out: metal fatigue from cycling, rust that eats into the wire, a door made heavier than spec, a bad install, harsh climate and skipped lubrication. DASMA TDS-190
| Spring rating (cycles) | Wire / stress | ~Years at 3/day | ~Years at 4/day |
|---|---|---|---|
| 10,000 (industry minimum) | Standard wire | ~9 | ~7 |
| 27,000 (high-cycle) | Thicker, longer wire | ~25 | ~18 |
| 54,000 (high-cycle) | Heaviest wire | ~49 | ~37 |
“Regular greasing or lubrication of springs, as required in the manufacturer’s instructions, will help to maximize spring cycle life.”
DASMA specifically names extreme climate as a factor that shortens spring life. In DFW, springs live through 100°F-plus summers and the occasional hard freeze, and that repeated expansion and contraction is exactly the kind of metal fatigue the standard describes. A little spray lubricant twice a year is the cheapest defense.

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.
