"How long will it last?" is the first question we hear about new doors - and the honest answer is that a garage door isn't one component, it's a system. Each part ages on its own schedule.
The door itself: 15–30 years
A quality steel door lasts 15–30 years depending on climate, use, and maintenance. Insulated steel doors from brands like DoorLink, Ankmar, and Amarr sit at the top of that range; builder-grade uninsulated doors at the bottom.
Springs: 7–10 years
Springs are rated in cycles, not years - typically 10,000 cycles, which is 7–10 years at 3–4 uses a day. High-cycle springs (25,000+) cost a little more and last two to three times longer, the best upgrade-per-dollar on any door.
The opener: 10–15 years
Openers usually give 10–15 years of service. If yours predates 1993 it lacks legally required safety sensors and should be replaced regardless of whether it still runs.
Rollers, cables, and hardware: 5–10 years
Nylon rollers last 5–7 years, cables and pulleys closer to 8–10. These are inexpensive parts whose failure causes expensive damage - which is why they're checked at every tune-up.
How to stretch every lifespan
- Lubricate springs, rollers, and hinges twice a year
- Test door balance annually - an unbalanced door wears everything faster
- Fix small issues (noise, jerky travel) before they cascade
- Book a professional multi-point inspection once a year
