How Long Does Exterior Concrete Like Stairs Typically Last

Concrete may seem indestructible, but like anything exposed to the elements, it has a lifespan. When it comes to exterior concrete structures like stairs, the general expectation is a service life of 15 to 20 years—but this range is far from fixed. What truly determines how long your concrete lasts is how well it was mixed, installed, and maintained.

Concrete Longevity Depends on the Mix and the Method

The durability of exterior concrete begins at the source: the mix. If the ratio of water to cement isn’t correct, or if the aggregate isn’t evenly distributed, concrete becomes prone to cracking, scaling, and surface erosion far sooner than it should.

Just as important is the installation. Concrete should be poured and worked properly—a process that helps eliminate surface voids and ensures better compaction and finish. When stairs or walkways are installed by amateurs or with makeshift mixing, the structure is at risk from day one. It might look solid, but underlying flaws may emerge as early as the first freeze-thaw cycle.
