What is the average life expectancy of concrete or steel exterior stairs or steps?
Monday, June 8, 2020
You can expect concrete or steel exterior stairs or steps to last 50 to 80 years, with an average of 65 years. Weather deteriorates the concrete surface, and spalling due to reinforcing bar corrosion cracks the concrete over time. See our blog post What is concrete spalling? to learn more. The nemesis of steel stairs is simple rust, which can be slowed by maintaining a coating over all surfaces.
Here’s a bar graph comparing concrete or steel stairs life expectancy to other types of home steps and stairs.

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMae, and our own professional experience. Because of the numerous variables that can affect a lifespan, they should be used as rough guidelines only, and not relied upon as a warranty or guarantee of future performance.
