What is the average life expectancy of interior stairs or steps?
Monday, June 8, 2020
You can expect interior stairs or steps to last the life of a home, 100 years or more. This includes manufactured and spiral metal stairs. Most stairs are wood and moisture intrusion or termites will shorten the stair lifespan. Regular maintenance, which includes repairing or replacing damaged, loose, or badly worn components, is necessary as a stair ages.

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMae, and our own professional experience.
