How Long Will My Home Systems and Components Typically Last?

A well-built home can last for hundreds of years, but many of its parts must be replaced or removed regularly.

Here's a sampling of average life expectancy in years for different products and materials used in the home, as listed in a report titled "1997 Housing Facts, Figures and Trends" published by the National Association of Home Builders (NAHB) based in Washington, D.C. These are estimates only. I am making no guarantees or promises.

The number following the item is in years.
