The following chart details the predicted life expectancy of household materials and components. 
Interior and exterior paints can last for 15 years or longer, however homeowners often paint more frequently. Surface preparation is likely the most important determiner of paint life expectancy.

Note: Life expectancy varies with usage, weather, installation, maintenance and
quality of materials. Items listed as lasting 100+ years, especially those that open and close, often
fail prematurely due to misuse or overuse. This list should be used only as a general guideline, not
as a guarantee or warranty regarding the performance or life expectancy of any product.
