InterNACHI's Estimated Life Expectancy
				  Chart
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.

Appliance life expectancy depends to a great extent on the
				  use it receives. Furthermore, consumers often replace appliances long before
				  they become worn out due to changes in styling, technology and consumer
				  preferences. Of a home's major appliances, gas ranges have the longest life
				  expectancy.

Kitchens are in the process of becoming larger and more

				  "great room."
Great rooms are a place to cook as well as a space where
				  people gather to read, talk, eat, do homework, surf the Internet, and pay
				  bills.

				  years, but if it cracks it is immediately damaged.

				  has a lifespan of 25 years. Polyvinyl fences are designed to last as long as
				  the house, and asphalt driveways should last between 15 and 20 years. Tennis
				  courts can last a lifetime if they are recoated; most coatings last 12 to 15
				  years. The concrete shell of a swimming pool is expected to last more than 25
				  years, but the interior plaster and tile have life expectancies of about 10 to

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
