The charts in this form depict the predicted life expectancies of different appliances, products, materials, systems, and components in a home.

Note: These life expectancies have been determined through thorough research and testing based on regular recommended maintenance and conditions of normal wear and tear. Extreme weather, neglect, overuse, or abuse, and/or any other conditions were not under consideration upon the creation of this chart. Therefore, this chart should only be used as a general guideline, and not relied upon as a guarantee or warranty.
