How long does paint on a house last?

Exterior paint can be expected to last 7 to 10 years, and interior paint 10 to 15+ years. But it is possible for a paint finish to fall short of even the low end of these ranges due to any of the following factors:

• Inadequate surface prep and cleaning
• Severe temperature and moisture fluctuations
• Moisture buildup behind the walls
• Painting new construction without a primer coat
• Low quality paint

    Inadequate surface prep is most often the culprit when a paint surface fails before its normal life expectancy.  Also, see our blog posts What causes paint to peel prematurely on the exterior of a house? and How can I tell when it's time to paint the house?

    Go to our blog post What is the average lifespan of the parts of a house? for rating of other house components. To understand the basis, potential use, and limitations of lifespan ratings, see our blog post How accurate are the average life expectancy ratings of home components? Are they actually useful?
