General Lifespan
A well-prepped exterior paint job with quality, sun-rated product typically lasts 7–10 years on sun-exposed walls in the Sacramento area. South- and west-facing walls fade and fail first; north-facing and shaded walls last longer.
What Shortens the Life
› Poor prep — paint over peeling or chalky surfaces fails fast
› Low-quality or non-UV-rated paint
› Unresolved moisture causing peeling
› No primer on bare or repaired areas
What Extends the Life
Thorough prep, a quality sun-rated product, the right primer, and proper dry conditions during application. The homes whose paint lasts longest are the ones where prep was done right the last time.
