How Often Should You Pressure Wash Your Home in Southern California?

Written By Shayne Johnson

Southern California’s climate is mild, but it quietly takes a toll on your home’s exterior. Dust, coastal salt, smog, pollen, and sprinkler runoff build up faster than most homeowners realize.

General recommendation:

  • House exterior: once per year

  • Driveways & sidewalks: 1–2 times per year

  • Roof cleaning: every 2–3 years

  • Patios & decks: annually, or as needed

Homes near the coast or high-traffic roads often need more frequent cleanings due to salt air and pollution. Regular pressure washing prevents permanent staining, mold growth, and surface deterioration—saving money on repairs long term.
