Most homes should be power washed once every 12–18 months, but the ideal frequency depends on climate, surface materials, surrounding vegetation, and the homeowner’s desired appearance standards. In humid, rainy, dusty, or high-pollution regions, many homeowners schedule cleaning every 6–12 months to prevent mold, algae, and grime from building up.
Professionals listed in the PowerWashing.com Directory typically evaluate a home’s environment and recommend a cleaning schedule tailored to long-term protection and curb appeal.

⭐ 2. Regions That Require More Frequent Washing
Your location plays a major role. Homes should be washed more frequently in areas with:

Urban or industrial regions
Pollution, soot, and vehicle emissions cling to exterior surfaces.
In these environments, many contractors recommend every 6–12 months instead of yearly.

Every 2–4 years, depending on algae growth.
Driveways & Concrete
Every 6–12 months, or more often for high-traffic homes.
Wood Decks & Fences
Every 12–24 months, depending on weather exposure and whether the wood is sealed.

Pool Decks
Every 3–6 months in humid areas or if exposed to sunscreen, algae, or calcium buildup.
