How Often Should You Pressure Wash in South Florida?

In most of the country, once a year is standard. In South Florida, the combination of humidity, heat, salt air (especially within 10 miles of the coast), and the rainy season means organic growth — mold, mildew, algae — can return within 3–6 months.

Most exterior cleaning professionals recommend twice a year for driveways and walkways in this climate, and once a year for pool decks and patios. Roofs and driveways in shaded areas (under trees) may need more frequent attention.

A soft wash treatment with a post-clean biocide can extend the clean significantly, sometimes doubling the time before regrowth becomes visible.

The cost of bi-annual cleaning is almost always less than the cost of HOA fines or surface remediation from years of buildup.
