How Often Should You Pressure Wash Your Home in South Florida?

Residential
Written By Christopher Fernandez

If you live in Miami-Dade, Broward or Palm Beach, you've seen it: a house that looked spotless in spring has green streaks on the north wall by fall. Our heat, humidity and summer rain make South Florida one of the fastest places in the country for mold, mildew and algae to grow on outdoor surfaces.

So how often should you clean? Here's a practical schedule, surface by surface.

Exterior walls: once a year

Stucco, siding and painted block hold moisture, especially on shaded sides. A yearly soft wash removes mildew before it stains the paint and keeps your home looking cared-for. Homes near the water or under heavy tree cover may need it every 8–10 months.

Roof: every 1–2 years

Those black streaks on tile and shingle roofs are algae feeding on the roof surface. Left alone, they spread and hold moisture against the roof. Roofs should be soft washed with low pressure, never blasted, to protect tiles and shingles.

Driveways, walkways and sidewalks: once a year

Concrete and pavers turn dark and slippery as mold, oil and tire marks build up. A yearly cleaning restores the color and makes surfaces safer to walk on, especially after the rainy season.

Pool decks and patios: every 6–12 months

Pool decks get sunscreen, chlorine, leaves and constant foot traffic. Pavers and textured coatings trap grime, and wet algae is a slip risk. Twice a year keeps them bright and safe.

Fences, screens and outdoor furniture: as needed

Wood and vinyl fences, pool screens and lanai frames collect pollen and mildew. A light wash whenever you see buildup keeps them from staining.

Signs it's time now

  • Green, black or gray streaks on walls or the roof

  • Driveway or walkway darker than when it was new

  • Slippery spots on the pool deck or entry steps

  • An HOA notice about exterior appearance

  • You're getting ready to sell, host guests or welcome family for the holidays

Why the right method matters

More pressure is not always better. High pressure can etch concrete, strip paint, crack roof tiles and force water behind siding. Professionals match the method to the surface: soft washing with low pressure for roofs and walls, and controlled pressure with surface cleaners for concrete and pavers.
