Pressure Washing in Naples & Southwest Florida

Most owners wash driveways, walkways, and pool decks about once a year, and house exteriors every year or two; north-facing and heavily shaded surfaces green up faster. Roofs run on a longer cycle — a proper soft wash typically holds for several years. If your community sends compliance letters, that letter effectively sets your schedule. Coastal humidity, tree cover, irrigation overspray, and whether surfaces were sealed all move the interval.

High pressure isn't — it strips the tile surface, cracks tiles under foot traffic, and can void roof warranties. The accepted method is soft washing: a low-pressure application of a chlorine-based cleaning solution that kills the algae and bacteria causing black streaks, then a controlled rinse. Done right, the roof stays cleaner longer than a blasted roof, because the growth is killed rather than shaved. Ask any roof-cleaning crew to describe their method and plant-protection steps first.

Usually one of three things. The growth was shaved off, not killed — pressure without a cleaning agent leaves spores that regrow in months. Or the stain was never organic: irrigation rust and fertilizer stains need specific treatments. Or the surface is simply high-exposure — shaded, damp, near dense landscaping — where regrowth is fast no matter what. Sealing pavers and concrete after cleaning slows the cycle; so does fixing irrigation heads that spray the hardscape.

It varies with square footage and surface count, the method (soft-wash chemicals cost more to apply than plain pressure), roof pitch and height, how heavy the growth is, and add-ons like re-sanding, sealing, rust treatment, or gutter brightening. Access matters too — lanai interiors and screen enclosures are slow, fiddly work. Get per-surface line items rather than a lump sum so you can compare quotes and drop items you don't need.
