Most pressure washing advice online assumes a mild, dry climate. South Florida is neither. Our heat and year-round humidity grow algae faster than almost anywhere in the country, so the cleaning cycle here is shorter. Here is a realistic schedule by surface.
Roofs and walls: every one to two years
The black streaks on roofs and the green on shaded walls are algae. Soft washed properly, a roof or wall stays clean one to two years here. Shaded, north-facing, and coastal surfaces land at the shorter end, because they stay damp longer.
Driveways and walkways: about once a year
Concrete greens up and stains over a year of rain, traffic, and organic debris. An annual pressure wash keeps it from setting into deep stains. Properties under heavy tree cover may want it twice a year.
Pool decks and patios: every six to twelve months
This is the surface that needs the most attention. Splash-out keeps it wet, screen enclosures keep it shaded, and foot traffic grinds in the growth. A slick, algae-covered deck is a genuine safety hazard around a pool, so this one is worth staying ahead of.
Screen enclosures: with the deck
Enclosure frames and screens collect the most grime and look worse from the street than from inside. Cleaning them on the same visit as the deck keeps the whole pool area consistent.
Why a schedule beats waiting
Letting a property go until it looks bad means paying for a heavy restoration clean every time. Staying on a cycle keeps every visit light, which costs less over the year and keeps the house looking right the whole time. That is the idea behind a recurring plan: the property never gets bad enough to need the expensive version.
Common Questions
How often should I pressure wash in Miami?
Driveways and walkways roughly once a year, pool decks every six to twelve months, and roofs and walls on a one-to-two-year cycle, sooner for shaded or coastal properties. South Florida's heat and humidity push these intervals shorter than the national average.
Is it cheaper to clean on a schedule?
Yes, over time. Staying on a schedule keeps surfaces from reaching the heavy-growth stage, so each visit is a light maintenance clean rather than an expensive restoration.
Which surface needs cleaning most often?
Usually the pool deck, because splash-out, shade, and foot traffic combine to grow algae fast, and a slick deck is a safety issue, not just a looks one.
