Florida homes often develop exterior buildup faster than homes in drier climates. Humidity, frequent rain, shade, pollen, insects and nearby trees can all contribute to mildew, algae and dirt on siding, soffits, concrete, decks and fences. There is no single schedule that fits every property, but regular exterior cleaning can keep buildup from becoming harder to remove.
A practical cleaning schedule
Many homeowners look at exterior cleaning once or twice a year, but the right timing depends on the property. A shaded home near trees may need attention more often than a sunny home with good airflow. North-facing walls and damp areas often show green or dark growth first.
Instead of cleaning strictly by the calendar, inspect the exterior every few months and schedule cleaning when buildup becomes noticeable.
Pressure washing vs. soft washing
Not every surface should receive the same pressure. Concrete and some masonry can tolerate stronger cleaning methods, while painted siding, stucco, roofs, screens and delicate materials may need lower-pressure or soft-wash techniques.
Using too much pressure can force water behind siding, damage paint, scar wood, strip mortar or leave visible marks. The surface and condition should determine the method.
Areas homeowners often overlook
Driveways and sidewalks are obvious, but soffits, fascia, porch ceilings, fence lines, pool-area concrete, sheds and the shaded side of a home can collect significant buildup. Cleaning several related areas during the same visit can create a more consistent appearance.
If exterior painting is planned, cleaning and allowing the surface to dry can also be an important preparation step.
Ways to keep the exterior cleaner longer
Trim vegetation away from walls where practical, keep gutters flowing, improve drainage around persistently damp areas and address irrigation that sprays siding or fences. These steps do not eliminate Florida humidity, but they can reduce the conditions that encourage recurring growth.

Frequently Asked Questions
Is pressure washing safe for painted siding?
It can be when the right method and pressure are used. Delicate or painted surfaces may be better suited to lower-pressure cleaning.
Why does green algae keep returning?
Shade, moisture, humidity and nearby vegetation create conditions where organic growth returns. Improving airflow and reducing persistent moisture can help.
Should I pressure wash before exterior painting?
Cleaning is often an important preparation step because paint adheres better to a clean, sound surface. The surface should also be allowed to dry properly.
Can concrete and siding be cleaned the same way?
Not necessarily. Concrete often tolerates more pressure than siding, painted surfaces, wood or stucco.
