There's no fixed calendar interval — it's driven by what's actually growing on the house. Green or black streaking, moss in shaded corners, and mineral staining under sprinkler heads are the signals it's time, not a set number of months. Homes with heavy tree cover or sprinkler contact need attention sooner than homes in open sun.
What are the actual warning signs?
Look at the north-facing or shaded walls first — that's usually where growth shows up earliest.
- Green or black streaking on siding or stucco
- Dark spots or a slick film on roof shingles
- Moss or algae in corners that don't get direct sun
- Orange or brown rings under sprinkler heads and downspouts
- A driveway that looks a shade darker than the rest of the concrete
Why do some houses in the same neighborhood need it more often?
Shade, irrigation, and airflow matter more than the calendar. A house with mature trees overhead stays damp longer after rain, which is exactly what algae and mildew need. A yard where the sprinklers hit the siding or a fence line every morning is feeding the same growth on a schedule, whether anyone notices or not. Florida's humidity keeps all of this active for most of the year, so it's rarely a case of washing once and being done.
What if I wait too long?
Algae and mildew left in place long enough can etch into porous surfaces like unsealed stucco or older concrete, leaving a stain a normal cleaning won't fully lift. At that point it's not just a longer job — it may need a different treatment altogether.
How does Fort Lauderdale Pressure Washing figure out the right schedule for a specific house?
The crew, based out of Wilton Manors, looks at the property rather than defaulting to a set interval. Across the 20 communities it serves, tree cover and sun exposure vary enough house to house that two homes on the same street can end up on genuinely different schedules.
Does pressure washing prevent mold from coming back?
Pressure alone rinses growth off the surface but doesn't kill it at the root, so it tends to return. Soft washing, which uses a cleaning solution at low pressure, slows the regrowth more effectively — especially on roofs and siding.
Should the roof and the driveway be cleaned on the same schedule?
Not usually. Driveways collect physical dirt and tire marks that build up with use, while roofs mainly deal with biological growth that spreads on its own timeline. They often end up needing attention at different intervals.
I've never had my house pressure washed — where do I start?
Start with an assessment rather than guessing at a schedule. Fort Lauderdale Pressure Washing can look at the current buildup and tell you what actually needs attention now versus what can wait.
