In Orlando, concrete never really dries out. Summer rain, morning dew, and shade from oaks and palms give mildew and algae everything they need to grow, which is why driveways go from light gray to streaked black in a single season.
For most homes, a once-a-year pressure wash keeps a driveway looking good. Shaded driveways, north-facing walkways, and pool decks usually need it twice a year, and paver driveways often benefit from a cleaning before resealing.
Pressure matters as much as frequency. Too much pressure can etch concrete, leave wand marks, or blow the sand out of paver joints. We match the pressure and nozzle to the surface and pre-treat mildew so it lifts without forcing it.
If you're already booking a bin clean, adding a driveway or sidewalk wash to the same visit is the easiest way to keep the whole front of the house looking cared for.
