How Often Should You Pressure Wash Your House in Jacksonville?

The General Rule

Most Jacksonville homes do well with a full exterior wash once a year. That’s enough to stay ahead of algae and mold growth for most standard, sun-exposed lots without over-cleaning a home that doesn’t need it yet.

When Once a Year Isn’t Enough

Certain conditions push that timeline down to every 6 to 12 months instead:

• Homes under heavy live oak or pine canopy that stays shaded most of the day
• Properties within a few miles of the coast dealing with salt air on top of standard algae and mold
• North-facing walls that rarely get direct sun to dry them out
• Homes near lawns with heavy irrigation overspray hitting the siding directly

Signs You’re Overdue, Regardless of the Calendar

Rather than tracking months, watch for the signs themselves: dark streaking starting to show on the roofline, a chalky or dull look replacing what used to be a brighter color, or green film forming in shaded corners. These show up before the buildup is obvious from the street, and catching it early means a shorter, less intensive cleaning.
