Best Time of Year to Pressure Wash Your Jacksonville Home

Late Fall Through Winter (November – February)

This is generally the best window to get ahead of buildup rather than chase it. Rainfall drops off, humidity is lower than the rest of the year, and surfaces have more time to fully dry between any rain that does fall — all of which slows down new algae and mold growth. Cleaning during this window also sets your property up clean heading into spring pollen season.

Spring (March – May)

Oak and pine pollen coats driveways, cars, and siding in a fine yellow film almost overnight — the single most common ‘why does my driveway look like this’ call of the year. A cleaning timed for late spring, after peak pollen has passed, clears that film along with whatever algae growth built up over the winter.

Summer (June – September)

This is Jacksonville’s rainy season, with August alone averaging roughly 7.6 inches of rain across about 19 rainy days. Constant moisture is exactly what algae and mold need to spread, and it spreads fastest in shaded spots and north-facing walls that never fully dry out. It’s also hurricane season, so summer cleaning often overlaps with pre-storm gutter clearing and roof checks rather than routine washing alone.

Early Fall (September – October)

Right after peak hurricane risk and rainy season, early fall is a good window for post-storm cleanup if a storm has passed through, or for addressing the algae and mold growth that built up over the humid summer months before it gets worse heading into the next cycle.
