Best Time of Year to Pressure Wash Your House in the Lowcountry
Hilton Head, Bluffton and Okatie homeowners deal with pollen in spring, algae all summer, and humidity nearly year-round. So when is the best time to wash your house? Here's a season-by-season breakdown for our coastal climate.
Spring: the most popular time to wash
By late spring, winter mold and a thick layer of yellow-green pollen have built up on siding, decks and walkways. Washing after the heaviest pollen drop (typically late April into May) resets your home for the season and clears the allergens clinging to your exterior. This is our busiest window, so book early.
Summer: stay ahead of algae
The Lowcountry's heat and humidity make summer prime time for green algae and black mold growth, especially on shaded north-facing walls. A mid-summer soft wash keeps growth from taking hold and your home looking sharp through the busy visitor season.
Fall: prep for the holidays
Early fall is ideal for clearing the summer's algae buildup before family visits and holiday gatherings. It's also a great time for roof cleaning and gutter clearing ahead of leaf season.
Winter: the easiest time to book
Because Hilton Head rarely freezes, soft washing and pressure washing run all winter long. Demand drops, so scheduling is easier and more flexible. Winter is a smart time to knock out driveways and any cleaning you put off during the busy months.
Bottom line: the best results come from washing twice a year — once in late spring after pollen, and once in early fall. Homes in heavy shade or near the marsh may benefit from a yearly maintenance plan to stay ahead of mold.
