Most homes benefit from pressure washing once a year to remove dirt, mold, mildew, and algae buildup. However, if you live in a humid or wooded area, you may need it twice a year to prevent excessive growth on surfaces.

Not all surfaces can handle high-pressure washing. Delicate materials like vinyl siding, roofs, and wood decks should be soft washed instead, using low pressure and special cleaning solutions to prevent damage. Harder surfaces like concrete driveways, brick, and stone can typically withstand high pressure.

Pressure washing uses high-pressure water to clean tough surfaces like driveways and sidewalks. Soft washing uses lower pressure and specialized cleaning solutions to safely clean roofs, siding, and other delicate materials without causing damage.
