How much do professionals charge to pressure wash a deck?

Professional deck washing typically costs $150–$400 depending on size, material, and condition, generally working out to $0.30–$0.75 per square foot. Wood decks usually cost more than composite, since wood requires more careful pressure control to avoid splintering or raising the grain, along with additional time for mildew or algae treatment. Composite decks, particularly newer shell-technology products, often need lower pressure and less aggressive treatment, which can slightly reduce labor time. Staining or sealing afterward is typically quoted separately and can add $200–$500 depending on deck size. As with most exterior cleaning services, a specific walkthrough or detailed photos will produce a far more accurate quote than square footage alone, since surface condition affects labor time more than raw size does.
