One company quotes $199, another quotes $650, and both are pointing at the same house — usually because they're quoting different scopes. This calculator uses the published market ranges from our Toms River power washing cost guide, so you can anchor a budget before collecting written quotes: house washes $250–$700 for most homes, driveways $120–$400, decks $120–$500, roof soft washes $250–$950.
Coastal Ocean County homes fight algae and salt film harder than most of New Jersey, and the method matters as much as the price: siding and roofs get low-pressure soft washing (shingle manufacturers explicitly warn against pressure on asphalt roofs), while concrete takes real pressure through surface cleaners. A quote far below these ranges is usually a water-only blast that leaves the algae alive.

This is a planning estimate, not a quote. Every job differs — your real number comes from a free written quote.
Roof work is no-pressure soft washing — $0.20–$0.70 per square foot in the current NJ market — because pressure strips shingle granules. The black streaks are a bacteria; the solution kills it on contact and rain finishes the rinse.
They're real prices for a different service: a fast blast with plain water, no detergents, no insurance overhead. It strips nothing organic and the green comes back by fall. Our guide's red-flag section decodes the playbook.
Almost always — the setup, hoses, and travel are already paid for once the crew is on site. House + driveway, or house + roof, typically beats the two line items priced separately. Ask for the combined number in writing.
