Pressure washing costs in Phoenix

Dust is the dirt that matters on a Phoenix house. A 2016 National Weather Service study of the Sky Harbor records found that haboobs, the walls of dust pushed out ahead of summer thunderstorms, hit the airport two to three times a year. Their season peaks in late July and early August, and the average storm shows up around 6:30 in the evening. The same study found that 45 percent of those dust storms were followed by rain at the airport within an hour.

If you wash once a year, after the monsoon is a sensible time to book it. Stucco and painted walls want low pressure and a cleaner that does the work. A hard blast can chip the finish. Bare concrete can take more.

Think about where the rinse water lands. The City of Phoenix stormwater program puts it plainly: only stormwater belongs in the storm drain. It keeps a short list of other flows it allows, like lawn watering and a resident washing a car, and only when they aren't a source of significant pollutants. If your crew uses soap, ask where the runoff goes. Pressure washing isn't named anywhere on the city's list of allowed flows.
