Quote by surface, schedule by route and keep proof of every clean.

Pressure washing looks simple from the road. Behind it sit surface measurements, detergent mixes, water supply, wastewater rules, weather and a crew that has to be in the right street at the right hour.

Most companies run this from a booking form, a calendar, a notes app and a phone gallery. Quotes are guessed, repeat customers are forgotten, and the proof of a finished job is hard to find when a customer disputes it.

Someone calls wanting a driveway, deck, shopfront, car park or vehicle fleet washed. The office takes the address, the surface type and an approximate area, then quotes from a rate per surface. Some jobs need soft washing with detergent, others need hot water or a surface cleaner. Weather moves the day often, so a booked slot is rarely fixed.

Crews load the trailer with machines, hoses, chemicals and fuel, and drive a route of several stops. At each stop they take a before photograph, wash, rinse and take an after photograph. Wastewater is handled as local rules require. Back at the office, the job is invoiced, and the machine hours and detergent used are written down, if at all. Commercial clients ask for the same site every month. Those visits are easy to lose.
