A power washing estimate is built by the square foot, and the mistake most crews make is pricing the house as one number. Siding, flatwork and roofs wash at different rates because they take different time, different pressure and different chemicals, so the estimate should carry each surface at its own square footage and its own rate, with the setup and the chemicals on lines of their own. This page walks how pressure washing estimates are built from a take-off of the surfaces, works an example, and points at the free pressure washing estimate calculator on this site that prices siding and flatwork by the square foot from the crew's own rates. No figure on it is a market rate; every one is yours.
Take off the surfaces before you price anything
Siding is the wall area less the openings: a 40 by 30 foot single storey house at 10 feet to the eaves is 1,400 square feet of wall before doors and windows come off. Flatwork is measured flat: a 20 by 24 driveway is 480 square feet, a 12 by 16 patio 192. The estimate carries each surface separately, so the customer who drops the patio sees exactly what it saves and the crew knows what is on the job before the trailer is loaded.
A rate per square foot for each surface, and the lines that do not scale
Siding washes at one rate and flatwork at another, because the pressure, the chemicals and the time differ. The tool takes your rate for each, so 1,400 square feet of siding at your siding rate and 672 square feet of flatwork at your flatwork rate are two lines the customer can read. Setup, travel and chemicals are added as their own figures, because a small job still costs the trip and the mix.
The deposit and the price the customer signs
Power washing estimates usually ask for a deposit against the date, and the tool works it as your percentage of the total so the figure on the estimate is the one you collect. The total is the sum of the surface lines and the fixed lines; the tool shows it with the square footage beside it so a customer comparing crews by the foot can do the comparison from your own estimate rather than a guess.
Keeping the estimate against the customer
The free pressure washing estimate calculator prices the job on the page with no account. TakeoffDeck Pro saves every estimate against the customer and the address, brands it and sends it under your own name, so the annual wash starts from last year's take-off. This page publishes no rate for pressure washing; the rates are the crew's own.
Questions people ask about power washing estimate
How is a power washing estimate calculated?
Take off each surface in square feet, siding separately from flatwork, price each at your rate per square foot, add setup and chemicals as fixed lines, and ask for your deposit against the total. The tool works it from your figures.
Should pressure washing estimates be priced by the square foot or by the job?
By the square foot per surface, shown as a job total. The customer sees one price; the crew and the callback see the surfaces and the rates that made it.
Is the pressure washing estimate calculator free?
Yes, no account: enter the square feet of siding and flatwork, your rates, your setup and chemical figures and your deposit percentage, and it works the estimate on the page.
