Pressure-washing exterior-area estimator

Measure the driveway, walkway, patio, deck, fence, and siding you plan to wash and add the square footage up in one place. The result is a scope aid for your own quote — not a price, a chemical or equipment plan, or a site inspection.

Measure each surface

Enter feet for the surfaces you plan to wash and leave the rest blank. Fences and siding use height as the second measurement.

This total is a scope aid built from your own measurements. It is not a price, a chemical or equipment plan, or a site inspection — you confirm the scope and set the price.

This is a browser-only estimator. Nothing you type is saved or sent.

How the area math works

The estimator multiplies and adds only the measurements you type. It has no per-square-foot rate, chemical or pressure guidance, or assumed surface condition.

Surface area
length (ft) × width or height (ft), per surface
Total area
sum of the measured surface areas, in sq ft
