Power Washing Cost Calculator

Knowing what professional power washing should cost makes it far easier to plan home or commercial property upkeep for 2026, a year in which labor and equipment have edged up by a modest 3-5% over recent figures. A solid estimate up front keeps the project on budget and heads off surprise charges.

The math runs on a tiered model driven by surface type and square footage, mirroring how the industry actually prices jobs. Every surface, whether concrete, siding, or decking, carries a base per-square-foot rate that drops as the total area grows. Concrete, for example, might run $0.25/sq ft under 1,000 sq ft, fall to $0.20/sq ft across the 1,001-2,500 sq ft range, and settle at $0.18/sq ft past 2,500 sq ft, with comparable volume breaks on other materials.

Where you live, how stubborn the grime is, how reachable the surfaces are, and extras like stain removal or sealing all nudge the real price away from the estimate. Measure the area carefully, since lowballing the square footage is a frequent source of error. Note too that many companies set a minimum service fee, which this tool does not build in, so confirm that detail with your provider.
