How Much Does Pressure Washing Cost?
Estimate pressure washing service cost per square foot — with the free calculator.
Pressure washing lifts years of grime off driveways, patios and siding — and protects surfaces from mold and mildew damage. This guide covers the price per square foot and a calculator.
THE SHORT ANSWER
The short answer
Pressure washing runs $0.08–$0.55 per sq ft. A driveway costs $175–$320; house washing runs $250–$600. Most homes get a full wash for $300–$800 depending on size and surfaces.
What it costs per surface
Driveways run $0.30-$0.55 per sq ft; house siding $0.15-$0.50; patios and decks $0.25-$0.50. Heavy grime, oil stains and multi-story work add time and cost. Minimums of $75-$150 are common for small jobs.

- Full property: $300–$800
Soft washing vs pressure
Houses and roofs should be soft-washed with low pressure and cleaning solution — high pressure can etch wood or force water behind siding. Driveways and concrete can take full pressure. Ask which method the pro uses.
When to wash
Once a year in spring removes winter grime and mildew before it stains. Concrete and pavers may need a second pass for oil. Clean gutters and downspouts at the same time for a full exterior reset.
