Pressure Washing Cost Per Square Foot | Pressure Washing Cost Guide

Q: How much is pressure washing per square foot?

Roughly $0.10–$0.60 per square foot depending on surface: concrete is $0.10–$0.25, siding $0.15–$0.30, decks $0.20–$0.45, and roofs $0.20–$0.60 (soft-washed). Heavier staining and harder access push toward the top of each range.

Q: Is pressure washing priced by the hour or by the job?

Reputable companies quote a flat price by the job, usually built from a per-square-foot rate after measuring the area. Hourly-only pricing with no cap is a red flag — ask for a not-to-exceed number.

Pressure Washing Cost Per Square Foot

Most exterior cleaning is priced by area. Here’s the per-square-foot rate by surface, and how pros turn it into a flat quote.

The short answer

Pressure washing runs roughly $0.10–$0.60 per square foot depending on the surface: concrete $0.10–$0.25, siding $0.15–$0.30, decks $0.20–$0.45, and roofs $0.20–$0.60 (soft-wash). Most pros use the per-sq-ft rate to build a flat quote, not to bill you by the foot.

Almost every pressure-washing quote starts from a per-square-foot rate, even when the pro gives you a single flat price. Knowing the rate by surface tells you whether a quote is fair.

Per-square-foot by surface

Surface	Cost / sq ft	Method	Recommended PSI
Vinyl & painted siding	$0.15–$0.30	Soft wash	< 500 PSI
Stucco	$0.20–$0.40	Soft wash	< 500 PSI
Brick & masonry	$0.15–$0.35	Low pressure	500–1,000
Concrete driveway	$0.10–$0.25	Pressure + surface cleaner	3,000
Wood deck & fence	$0.20–$0.45	Low pressure, wood-safe	500–1,200
Roof (tile / shingle / metal)	$0.20–$0.60	Soft wash only	< 500 PSI

Why the range is wide

Two things move the number within each band: how dirty the surface is (heavy algae or oil needs more solution and dwell time) and access (a second story, tight landscaping, or a steep roof adds labor). Soft-wash surfaces (siding, roofs) cost a bit more per foot than a plain concrete blast because the cleaning solution does the work.

From rate to flat quote

A good pro measures the area, applies the per-foot rate, then quotes a flat price for the job. That protects you from an open meter. If someone quotes strictly by the hour with no cap, ask for a not-to-exceed number. Our full cost hub and estimator turns these rates into a range for your specific home.
