How to Hire a Pressure Washing Contractor

Updated March 2026

Pressure washing removes dirt, mold, mildew, algae, and stains from driveways, sidewalks, decks, siding, and fences. Regular cleaning extends the life of exterior surfaces and is often required before painting or staining. Soft washing uses lower pressure with cleaning solutions for delicate surfaces like vinyl siding and roofing, while high-pressure washing tackles concrete and brick. A professional operator understands which surfaces require which PSI settings to avoid damage — too much pressure can gouge wood, etch concrete, or force water behind siding.

Typical cost

$150 – $600per project

Driveway: $100–$300. House exterior: $200–$600. Deck or patio: $100–$250. Prices vary by surface area and condition.

Hiring checklist

1Ask whether they use pressure washing or soft washing for your specific surface.
2Confirm they carry liability insurance — high-pressure water can cause property damage.
3Ask about their approach to protecting landscaping and windows during the job.
4Get a flat-rate quote rather than hourly to avoid cost surprises.
