How Much Does Pressure Washing Cost?

How pressure washing cost calculator pricing works

Pressure washing uses high-velocity water jets (typically 1,500–4,000 PSI) to remove dirt, mold, algae, and stains from exterior surfaces. Contractors assess the surface material, soil level, and accessibility, then quote a price based on square footage and labor time. Some jobs require pre-treatment chemicals, multiple passes, or specialized equipment, which increases the final cost. Most projects are completed in 2–6 hours.

Pressure Washing Cost by Surface Type

The type of surface you're cleaning is one of the biggest cost drivers. Different materials require different pressure levels, techniques, and cleaning solutions to avoid damage while achieving optimal results.

Concrete Driveways & Patios

Concrete is the most common pressure washing project. Driveways typically cost $100–$250 per project (500–1,500 sq ft), or about $0.08–$0.15 per square foot for moderate cleaning. Heavily stained concrete with oil, rust, or algae runs $0.15–$0.22 per sq ft. Contractors can use higher PSI (2,500–4,000) on concrete without risk of damage, making it relatively fast and affordable.

House Exterior & Siding

Pressure washing a house exterior (vinyl, brick, or fiber cement siding) costs $150–$400 per project for a typical 2,000–3,000 sq ft home, or $0.07–$0.18 per sq ft. Vinyl siding requires lower pressure (1,200–1,500 PSI) to prevent damage, which can increase labor time. Brick and stone are durable but may need chemical treatment for heavy mold or algae, adding $50–$100 to the bill.

Decks & Wooden Surfaces

Wood decks and fences cost $100–$250 per project (300–1,000 sq ft), or $0.10–$0.22 per sq ft. Wood is delicate and requires lower pressure (500–1,200 PSI) and careful technique to avoid splintering or gouging. Pre-treatment with mold or algae killer is often necessary, and some contractors charge extra for sealing recommendations afterward.

Roofs, Gutters & Downspouts

Roof cleaning (soft-wash method to prevent damage) costs $200–$400 per project. Gutter cleaning with pressure washing runs $75–$200. These jobs require safety equipment and careful pressure control, justifying higher labor rates.

Cost Breakdown by Dirt Level

Light Cleaning: $0.07–$0.10 per sq ft. Suitable for routine maintenance (annual or semi-annual cleaning). Minimal buildup, no mold or algae.

Moderate Cleaning: $0.11–$0.15 per sq ft. Standard job with visible dirt, minor stains, or light algae. Most residential projects fall here.

Heavy Cleaning: $0.16–$0.25 per sq ft. Significant mold, algae, oil stains, or years of buildup. Requires pre-treatment chemicals, longer dwell time, and multiple passes.

Additional Costs & Fees

Travel & Setup: $25–$75 if the contractor must travel more than 15–20 miles or set up equipment far from the water source.

Chemical Treatments: $50–$150 for eco-friendly or specialized cleaning solutions (mold killer, degreaser, rust remover).

Sealing or Protection: $0.50–$2.00 per sq ft to apply protective sealant after cleaning (recommended for wood and natural stone).

Accessibility Surcharge: $50–$200 if the job requires scaffolding, lifts, or safety equipment for high or hard-to-reach areas.

Debris Removal: $25–$75 if significant debris (leaves, loose paint, dirt piles) must be hauled away.

Regional Price Variations

Pressure washing costs vary by region due to labor rates and local demand:

• Northeast & West Coast: 20–40% above national average ($180–$700 for typical projects)
• Midwest & South: 10–20% below national average ($120–$400 for typical projects)
• Urban areas: 25–35% premium over suburban rates
• Seasonal demand: Spring and summer (peak cleaning season) may have 10–15% higher prices

How to Reduce Pressure Washing Costs

1. Bundle services: Combine driveway, deck, and house washing into one appointment for a 10–20% discount.
2. Schedule off-season: Fall and winter typically have lower rates and more contractor availability.
3. Do light prep: Remove loose debris, move vehicles, and clear the area to reduce setup time.
4. Negotiate for annual contracts: Many contractors offer 15–25% discounts for quarterly or semi-annual maintenance.
5. Get multiple quotes: Compare 3–5 local contractors; prices can vary by 30–50% for the same job.

When to hire a pro

Hire a professional pressure washing contractor when you notice visible dirt, algae, mold, or stains on exterior surfaces that regular cleaning won't remove. Most homeowners benefit from annual or semi-annual pressure washing to maintain curb appeal and prevent long-term damage. If you have delicate surfaces (wood, vinyl siding, or composite materials), professional expertise is essential to avoid costly damage. DIY pressure washers can cause injury or property damage if used incorrectly, making professional service a safer choice for most homeowners.
