How Much Does Power Washing Cost?
Power washing removes dirt, algae, mold, and stains from your home's exterior surfaces. Most homeowners spend $150–$500 per project, with costs determined by surface type, area, and soil severity. Use our calculator to get a personalized estimate.

What affects the cost
These are the main variables that shift the final price up or down.
Surface type and material
High impactHouse exterior ($0.15–$0.40/sq ft), driveway ($0.10–$0.25/sq ft), and deck/patio ($0.15–$0.35/sq ft) have different pricing based on material durability and cleaning difficulty.
Soil and stain severity
High impactLight cleaning costs less than heavy mold, algae, or rust stain removal, which may require pre-treatment chemicals or extended pressure application.
Total square footage
High impactLarger areas benefit from economies of scale; contractors often charge slightly less per square foot for projects exceeding 3,000 sq ft.
Equipment and pressure settings
Medium impactDelicate surfaces (wood decks, vinyl siding) require lower PSI and specialty nozzles; concrete and asphalt tolerate higher pressure, reducing time and cost.
Travel distance and accessibility
Medium impactSteep rooflines, multi-story homes, or hard-to-reach areas may incur additional labor or equipment fees.
Regional labor rates
Medium impactUrban and high-cost-of-living areas typically charge 20–40% more than rural regions for the same service.
Chemical treatments
Low impactOptional algaecide, mold preventative, or sealing treatments add $0.05–$0.15/sq ft but extend surface life.
How power washing cost calculator pricing works
Power washing uses high-pressure water jets (typically 1,500–4,000 PSI) to clean driveways, decks, siding, and patios. Contractors adjust pressure and nozzle type based on material—delicate wood requires lower PSI than concrete. Heavy stains may require pre-treatment with biodegradable detergents. Most residential jobs take 2–6 hours depending on area and condition. Results are immediate and can dramatically improve curb appeal.
Power Washing Cost Breakdown
Power washing costs typically range from $150 to $500 for a standard residential project, with the national average around $300. Your final price depends on three primary factors: the type of surface, the total area being cleaned, and how heavily soiled the surfaces are.
House Exterior Cleaning
Cleaning vinyl siding, brick, or stucco costs $0.15 to $0.40 per square foot. A typical 2,000 sq ft house exterior runs $300–$800. Light cleaning (annual maintenance) falls on the lower end; heavy cleaning with mold or mildew removal costs more. Contractors may charge extra for second-story work requiring ladders or lifts, and delicate materials like wood shingles need lower pressure to avoid damage.
Driveway and Concrete Cleaning
Driveways and concrete surfaces cost $0.10 to $0.25 per square foot. A standard 500 sq ft driveway runs $50–$125 standalone, but is often bundled with house cleaning. Asphalt requires gentler pressure than concrete to avoid damage. Oil stains, tire marks, and algae growth increase costs. Sealing after cleaning (optional) adds $0.10–$0.20/sq ft but extends surface life by 2–3 years.
Deck and Patio Cleaning
Wood decks and composite patios cost $0.15 to $0.35 per square foot. A 400 sq ft deck runs $60–$140. Wood requires careful pressure control (under 1,500 PSI) to avoid splintering and grain damage. Composite materials are more forgiving. Mold, algae, and mildew removal on shaded decks costs more due to pre-treatment chemicals. Sealing or staining after cleaning (separate service) protects the wood.
Factors That Increase Power Washing Costs
Soil and Stain Severity: Light annual cleaning costs 30–40% less than heavy mold, rust, or algae removal. Stubborn stains may require specialized treatments or multiple passes.
Equipment and Pressure Settings: Contractors using commercial-grade equipment or hot-water pressure washers charge more but deliver superior results. Hot water is especially effective for grease and oil removal.
Accessibility and Height: Second-story siding, steep rooflines, or hard-to-reach areas require scaffolding, lifts, or extra labor. Expect 20–50% premiums for complex jobs.
Regional Labor Rates: Urban markets and high-cost-of-living regions charge 20–40% more than rural areas. California, New York, and Texas typically run higher than the Midwest.
Chemical Treatments: Pre-treatment detergents, algaecide, or post-cleaning sealers add $0.05–$0.15 per square foot but prevent regrowth for 6–12 months.
Money-Saving Tips
- Bundle Services: Cleaning house exterior + driveway + deck together often costs 10–15% less than booking separately.
- Schedule Off-Season: Winter and early spring (before spring cleaning season) offer 15–25% discounts.
- Skip Optional Treatments: Algaecide and sealers are nice but not essential; skip them on your first cleaning to save 10–20%.
- Get Multiple Quotes: Prices vary widely; obtain 3–4 estimates to ensure competitive pricing.
- Annual Maintenance: Regular annual cleaning costs 30% less than deep cleaning every 2–3 years.
DIY vs. Professional Power Washing
Renting a pressure washer costs $50–$100 per day, plus detergent and your labor. For small projects (under 500 sq ft), DIY may save money. However, professional contractors bring commercial equipment, insurance, and expertise in pressure settings for different materials. Mistakes—like high-pressure damage to wood or vinyl—can cost hundreds to repair. Most homeowners find professional cleaning worth the investment for safety and results.
When to hire a pro
Hire a professional power washing contractor if your home has heavy mold, algae, or stubborn stains; if you have second-story areas or steep rooflines; or if you lack a pressure washer and the expertise to use it safely. Annual or bi-annual professional cleaning maintains curb appeal and prevents long-term damage. Schedule in spring or fall for best results and contractor availability.
Frequently asked questions
Most homes benefit from annual or bi-annual power washing. Light climates with minimal algae and mold may go 2 years; humid, shaded areas should be cleaned yearly to prevent mold buildup and wood rot.
Yes, if pressure is too high or nozzle is incorrect. Professional contractors adjust PSI based on material—vinyl siding needs 1,200–1,500 PSI, wood decks under 1,500 PSI, and concrete 3,000–4,000 PSI. DIY mistakes can cause splintering, cracking, or water infiltration.
Power washing uses high pressure (1,500–4,000 PSI) for tough stains on concrete and asphalt. Soft washing uses low pressure (under 500 PSI) with biodegradable detergents for delicate surfaces like wood, vinyl, and roofs. Soft washing costs slightly more but prevents damage.
Sealing is optional but recommended. It protects against UV damage, water infiltration, and stains, extending the surface life by 2–3 years. Sealing costs $0.10–$0.20/sq ft and should be done 48 hours after cleaning.
Most residential projects take 2–6 hours depending on area and soil level. A 2,000 sq ft house exterior typically takes 3–4 hours. Heavily soiled surfaces or multi-surface jobs (house + driveway + deck) may take 6–8 hours.
Yes. Many contractors now use biodegradable detergents and recycle wastewater. Hot-water pressure washers are more efficient than cold-water units. Ask your contractor about their environmental practices—many charge the same or slightly more for green options.
