The average cost to pressure wash a house is about $350, with many U.S. jobs ranging from $200 to $600. Home size, siding condition, number of stories, cleaning method, and local labor rates drive the final quote; delicate siding may need lower-pressure soft washing instead of direct pressure.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house exterior wash | $150 | $350 | $800 | Typical house, siding only; extensive buildup costs more |
| One-story house | $150 | $275 | $450 | Easy access and standard vinyl siding |
| Two-story house | $300 | $475 | $800 | Height, layout, and access affect labor |
| Exterior surface pricing | $0.10/sq ft | $0.25/sq ft | $0.50/sq ft | Rates may use washable siding area, not indoor floor area |
What a Typical House Wash Costs by Size
For a roughly 1,500-square-foot, one-story home with accessible vinyl siding, expect about $200-$400. A 2,000- to 2,500-square-foot two-story house commonly falls near $350-$650, while large homes, complex exteriors, or heavy algae can reach $800 or more. These are prices for washing exterior siding, not roof cleaning or full property washing.
A practical national budget is $250-$600 for a standard house wash. Contractors may calculate by exterior wall area, home size, or a minimum service charge. A per-square-foot rate can be misleading if the quote does not specify whether it applies to siding, total wall surface, or another measured area.
Assumptions: U.S. mid-market labor rates, standard siding, normal access, and no major repairs or unusual contamination.
How Labor, Cleaning Solution, and Setup Shape the Quote
Most residential quotes combine labor, equipment, cleaning chemicals, and business costs. A basic wash generally includes setup, rinsing, detergent application where needed, and cleanup. The breakdown below illustrates how a $350 quote might be allocated; contractor pricing varies and may bundle these charges rather than itemize them.
| Cost component | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Labor | $100 | $190 | $350 | Time on site, crew size, height |
| Equipment and setup | $20 | $45 | $90 | Hose length, access, machine setup |
| Detergent and treatment | $10 | $25 | $60 | Algae, mildew, or heavier soil |
| Overhead and travel | $20 | $50 | $120 | Distance, insurance, local operating costs |
| Typical total | $150 | $350 | $800 | Scope and site conditions determine final quote |
Labor often represents the largest share. For a crew billing an estimated $50-$100 per worker-hour, a two-person team working 2-3 hours can account for $200-$600 before bundled discounts or other charges.
Ask whether the price includes detergent, rinsing, setup, and travel. An unusually low base quote may exclude treatments or charge separately for them.
Why Siding Type, Height, and Grime Change the Price
Exterior material and cleaning method affect both time and risk. Vinyl and many painted surfaces are commonly soft washed with controlled pressure and detergent. Brick, stucco, wood, and older paint may require different pressure, products, or extra care; some porous or fragile surfaces are not suited to aggressive washing.
Height is a measurable price driver: a one-story home is generally less labor-intensive than a two-story home, and steep slopes or difficult ladder access can add roughly 10%-30%. Heavy algae, mildew, or embedded dirt may add $50-$200 when the contractor needs stronger treatment or a second application. Long hose runs, fenced yards, and limited water access can also extend setup.
More pressure is not automatically a better clean. On delicate siding, inappropriate pressure can force water behind panels or damage finishes, so the cleaning method should match the surface.
What Regional House-Washing Quotes Look Like
Prices vary with local wages, contractor availability, travel distances, and climate-related demand. In lower-cost rural markets, a standard wash may run about 10%-20% below the national midpoint. Dense, high-wage metro areas often come in 15%-35% above it, especially where parking or access is difficult.
Warm, humid areas with frequent algae growth may see repeat-cleaning demand and more treatment work; cold-weather markets may have a shorter operating season. These are broad comparison ranges, not fixed regional tariffs. For a $350 baseline, a 20% increase would put the comparable quote near $420, while a 15% decrease would put it around $300.
Compare local quotes for the same surfaces and cleaning method. A roof, gutters, deck, or driveway included in one estimate makes it unsuitable for direct comparison with a siding-only price.
Three House-Wash Quotes for Common Home Sizes
The examples below show how scope can produce different totals. Labor hours refer to approximate on-site crew time, not total combined worker-hours. Local prices may be higher or lower, and separate surface cleaning is not included.
| House and scope | Approximate labor | Rate basis | Estimated total |
|---|---|---|---|
| 1,200-sq-ft one-story vinyl home, light soil | 1-2 hours | About $0.17-$0.25 per sq ft | $200-$300 |
| 2,000-sq-ft two-story home, moderate algae | 2-3 hours | About $0.20-$0.30 per sq ft | $400-$600 |
| 3,000-sq-ft home, difficult access and heavy buildup | 3-5 hours | About $0.25-$0.40 per sq ft | $750-$1,200 |
The largest example may exceed the usual range because it includes both a larger home and more involved cleaning conditions. Confirm which walls are included, whether dormers and detached structures count, and how the contractor defines square footage.
When Prep, Add-Ons, or Minimum Fees Raise the Bill
Many companies set a minimum visit charge of about $150-$250, even for a small house, because travel and setup take time. Removing outdoor furniture, protecting plants, and securing windows are often homeowner prep tasks. Contractors may charge extra if items must be moved or delicate landscaping needs additional protection.
Optional work is commonly priced separately: driveway washing may add $100-$300, a deck $100-$250, and gutter exterior brightening $50-$150. Roof washing is a separate, higher-risk service and should not be treated as an automatic add-on to a house-wash quote. Ask whether the contractor charges a separate trip fee for small jobs.
Get the included surfaces and add-on prices in writing. A low starting fee can become a larger bill when each extra area is priced individually.
How to Lower the House-Washing Price Without Cutting Corners
Compare at least three written estimates that describe the same siding area, cleaning method, and included treatment. Ask for a total price and any minimum, travel, or access charges. If nearby homes need washing, coordinating appointments may reduce travel or setup costs, though the contractor decides whether to offer a discount.
Remove movable items and provide clear access to exterior walls before the crew arrives. Schedule routine cleaning before thick buildup requires repeat treatment, and avoid paying for roof, driveway, or deck work that is not needed. Do not request a lower price by asking for excessive pressure on a surface that calls for soft washing.
The most reliable savings come from matching the scope to the house, not skipping safe cleaning steps. A quote should identify the surfaces, method, treatment, cleanup, and conditions that could trigger extra charges.
