Power washing a house exterior typically costs $250-$650 for a standard one- or two-story home, with an average near $425. The final price depends on siding type, home size, soil level, access, cleaning method, and whether extras such as gutters or a driveway are included.
Low quotes often cover an uncomplicated, smaller home; larger properties, delicate siding, heavy buildup, and regional labor rates can push the bill higher.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| House exterior wash | $150 | $425 | $900 | Typical residential siding job |
| Price per exterior square foot | $0.15 | $0.35 | $0.75 | Measured or estimated wash area |
| Small, one-story home | $150 | $275 | $450 | About 1,000-1,500 sq. ft. of living area |
| Large or complex home | $500 | $700 | $1,200 | More area, height, buildup, or access work |
Exterior House-Washing Prices for Common Home Sizes
For a typical U.S. home, the price is usually $250-$650. A smaller, single-story property with vinyl siding and ordinary dust may cost $150-$350. A two-story home with more wall area and moderate grime commonly lands around $350-$750. Large homes, complex elevations, or substantial algae and mildew can reach $800-$1,200 or more.
Contractors may charge by exterior square foot, by home size, or by job. A rough planning rate is $0.15-$0.75 per square foot of washable exterior surface, with $0.25-$0.50 common for straightforward work. This is not the same as the home’s interior floor area: wall height, attached garages, dormers, and architectural features affect the amount to be cleaned.
For a standard 1,800- to 2,400-square-foot home, a practical starting budget is $300-$600. That range assumes accessible siding, standard cleaning, and no major repairs or unusual contamination. Assumptions: U.S. contractor, normal access, standard cleaner, and routine residential soil.
Minimum service charges can make small jobs look expensive per square foot. A contractor may set a $150-$250 minimum to cover travel, setup, and equipment, even if the home’s washable area is limited. Ask whether the estimate includes all exterior walls, porch ceilings, trim, and attached garage walls.
What Siding, Labor, and Cleaning Supplies Include
A house-washing quote generally combines labor, equipment, cleaning solution, water handling, travel, and business overhead. The table shows typical portions of a residential bill; the actual share varies with the contractor’s pricing method and the site’s difficulty.
| Quote component | Typical charge | What changes it | Common scope |
|---|---|---|---|
| Labor | $100-$350 total | Wall area, height, prep, and crew size | Setup, application, rinsing, and cleanup |
| Equipment and vehicle | $25-$100 total | Travel distance and specialty equipment | Washer, hoses, ladders, and transport |
| Cleaning solution | $10-$60 total | Surface, buildup, and treatment strength | Detergent or treatment for organic growth |
| Overhead and insurance | $40-$175 total | Company operating costs and job risk | Scheduling, insurance, and administration |
| Disposal or water control | $0-$100 total | Runoff rules and site conditions | Containment or additional cleanup if needed |
Labor often accounts for the largest direct expense. Residential exterior cleaning labor can work out to roughly $50-$100 per worker-hour, though most customers receive a flat project quote rather than an hourly bill. A two-worker crew on a three-hour job could represent $300-$600 in labor before equipment, materials, overhead, and any minimum charge.
Ask for a written scope that distinguishes the house wash from optional add-ons. One quote may include exterior trim and a light porch rinse, while another may price them separately. Confirm whether the contractor will protect outdoor outlets, avoid forcing water behind siding, and use a cleaning method suitable for the home’s materials.
Which Siding and Height Details Raise the Quote
Surface material affects both labor and technique. Vinyl and many painted surfaces can often be cleaned with low-pressure application and rinsing, while wood, older masonry, and delicate finishes may need more careful treatment. A change in method can add time or require a specialist; it does not automatically mean the surface should be blasted at high pressure.
Height is another major price driver. A one-story home with easy ground access usually costs less than a two-story property with steep grades or hard-to-reach gables. Homes over about 25 feet tall, or with three stories, may require additional equipment, safety measures, or a specialized crew. Access charges can add $75-$250 or more when setup is unusually difficult.
Size thresholds help explain differences between estimates. A home with up to about 1,500 square feet of living area may have a simple exterior footprint, while a 2,500- to 3,500-square-foot home often has significantly more wall area, attached structures, and trim. These are rough indicators, not a direct conversion to washable surface area.
Heavy algae, mildew, oxidation, or long-neglected dirt can require pretreatment or a second application. A mild-to-moderate buildup may fit a standard service, but severe growth can add $50-$250 depending on the affected area and treatment. Oxidized siding may need specialized handling; aggressive pressure can leave streaking or damage rather than restore the finish.
Check that the quote names the siding and cleaning approach, not just a machine pressure rating. For a delicate surface, ask how the contractor will control spray, protect landscaping, and test a small area. Any extra charge should correspond to a specific access issue, treatment, or additional scope.
Crew Time for 1,500- to 3,000-Square-Foot Homes
A straightforward wash on a small, one-story home may take one worker about 2-4 hours on site, including setup and cleanup. A two-person crew may finish the same scope in roughly 1.5-3 hours. A 2,000- to 3,000-square-foot two-story home often takes a two-person crew 3-5 hours, depending on access and buildup.
These time estimates assume the contractor can reach water and work around the home without extensive moving or protection. Dense landscaping, narrow side yards, detached structures, multiple rooflines, and stubborn growth can add one or more hours. Very large or complex properties may need a longer visit or a second appointment.
Hourly rates are useful for comparing labor but do not predict the full invoice by themselves. A flat quote may include travel and equipment, while a time-and-materials estimate may add charges for extra treatment or unexpected obstacles. Ask whether the quoted price changes if a crew finishes early or encounters more grime than expected.
Most standard house washes are completed in one visit, but the time on site is not the only pricing factor. Setup, drive time, equipment maintenance, insurance, and minimum charges are built into many flat rates. A low hourly figure can therefore produce a higher total if fees and extras are separate.
When Gutters, Driveways, and Decks Add Charges
Extras are often priced separately because they require different methods, more time, or additional equipment. Gutter brightening, which targets exterior staining, commonly adds $1-$3 per linear foot. Interior gutter debris removal is a different service and may cost $1-$2.50 per linear foot, with higher charges for height, guards, or heavy blockage.
A driveway wash commonly adds $100-$300 for an average two-car driveway, or about $0.15-$0.35 per square foot. Larger or heavily stained concrete can cost more. Deck cleaning may run $150-$500 for a typical deck, depending on size, material, stairs, railings, and whether it needs a separate stain or sealant service.
Other potential add-ons include a detached garage, patio, fence, porch, or screen enclosure. A small patio may add $50-$150, while a fence can be priced by area or linear footage. Ask whether the quote includes a rinse of windows and screens; cleaning window glass or removing hard-water deposits is generally a separate service.
Preparation can also affect the bill. Moving furniture, covering delicate plants, securing loose items, and closing windows are usually homeowner tasks, but some contractors include limited prep. Difficult water access, a long hose run, or a property with restricted drainage could add $25-$150 when extra setup or runoff control is required.
Have each extra listed as an optional line item with its own unit and price. This makes it easier to compare a house-only quote against a bundled estimate without paying for surfaces that do not need cleaning.
How U.S. Region and Water Access Shift Rates
Local labor costs and contractor availability can move an estimate well above or below broad national ranges. In lower-cost rural markets, a straightforward wash may come in about 10%-20% below a national midpoint, although long travel distances can offset the savings. Major metro areas and high-cost coastal markets may run 15%-35% higher for comparable work.
Climate and local conditions influence demand and the amount of treatment needed. Humid areas with persistent algae or mildew may call for more frequent cleaning or additional pretreatment. Dry regions may see less organic growth but more dust. These conditions affect the quote through labor and cleaning steps rather than a uniform regional surcharge.
Water access is a practical pricing detail. A standard outdoor spigot close to the work area usually keeps setup simple. A property without accessible water may require a water tank or other arrangements, potentially adding $50-$200 or more depending on the distance and volume required. Confirm in advance whether the contractor supplies water or expects access to the home’s supply.
Compare local estimates for the same home, wash method, and included surfaces. A regional percentage is only a budgeting guide: the home’s condition, minimum service charge, travel distance, and site access can matter more than the state or city alone.
Soft Washing Versus Pressure Washing on Siding
Many exterior house washes use a low-pressure cleaning approach, often called soft washing, rather than directing high pressure at siding. A standard soft wash may cost about $250-$650 for an average home. A more labor-intensive treatment for heavy organic growth or a delicate surface can reach $500-$900, depending on size and access.
Higher-pressure washing may be suitable for some hard surfaces, such as concrete, when used correctly, but it is not automatically the cheaper choice for siding. Excessive pressure can force water behind cladding, strip paint, damage wood, or harm seals. The right method depends on the surface and the kind of contamination, not simply on the lowest advertised price.
DIY rental can appear less expensive, with equipment rentals often around $50-$150 per day, plus solution and supplies. However, a rental machine may not include the correct low-pressure setup, and mistakes can cause costly damage. DIY is less suitable for multi-story homes, fragile siding, and jobs that require careful chemical application or ladder work.
Repairing a small isolated stain or rinsing a limited area may cost less than a full house wash. If the problem is localized, ask whether a targeted cleaning is available and whether it will blend with the surrounding surface. A full wash may be more practical when buildup is widespread, but the quote should explain the scope.
Choose the cleaning method around siding condition and soil, not the machine’s maximum pressure. A low-pressure application can be effective for many house-washing jobs and may reduce the risk of damage, though some surfaces and stains require a different process.
Where Homeowners Can Trim Exterior Washing Costs
Start by defining exactly what needs cleaning. A house-only wash costs less than a package that includes gutters, a deck, a fence, and hardscaping. Separate essentials from optional surfaces and request individual prices, so the estimate can be reduced without removing a necessary treatment from stained or delicate siding.
Compare at least three local written quotes with matching specifications. Each should state the home size or measured area, siding type, cleaning method, included surfaces, treatment for heavy growth, and any access or travel fees. A quote far below the others may exclude important areas or rely on a different method, so compare scope rather than totals alone.
Basic preparation can reduce paid labor. Clear toys and small furniture from the work area, close windows, secure pets, and identify outlets or water-sensitive items. Do not remove electrical equipment or climb ladders to prepare high surfaces. Confirm which tasks the contractor expects the homeowner to handle before the appointment.
Flexible scheduling may help when local contractors are less busy, but weather and seasonal demand vary by region. Ask whether a non-rush appointment or bundling the house with another nearby surface reduces the total. Bundling is worthwhile only when the added service is actually needed and the combined quote is lower than separate work.
The safest savings usually come from limiting scope, preparing accessible areas, and comparing like-for-like quotes. Avoid choosing a low bid that proposes excessive pressure, skips surface protection, or leaves the cleaning method unclear; damage to siding, paint, or seals can cost more than the original wash.
