What Drives Power Washing Costs?
Power washing costs from $250 to $1,200 for a whole-home visit are primarily determined by the square footage and number of surfaces, the type of surface, and the severity of buildup. Here is what moves the price.
Surface Type and Area
Different surfaces have different cleaning times and requirements. Concrete driveways are fast to clean per square foot. Wood decks require more careful pressure calibration to avoid damage and may need pre-treatment. Brick and masonry require specific pressures to avoid mortar damage. House siding type matters: vinyl siding tolerates higher pressure than wood siding, stucco, or EIFS (synthetic stucco), which require soft-wash low-pressure methods. Surface type affects both method and time, and therefore price.
Home Size and Square Footage
More square footage means more time. A 1,000-square-foot driveway costs more to clean than a 400-square-foot driveway. A 3,500-square-foot home exterior costs more than a 1,500-square-foot home. Companies that price by square footage make this relationship transparent those pricing by project scope factor it in when assessing the job.
Height and Access Difficulty
Single-story surfaces are the most economical. Two-story siding, eaves, and second-floor exterior surfaces require extension wands or ladders, adding safety setup time and labor cost. A two-story home exterior typically costs 25 to 50 percent more than a comparable single-story exterior due to height requirements.
Buildup Severity
Light surface dirt and dust wash off quickly. Heavy biological growth (moss, algae, lichen on driveways, walkways, or siding) and deep oil stains require dwell time with cleaning solution, multiple passes, or specialty treatments. Any surface that has not been cleaned in more than 3 to 5 years typically requires more time and effort and may be priced higher than a maintained surface of equal area.
Power Washing Cost at a Glance
Standard single-family home: $250 to $650 for exterior walls, driveway, and sidewalk on one visit.
Large home or multiple surfaces: $550 to $1,300 for siding, driveway, deck, and fence on a larger property.
Single surfaces booked alone: driveway and sidewalk $75 to $350; deck, patio, or fence $100 to $350. Booked on their own they fall below the whole-visit range.
Method matters: pressure washing siding runs $212 to $447; soft washing the same siding runs $300 to $800.
Heavy grime or mold: Added cost for stubborn buildup needing more time and stronger solutions.
Overall range: $250 to $1,200 for a whole-home visit, averaging $450.
Planning Your Project Budget
The cost ranges in this article are based on industry data and are intended as planning benchmarks, not fixed prices. The actual cost for your project depends on your specific home, your local labor market, the current price of materials, and the scope the contractor confirms after a site inspection.
Always get at least two written quotes on equivalent defined scope before committing to any home services project. Wide price variation between quotes usually reflects differences in material quality, scope completeness (what is included and what is not), or contractor overhead and experience level rather than simple price competition.
Use the cost data in this article to ask better questions during the quoting process: What material is included? What does that per-square-foot or per-linear-foot rate include and exclude? Are permits, cleanup, and disposal included? What is the warranty on labor? These questions turn a quote into a comparable basis for decision-making.

Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
