For a concrete patio, professional power washing costs between $130 and $220. Concrete costs less to clean than brick or pavers because it can withstand higher pressure levels without damage. Your specific cost will depend on your patio's dimensions, condition, and location. Many professionals base their pricing on square footage, with rates for concrete surfaces falling within the $0.10 to $0.50 per square foot range.
Although the terms are often interchangeable, power and pressure washing refer to different cleaning methods. Power washing utilizes heated water, while pressure washing uses water at normal temperature. The heat component in power washing makes it more effective for breaking down stubborn substances like grease, mold, and mildew. Power washing services cost more than standard pressure washing due to the specialized equipment required. For standard residential patios, standard pressure washing is usually sufficient.
A professional completes power washing for an average-sized patio in one to two hours. Factors that may extend this timeframe include complex layouts, extensive staining, or particularly large surfaces. DIY power washing takes longer due to equipment setup time, less powerful equipment, and the learning curve associated with proper technique. Professional services often complete jobs more efficiently due to experience and commercial-grade equipment.
While not mandatory, sealing provides valuable protection for your freshly cleaned patio. Professional sealing services cost between $180 and $370 and offer benefits like enhanced color appearance, protection against stains, prevention of weed growth between pavers, and extended cleanliness. For optimal results, the patio surface should be completely dry before applying sealant, which requires at least 24 hours after power washing.
Professional power washing services include several value components beyond just equipment access. Professionals bring specialized knowledge about appropriate pressure levels for different materials, preventing potential damage that DIY efforts might cause. Their commercial-grade equipment delivers more effective cleaning in less time. While DIY approaches save on service fees, they require investments in equipment rental or purchase, cleaning solutions, and significantly more of your personal time. Many homeowners find that professional services provide better results and greater convenience.
