Homeowners search “how much does power washing house cost” thousands of times each month, but the answer can feel like a moving target. At CountBricks, we combine field-tested construction data with real-time AI estimating to deliver clarity. Whether you’re a DIY-minded homeowner, a remodeling contractor, or a property manager, understanding the true cost drivers behind residential power washing helps you set realistic budgets and create winning proposals.
Removing mildew, loose paint, and embedded dust extends the life of exterior finishes and boosts curb appeal—often for a fraction of repainting costs. CountBricks clients routinely see home values climb after a professional wash, making this one of the highest-ROI maintenance tasks we track in our platform.
Aggregated U.S. data puts the typical cost between $0.35 and $0.80 per square foot. However, our AI pulls localized supplier pricing and labor rates every morning. In Des Moines, for example, the average single-story 2,000 sq ft home totals $490—including setup, 3-hour labor, detergents, and a moderate mildew treatment. Coastal regions with stricter runoff regulations often land 10-15% higher.
• Square footage of siding, trim, and attached structures (decks, porches, garages)
• Material type—vinyl, fiber-cement, brick, or painted wood absorb different labor times and PSI rules
• Height and accessibility—two-story homes require taller ladders or lifts, increasing setup minutes and insurance premiums
• Severity of buildup—light dust needs no detergent dwell time; heavy algae doubles chemical usage
• Local environmental fees—runoff containment, gray-water disposal, or HOA compliance add line-items in certain zip codes

Our software auto-populates these tasks in every estimate, complete with current labor rates pulled from CountBricks.com/services.
Labor accounts for roughly 70% of the invoice. A two-technician crew in the Midwest averages $55-$65 per hour fully burdened. Material costs stay modest—typically $40-$65 for detergents, soft-wash additives, and PPE. Equipment amortization (pump, hoses, surface cleaner) adds another $25-$40 per project in the CountBricks database.
Traditional contractors still scribble square foot guesses onsite. CountBricks skips the tape measure:
• Upload a blueprint or exterior elevation photo to CountBricks.com/takeoffs
• Speak dimensions aloud—our voice assistant converts them to line-items in real time
• Adjust detergent concentration or ladder height with simple voice commands
• Receive a full PDF proposal, work order, and branded invoice in under five minutes
• Bundle services—add driveway or deck cleaning to spread trip fees across more square footage
• Schedule in shoulder seasons—spring and fall mean less demand and faster drying times
• Ensure exterior water access—technicians waste fewer minutes running hoses from basements
• Remove fragile décor—reduces liability mark-ups included by cautious contractors
A big-box rental washer costs $90 per day plus $25 in chemicals. Add four hours of your own time, potential ladder rental, and the risk of siding damage from incorrect PSI. CountBricks estimates the out-of-pocket DIY total at $160-$220. A seasoned crew may quote $400-$600, but the service includes liability insurance, water runoff management, and a workmanship guarantee. For many homeowners, the delta buys peace of mind and protects exterior finishes.

• Moderate mildew, easy hose access

Last spring, the Rodriguez family planned to list their 2,400 sq ft cedar-lap home. Realtor photos exposed dark streaks that dulled the siding’s warm tone. Traditional contractors quoted a flat $900, citing “cedar premiums.” The family’s GC opened CountBricks, uploaded the exterior elevation, and spoke measurements:
1. Front & rear façade 55 ft × 22 ft
2. Gable peaks 350 sq ft combined
3. Wrap-around porch 180 sq ft railing
Within four minutes the AI returned labor at current $62.50/hr, cedar-safe detergent at $0.18/sq ft, and a local gray-water fee of $27. The final bid: $739.46—an 18% savings. The crew booked through CountBricks.com/portfolio completed the job in one afternoon. The home sold above asking two weeks later.
