Every spring, thousands of homeowners ask the same question: how much to pressure wash a deck? The answer drives budgeting, scheduling, and whether the job becomes a weekend DIY project or a professional service call. At CountBricks, we generate real-time estimates through voice conversation, instantly pulling verified labor rates, material prices, and task durations so you can quote with confidence. Below, our residential construction experts break down national averages, regional adjustments, and cost-saving strategies.
• National average per square foot: $0.40 – $0.95
• Typical small deck (150 sq ft): $60 – $140
• Typical mid-size deck (300 sq ft): $120 – $285
• Large entertainment deck (500 sq ft+): $200 – $475
These figures come directly from the live cost database that powers CountBricks.com/services and update daily to reflect lumber supply fluctuations and local labor markets.
• Deck size: Pressure washing is billed by square footage; larger surfaces amplify both labor hours and water usage.
• Material type: Cedar and composite tolerate different PSI levels. Softer woods demand slower passes, increasing time on site.
• Existing finish: Stripping a failing stain adds detergent costs and another pass with a low-angle tip.
• Height & accessibility: Second-story walkouts require ladder setups and harnesses, raising labor premiums 10-15 %.
• Regional labor rate: Metro areas like Denver average $52/hr for a two-person wash crew; smaller towns hover near $38/hr.
• Add-ons: Mildew treatment, brighteners, and post-wash sealing can double total spend but extend deck life by years.
1. Labor (60-70 %): Setup, surface prep, nozzle swaps, controlled passes, and cleanup.
2. Materials (20-25 %): Water, detergents, fuel or electricity for the washer, PPE consumables.
3. Overhead & margin (10-15 %): Insurance, equipment depreciation, and profit.
CountBricks transparently displays each line item, allowing contractors to adjust crew size or detergent quality in seconds during a live phone conversation with the client.
• Equipment rental: $45-$65/day for a 3,000 PSI unit
• Chemicals & PPE: $20-$40
• Learning curve & risk: One misjudged nozzle can scar softwood, leading to $8-$12/sq ft board replacement.
