Pressure Washing Cost Calculator
Estimate the cost of pressure washing services based on surface type, square footage, and additional factors.
Surface Type
Driveway (Concrete/Asphalt) Deck or Patio (Wood) Deck or Patio (Composite) Sidewalk / Walkway House Siding (Vinyl) House Siding (Brick/Stucco) Fence (Wood) Roof Parking Lot
Surface Area (sq ft)
Number of Stories (for siding/roof)
1 Story 2 Stories 3+ Stories
Surface Condition
Light Dirt / Regular Maintenance Moderate Staining / Mildew Heavy Staining / Long Neglect
Location / Market
Rural Suburban Urban / High Cost of Living
Add Sealing / Treatment After Wash?
No Yes — Concrete/Asphalt Sealing (+$0.30/sq ft) Yes — Wood Deck Sealing (+$0.50/sq ft) Yes — Brick/Stone Sealing (+$0.40/sq ft)
Travel / Mobilization Fee ($)

#### Formula
Base Washing Cost = max( Area × Base Rate × Stories Multiplier × Condition Multiplier × Location Multiplier, $75 )
Sealing Cost = Area × Sealing Rate per sq ft
Total Cost = Base Washing Cost + Sealing Cost + Travel Fee
Estimated Range = Total Cost × 0.85 to Total Cost × 1.15 (±15%)
Base Rates by Surface: Driveway $0.08, Wood Deck $0.15, Composite Deck $0.12, Sidewalk $0.10, Vinyl Siding $0.20, Brick/Stucco $0.25, Wood Fence $0.18, Roof $0.22, Parking Lot $0.07 (all per sq ft)
Stories Multiplier: 1 story = 1.0×, 2 stories = 1.25×, 3+ stories = 1.5×
Condition Multiplier: Light = 1.0×, Moderate = 1.2×, Heavy = 1.5×
Location Multiplier: Rural = 0.85×, Suburban = 1.0×, Urban = 1.3×
