Pressure washing is an effective way to clean various outdoor surfaces, removing dirt, grime, mold, mildew, and other unsightly build-ups. When hiring a professional, understanding how estimates are calculated can help you budget and choose the right service.
Key Factors Influencing Pressure Washing Costs:
- Surface Area (Square Footage): This is often the primary driver of cost. Larger areas naturally require more time, water, and cleaning solutions, leading to a higher overall price. Most contractors will have a base rate per square foot.
- Type of Surface: Different materials require different pressure levels and cleaning techniques.
- Concrete: Driveways, patios, and sidewalks are generally robust and can withstand higher pressure, often making them quicker to clean per square foot.
- Siding: Vinyl, aluminum, or wood siding requires a softer touch (often "soft washing") to prevent damage, which can sometimes take more time.
- Decks: Wood or composite decks need careful pressure to avoid splintering or etching. Cleaning and potentially brightening/sealing can add to the cost.
- Roofs: Roof cleaning (especially asphalt shingles) almost always uses a soft wash method to protect the shingles. This is a specialized service and often priced higher due to the risk and specific chemicals involved.
- Level of Dirt/Stain: The severity of the build-up directly impacts the effort and time required.
- Light: General dust, cobwebs, and minor grime.
- Moderate: Noticeable algae, moss, mildew, or general dirt that has accumulated over time.
- Heavy: Deeply embedded stains, significant organic growth, oil spots, or paint overspray that requires specialized treatment or multiple passes.
- Job Accessibility/Complexity: How easy or difficult it is for the technician to access and clean the area.
- Easy: Ground-level surfaces with clear access, no significant obstacles.
- Moderate: Second-story work, some landscaping obstacles, or areas requiring minor furniture moving.
- Difficult: Steep roofs, very tight spaces, extensive furniture moving, delicate landscaping, or areas requiring specialized equipment like lifts.
- Minimum Job Fee: Many pressure washing companies have a minimum charge to cover their operational costs (travel, setup, equipment wear, etc.), regardless of how small the job is. If your calculated cost falls below this minimum, you'll typically be charged the minimum fee.
- Additional Services: Services like rust removal, oil stain treatment, gutter cleaning, or sealing/sanding a deck are usually add-ons and will increase the total cost.
How to Use the Calculator:
Simply input the total square footage of the area you need cleaned. Then, select the type of surface, the estimated level of dirt, and the accessibility of the job. The calculator will provide an instant estimate based on typical industry rates and factors. Remember to also consider the minimum job fee that many contractors charge.
Example Scenarios:
Let's look at a few examples using the calculator's default rates:
- Scenario 1: Standard Driveway Cleaning
- Surface Area: 800 sq ft
- Surface Type: Concrete
- Dirt Level: Moderate
- Accessibility: Easy
- Minimum Job Fee: $150
- Estimated Cost: (800 sq ft * $0.20/sq ft * 1.2 dirt multiplier) + $0 accessibility = $192. Since $192 is greater than the $150 minimum, the estimate is $192.00.
- Scenario 2: House Siding Wash (2nd Story)
- Surface Area: 1500 sq ft
- Surface Type: Siding
- Dirt Level: Light
- Accessibility: Moderate (due to 2nd story)
- Minimum Job Fee: $150
- Estimated Cost: (1500 sq ft * $0.25/sq ft * 1.0 dirt multiplier) + $50 accessibility = $375 + $50 = $425. The estimate is $425.00.
- Scenario 3: Small, Heavily Stained Patio
- Surface Area: 200 sq ft
- Surface Type: Concrete
- Dirt Level: Heavy
- Accessibility: Easy
- Minimum Job Fee: $150
- Estimated Cost: (200 sq ft * $0.20/sq ft * 1.5 dirt multiplier) + $0 accessibility = $60. Since $60 is less than the $150 minimum, the estimate is $150.00.
