How Much Does It Cost to Power Wash a House?

May 9, 2025

Power washing is an essential part of home maintenance that keeps your property looking fresh and prevents long-term damage from mold, mildew, and dirt buildup. But one of the most common questions homeowners ask is, “How much does it cost to power wash a house?” The answer varies based on several factors, but hiring a professional like Master Blaster Pressure Washing ensures that you get quality results without damaging your home.

Average Cost of Power Washing a House

The cost of power washing a house typically ranges from $250 to $600, with the national average falling around $350 to $400. Several factors influence the final price, including the size of your home, its exterior materials, and the level of dirt buildup.

At Master Blaster, we base our pricing on the square footage of your home to ensure fair and transparent pricing. Here’s a general breakdown:

  • Small homes (1,000-1,500 sq. ft.) – $200 to $300
  • Medium homes (1,500-2,500 sq. ft.) – $300 to $450
  • Larger homes (2,500-3,500+ sq. ft.) – $450 to $600+

Factors That Affect Power Washing Costs

Understanding what influences the cost of power washing can help homeowners budget appropriately.

1. Home Size & Square Footage

Larger homes require more time, water, and cleaning solution, leading to higher costs. A two-story home will also cost more than a single-story home due to the additional labor and safety precautions required.

2. Type of Siding Material

Different exterior materials require specific power washing techniques:

  • Vinyl Siding: Easy to clean but requires proper detergent to avoid oxidation stains.
  • Brick: Requires a softer wash method to prevent mortar damage.
  • Stucco & Wood: Need low-pressure soft washing to prevent surface damage.

At Master Blaster, we adjust our pressure settings and detergents accordingly to avoid any damage while ensuring a deep clean.

3. Level of Dirt & Mold Buildup

A house that hasn’t been cleaned in years will require stronger detergents and extra time to remove built-up grime, mold, and algae. Homes in humid climates or near wooded areas often accumulate more organic growth, leading to higher cleaning costs.

4. Additional Services

Power washing isn’t just for siding! Many homeowners bundle services to save money. Master Blaster offers:

  • Roof cleaning – $250-$500
  • Driveway cleaning – $150-$300
  • Deck & patio washing – $100-$250
  • Gutter cleaning – $75-$200

Bundling multiple services often results in discounts, making it a cost-effective option for homeowners.

DIY vs. Hiring a Professional Power Washing Service

Some homeowners consider renting a power washer and doing the job themselves. While this may seem like a cost-saving option, there are several risks involved:

1. Potential for Damage

Without proper training, using high-pressure water can strip paint, damage siding, or force water behind your home’s structure, leading to mold and rot issues.

2. Incorrect Cleaning Solutions

Using the wrong cleaning detergents can cause oxidation stains on siding, kill plants, or fail to remove mold effectively. At Master Blaster, we use commercial-grade detergents that clean thoroughly while protecting landscaping and exterior surfaces.

3. Safety Risks

Power washing involves climbing ladders and handling high-pressure equipment. A professional crew has the necessary safety gear and experience to prevent injuries and property damage.

Best Time of Year to Power Wash Your House

Timing plays a role in achieving the best power washing results. The ideal time to schedule a professional cleaning is during spring and early summer when mild temperatures allow for quick drying. Fall is another great time to wash your home before winter weather sets in and causes dirt buildup to harden.
