Can You Pressure Clean the Inside of a House?

Pressure cleaning, often referred to as power washing, is a popular method for deep cleaning outdoor surfaces such as driveways, decks, and sidings. However, homeowners often wonder if this powerful cleaning tool can be used indoors. In this comprehensive guide, we’ll explore the feasibility, precautions, and alternatives to using a pressure cleaner inside your house.

Understanding Pressure Cleaning

Before diving into the indoor use of pressure cleaning, it’s essential to understand what it entails. Pressure cleaning uses high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings and vehicles. It’s particularly effective for tough outdoor cleaning tasks.

The Risks of Indoor Pressure Cleaning

  1. Water Damage: The most significant risk of using a pressure cleaner indoors is water damage. The high pressure can force water into wall cavities, under flooring, and into electrical outlets, leading to potential mold growth and electrical hazards.
  2. Physical Damage: The intense pressure can damage delicate surfaces such as drywall, paint, and finished flooring. It can strip paint, dent softer materials, and ruin finishes.
  3. Safety Hazards: Using a pressure washer indoors poses significant safety risks. The force of the water can cause physical injury, and the spray can dislodge debris at high speeds, potentially causing harm.

When Is It Feasible?

In some scenarios, pressure cleaning indoors might be feasible, such as in an unfinished basement, garage, or industrial setting where surfaces are made to withstand high-pressure water and proper drainage is available. However, it’s crucial to assess the risks and take necessary precautions.

Alternatives to Pressure Cleaning Indoors

  1. Steam Cleaning: For deep cleaning without the risks associated with high-pressure water, steam cleaning is an excellent alternative. It uses vaporized water to clean, disinfect, and deodorize surfaces, making it safe for indoor use.
  2. Manual Scrubbing: Sometimes, traditional elbow grease is the best approach. Manual scrubbing with appropriate cleaning solutions can be effective, especially for delicate surfaces.
  3. Hire Professionals: For tough indoor cleaning jobs, consider hiring professional cleaners. They have the right tools and expertise to clean effectively without damaging your home.


While pressure cleaning is an effective method for outdoor cleaning, its application inside a house is fraught with risks and is generally not advisable. For indoor cleaning, safer and more suitable methods such as steam cleaning or professional services are recommended.
