The average cost to pressure wash a house is around $310, with typical prices ranging from $200 to $420. However, the total cost can vary widely, from $200 to $750. Power washing, which uses heated water, may cost between $250 and $400 per project, with an average of $200 to $300 for a 2,000-square-foot home.

Key factors that influence the final price include:

• The size and height of the house (a multi-level home costs more than a single-story one).

• The complexity of the job and accessibility of certain areas.

• Geographic location.

• Equipment and hourly labor costs.

Hiring a professional is often recommended as they bring their own equipment and cleaning solutions. Experienced professionals know how to complete the job effectively without causing damage to your siding, gutters, or landscaping, which can be a risk with high-powered water jets.

On average, pressure washing a house can take anywhere from 30 minutes to three hours. The time frame to pressure wash or power wash your home, fence, or other property depends on the size of the project and the complexity and accessibility of the areas that need cleaning. Part of the time required to complete the job includes setup and removal of equipment needed. A two-story house with a steep roof may require working from scaffolding or a ladder, likely adding to the time required to finish the project. 

The ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.

You should never use bleach in a pressure washer. While bleach is effective at killing mold and mildew, it is a potent chemical that can corrode the machine's seals and nozzles, destroying it from the inside out. Additionally, pressure washing with bleach sprays the chemical into the air, which is dangerous if inhaled and can kill nearby plants, flowers, or harm animals that ingest it. If you need to remove mold or mildew, it is best to hire a professional who will use a safe and effective cleaning agent.
