How Long Does It Take To Pressure Wash A House?

Pressure washing provides a rapid solution for removing stubborn dirt and grime buildup. Understanding how long it takes to pressure wash a house is essential for this home maintenance task. In this guide, we’ll delve into the details of pressure washing, exploring its methodology and duration to help simplify the process.

How Long Will It Take To Pressure Wash My Home?

It typically takes three to five hours to pressure wash a small to medium-sized house, including the time needed for basic preparation and cleaning steps. However, the exact duration can vary depending on several factors:

Factors affecting pressure washing time:

  • Size of the house: Larger homes will naturally require more time to pressure wash than smaller ones.
  • Number of stories: Homes with multiple stories will generally take longer to pressure wash, as each level needs to be cleaned individually.
  • Number of helpers and experience: The presence of additional helpers and their experience level can significantly impact the time needed for pressure washing. Professional services may complete the task more efficiently than DIY attempts.
  • Frequency of professional cleaning: If the home has been regularly maintained and professionally cleaned, it may require less time for pressure washing. However, if there is a buildup of dirt, algae, or other contaminants, additional time may be needed to achieve satisfactory results.
  • Type of siding: Different siding materials require varying levels of care during pressure washing. Delicate materials may need extra attention and time, while others, such as vinyl siding, can withstand higher pressure.
  • The shape of the home and surrounding landscapes: The architectural features of the home, such as angles, corners, and hard-to-reach areas, can affect the time required for pressure washing. Additionally, the presence of trees or landscaping elements may require extra care and time to work around.

Does Pressure Washing A House Make A Difference?

Yes, pressure washing can make a noticeable difference in the cleanliness and appearance of a house. Using high-pressure water spray, pressure washing effectively removes dirt, grime, mold, and other stubborn stains from surfaces such as walls, driveways, and decks. This method offers a time-saving solution for cleaning large areas efficiently, ultimately enhancing the overall curb appeal and maintaining the integrity of the home’s exterior. However, it’s essential to use caution and follow proper techniques to avoid any potential damage to surfaces or injuries during the process.

How Often Should Your House Be Pressure Washed?

The ideal frequency for pressure washing your house varies depending on the type of siding and the presence of dirt, mildew, or other contaminants. Generally, homeowners with vinyl, metal, or composite siding should aim to pressure wash their homes at least once a year. This regular cleaning helps prevent the buildup of dirt, grime, mold, and algae, maintaining the appearance and integrity of the siding.

For those with wood siding, the need for pressure washing is more situational. Pressure-washing wood siding is recommended only when there is visible dirt or mildew buildup. Keeping an eye on the condition of the siding and addressing any signs of dirt or mildew promptly can help prevent damage and prolong the lifespan of the wood.

Additionally, environmental factors such as climate, exposure to pollutants, and proximity to trees or vegetation can influence the frequency of pressure washing. Homes located in humid or rainy climates may require more frequent cleaning to prevent mold and mildew growth, while those in dryer climates may need less frequent maintenance.

Can You Pressure Wash a Roof?

Yes, you can pressure wash a roof. This is typically referred to as “roof washing.” However it’s important that the equipment and output (such as PSI) is taken into consideration when pressure washing a roof. It’s also important to make adjustments based on the type of roof – such as traditional shingles or clay tiles.

Oftentimes, a roof does not need high-pressure output to effectively clean it. Using a pressure washer with a low-pressure nozzel/lower PSI setting – matched with the proper chemicals, is typically enough to effectively rid the roof of stains and plant growth.

Hiring a professional with experience and knowledge in roof cleaning is often the safest and most reliable solution. Professionals can assess the condition of your roof, choose the appropriate cleaning methods, and ensure thorough cleaning without causing damage.


Understanding how long it takes to pressure wash your house is crucial for planning and maintaining a clean exterior. Pressure washing offers numerous benefits, from removing stubborn dirt to enhancing curb appeal. It’s also important to know which areas you should and shouldn’t pressure wash to avoid damage. With the expertise of professionals, you can trust that your home will be spruced up efficiently and effectively while safeguarding its integrity.
