What Size Pressure Washer For 2 Story House?

Size matters significantly when it comes to pressure washing a two-story house. A pressure washer with insufficient power won’t effectively eliminate dirt and grime, while an excessively powerful one could potentially harm your home’s siding. The optimal size for a two-story house typically falls in the range of 3,000 PSI (pounds per square inch) and 2.5 GPM (gallons per minute).
It’s important to note that different types of siding may require different levels of pressure. For example, vinyl siding can typically be cleaned with lower pressures than wood or brick siding. Be sure to check the manufacturer’s recommendations before starting any cleaning.

In addition to PSI and GPM, consider the type of engine on your pressure washer. Gas-powered engines are typically more powerful but also louder and produce emissions, while electric engines are quieter but less powerful.

How To Pressure Wash A 2 Story House (step by step)

Before delving into the meticulous steps for pressure washing a two-story house, it’s paramount to prioritize safety. Ensure you possess a secure and reliable ladder, and don the necessary protective gear, including safety glasses, gloves, and non-slip footwear.

Commence by preparing your pressure washer. Top off the fuel and water tanks, if required. Connect the hose securely to both the machine and the spray gun. Before initiating the machine, ensure the water supply is turned on.

Begin at one corner of your home’s exterior wall while standing safely on a ladder or scaffold tower if necessary. Use a low-pressure nozzle for delicate surfaces like wood siding or high-pressure nozzle for tougher surfaces like concrete driveways.

Work from top to bottom, moving across each section evenly in straight lines until you reach another corner. Take breaks every so often to avoid fatigue.

Once finished with one side of your house, move onto another side in similar fashion until all sides are complete.

Turn off your pressure washer carefully by following manufacturer instructions and store it properly after use ensuring all hoses are disconnected completely.

Tips For Pressure Washing Various House Siding Types

When embarking on the task of pressure washing a two-story house, it’s crucial to recognize that not all types of siding are equal. Diverse siding materials necessitate distinct approaches and varying levels of pressure to ensure a thorough clean without causing any harm.

For vinyl siding, it’s advisable to employ low to medium pressure with a broader nozzle spray pattern. Commence cleaning from the top and proceed in manageable sections. Avoid spraying at a direct angle, as this can force water underneath the siding, potentially resulting in damage.

Brick homes, on the other hand, can tolerate higher pressure, but caution is paramount around mortar joints, which are susceptible to damage. Exercise care when cleaning painted brick, as high-pressure water streams may strip off the paint, leading to unintended consequences.

Stucco is another material that should be approached with care, using only low or medium pressure settings. Angle the spray downward from the top for best results and avoid hitting any areas where stucco has cracked or chipped.

Wooden siding requires even more caution than other materials, using only low-pressure settings starting from the bottom up to prevent streaking or splintering.

By following these tips for various house siding types, you’ll ensure that your home gets cleaned thoroughly without causing any unnecessary damage in the process.

What is the average height of 2 Story House?

The average height of a 2 story house varies depending on the region and architectural style. In general, a 2-story building is designed to be taller than a single-story structure.

In the United States, the average height of a 2 story home ranges from 20 to 25 feet. However, some homes can reach up to 30 feet or more in areas with higher ceilings or sloped roofs.

Other factors that affect the height of a 2 story house include its foundation type and materials used in construction. For instance, homes built on elevated foundations may appear taller compared to those built on standard concrete slabs.

Additionally, architectural styles such as colonial and Victorian often feature tall windows and ornate details that add extra height to the structure.

When choosing a pressure washer for your two-story home, it’s important to consider its height along with other factors such as siding material and water pressure requirements.


How much PSI do i need to pressure wash a house?

When it comes to pressure washing a house, you may wonder how much PSI is needed. The answer depends on the type of surface being cleaned. For example, brick or concrete can handle higher PSI than delicate surfaces like wood or stucco.

Generally speaking, a pressure washer with 2000-3000 PSI is adequate for most home cleaning projects. However, if dealing with tough stains and grime on a large area such as driveways or decks, one may require more power up to 4000PSI.

It’s important to note that using too high of a PSI can damage certain materials and surfaces including paint jobs and cause other costly damages. Therefore following manufacturer recommendations is highly recommended.

Additionally, homeowners should choose the appropriate nozzle tip for their specific cleaning needs which will improve efficiency while also preventing accidental damage due to improper spray angle selection.

Understanding the right amount of pressure required when pressure washing your house can help you avoid damaging your property while getting optimal results.

how much time does it take to pressure wash a two story house?

The amount of time it takes to pressure wash a two-story house can vary depending on several factors. The size of the house, type of siding, and level of dirt buildup are all important considerations.

Generally speaking, a small to medium-sized two-story home with vinyl or brick siding could take anywhere from 2-4 hours to pressure wash thoroughly. However, if the home has wood or stucco siding or is especially large, it could take longer.

It’s important to note that rushing through the job will result in an incomplete cleaning and potentially damage your property. Taking your time and being thorough will ensure that you get the best results possible.

Another factor to consider is whether you’re using a gas-powered or electric-powered pressure washer. Gas-powered models tend to be more powerful but may take longer due to refueling needs.

In summary, there’s no one-size-fits-all answer when it comes to how long it takes to pressure wash a two-story house. It’s crucial for homeowners not only focus on completing the task quickly but also doing so safely while achieving desirable results.


To sum it up, pressure washing a two-story house can be quite a task, but the right pressure washer and technique can make it a breeze. When choosing the best size pressure washer for your 2 story house, consider the PSI and GPM required to get your job done effectively and efficiently.

Always remember to follow safety precautions before starting to power wash your house. Pay attention while using ladders or any other equipment that could lead to falls or injuries. Moreover, take proper steps to protect delicate areas such as windows and landscaping from damage.

With all these things in mind, you are now ready to tackle any dirt or grime on your two-story home’s exterior with confidence!
