Mix water and cleaning detergent in a bucket according to the manufacturer’s instructions. Add one part bleach for every nine parts detergent in the bucket. After you’ve prepped the exterior of your house, set your pressure washer up for a thorough job. So, investing in one is a good idea if you plan to use it regularly – and you should. The power of your pressure washer is measured in PSI (Pounds per Square Inch) and GPM (Gallons Per Minute). A machine with a higher GPM is more powerful than a machine with more PSI and lower GPM.

We never recommend using a pressure washer while you’re perched on a ladder because blowback could throw you off balance. The powerful stream of water can also loosen roof shingles, and if your shingles are asphalt, it can strip them of the embedded granules that help extend the life of your roof. Attach the garden hose to the pressure washer and attach the spray nozzle labeled for applying detergent. The water pressure is what cleans the surface, but there is a delicate balance between using the right pressure and using so much that you cause damage. These washers can be adjusted to the exact pounds of pressure per square inch (PSI) required for the surface in question. Different levels of dirt or debris may require adjustments to the PSI.

How much does it cost to pressure wash the exterior of a house?
Electric models, on the other hand, are less powerful but more convenient for smaller tasks. Models like the Karcher K2 below are easier to handle and ideal for those who are new to pressure washing. Choosing the right equipment for pressure washing your house is crucial. It’s not just about power, but also about suitability and safety. Rent a washer that produces at least 2,000 psi (pounds per square inch) of pressure. It’ll cost about $70 to $100 per day, and expect to keep it for a full day.
Dirty or Discolored Siding
This will help ensure that the cleanser you use won’t dry on foliage and leave burn marks. If your project takes longer and the plants start to dry off, you may need to water them again. Depending on the chemicals you’re using, however, you may instead want to protect the plantings with a tarp. What’s more, stains like rust, acorns, and fertilizer are permanent.
Safety Tips
Over time, this debris builds up and can cause staining or discoloration of the exterior. If the debris stays in place long enough, it can even cause uneven fading of the siding. Regular cleaning will keep the home’s exterior looking fresh and new and will actually prolong the life of the siding.
Choosing a Pressure Washer
Pressure washing a home is risky if you do not follow the proper safety measures, and can be quite demanding physically. If it has been a long time since you last pressure washed your home you’re probably in for a lot of scrubbing by hand, and hours of reaching high and low on a vertical surface. If your home is taller than one story and you’re not up for standing on a scaffolding, you might consider hiring a pro for the job. For single-story homes, however, the steps below will guide you through how to pressure wash a house—and boost your curb appeal.
It’s a pressure washer with a GPM for clearing debris and a PSI for removing grime. Do not be deterred by its diminutive size, as it packs a mean punch. A 1.1 GPM rating on this washer means that it is designed to remove tough stains, and it did. I was able to easily remove mold and mold “grout” lines from my patio with the 25 degree moderate pressure nozzle.
Difference Between Pressure Washing and Power Washing
We asked the CR experts who oversee our pressure washer ratings to weigh in on a range of common surfaces. Electric pressure washers can be very powerful, so it’s important to use a strong and durable extension cord. Never use an extension cord that doesn’t have an adequate gauge rating or is otherwise damaged, as this could potentially lead to electrocution.
To arrive at the average costs in this article, editorial team members surveyed a seven providers on national and local levels. All averaged figures were correct at the time of publication and may be subject to change. You’ll want to remove this before painting to ensure the new paint adheres well.
Professional contractorswho move a lot faster than I do and often work in squadswash and rinse from the top down. Since I'm not a professional, my goal is to take my time, work safely and get the house clean enough so that it won't need to be done again for at least another year, and maybe longer. The widest nozzle draws detergent from the receptacle; if you're washing a vertical surface (like a wall), go from bottom to top. To power-rinse, switch to the 25-degree nozzle (green) and sweep it from the top down in overlapping passes, avoiding windows and frames.
It’s a great way to tackle tough stains and spills that are difficult to get rid of with traditional cleaning methods. The average cost to power wash a two-story house is $120 to $1,600, depending on the exact square footage, cleaning method, and level of dirt. A washer with a PSI rating of 1,000 to 1,500 is usually quite sufficient for washing siding. If you have a two-story house, a high-volume gas pressure washer fitted with a special nozzle will allow you to clean the upper areas while standing on solid ground.
When pressure washing, it’s important that you wear the proper safety equipment. This means eye protection and heavy-duty work gloves to protect against debris and flying objects. Ensure you adequately prepare the cleaning area before you get to work. This means clearing away items like patio furniture and window screens on or around the surface that you’re planning to wash. Also, make sure that any electrical outlets and light fixtures are covered or turned off, as the high-pressure water can easily damage them. Power washing the exterior of your house is an excellent way to prime surfaces for paint, stain, or other finishes.
By following these steps, you can ensure a thorough clean that rejuvenates your home’s exterior, all while keeping things safe and efficient. By following these steps, you can set up your pressure washer effectively, ensuring a smooth and safe cleaning process. If you’re planning to buy a pressure washer, talk to experts at your local hardware store.
If this distance allows you to remove dirt without damage, maintain it. If dirt isn’t coming off, move closer in increments of 4 to 6 inches, stopping each time to gauge the cleaning power and check for damage. For harder surfaces and a higher psi, use a 15-degree spray nozzle. For softer surfaces and a lower psi, choose a 25- or 30-degree nozzle. If you’re washing a two-story structure, begin at the top and work your way down; you’ll probably need to attach the extension wand to reach the upper floor. So, with three key features in mind, selecting an electric pressure washer should be based on your intended use.
