"DD Surface Cleaning was very professional and thorough. Our decks were power washed and sealed perfectly and in a timely manner. We are in the process of making another appointment to have our house power washed! I would definitely recommend him for any project, we would not think of hiring anyone else for our projects!"

Pressure Washing FAQs, answered by experts

Whether you need to winterize your pressure washer depends on where you store it. If you can keep it in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, if the machine will be stored in freezing temperatures, any liquid left in the water pump can freeze, expand, and cause severe damage. To prevent this, add antifreeze to keep it in good condition. While some suggest emptying the machine with compressed air, this can be a tedious process that may not fully drain the liquid. Regardless of storage conditions, it is also good practice to empty the gas chamber and refresh the oil before winter storage.

You can get more pressure out of your pressure washer by adjusting the pressure control knob clockwise to increase pressure (+). You can also check your nozzle for debris and clogs and remove anything you find with needle nose pliers. Switch to a nozzle with a lower-degree spray angle or a turbo nozzle to achieve more pressure at the tip. Check for leaks in the hose and connections, and make sure your water supply is offering enough pressure. 

The white nozzle is your best choice for power washing indoors. The white nozzle, or the 40-degree nozzle, comes with a pressure even lower than the standard green nozzle but still has enough force to clean the surface. It works great for painted and wooden surfaces. It also doesn’t damage more delicate materials like ceramic or tiles. However, avoid pressure washing delicate furniture, caulking, and other surfaces that require more tendered touches than regular surfaces.

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. 

A pressure washer’s size or power is measured in pounds per square inch (PSI). The amount of pressure you need will depend on your project and the material you’re washing, but consumer pressure washers range from 500 to 2,400 PSI. Porous materials like brick and stucco should not be blasted with anything stronger than 1,000 PSI, while you can use a PSI of up to 2,400 to clean a vinyl fence.
