The cost to pressure wash a house ranges from $100 to $750, depending on the location, size, and height of your house. Power washing, on the other hand, costs from $250 to $400 per project, on average. Other cost factors include the accessibility of some areas of the house.
The main difference between pressure washing and power washing is that power washing uses hot water and pressure washing does not. Pressure washing uses only the water from the outside hose connection. Heated power washers tend to cost more and are more commonly used by professionals. Hot water with special cleaners is better suited to more complex or challenging cleaning tasks such as removing grease or oil from a concrete slab. In most cases, pressure washing your driveway should not require heat or powerful cleaners.
Yes, pressure washing companies typically use your home’s water supply from the water spigot outside your house. While arrangements can be made with the pressure washing company to supply its own water, it’s very rare. Unless the company is already set up to supply its own water, this will likely incur additional costs for the company to fill a tank and haul it.

It’s best to pressure wash in the spring, but it’s okay to pressure wash in the spring or the fall. Dirt, grime, and mildew can gather and reappear over the winter, so pressure washing only in the fall may not be worth the effort. Instead, pressure washing in the spring cleans areas around the house for the rest of the season. You can always touch up again during the summer or fall to make spring cleaning a little easier.
