Pressure washing offers a great way to quickly blast dirt and grime from exterior surfaces, such as your house itself, driveways and decks. This process can quickly and efficiently freshen up a surface.

Pressure washing basically uses a water pump and electric or gasoline motor to power a high-pressure hose and sprayer to generate an extremely powerful spray. In some cases, detergents or other chemicals are used to enhance the effect.

Sometimes the term is used interchangeably with “power washing,” but they’re not quite the same thing. They use very similar equipment, but tools that power wash a home heat the water to loosen up dirt or grease.

But, you should take great care with either. Pressure washing and power washing are potent tools that are best used by the hands of professionals.

Power Washing Costs

The cost to or power wash a house varies based on size. For a smaller home, you’ll pay around $100 for this job. Larger homes could go as high as $380.

You can use pressure washing on other exterior surfaces such as decks or driveways. You’ll pay between $80 and $200 to pressure wash a driveway. The cost to power wash a deck runs between $250 and $500. Professionals report that you’ll pay about $2 per square foot on a deck.

Hiring a power washing service

When you hire a pressure washing or power washing service, make sure they’re up to date on EPA regulations regarding runoff water and environmentally-safe chemicals. The EPA can hold a property owner responsible if cleaning chemicals are allowed to discharge into the drainage system.

Ask if they have experience with your type of house. Some power washers add chemicals to the spray to clean more effectively. The specialized chemical knowledge is one big reason it’s wise to hire a pro rather than do it yourself. 

Verify that they carry their own insurance, to cover any damage to your home that may occur.

If your house’s exterior contains lead paint, the work needs to be done by an EPA-certified specialist who can safely wash the exterior without contaminating the nearby area.
