Pressure-wash grime off of your house, decks, driveway

- By Paul F. P. Pogue Angie’s List

Pressure-washing offers a great way to quickly blast dirt and grime from exterior surfaces, such as your house, 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.

However, you should take great care with both. They are potent tools that are best used by the hands of profession­als.

Pressure-washing costs

The cost to pressure- wash or power-wash a home 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. Pressure-washing a deck or patio will cost between $250 and $500. Profession­als report that you’ll pay about $2 per square foot on a deck.

Hiring a powerwashi­ng service

When you hire for this work, 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. You want to be sure they know which chemicals to use and in what quantity for your specific job.

Some companies use biodegrada­ble solutions that won’t damage plants or soil and don’t leave behind a residue. 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.

Most profession­als suggest you avoid power-washing siding. Siding is particular­ly vulnerable to damage, and the vents in most siding can allow water to get caught in between the siding and the home, causing

wood rot.

This is a case where it’s best to rely on a profession­al who has the expertise to use the right pressure settings and can identify if your siding is easily damaged.

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.
