Power Washing Your Home's Exterior

by / Monday, 05 March 2012 / Published in Greenway Services

So you may have decided that you would like to go ahead and power wash your house.  There are a few things to keep in mind when either buying or renting a power washing machine. Although these may be convenient to use, keep in mind that they can be quite dangerous as well. Power washers come with a list of instructions. Although you may think that you know what you’re doing, take the time to read the instructions all the way through. Never point the nozzle at anyone or any animal. Make sure all of the connections are tight before turning on the nozzle, otherwise water will go flying everywhere and could cause further damage.

The pressure of the water coming from a power washer can range up to 4,000 pounds per square inch (psi). If you are using the power washer to clean your house, you will not want to use more than 1,000 psi. More pressure than this can actually get behind the wood and damage the house, causing mildew and mold, which is the opposite of what you’re trying to do.

If your home was built before 1978, chances are that the paint contains lead.  If you power wash your house, the lead could runoff into the surrounding environment and contaminate the ground.  If this is the case, we strongly urge you to hire professional Cincinnati house painters who have a license to remove lead based paints and who specialize in eco-friendly practices.

If you do decide to rent the power washer, it will probably cost around $40-$80 a day.  Be sure to use the appropriate safety equipment, including earplugs, gloves, and safety glasses. When you turn on the power washer, you will probably lurch backwards a little. Also the ground around you will become soaking wet.  If you’re up on a ladder or on the roof, use extreme caution as this can cause you to fall backwards or off the ladder entirely.  Your number one concern should be your safety, not the cost. As you are power washing your home, never spray near electrical or telephone wires, or other wires that may run into your home. Never spray satellite or TV dishes. Keep your eye out for animal nests including bee, hornet, and wasp nests.  Also, you should never use the power washer if there’s lightning.
