There is no denying that a power washer can be an extremely useful tool for the do it yourself home owner. When used properly with the correct cleaners and methods a power washer can clean vinyl siding, stucco, brick, concrete, decks, fences, patios, awnings and more.

It must also be noted that in the wrong hands a pressure washer can be a very dangerous tool. When in the hands of an inexperienced operator a power washing unit can easily damage any of the surfaces mentioned above. The most common cases of damage are caused to vinyl siding, wood decks, asphalt shingles, mortar joints, and even concrete.

The typical reason these inexperienced operators accidentally damage these surfaces is by using way too much pressure. Even small consumer grade pressure washing units put out a couple thousand P.S.I. which is more than enough to cause damage. For most surfaces around the home, except for maybe concrete, you need to change the nozzle at the end of the wand to achieve a lower pressure without sacrificing water flow.
