Can a pressure washer really damage your home or property? The answer is that a pressure washer can absolutely do damage if not used properly. The most common occurrence of damage is caused by using too much water pressure. Most people believe that high pressure is what does the cleaning after all it is called a pressure washer.

The truth is that most pressure washers, even the consumer grade washers sold at the big box stores, simply put out too much pressure for pressure washing decks and most other exterior cleaning projects around the home. The exception would be concrete but care still must be taken to avoid damage.

The proper way to clean a deck or your homes siding is by relying on the appropriate cleaners to do most of the work so that high pressure is not necessary. Too much pressure can force water behind vinyl siding which can cause water damage. On a wooden deck, excessive pressure can easily fur the wood leaving unsightly wand marks and scars which will show through the sealer and take away from the beauty of the deck.

High pressure should never be used on asphalt shingles, doing so will remove the granules and lessen the longevity of the roof. If you are not experienced using a power washer it may be best to hire a professional cleaning company to do the work for you, just make sure they use low pressure methods.
