Pressure washing is a fantastic way to transform a surface from old to new. It easily wipes out dust and stains, making it a great method for cleaning dirt-prone areas like a concrete driveway. In some cases, however, pressure washing can do more harm than good, as the extreme power can be especially damaging to certain surfaces. It should only be used on materials that can withstand such a high intensity, and most home sidings are simply not durable enough to survive a pressure wash.
While every home exterior is unique, most have siding that isn’t suitable for extreme pressure. Many siding panels can be knocked loose, and the harsh stream can dig holes and grooves into a variety of materials. Wood paneling and cedar shake siding are a definite no-go, and vinyl siding is at risk for being warped or dented. Even brick walls with old mortar can be destroyed, compromising the stability of the home. Painted areas can be ruined as well, leaving behind chipped or faded color. In the case of certain older houses, the painted exterior may contain led, which is a serious health hazard if the paint chips are scattered onto the property or make their way into the soil. Aside from damaging siding and chipping paint, pressure washing can also lead to internal home issues. With such a forceful spray, water can be shot into tiny cracks and crevices, making its way into the foundation of the house. Trapped moisture introduces a variety of problems on its own, and can negatively affect the structure, insulation, and longevity of your home.
If you’re looking to have your house washed, always consult with a professional service about the right method for cleaning. Licensed experts are highly knowledgeable and properly equipped to get the job done safely, saving you from the worry of any accidental damage.
