Surfaces That Should Never Be Pressure Washed
While pressure washing is a powerful cleaning method, it is not suitable for all surfaces. The high-pressure water can cause damage if used improperly. Here are some surfaces that should never be pressure washed:
Vinyl Siding
- Why? The force of the water can strip away the paint or protective coatings and force water behind the siding, leading to mold and mildew growth inside your walls. Soft washing is a safer option for vinyl siding.
Aluminum Siding
- Why? Pressure washing can dent aluminum siding and cause the paint to chip or peel, potentially leading to rusting and deterioration.
Asphalt Roofs
- Why? The intense pressure can strip away the protective granules from asphalt shingles, drastically reducing the roof’s lifespan. A soft wash method is much safer for this type of roof to remove moss and algae.
Old Mortar or Brick Surfaces
- Why? High-pressure water can erode old mortar between bricks, causing structural damage and loosening bricks. It’s better to use gentler cleaning methods on aged brick or stone.
Windows & Glass Surfaces
- Why? The high pressure can crack or shatter glass, especially older windows or those with pre-existing damage. Lower pressure or manual cleaning is best for glass.
Painted Surfaces
- Why? If not handled properly, pressure washing can strip paint off surfaces like wood, metal, or concrete, ruining the finish and requiring repainting.
Stained Wood
- Why? High-pressure water can strip away wood stain or damage the wood fibers, leading to splintering and a need for refinishing.
Electrical Panels and Meters
- Why? Spraying high-pressure water on electrical components can cause malfunctions, short-circuits, or dangerous situations like electrocution.
