There are many surfaces that are safe for pressure washing, including: concrete, brick, stone, pavers, metal, some wood and synthetic materials. However, it’s important to note that not all surfaces are safe for pressure washing. For example, delicate surfaces such as painted surfaces, stucco, and some types of siding may be damaged by the high pressure and force of the water. That’s why it’s crucial to consult with a professional exterior cleaning company before attempting to pressure wash any surface on your own. They can advise you on the best methods and techniques for safely cleaning your specific surfaces.
