WHAT IS SOFTWASHING? Softwashing is similar to pressure washing except it uses a lower pressure that does not damage your housing and roofing materials. Softwashing uses a much lower PSI. It is safer for window seals, paint, vinyl, hardy board, stucco, and brick homes. Softwashing uses a chemical to clean the home, or structure rather than water. This chemical will treat the home's algae and mold growth. It's a much cleaner and brighter look. For overall restoration, protection and satisfaction of your home's appearance.
