This is either mold mildew or algae, this grows on most homes and should be treated with soaps and detergents. Do not hire a pressure washer to blast it with pressure. Applying high pressure to your siding can cause permanent damage.
Power washing siding is never the most effective way to clean, people always ask why? Well when applying 4000 pounds of pressure to a plastic siding the outcome is never good. Call us today and get more information about our cleaning process.
We work with a passion of taking challenges and creating new ones in the CLEANING sector.
