This homeowner called us to Powerwash algae growing on a brick wall in Farragut, Tn. This home was going on the market the following week, so we had to clean it up before the realtor took pictures. The house was covered in spider webs, and the retaining walls had heavy algae build up from years of neglect.
We applied soaps with an algaecide to help kill the algae that was growing on the walls due to high levels of moisture from a heavy rain season and virtually no sun around the backside of the home. We then used a power washer to blast away the mold and algae, then finished up with a post-treat of our algaecide to slow down future growth.
