I wasn’t sure what to think when I called Perfect Clean, I have a white house which was spotted with black mold, and blanketed with areas of green mold. I didn’t think there was going to be any way to get rid of it and thought I was going to have to replace my siding. I couldn’t have been more wrong. When they were done it literally looked brand new. They covered every inch of my house without leaving a single streak. Very Impressed! Already recommended them to my friends. Thanks Perfect Clean!
