Excel Eco Clean did an absolutely wonderful job cleaning the lichens off my brick house as well as cleaning the green/moss off my son's white vinyl siding on his home. In addition to cleaning my brick they cleaned the cement patio and sidewalks. They are 40 +years old and now look like new! In addition, the white gutters were sprayed and are now bright white again. At my son's home the green mold had advanced up to the second story on the west and north sides. After being sprayed the mold actually slid off the vinyl, it was amazing. His house is bright white again. I am highly recommending Excel Eco Clean.
