Our Austin Stone house had quite a bit of black mold growing on the north and west sides, plus gutters and eaves, etc. had collected a lot of dirt/dust over several years. The Patriot team spent one day cleaning the entire outside of the house, plus Austin Stone plant bed borders, mailbox, driveway, sidewalks, pool deck, gutters and eaves. House is 25 years old but now looks like brand new. All dark areas are completely clean and no trace of mold anywhere. Great job.
