One of my son-in-laws recommended I find a soft wash business to wash the white brick on my 72 year old house.  When Wayne McKowen at Revive SoftWash cleaned my neighbor's house and I could see the results, I contacted him.  I wish I had taken before and after pictures, as it was an amazing transformation after treating, especially on the north side of the house that had a lot of mold in the brick.  He also soft washed two other buildings, an office, and a workshop on my property, plus all the concrete surrounding the house and out buildings.  I would definitely recommend Wayne McKowen and Revive SoftWash.
