We have a white, 7-year old, two story (with dormers) home. It was starting to look a bit dingy, with some green algae on the back of the house. Brian and Tim washed the house and treated the roof shingles for mold, in a professional and efficient manner. The house looks like new and we couldn't be happier. Also, the price was very reasonable - so much so, that I believe that I will get the house washed every 3 years or so.
