The Roof Wizard washed this huge, 31,000/SF home in Bryn Mawr, PA recently. We softwashed everything from the slate roof, stucco sides, marble railings and fountains, blue stone walkways/patios and even the 2500/SF Guest house. It was our largest residential job ever, both in size and price. It took two crews a full five days to complete. The job was based on a referral from a large commercial project we cleaned last year and will hopefully lead to some more of these monsters.
