Pressure Washing in Vancouver, WA

Algae grows quickly on sidewalks and walkways here in the Northwest making flat concrete surfaces look old and worn.  We used our 30" surface cleaner to pressure wash the concrete surfaces at this Vancouver home.  The surface cleaner helps keep the dirt off the surrounding areas (like the mahogany fence in the picture) and ensures a uniform cleaning. 

We were asked to come back and chemically treat the roof as well.  More pictures to follow...
