90% of all pressure washing service accounts are residential.  A handful of jobs each year are commercial accounts.  La Posada Senior Facility in Santa Cruz has been a client of ours since 2002.  We wash ALL the aggregate sidewalks around the entire property, including the swimming pool area and the front entrace.  When concrete gets mossy, it can be extremely slippery when wet.  Slippery concrete is not something you want around a senior facility.  We maintain these grounds 2x per year.  One nice old lady has begun calling me Mr. Neverstopper.  So cute!!
