If you have noticed that your walkway is slippery and/or
unsightly because of algae or mold, it's time to call me. If
your home has a buildup of dirt or spider webs under the
overhang and/or on exterior walls, it's time to call me.
Oil and rust stains on driveways and parking spaces can
also be removed.

Pressure
washed instead of going through the highly priced
process of replacement, resurfacing, or painting:
-- Patio slabs.
-- Sidewalks, walkways, and driveways.
-- Stucco house walls and brick walls.
