Every April a fine yellow film settles over Rockdale County — pine pollen on the porch rails, the siding, the drive, the mailbox, all of it. GreenWerks Pressure Washing & Lawn Care LLC shows up with water and pressure and lifts the year off concrete, walkways and house siding until the original color comes back. The lawn side runs right alongside: mowing, edging, trimming, and the drive cleared at the end. Few things are as immediately gratifying as a wet stripe of clean concrete widening across a driveway. With both finished, the whole property looks like somebody lives there on purpose.
