By late April the pine pollen has laid a yellow film across every drive, rail and length of siding in Gainesville, and the first good wash of the year feels like opening a window. Nelsons Lawn and Power Washing Service LLC does both sides of that — power washing driveways, walkways, patios, decks and house siding, and keeping the lawn itself with mowing, edging, string trimming, hedge trimming, bed maintenance, mulch and pine straw, and leaf cleanup. Concrete coming back two shades lighter under the wand is a satisfying thing to watch, and a cut lawn beside it makes the whole property sit right. Humid Hall County summers grow mildew on north-facing walls, so the washing has its season as surely as the mowing does. From the square out to the lake, the routes run all year.
