Pressure washing is Gwinnett County's signature reset button. The local grime has three authors working year-round: pine pollen that films every horizontal surface each spring, algae and mildew that feed on humid shade from May through October, and the red-clay splash line that creeps up brick, skirting, and garage aprons after every hard rain. None of it comes off with a hose. All of it comes off in one scheduled visit with the right machine, the right tips, and a pro who knows which surfaces want pressure and which want soft-wash chemistry instead.
Pressure where it belongs, soft wash where it doesn't
Concrete driveways, sidewalks, and pool decks take a surface cleaner and real pressure; that's where the satisfying stripes come from. Siding is a different discipline — vinyl seams, aging paint, and window seals reward low pressure and detergent dwell time, not a cutting jet, and a Gwinnett pro who works houses rather than parking decks knows the difference by feel. Roofs are their own category again: the black streaking on north-facing shingles is algae that wants gentle chemistry, never a pressure tip, and any roof past a careful walk's pitch gets quoted honestly or referred out.
The Gwinnett washing calendar
Smart money washes twice: once after the pollen finally quits in late spring — taking the yellow film, the winter grime, and the first algae bloom in one pass — and once in fall, ahead of holiday guests and cool-season curb appeal. Sellers book a third: nothing photographs a listing in Duluth or Suwanee better per dollar than bright concrete and clean siding. Whatever the season, the visit quotes free.
Who calls for this around here
Subdivision homeowners staring down an HOA letter about the green north wall, first. Then sellers and their agents, landlords between tenants in Lawrenceville and Norcross, and the practical majority who simply notice the driveway has quietly gone gray-brown against the neighbor's fresh-washed white. If a bigger project rides along — a deck that needs boards before it needs washing, paint failing past the point of cleaning — the pro says so plainly and the routing follows Georgia's rules.
