Pressure Washing in Central PA

Pressure washing is one of the busiest scopes we run across Central PA every spring. Winter road-salt spray, spring pollen, and humid-summer mildew coat driveways, sidewalks, and elevations through most of the year, and by late summer mildew on shaded north walls in Harrisburg, Carlisle, and Lancaster is heavy enough that any repaint bonded on top would fail early. Crews adjust pressure and tip size to the substrate so painted brick, cedar shingle, painted wood, stucco, and concrete each get the right approach.

Older Harrisburg rowhomes and Lancaster brick rowhomes tend to have chalky paint and softer joints that will not tolerate maximum pressure, while newer Camp Hill, Mechanicsburg, and Hershey builds can take a more aggressive wash. Cedar shingle facades take a soft-wash chemical approach rather than mechanical pressure to preserve the shingle face. Concrete, pavers, and stamped hardscape each get a different pressure and detergent approach at the estimate.

Most standalone pressure-washing requests here are pre-listing cleanups or pre-paint prep. When the goal is a full exterior repaint, the wash is scoped as the first day of the project so paint bonds to a clean substrate. Our writeup on long-lasting exterior paint treats pressure washing as step one for a reason.
