Cave pressure washing
Astoria sidewalks get slick. Moss, algae and mildew grow on concrete that stays shaded and damp, especially through the winter. A dirty walk is not just an eyesore, it is a slip hazard.
Cave pressure washing uses a surface cleaner and controlled pressure to strip the green and black buildup off concrete sidewalks, entry walks and paths. We keep the edges clean and avoid blasting mulch and dirt into beds. The result is a brighter, safer walkway.
