Concrete Wall Cleaning

What This Service Involves

Poured concrete walls on the shaded side of a Northwest property turn green with algae long before the pavement does. Blasting a vertical surface with high pressure risks etching, so we rely on a soft-wash approach that lets the cleaning solution do the work. The treatment clings to the wall, breaks down the biological film, and rinses away without leaving wand marks. This keeps foundation walls, basement exteriors, and freestanding walls looking maintained.

Benefits

Clears green algae from shaded, north-facing wall surfaces; Cleans vertical concrete without etching or wand marks; Uses dwelling solution to reach into porous texture; Refreshes foundation and freestanding walls alike; Slows biological regrowth after treatment

Our Process

1) Protect adjacent plantings and cover nearby surfaces; 2) Apply a soft-wash cleaning solution top to bottom; 3) Allow dwell time to break down algae and grime; 4) Low-pressure rinse for an even, streak-free finish

What Affects the Cost

Total wall area and height requiring reach equipment; Extent of algae and biological staining; Texture and porosity of the concrete surface; Landscaping protection needs at the base; Access constraints along the wall line

Best Time of Year

Spring is a strong time to clear the algae that flourished through the wet winter, giving walls a clean start before summer.
