Retaining Wall Cleaning

What This Service Involves

Retaining walls in hilly Washington neighborhoods hold back constantly damp soil, which pushes moisture and mineral staining through the face. That combination breeds moss in the seams and leaves dark streaks down the surface. We treat the biological growth and address the soil-driven discoloration with methods matched to the wall's construction. The finished wall frames a terraced yard cleanly instead of fading into the hillside.

Benefits

Removes moss lodged in seams and mortar lines; Addresses soil and mineral staining pushed through from behind; Matches the method to poured, block, or segmental walls; Restores definition to terraced landscaping; Reduces slick growth on wall caps and steps

Our Process

1) Clear vegetation creeping onto the wall face; 2) Treat moss and algae with a targeted solution; 3) Clean the face and seams at appropriate pressure; 4) Rinse and flush residue away from the base plantings

What Affects the Cost

Linear footage and height of the wall; Construction type and joint detailing; Severity of moss and mineral staining; Slope access and staging difficulty; Landscaping density along the wall

Best Time of Year

Early summer, once the ground begins to dry, reduces the moisture feeding wall growth and helps the cleaning last longer.
