Organic growth is visible
Green or dark buildup is spreading across shaded concrete, block, brick or rendered sections.
Retaining walls often sit in damp, shaded areas where soil splash, organic growth, water runoff and atmospheric grime build quickly. We select a method that accounts for the wall material, drainage, staining and surrounding garden.
These are some of the common signs that it may be time to assess the surface and recommend an appropriate approach.

Green or dark buildup is spreading across shaded concrete, block, brick or rendered sections.

Dark streaks, soil splash and repeated water movement are leaving the wall uneven or stained.
The retaining wall can be assessed alongside nearby paths, driveways or garden-area cleaning for a coordinated result.
A considered process built around your home and its different exterior surfaces.
We identify the wall material, finish, drainage, structural condition and stain type, including organic growth, soil splash, mineral marks and repeated water runoff.
We generally begin with an appropriate softwashing mix and controlled rinsing. Where deeper staining remains, a carefully selected acid wash may be tested and used only on a compatible surface.
We inspect the wall, surrounding garden and runoff areas with you, explain any permanent mineral movement or material limitations and confirm the completed result.

Some deeper marks may need more than softwashing. After testing, a carefully selected acid wash may be considered for a compatible masonry surface, but permanent mineral movement may only improve.
No. Rendered, painted or weakened finishes require a lower-pressure approach. Pressure, chemistry and agitation are selected for the actual wall material.
Yes. Plant protection, runoff control and the surrounding soil form part of the cleaning plan, particularly when stronger stain treatments are being considered.
We explain any property-specific preparation during quoting. This may include clearing access, moving fragile items, closing windows or isolating water systems, depending on the service.
Yes. Compatible services can be included in one quotation when access, timing and surface conditions make a coordinated visit practical.
