Do you do roofs as well as render?

Yes. Many Greenwich homeowners book both at once. We treat concrete and clay tile roofs with the same soft wash biocide to remove moss and black streaks.

Why has my render gone red or pink?

Red staining is typically a specific algae that thrives on silicone K-Rend, particularly in Greenwich where urban pollution and pollen-heavy summers accelerate growth. It responds well to specialist biocide treatment.

Is the soft wash treatment safe for plants?

We sheet down sensitive borders and rinse any overspray. The biocide breaks down quickly in soil and is widely used around residential gardens across Greenwich.

Can you clean painted render?

Yes — painted render in Greenwich responds very well to soft wash. The treatment lifts grime and algae without stripping the paint, unlike high-pressure washing.
