“Softwashed our K-Rend and treated the roof. Came back six months later to check the biocide had done its work — no one does that. House looks brand new.”

- 02
Softwash
Biocide applied at the correct concentration, left to dwell, then rinsed gently.
- 03
6-month return
We come back six months later to re-treat at no extra cost — if required.
- 04
Annual maintenance
Optional yearly softwash keeps the finish looking new indefinitely.
The difference
What a proper softwash does to a green render.
Render doesn't go green overnight. Algae and lichen take hold wherever the wall stays damp — under the sills, along the downpipe, on the shaded aspect — and creep outwards until the whole elevation reads grey rather than white.
Biocide softwash kills it at the spore level instead of blasting it off, so the surface of the render is left intact and the finish comes back even rather than patchy. Drag the slider to see the same elevation before and after.
- Biocide softwash and low-pressure rinse — no jetting
- K-Rend, ProRend, silicone and monocouche safe
- Planting dampened and sheeted before we start
FAQ
Common questions about render.
Can't see yours? Call 01647 279 079 — happy to chat it through.
Why softwash and not jetting?
Pressure jetting strips the top layer of render, removes the colour, and accelerates recontamination. Biocide softwash kills the algae/lichen at the spore level and leaves the substrate intact.
Is it safe on K-Rend, ProRend and silicone render?
Yes — softwash is the manufacturer-recommended cleaning method for these finishes. We never jet K-Rend, ProRend or silicone.
How long does the result last?
Typically 3–5 years between cleans on a sheltered elevation, 2–3 years in damp/shaded aspects. The 6-month biocide top-up (if required) significantly extends this.
Do you protect plants and garden?
Yes — all planting is dampened and sheeted before application. Biocide is diluted below levels harmful to surrounding vegetation.

“Took on our roof and gutter clean — drone survey first, biocide on the moss, gutters vacuumed from the ground. Slick, tidy, no ladders against the fascia.”
