Facade cleaning with K-Rend-recommended products — your render warranty stays intact.
We specialise in K-Rend render and facade cleaning. We clean with AlgoClear — the product approach K-Rend themselves recommend — applied the correct way, so our process will not invalidate your K-Rend warranty.
Modern textured renders like K-Rend are designed to be durable and attractive, but Ireland's damp climate makes them a target for organic growth. The most common problems are:
Left untreated, these growths can worsen and become harder to remove. More importantly, using the wrong cleaning method — particularly high-pressure washing — can permanently damage the render texture, strip the surface layer, and void your manufacturer warranty.
High-pressure washing forces water into the render at a level it was never designed to absorb. This can cause surface erosion, open up hairline cracks, and drive moisture into the substrate behind the render — leading to damp problems that are far more expensive to fix than a dirty facade. K-Rend specifically advise against pressure washing for this reason.
We clean render using AlgoClear applied at low pressure — a professional biocidal wash that is safe for rendered surfaces and fully approved for use on K-Rend. The process works like this:
The result is a thoroughly cleaned render that looks as it should — and a warranty that remains intact.
We work on private homes, apartment blocks, commercial buildings and any facade where render care matters. If you're unsure whether your render type is suitable, call us and we'll advise.
Render cleaning is part of our broader softwash services — the same low-pressure, chemistry-led approach works on roofs, painted exteriors, natural stone, boundary walls and more.
