Render Cleaning — Warranty-Safe

Ireland's most trusted render cleaning specialists

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.

Why render gets dirty

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:

• Algae — red and green streaks that spread across the facade over time
• Moss and lichen — can grip into the render surface if left untreated
• Pollution and atmospheric dirt — grey-black deposits around soffits, window reveals and areas sheltered from rain

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.

Why pressure washing damages render

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.

Our AlgoClear softwash process

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:

• AlgoClear solution is applied gently across the facade at low pressure — no surface damage, no forced water ingress
• The active ingredients penetrate organic growth, killing algae, moss and lichen at the root
• The treatment keeps working after we leave — growth continues to die back and fade over the weeks following treatment
• A final low-pressure rinse removes residue and leaves the facade clean and protected

The result is a thoroughly cleaned render that looks as it should — and a warranty that remains intact.

Residential & commercial facades

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.

Other exterior cleaning

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.
