Professional Render Cleaning in Coventry

Black streaks and green algae on rendered walls are one of the most common complaints we hear from homeowners across Coventry. Rendered properties — particularly those with K-rend, monocouche or pebbledash finishes — are highly susceptible to organic growth, especially in the UK's damp climate. Once algae takes hold, it spreads quickly and can make even a modern property look years older.

Our render cleaning service in Coventry uses a specialist soft wash process that lifts and removes algae, moss, lichen and black streaks without damaging the render surface. High-pressure washing can cause serious damage to rendered walls — cracking older sand and cement render, stripping the surface layer of K-rend, and forcing water into the wall behind. Our low-pressure technique is safe, effective, and the results speak for themselves.

We've cleaned hundreds of rendered properties across Coventry, Kenilworth, Bedworth, Nuneaton, Warwick and Leamington Spa. Whether your render has a light covering of algae or years of heavy growth and staining, we'll restore it to a clean, fresh appearance and treat it to stay cleaner for longer.

Why Soft Wash for Render?

Rendered surfaces are much more delicate than they appear. High-pressure washing can strip the surface layer of K-rend and monocouche, cause cracking in older sand and cement render, and force water into the wall behind — leading to damp problems. Our soft wash method uses biodegradable cleaning solutions at low pressure to safely remove organic growth without any of these risks.

After cleaning, the render is treated with a biocide that kills any remaining growth at the root, helping to keep it cleaner for longer. We can also apply a protective treatment to inhibit future algae and moss growth — ask us about this when you call for a quote.
