Can you clean K-rend?

Yes. K-rend is soft washed with biocide and rinsed at low pressure — never pressure washed, since the coloured finish is thin enough to be damaged by force.

How often does render need cleaning?

It depends on aspect and exposure — shaded, north-facing or coastal-exposed elevations tend to need attention more often than sheltered, south-facing ones. Most properties do well with a clean every couple of years, sometimes longer.

What causes the green staining on my walls?

That's usually algae, which establishes on damp, shaded render and brick. It's cosmetic rather than structural, but it does spread if left, which is why we treat the growth with biocide rather than just rinsing the surface.

Do I need to be home while you work?

No, as long as we can access the areas being cleaned and there's water available. We'll leave the site tidy and can send before-and-after photos if you're not around.

What render types can you clean?

K-rend, monocouche, pebbledash and traditional sand-and-cement render — each gets treated slightly differently depending on thickness and texture, but all are soft washed rather than pressure washed.

Is soft washing safe for older brick and lime mortar?

Yes — low pressure and steam are both gentler on lime mortar than a pressure washer would be, which matters on older brickwork where the pointing is softer than modern cement-based mortar.

K-Rend, Monocouche & Brick Cleaning in Jesmond

Render gone green or brick streaked black in Jesmond? We soft wash K-rend, monocouche and pebbledash safely with biocide, never high pressure. Call Trevor for a quote.

Algae and black streaking on render and brick tend to show up worst through autumn and winter, when Jesmond gets longer damp spells and less direct sun to dry walls out between showers. By spring the growth has often had months to get properly established.

Housing across Newcastle City Council covers everything from 1930s pebbledash semis to newer K-rend and monocouche estates, and render cleaning has to be matched to what's actually on the wall — a method that's fine on sand-and-cement render can strip a thin acrylic monocouche coat if it's done with a pressure washer instead of a soft wash.

Knowing which wall is doing the damage lets us treat it properly: a biocide soft wash that gets into the texture of the render rather than just wetting the surface, followed by a low-pressure rinse that leaves the coating intact.

Render cleaning on exposed, high-ground properties

Properties on higher or more exposed ground around Jesmond take more wind-driven rain, and that constant wetting pushes render and brick towards black streaking and algae faster than a sheltered property nearby.

Exposure also means growth can come back quicker after cleaning, so we're upfront about that rather than overselling a one-off clean as a permanent fix — biocide treatment slows regrowth, it doesn't stop weather doing what weather does.

Steam cleaning for brick and stubborn staining

Steam is used where black streaking or ingrained staining on brick needs extra lift beyond what biocide alone will shift. It works at high temperature rather than high pressure, which suits older brick and mortar that wouldn't take forceful water well.
