How long does render cleaning take?

Most single properties take a few hours to a day, depending on size, growth level and access. Larger or commercial elevations can take longer — we'll give you a time estimate with your quote.

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.

Is the black streaking on my brick chimney a problem?

Black streaking is typically fungal growth rather than damage to the brick itself, though it can look worse the longer it's left. Soft washing and steam lift it without harming the brick or mortar underneath.

My render has cracks — can you still clean it?

We'll look at the cracking before we start. Minor hairline cracks aren't usually a problem for a soft wash, but we'll flag anything that looks like it needs attention beyond cleaning rather than working over it.

Can render cleaning be done in winter?

Yes, as long as it's above freezing and dry enough on the day — biocide needs to dwell on the surface rather than be washed off by rain straight after application.

If render or brickwork in Byker has gone green, black-streaked or lichen-covered, we'll soft wash it back to a clean, even finish — no pressure washer near the render coat, ever.

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.

Algae and black streaking on render and brick tend to show up worst through autumn and winter, when Byker 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.

Working safely on render and brick elevations

We're fully insured and asbestos awareness trained, which matters on older render and brickwork where past repairs or outbuildings can involve materials that need identifying before any work starts.

Biocide use is covered by our spill management training, so chemicals are applied, contained and disposed of properly rather than left to run off into drains or planting. Windows, doors, cars and gardens get protected before we start, and higher elevations are worked from a safe platform rather than putting pressure equipment where it shouldn't be.

Protecting the value of your home

Left untreated, algae and lichen on render don't just look bad — trapped moisture behind established growth can eventually affect the render coat itself, and black streaking on brick can mask early signs of pointing that needs attention. Regular soft washing keeps growth from reaching that point, which is cheaper than dealing with render or repointing repairs later.

Cleaning modern monocouche and K-rend

Includes the Byker Wall estate, Grade II* listed and on UNESCO's list of outstanding 20th-century buildings. on newer estates around Byker is almost always finished in monocouche or K-rend — thin, factory-coloured renders that look sharp when new but show algae staining fast, especially on north-facing elevations that don't get much direct sun.

These systems are also the most vulnerable to pressure damage. The coloured layer is only a few millimetres thick, so soft washing with biocide is the only method that cleans the growth without risking the finish itself.
