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.

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.

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.

Soft washing is the correct method: biocide does the cleaning, low pressure just rinses it away, and the render coat itself is never put under the kind of force a pressure washer generates.

Why does render in Bishop Auckland turn green on one elevation and stay clean on the other three? Usually it comes down to shade, prevailing wind and how much rain that particular wall sees — north and west-facing K-rend and monocouche hold moisture longer, and moisture is exactly what algae and lichen need to get established.

Brickwork gets the same care. Steam or soft washing lifts black streaking and algae without eroding old lime mortar joints, which is where a pressure washer does most of its damage on older brick properties.

Rinse water and runoff

Rinsing is done at controlled low pressure, which means less runoff overall than a pressure wash produces, and what does run off is mostly water rather than a heavy chemical load, since the biocide has already done its job by the time we rinse.

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.
