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.

Do you clean brickwork as well as render?

Yes, we clean brick alongside render using soft washing and steam, particularly for black streaking and ingrained staining, and we adjust pressure to protect older lime mortar.

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.

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.

Newton Aycliffe Render Cleaning Specialists

Render and brick cleaning for homes and businesses in Newton Aycliffe. Biocide soft washing and steam methods, fully insured, with before-and-after photos.

A soft wash treatment breaks that cycle rather than just resetting it. Biocide gets down into the render texture and brick pores, so regrowth is slower and the wall stays cleaner for longer than a one-off rinse would manage.

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.

If render or brickwork in Newton Aycliffe 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.

Access on site

Most render and brick cleaning jobs just need reasonable access to an outside tap or our own water supply, and enough room to set up equipment near the elevation being cleaned — tight side passages or gated access are worth mentioning when you book so we can plan for it.

How we clean render and brick, step by step

We start with a walk-round survey of the render or brick, checking render type, how established the algae or lichen growth is, and whether there's any cracking or damage worth noting before we start.

Biocide is applied first and left to dwell, breaking down algae, lichen and black streaking at the root rather than just knocking it off the surface. Once it's worked, we rinse at low pressure — or with steam on brick and stubborn black staining — lifting the dead growth away without forcing water behind the render or into old mortar joints.

Soft washing equipment

Our soft wash setup delivers biocide and rinse water at low pressure through a controlled system, rather than the high-force jets a pressure washer produces. That's the difference between cleaning render safely and risking cracked or blown coatings.

Render and brick near former colliery terraces

Post-war new town estates. in and around Newton Aycliffe often means solid brick with minimal cavity, built for mining communities, and decades of coal dust and industrial residue can leave a grey-black bloom on the brick that looks like dirt but is partly ingrained soot.

Steam and biocide soft washing lift this kind of ingrained staining better than a straightforward rinse would, working into the brick surface rather than just moving surface dirt around.
