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.

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.

Do you offer a free quote?

Yes — send a few photos or ask for a site visit and we'll give you a proper quote based on render type, size and access, with no obligation.

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.

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.

Do you clean commercial and industrial premises?

Yes, we clean render, brick and block on shops, offices and industrial units, usually scheduling around opening hours so it doesn't disrupt business.

Whether it's a rendered new-build estate, a pebbledash semi from the 1960s–70s, or an older brick terrace with lime mortar, properties in Morpeth each need a slightly different approach — modern monocouche is thin and can be damaged by pressure, while old lime-pointed brick needs low pressure for a different reason: the mortar itself is soft.

A lot of people assume render cleaning means pressure washing, the same as a patio or driveway. It doesn't, and treating render like a hard surface is how cracking, staining and blown coatings happen, especially on thin monocouche and K-rend systems.

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.

What we do — and never do — on render

We do: soft wash with biocide, use steam or low pressure on brickwork, protect windows, doors and planting before we start, and match dwell time to how established the growth is.

We don't: use a pressure washer directly on render, rush the biocide dwell time, or treat old lime-pointed brick the same way as modern cement pointing — the mortar itself needs a gentler approach. That distinction is what keeps render cleaning from turning into a render repair job.

The biocide we use

We use professional-grade biocide formulated to kill algae, lichen and fungal growth on render and masonry, applied at rates matched to the surface and how established the growth is. We're biocide trained (2024), so it's used correctly rather than sprayed on and rinsed off too soon.

Homeowners

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.

Reaching rural and outlying properties

Properties a little further out from Morpeth are no problem — we cover the wider area and bring everything we need with us, so an outlying farmhouse or converted barn gets the same soft wash treatment as a property in the town centre.

We're not just a Morpeth company

While Morpeth is one of the areas we work in regularly, we cover a wide spread around it, from Ashington, Cramlington, Blyth and Ponteland outward — one contractor for render and brick cleaning across the whole area, rather than a patchwork of local one-off jobs.
