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.

Will the biocide harm my plants or pets?

We cover or move planting before we start and are spill management trained to handle and dispose of chemicals properly, minimising any risk to plants, pets or the surrounding area.

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.

Green algae streaking down a render elevation, black fungal spotting creeping across pebbledash, lichen crusting onto exposed brick — render and brickwork in Hartlepool take a battering from damp, shade and salt-laden air, and pressure washing, the instinct of most contractors, cracks and blows render coats that were never built to take it.

Why does render in Hartlepool 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.

Nearby places we also cover

Homeowners

Getting a property ready to sell or let

Render that's gone green or brick that's streaked black is one of the first things a buyer or tenant notices from the kerb, before they've even seen inside. A soft wash clean is one of the more cost-effective things you can do before photos or viewings — it lifts the whole look of the property for a fraction of what a repaint or re-render would cost.

Protecting what's around the property

Before any biocide goes on, we cover or move planting, garden furniture and anything nearby that shouldn't come into contact with it. We're spill management trained, so runoff and unused product are handled and disposed of properly, not left to find their way into drains or beds.

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.

Reaching rural and outlying properties

Properties a little further out from Hartlepool 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.
