Will pressure washing damage my render?

Yes, in most cases. Pressure washing can crack render, blow sections off K-rend and monocouche, and strip texture from sand-and-cement. We only soft wash render, using biocide and low pressure instead.

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.

What causes the green staining on my walls?

That's usually algae, which establishes on damp, shaded render and brick. It's cosmetic rather than structural, but it does spread if left, which is why we treat the growth with biocide rather than just rinsing the surface.

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.

Why has the render on one side of my house gone green and not the others?

Shade and moisture are usually the reason — north or west-facing walls that stay damp longer after rain are more likely to develop algae and lichen than sunnier elevations.

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.

We use soft washing and steam methods instead. A biocide treatment kills the growth at the root, a low-pressure rinse lifts dirt without forcing water behind the render, and the result actually lasts because the problem is gone, not just blasted off the surface for a few months.

Render and brick cleaning for homeowners

Green streaks down the render or a brick wall gone dull and dark aren't just cosmetic — they're a sign of active algae and lichen growth that keeps spreading if it's left. A soft wash treatment deals with it properly: biocide kills the growth, a gentle rinse clears it away, and Crook homes look cared for again without any risk to the render coat itself.

Render cleaning on exposed, high-ground properties

Properties on higher or more exposed ground around Crook take more wind-driven rain, and that constant wetting pushes render and brick towards black streaking and algae faster than a sheltered property nearby.

Exposure also means growth can come back quicker after cleaning, so we're upfront about that rather than overselling a one-off clean as a permanent fix — biocide treatment slows regrowth, it doesn't stop weather doing what weather does.

What a finished render or brick clean looks like

A finished job means green and red algae gone, black streaking lifted, lichen removed, and the render or brick colour back close to what it was when the wall was first finished.

Because the biocide has actually killed the growth rather than just removed it visually, regrowth is slower than it would be after a quick pressure rinse. We take before-and-after photos of every job, so you can see exactly what changed.

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.

While Crook is one of the areas we work in regularly, we cover a wide spread around it, from Esh Winning, Bishop Auckland, Brandon and Spennymoor outward — one contractor for render and brick cleaning across the whole area, rather than a patchwork of local one-off jobs.
