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.

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.

Is soft washing safe for older brick and lime mortar?

Yes — low pressure and steam are both gentler on lime mortar than a pressure washer would be, which matters on older brickwork where the pointing is softer than modern cement-based mortar.

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.

Steam cleaning for brick and stubborn staining

Steam is used where black streaking or ingrained staining on brick needs extra lift beyond what biocide alone will shift. It works at high temperature rather than high pressure, which suits older brick and mortar that wouldn't take forceful water well.

Homes & businesses

Industrial and warehouse unit cleaning

Units around Belmont Industrial Estate often have large expanses of render or block that pick up algae staining fast, especially on shaded or north-facing walls. We soft wash at scale, with spill management training covering biocide use around industrial sites and shared yards.

Render and brick on Victorian terraces

Historic city centre little changed in 200 years, with Georgian buildings. means a fair few properties in Durham still have original lime-mortared brickwork, sometimes with rendered sections added later — and it's the lime mortar that needs the most care, since it's softer than modern cement pointing and won't take pressure washing without eroding.

Black streaking on brick chimneys and sooted-looking render on old repairs are both common on streets like this, and both respond well to a soft wash and biocide treatment without touching the mortar joints.
