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.

How long does render cleaning take?

Most single properties take a few hours to a day, depending on size, growth level and access. Larger or commercial elevations can take longer — we'll give you a time estimate with your quote.

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.

How much does render cleaning cost?

It varies with render type, property size, growth level and access, but typically runs from around £150 for a single elevation up to £650 or more for a full detached property. We'll confirm an exact figure with a quote.

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.

Housing across Durham County Council covers everything from 1930s pebbledash semis to newer K-rend and monocouche estates, and render cleaning has to be matched to what's actually on the wall — a method that's fine on sand-and-cement render can strip a thin acrylic monocouche coat if it's done with a pressure washer instead of a soft wash.

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.

We soft wash render and use steam or gentle low-pressure methods on brick, adjusting biocide dwell time and rinse pressure to what the surface can actually take.

Render and brick cleaning costs, including common extras

Our quotes are always based on what we actually find on site, not a generic price list — established lichen, difficult access or a full portfolio of buildings all shift the number, so treat the ranges below as a starting point.

Standard soft wash, single storey	typically £180–£280
Two-storey property, all sides	typically £350–£550
Additional steam treatment (heavy staining)	add around £60–£120
Gable end / hard-to-reach elevation	add around £40–£90

Access for commercial and multi-site jobs

For larger or commercial properties near A689, we plan access and parking in advance so equipment can be set up without disrupting deliveries, customers or shared yards.

Shaded render and brick under trees

Render and brick under tree cover or on permanently shaded elevations in Sedgefield stay damp longer after rain, and that's exactly the condition lichen and green algae need to take hold — these walls are often the worst-affected on a property even when the rest of the house looks fine.

We give shaded elevations a longer biocide dwell time where the growth is established, since a quick treatment on heavily lichen-crusted render or brick rarely shifts it in one pass.

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.

Rinse water and runoff

Rinsing is done at controlled low pressure, which means less runoff overall than a pressure wash produces, and what does run off is mostly water rather than a heavy chemical load, since the biocide has already done its job by the time we rinse.
