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.

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.

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.

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.

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.

Render & Brick Cleaning (Soft Wash) in Houghton-le-Spring — algae staining lifted off the wall, in the City of Sunderland area

If render or brickwork in Houghton-le-Spring has gone green, black-streaked or lichen-covered, we'll soft wash it back to a clean, even finish — no pressure washer near the render coat, ever.

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.

Why local coverage matters for render cleaning

Knowing the area helps with more than just travel time — we've seen the render types, growth patterns and exposure common to Houghton-le-Spring and the places around it, like Hetton-le-Hole and Shiney Row, which means fewer surprises once we're on site.

Homeowners

Protecting new-build render finishes

If your home has monocouche or K-rend and it's only a few years old, the last thing you want near it is a pressure washer — it's thin enough that aggressive cleaning can strip or crack the coloured finish. Soft washing keeps the render looking new for longer, without the risk.

Getting to you

We're based in Washington and cover roughly 45 miles out from there, so Houghton-le-Spring is well within reach — A690 makes it a straightforward run for us with equipment, which keeps travel time, and cost, down.

Typical render and brick cleaning prices

Prices depend on render type, how established the growth is, property size and access, so these are typical ranges rather than fixed prices — we'll always confirm a firm figure after seeing photos or visiting.

Single elevation (render or brick)	from around £150–£220
Semi-detached property, all elevations	typically £280–£380
Detached property, all elevations	typically £400–£650
Bungalow, all elevations	typically £220–£320

How the process differs by surface

1
Render assessment
K-rend, monocouche, pebbledash and sand-and-cement each get treated slightly differently based on thickness and texture.
2
Brick and mortar check
Pointing condition is noted, especially on older lime-mortared brick, so pressure stays low enough not to erode it.
3
Biocide on render
Render gets a biocide soft wash with dwell time suited to how established the algae or lichen is.
4
Steam on brick
Brickwork with black streaking or ingrained staining often gets steam treatment for extra lift.
5
Rinse and inspect
Both surfaces are rinsed at low pressure and checked together before we finish up.

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.
