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.

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.

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.

What's involved in cleaning lichen off render?

Lichen is one of the more stubborn growths — it often needs a longer biocide dwell time than algae to break down properly. We treat it accordingly rather than rushing the rinse.

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.

Why does render in Spennymoor 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.

Soft washing costs a little more than a quick pressure rinse would, but it doesn't carry the risk of blown render or damaged pointing — repairs that cost far more than the cleaning itself would have.

Brickwork gets the same care. Steam or soft washing lifts black streaking and algae without eroding old lime mortar joints, which is where a pressure washer does most of its damage on older brick properties.

Homeowners

Protecting the value of your home

Left untreated, algae and lichen on render don't just look bad — trapped moisture behind established growth can eventually affect the render coat itself, and black streaking on brick can mask early signs of pointing that needs attention. Regular soft washing keeps growth from reaching that point, which is cheaper than dealing with render or repointing repairs later.

Getting to you

We're based in Washington and cover roughly 45 miles out from there, so Spennymoor is well within reach — A688 makes it a straightforward run for us with equipment, which keeps travel time, and cost, down.

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 handle established or difficult growth

1
Identify the growth type
Red algae, green algae, black streaking and lichen all respond slightly differently to biocide treatment.
2
Test area
On heavily established growth we'll often treat a small area first to confirm how the render responds.
3
Extended dwell time
Stubborn lichen crusting gets longer biocide contact time rather than a stronger rinse.
4
Targeted steam
Any remaining black staining on brick after biocide treatment gets a steam pass to finish it off.
5
Rinse and review
A final low-pressure rinse and a walk-round to check nothing's been missed before we leave.
