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.

How often does render need cleaning?

It depends on aspect and exposure — shaded, north-facing or coastal-exposed elevations tend to need attention more often than sheltered, south-facing ones. Most properties do well with a clean every couple of years, sometimes longer.

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.

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.

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.

Do you clean commercial and industrial premises?

Yes, we clean render, brick and block on shops, offices and industrial units, usually scheduling around opening hours so it doesn't disrupt business.

Render cleaning only works long-term if the method matches the surface, so on K-rend, monocouche, pebbledash and sand-and-cement render in Bishop Auckland we soft wash — biocide applied at low pressure, given time to work into the growth, then rinsed off gently.

If render or brickwork in Bishop Auckland 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.

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.

Soft washing vs pressure washing: why it matters

Pressure washing forces water directly at the render surface, and on K-rend, monocouche and pebbledash that can crack the coating, blow sections off the wall entirely, or strip the texture back to bare aggregate.

Soft washing does the opposite. Biocide does the actual cleaning work, and the rinse afterwards is at low pressure — just enough to carry the dead algae and lichen away without stressing the render or the brick pointing underneath. The result looks the same on the day either way, but only one of those methods leaves the coating intact a year later.

Our standard render and brick cleaning process

1
Survey
We check the render type, growth level and any existing cracking or damage before quoting.
2
Protection
Windows, doors, plants and any nearby vehicles are covered or moved clear.
3
Biocide application
Biocide is applied to kill algae, lichen and black fungal growth at the surface.
4
Dwell time
The treatment is left to work into the growth — rushing this step is where poor results come from.
5
Low-pressure rinse
Dead growth is rinsed away at low pressure, never with a pressure washer on render.
6
Final check
We walk the elevations with you, or send photos, to confirm the finish before we leave.

What affects the price

Two similarly sized properties can price differently depending on render type — monocouche and K-rend usually cost a little more to treat properly than sand-and-cement, since they need more careful handling — and on how much scaffolding or platform access is needed for higher elevations.

Terraced house, front elevation	from around £120–£180
Estate house, all elevations	typically £250–£350
Large detached / high elevations	typically £500–£750
Commercial unit (per elevation)	POA depending on scale
