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.

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.

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.

That's the difference soft washing makes. Biocide does the work of killing algae, lichen and black fungal growth, and a gentle low-pressure rinse finishes the job without disturbing the render coat or the brick pointing underneath it.

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

Algae and black streaking on render and brick tend to show up worst through autumn and winter, when Newcastle upon Tyne gets longer damp spells and less direct sun to dry walls out between showers. By spring the growth has often had months to get properly established.

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.

Pebbledash and render on 1960s–70s estates

Neoclassical 'Tyneside Classical' centre on a medieval street layout; 20th-century Byker Wall estate is Grade II* listed. is typical of what we see on estates from this era — mostly pebbledash or sand-and-cement render, and after fifty-plus years it's often had patch repairs that show up differently once algae and lichen are cleaned off, which is normal and not something we've caused.

These older render systems can actually take a soft wash well, being thicker than modern monocouche, but pressure washing will still dislodge loose pebbledash aggregate that's been slowly working free for decades.

Access for commercial and multi-site jobs

For larger or commercial properties near A1, we plan access and parking in advance so equipment can be set up without disrupting deliveries, customers or shared yards.

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

How we clean render and brick, step by step

We start with a walk-round survey of the render or brick, checking render type, how established the algae or lichen growth is, and whether there's any cracking or damage worth noting before we start.

Biocide is applied first and left to dwell, breaking down algae, lichen and black streaking at the root rather than just knocking it off the surface. Once it's worked, we rinse at low pressure — or with steam on brick and stubborn black staining — lifting the dead growth away without forcing water behind the render or into old mortar joints.

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.
