What causes the green staining on my walls?

That's usually algae, which establishes on damp, shaded render and brick. It's cosmetic rather than structural, but it does spread if left, which is why we treat the growth with biocide rather than just rinsing the surface.

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.

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.

A soft-washed render or brick elevation in Walker comes back looking close to its original colour — not patchy, not streaked, and not stripped back to bare aggregate the way an aggressive pressure wash can leave sand-and-cement render.

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

Render and brick cleaning for homeowners

Green streaks down the render or a brick wall gone dull and dark aren't just cosmetic — they're a sign of active algae and lichen growth that keeps spreading if it's left. A soft wash treatment deals with it properly: biocide kills the growth, a gentle rinse clears it away, and Walker homes look cared for again without any risk to the render coat itself.

Trained in the method that actually matters

Biocide trained (2024): The core skill behind a proper soft wash — knowing what to apply and for how long.
Never pressure washing render: Soft wash and steam only on render and brick, every time.
Fully insured: Covered for peace of mind on every job we do.

The biocide and methods behind a proper render clean

The core of a proper render clean is the biocide treatment — a professional-grade solution applied to kill algae, lichen and the black fungal growth that causes streaking, rather than just washing the surface growth away.

We're biocide trained (2024), so application rates and dwell times are matched to the render type and how bad the growth actually is, not a standard spray-and-rinse. Steam is used where black staining on brick needs extra lift, and low-pressure rinsing finishes both render and brick without disturbing the surface underneath.

Render & Brick Cleaning (Soft Wash) in Walker — common questions

We soft wash render and clean brick across Walker, using biocide treatment and low pressure to lift algae, lichen and black streaking without risking the render coat or old mortar. Fully insured and biocide trained (2024) — get in touch for a quote.
