Render Cleaning, with the kind of finish that feels cared for

Green algae, black mould, and red staining make rendered walls look years older than they are. Our soft wash method kills biological growth at the root with low-pressure cleaning and biodegradable agents, no risk of cracking, no water forced behind your render.

Somerset's wet climate is perfect for algae, moss, and black mould. Within a few years, even new render can look green, stained, and tired. Pressure washing seems like the obvious fix, but high-pressure jets crack render, blow out pointing, and force water into wall cavities. Our soft wash method is the professional alternative: biodegradable cleaning agents break down biological growth, then a low-pressure rinse removes everything safely. We cover K-rend, monocouche, silicone, acrylic, cement, and lime render. An optional biocide treatment after cleaning slows regrowth for 2-3 years.

Why homeowners choose us

The case for our render cleaning

Low-Pressure Soft Wash, No Damage

High-pressure jets crack render and force water behind walls. Our soft wash uses low pressure with biodegradable cleaning agents instead.

Kills Algae & Moss at the Root

We do not just rinse the surface clean. Our biocide treatment kills biological growth so it takes years to return, not months.

All Render Types Covered

K-rend, monocouche, silicone, acrylic, cement, and lime render. We match the cleaning method to your specific render system.

Transform Your Property's Appearance

Stained, green walls make a property look neglected. A soft wash restores the original clean finish and dramatically improves kerb appeal.

Optional Biocide Protection

After cleaning, we can apply a biocide treatment that inhibits regrowth for 2-3 years. Ask about this when you request your quote.

Site Visit Assessment

Every render job starts with a site visit. We assess the render type, staining severity, and access before quoting a fixed price.

Our promise

Surface-Safe Cleaning Guaranteed.

Render Cleaning questions

What is the difference between soft washing and pressure washing render?

Soft washing uses low-pressure water with biodegradable agents that kill algae at the root. Pressure washing can crack render and force water behind it. We always soft wash rendered walls.

What types of render can you clean?

K-rend, monocouche, silicone, acrylic, cement, and lime render. Each needs a slightly different approach to avoid damage, which is why specialist experience matters.

Why does render in Somerset get so dirty?

Damp weather, mild temperatures, and plenty of organic matter create perfect conditions for algae and lichen. North-facing walls and anything shaded by trees are particularly prone.

Will soft washing damage my render?

No. Low-pressure cleaning is specifically designed for rendered surfaces. We never use high-pressure jets, which can crack, pit, or force water behind the render.

How often does render need cleaning?

Every 2 to 3 years for most Somerset properties. We apply a biocide treatment after cleaning that slows regrowth and extends the time between cleans.

How long do the results last?

Typically 2 to 3 years, longer with biocide treatment. The soft wash agents continue working over the following days, killing remaining spores below the surface.
