Render Cleaning Service in Hull & East Yorkshire

Render cleaning removes algae, green staining, black mould, and pollution from modern acrylic and silicone renders using low-pressure soft washing. This method restores appearance safely without damaging delicate finishes like K Rend, Weber, or Monocouche. For most homes in Hull and East Yorkshire, results last 3–5 years when treated correctly.


Render homes look great when new — but our damp coastal climate makes it a magnet for algae, green film, black streaks and pollution. Pressure washing can damage textured renders, so professional soft washing is the safest way to clean, protect, and prolong their life. A proper render clean isn’t just cosmetic — it prevents long-term staining, patchiness, and costly repainting.

We carry out a full inspection prior to cleaning your render.

How Our Render Cleaning Process Works (step-by-step)

Site Inspection & Render Identification

We assess your render type, condition, and problem areas.

Diagnosis of Staining

We identify whether it’s algae, lichen, pollution, or mould — so we choose the right treatment to clean your render.

Surface Preparation

Before cleaning your render we protect plants, and surrounding surfaces where needed.

Low-Pressure Soft Wash Treatment

A specialist cleaning solution is applied evenly at low pressure and scrubbed into the render.

Dwell Time (the science bit)

The solution breaks down organic growth without harming the render.

Controlled Rinse

We rinse gently to remove dead contamination and if required re-treat until your render is clean.

Why Render Gets Dirty in Hull & East Yorkshire

Homes across Hull, and the Holderness coast sit in a humid, sheltered environment that encourages organic growth on textured render.


Common issues we see with Render:

  • Green algae film on north-facing walls
  • Black lichen streaks beneath gutters
  • Yellow staining from pollen and pollution
  • Dark patching around windows and vents
  • Staining behind downpipes and drain outlets


Modern acrylic renders are breathable and textured — which is great for your home, but also creates tiny pores where algae can take hold.

What is a Professional Render Cleaning Service?

Professional render cleaning is a gentle, low-pressure soft wash treatment designed specifically for delicate external wall systems.


We clean all types of render :

âś… Rend Weber render âś…Monocouche âś…Silicone render âś…Acrylic render âś…Painted render âś… Textured finishes


Unlike pressure washing, soft washing cleans biologically — killing algae at the root rather than blasting the surface.

If you’re unsure — just ask. We likely cover your area.

  • Will render cleaning damage my walls?

    No — we use low-pressure soft washing specifically designed for render.

  • How long do results last?

    Typically 3–5 years, depending on shade, location, and exposure. We recommend a top up spray treatment every two years to keep your render clean.

  • Can you clean K Rend?

    Yes — safely. We clean K Rend, Weber, Monocouche, and painted render.

  • Is pressure washing used?

    No. We avoid pressure washing on render because it can cause long-term damage.

  • Will the stains come back?

    They can over time, but professional treatment significantly slows regrowth. And a top up treatment is recommended every two years to optimise the active ingredients 

  • Does render cleaning make a mess?

    We work carefully and protect your property where needed.

  • How long does the job take?

    Most homes take  a full day to clean, but can take longer if additional treatments are required.

  • Do I need to repaint after cleaning?

    Usually no — most renders look dramatically improved without painting. It is not advisable to paint most modern renders as they are designed to be breathable.

  • What areas do you cover?

    We cover Hull and the wider East Yorkshire area, including surrounding towns and villages.

If your render is looking tired, green, or stained, we can help.
