Professional Render Cleaning Service
Render can completely change the appearance of a property, but once algae, weather staining and organic growth begin to develop, a clean rendered finish can quickly start to look tired and neglected.
Bring Tired, Stained Render Back to Life
This is particularly noticeable on lighter coloured render, where green growth, red staining and darker patches can stand out across large areas of the building.
Professional render cleaning isn't about applying as much pressure as possible. We first look at the type and condition of the render, identify what is causing the discolouration and choose a cleaning approach appropriate for the surface.
The aim is simple:
remove the contamination, improve the appearance of the property and do it without unnecessarily stressing the render beneath it.
Why Does Render Become Stained?
The staining seen on rendered properties isn't always ordinary dirt.
Exterior walls are continually exposed to moisture, shade, airborne contamination and organic spores. Once conditions are favourable, algae and other biological growth can establish themselves across the surface.
North-facing elevations, sheltered walls and areas that remain damp for longer are often particularly suseptable.
Green Algae Staining
Green films and patches commonly develop where rendered walls remain damp or receive limited sunlight.
Red Algae Staining
Red or pink staining can develop across rendered elevations and can become particularly noticeable on pale finishes.
Lichen & Organic Growth
More established biological growth can become attached to the surface and may require additional treatment.
Weather & Airborne Soiling
Rainwater, pollution and general environmental contamination can leave render looking patchy or dull.
Render Needs a Different Approach
A pressure washer is an excellent tool when it's being used on an appropriate surface. Render, however, requires a much more considered approach.
Using excessive pressure can potentially mark or damage some rendered finishes and, more importantly, pressure alone doesn't necessarily address the biological growth responsible for the staining.
That's why our render cleaning service focuses on treating the contamination rather than simply trying to blast it away.
A suitable cleaning treatment is applied in a controlled manner and given time to work before the surface is gently rinsed or finished according to the type and condition of the render.
“The aim isn't to see how much pressure we can use. It's to achieve the best result using the most appropriate method for the surface.”

Cleaning Different Types of Render
Different render systems can have different finishes, textures and maintenance requirements. Before cleaning, we inspect the surface and its condition so the treatment can be adjusted accordingly.
K REND & SILICONE RENDER
Modern rendered finishes can look fantastic but biological staining can become particularly noticeable on light colours. We use controlled cleaning methods rather than treating every surface the same.
MONOCOUCHE RENDER
The condition of the surface is assessed before treatment, with particular attention paid to existing cracking, deterioration or previous repairs.
ACRYLIC & TEXTURED
Textured surfaces can hold contamination within their finish. Treatment is selected according to the surface and level of organic growth present.
PAINTED & TRADITIONAL
Older or previously painted render needs careful assessment before cleaning. Where we identify deterioration or a surface we don't believe should be cleaned, we'll tell you.
Our Render Cleaning Process
1 — INSPECT
We assess the type, condition and accessibility of the rendered surfaces before work begins.
4 — TREAT
Cleaning solution is applied carefully and evenly across the affected render.
2 — IDENTIFY
We look at the staining and contamination present so we can select an appropriate treatment.
5 — DWELL
The treatment is given time to work on the organic contamination rather than simply being washed straight off.
3 — PROTECT
Plants, windows and surrounding surfaces are considered and protected where necessary.
6 — FINISH
The surface is gently rinsed or finished as appropriate, with additional treatment applied where required.
Render Cleaning Before & After
What Happens After Your Render Has Been Cleaned?
Cleaning removes the existing contamination, but exterior walls will naturally continue to be exposed to moisture, weather and airborne organic spores that cause algae.
How quickly staining eventually returns depends on the property itself. Shade, nearby trees, orientation, exposure and how long the surface remains damp can all make a difference.
Rather than waiting until the render becomes heavily contaminated again, periodic maintenance treatment can help manage regrowth and keep the property looking cleaner for longer.
We'll give you straightforward advice based on your particular property rather than promising an unrealistic fixed lifespan for every clean.

Render Cleaning FAQs
Can you pressure wash render?
We generally avoid aggressive pressure washing on rendered surfaces. Our approach is based around treating the contamination and using controlled cleaning methods appropriate to the surface.
Can you clean K Rend?
Yes. We clean K Rend and other modern rendered finishes, subject to an inspection of their condition before treatment.
What causes green staining on render?
Green staining is commonly associated with algae and other organic growth. Damp, shaded elevations are often affected more quickly than walls receiving plenty of sunlight.
What causes red or pink stains on render?
Certain forms of biological growth can create distinctive red or pink staining across rendered surfaces, particularly on pale finishes.
Will render cleaning damage my walls?
The purpose of inspecting the render first is to select an appropriate cleaning method. We avoid unnecessarily aggressive cleaning and take existing defects or deterioration into account before starting.
How long will my render stay clean?
There isn't one answer for every property. Orientation, shade, nearby vegetation, weather exposure and moisture all affect how quickly organic growth can return.
Can render be treated again before it becomes heavily stained?
Yes. Periodic maintenance treatment can be a sensible way of managing regrowth before the render becomes heavily contaminated again.
How long does render cleaning take?
Many residential jobs can be completed within a day, although larger properties, difficult access or heavier contamination may require longer. We'll discuss this during your quotation.
Do I need to repaint my render after cleaning?
Not necessarily. Where the discolouration is being caused primarily by surface contamination, cleaning can significantly improve its appearance without repainting. Existing paint failure, damage or permanent staining may require separate attention.
How much does render cleaning cost?
The cost depends on the size of the property, access, condition of the render and the treatment required. We provide a clear quotation after assessing the work.
Is Your Render Looking Green, Red or Tired?
If staining and organic growth are spoiling the appearance of your property, we'll take a look and explain the most appropriate way to deal with it.
