Why Render Needs Professional Cleaning
Rendered finishes look fantastic when clean but after just a few years you can start to view discolouration and staining streaks of green, red and black. This spoils your home’s kerb appeal and you lose that new clean visual sparkle.
The green, red and black streaks and general discolouring are caused by algae and mould. Namely Trentepohlia (red algae) and Aspergillus Niger (black mould) which come to live within the render substrate. Your render discolouration is caused by these algae and mould strains living on your walls. This is referred to as biological colonisation. Consequently, you need a cleaning solution which addresses the ‘biological’ root cause.
In West Wiltshire; we have more rural settings and homes closer to fields and areas of nature. Even in towns like Melksham or Trowbridge there’s close proximity to farms and green areas meaning higher probability of biological infestation in your render. We also experience slightly wetter conditions through West Wiltshire which fuel the growth of algae and mould which live within your rendered surfaces accelerating the green, red and black streaks.
Is Pressure Washing Render a Good Idea
Pressure washing your rendered walls clean is not a good idea. Pressure washing can easily damage the surface of your render walls and leave unsightly marks where the pressure washer spray has been. The high pressure erodes the surface of your render.
Besides, pressure washing generally only cosmetically cleans the visible surface. The underlying cause of render discolouration remains and you’ll typically see a resurgence of the green, red or black streaks shortly after.
Long Lasting Render Cleaning
Softwashing – Softwasing your render is the professional, safe and long lasting way to clean your rendered walls.
Softwshing your render involves using specialised cleaning chemicals specifically formulated for cleaning exterior surfaces such as render. These specialised cleaning agents are delivered in a safe way using low pressure high reach cleaning equipment.
They kill the underlying algae and cosmetically clean your render also resulting in a full 360 degree solution that will outlast conventional cleaning methods.
How We Clean Your Render
Initial Estimate and Scope – Get started by getting in touch with us. We’ll provide you an initial estimate/ price range and outline of the scope of work. We’ll take a look at your home online and using any images you’re happy to provide.
This is ideal to provide you the ballpark price for your cleaning and highlights any particulars relating to your property and the level of cleaning required. Think of this as your initial fact finding and understanding the situation.
Site Survey and Final Quote – Once you’re happy with the Initial Estimate and Scope as above, we’ll conduct a site survey where we identify any risks or adjustments that should be taken into account for your work. It’s important that we consider the environment around your property and how this may affect your cleaning.
“Example: a home located just off a well used foot path will require cleaning with a lower concentration cleaning agent to ensure the safety of nearby pedestrians or we may need to inform a neighbour that chemical cleaning is ongoing so they can keep their cat in to avoid exposure.“
Render Cleaning – We’ll arrive and prepare your home for cleaning which involves masking relevant parts of your home in some cases such as coloured doors or fittings and creating a cordon where necessary.
We’ll then conduct the cleaning to restore the original appearance of your render and also ensure the underlying biological colonisation is killed to stop any resurgence.
Time – On average, most render cleaning tasks on homes around West Wiltshire are completed by us within 3-6 hours.
Render Cleaning Considerations for West Wiltshire
Pro-Active Cleaning
Prevent long-term damage before it sets in
Your don’t have to wait until your render looks unsightly.
Once you observe the start of biological matter and discolouration in your render you should pro-actively seek cleaning.
This is significantly cheaper because the cleaning process can be completed using lower powered cleaning products and can be completed in lesser time with lower safety implications.
If your home is just starting to show the signs of render discolouration we can stop the biological growth causing it and apply specialised products which have an ongoing cleaning effect.
From here we can offer a discounted maintenance program for your home.
Heavily Stained Render
Specialist treatment for deep-rooted algae
This is when we most often conduct render cleaning. When your walls are heavily stained and they start to look rather not very nice.
The good thing about this is you’ll be breathing a breath of fresh air and feel like your home has been given a new lease of life once we refresh your render.
We’ll complete safe and effective cleaning using specific methods for your homes level of staining.
Following the cleaning we’ll apply a biocide treatment which retains an ongoing cleaning effect to keep future algae and mould at bay to protect your render from future algae colonisation.
Property Care & Protection
No damage to render, plants, or surrounding areas
Your home will likely have some vulnerable fixtures, fittings and features which demand care and protection to avoid damage.
These can include coloured doors, fixtures, window frames or even lead flashings that can be discoloured if they are not protected from exposure to cleaning agents.
For every render clean we conduct, we complete a site survey and identify all vulnerable points and include protection measures as part of the service.
Our included site survey avoids a potential error which could cost hundreds of thousands to put right which is why we make that investment upfront and plan our render cleaning processes specific to your home.
Safety & Competence
Fully trained, insured, and compliant methods
Perhaps the most important considerations.
Health and Safety is vital here. Effective render cleaning requires the use and application of chemicals to ensure a long lasting result.
Unfortunately, many businesses save costs by using generic industrial bleach products and practice insufficient health and safety measures.
This puts your family and home at severe risk since these chemicals can harm humans and your property.
We are proud to be a City & Guilds Assured Softwashing Professional having completed training with Chris Cloke who is perhaps the most qualified professional in the UK.

Frequently Asked Questions
for Render Cleaning in Wiltshire
Will pressure washing clean my render safely?
In most cases, no—we do not recommend pressure washing for render.
Here’s why:
- Surface Damage
High pressure can strip or weaken the outer layer of your render, making it more vulnerable to future staining. - Patchy Results
Render has a consistent colour, so uneven cleaning becomes very noticeable. - Short-Term Fix Only
Pressure washing doesn’t treat the root cause (algae inside the pores), meaning staining often returns quickly.
Instead, we use a soft washing approach, which delivers a deeper, longer-lasting clean without damage.
