Red Algae on Render
If your building is suffering from red algae on render, chances are it is finished with a coloured render like K-Rend. It is porous and susceptible to the red and green algae colonisation you are experiencing. You can also see it on unpainted plastered walls and unpainted roof apexes. These through coloured renders are an excellent finish to modern buildings. Generally they are fairly low maintenance eliminating the need for painting etc.
Expert Cleaning Services for Red Algae on Render
There are several reasons for Red algae on render. The Algae blooms usually occur on walls that remain damp, this can be North facing, leaking gutters or just naturally shaded areas . Those over hung by trees or in the shadow of a neighbour’s property are a common example.
Professional Red Algae Removal Service
We specialise in the treatment of Red algae on render. We can also treat the green and black marks on the render that usually accompany it. Depending on the severity of the growth we have several options for cleaning it. First we identify the type of Algae. The Green and Red algae on render is easily cleaned with a simple application by low pressure of a bio-degradable biocide.
Within hours the growths die and the wind and rain is left to gentle wash away the debris.
One most domestic properties we can carry out the work from the ground, eliminating the cost of expensive scaffolding etc.
Thus keeping the service affordable to home owners.

What happens if you let red algae on render grow?
- Make the building look neglected or poorly maintained.
- Lead to deeper staining that becomes harder to remove.
- Cause potential structural issues by trapping moisture against the surface.
Signs That Your Render Needs Professional Cleaning
Many property owners dismiss red algae as a minor issue until it becomes an eyesore. Early signs that indicate you need professional treatment include:
- Patches of Red or Green Growth – Initial algae spots may seem minor but can spread quickly across large areas.
- Black Streaks or Stains – These often accompany red algae and indicate prolonged exposure to damp conditions.
- Discolouration & Dull Appearance – If your render looks faded, it may be covered with microscopic algae growth that will soon become visible.
- Rough or Powdery Surface Texture – This could indicate deep algae penetration that requires immediate treatment.
