Render Cleaning Services

Our results on render cleaning speak for themselves.

From Weber Monocouche Render to K-Rend and on to Sto, we clean all types of render that are now in widespread use on buildings across the UK. This contemporary material is not without its problems and needs regular maintenance to keep it looking at its best. We see a number of common problems with render and have developed unique and affective methods to deal with these issues.

Have a look below at some of the projects we have tackled recently and some of the key services that we offer. Chances are that you have the same issues and we can help.

Red Algae Growth Removal

The genus Trentepohlia would not at first glance be taken as a green alga. Free-living species are mostly yellow to bright orange or red-brown in colour due to the orange pigment, haematochrome (b-carotene), which usually hides the green of the chlorophyll. The genus is terrestrial and is often found in Europe on rocks, walls and tree bark. Where they are found on buildings, they can cause severe mechanical degradation and deterioration. When treated correctly, the organic growth can be completely removed from render.

Mould Growth Removal

There are a range of organic moulds and algae that grows on render, the most difficult to treat are the filamentous fungi as their structure keys into the porous render substrate making it hard to remove. The most common species found in this country are the Cladodporium spp and Alternaria spp and both metabolise a black pigment which protects them from UV radiations. It is this pigment which causes an unsightly staining on the render and if left unchecked can lead to severe mechanical degradation of the surface.

Green Algae Growth Removal

Much easier to treat than mould, green algae grows quickly on render favouring the shadier north facing elevations. Our sensitive treatments are 100% effective in removing this organic growth and restoring the render back to its original colour.
