Render & Cladding Why Does Algae Grow On It ?

Render & Cladding Why Does Algae Grow On It ? Predominantly, there are a few ways that render and cladding becomes stained and dirty:

organic & atmospheric

To improve our render cleaning services, we’ve studied the science behind organic growth.

This has given us a greater insight and understanding of what is most likely causing your render to discolour or become damaged. We have developed unique treatments to ensure that your render remains in the best physical condition, free from both organic growths and any discolouration

Organic Stains

Algae and moss thrive best in damp, dark environments, so the worst organic growth on cladding will tend to be visible on the darker north and east elevations of a building. Organic
growth can occur in many shapes, sizes and colours, but is most commonly seen as a green hue across large sections of cladding. There are often a number of key geographical,
environmental and maintenance factors that will increase the likelihood of growth.

Geographically – buildings in close proximity to water, such as rivers, lakes
and seas, tend to have a greater build-up of organic growth due to the wetter.

Environmentally – buildings next to large trees and foliage will be more
prone to organic growth as spores can transfer easily from the trees
conditions.

Maintenance – where gutters and downpipes are poorly maintained, drips
can occur leading to increased moisture on the façade and subsequent
organic growth.

In addition to organic growth, birds roosting on the building may have very
serious consequences on the building façade, and if droppings are not
removed quickly the acidic nature starts to eat at the substrate.

Atmospheric Staining

Cladded/rendered buildings situated close to roads and located in busy towns and cities are often
more prone to developing general dirt and grime build-up on the surface. Although
the development over time may not be as noticeable as organic growth, the cladding/render
will begin to look faded and take on a dull grey appearance, particularly on lighter
cladding colours.

There are two fundamental approaches to the cleaning of buildings or masonry, both of which are offered to a high standard here at Cleaning Service UK. These are the physical approach and the chemical approach.In order to minimise the risk of corrosion or damage, not all treatments are suitable for all building materials. Extreme care must be taken when deciding which cleaning approach to take, which is where we excel over other contractors. We use our experience and knowledge to ensure your building is always cleaned without any signs of damage.
