Now that we are moving further into Autumn we are seeing more and more cases of condensation and black mould in properties. Black mould (also known as black spot mould or condensation mould) is a sign that there is an on-going problem due to condensation within the property. Black mould spores are omni-present within the environment and only when in the right conditions (where surface moisture is present) will they germinate and reproduce the black moulds that are commonly seen as a result of excessive condensation.

Here we have an example of an on-going condensation problem that  our Envirowise team of Air Quality experts have recently advised upon within a ground floor flat. The picture clearly shows black  moulds forming on the wall in a typical tortoise shell pattern. Left untreated the black mould would spread and cover the entire wall. Black mould spores are a well known trigger for asthma so need to be removed to maintain a healthy living environment. In the same picture we can see the solution to the condensation and mould problem that another company had suggested. Passive air vents, as seen in the picture,  help with the movement of moisture laden air within properties which in turn helps reduce condensation levels within the property. However, in some cases more movement of air is needed to help alleviate the condensation problem.

The solution to this black mould and condensation problem was simple – replace the moisture laden air within the property with clean fresh air!

Initially a mould eradication kit was used to remove the black mould and spores from the wall surfaces and sterilise the area previously inhabited by the black moulds.  Mould eradication kits are the only way to effectively treat mould infected areas. Mould eradication kits are available to buy direct from our on-line shop. To learn more about what the mould eradication kit contains we have a short video where our Air Quality expert gives more details. To view the video click here.

To move air within the property we installed a positive pressure unit. The positive pressure unit draws fresh, dry, filtered ambient air in from outside, and gently pushes it into the property. This causes a slight internal positive pressure, continually pushing out any moisture-laden air ultimately reducing the humidity levels to control condensation. For further advice on how our positive pressure units work visit our ventilation pages.
