Mould growth is associated with condensation and is grows as a result of long term untreated condensation. Mould spores are generally present in the atmosphere and normally do not cause a problem due to their low levels and will not settle on dry surfaces but will settle and generate growth when they land on constantly damp surfaces where thet will germinate and develop into heavy mould growth which in turn releases vast numbers of spores which is not only unsightly but can become a health risk particularly those prone to asthma. Mould can be treated by different chemicals on the market, some more effective than others, but the best remedy is to reduce the level of condensation thus eliminating an environment which encourages it’s growth. As can be seen Mould is not an indicator for the presence of rising damp.
