Condensation is becoming one of the most common causes of dampness in buildings and is nearly always associated with black mould growth (Aspergillus Niger).
The problem arises because of high relateve humidities, a lack of natural ventilation and, in most cases, cold external walls. Sometimes it is possible to reduce humidities by regulating activities like drying clothes indoors. Ventilation can be provided via trickle vents etc. but these are usually ineffective due to perceived heat loss or cold draughts.
Mould growth is a typical consequence of condensation problems in a home. Moulds are often most severe in room corners and on external walls. This is mainly because insufficient ventilation creates pockets of stagnant air in such corners.
