Condensation dampness arises when a property is unable to deal with the amount of water vapour being generated. The presence of condensation can cause mould growth, excessive humidity and insect infestation. Mould growth poses a significant threat to health particularily to those who suffer from asthma.
Inherent design defects of a building cause condensation, and that causes black spore mould, which puts tenants at a high risk of respiratory problems including asthma.
Tower blocks and maisonettes are significantly affected due to cold bridging. This is because large blocks of concrete conduct cold into the property, leading to condensation forming on the resulting cold spots, causing mould. As this is caused by an underlying design defect then simply washing away the mould will prove futile and the problem will keep reoccurring.
The law did not previously cover condensation unless it was caused by disrepair. Recent changes to the law which came into force 20 March 2020 mean that legal action can be taken for condensation rendering a property unfit for human habitation. Therefore condensation caused by design defects affecting many buildings, particularly tower blocks and maisonettes can be rectified and compensation secured.
