Fact sheet: Damp, condensation and mould

Taking proactive measures to address damp and mould issues is not only crucial for maintaining your health but also your responsibility as a tenant.

Tenants, landlords, and letting agents must all play their part in implementing preventative measures to minimise the impact on living conditions and properties in Newcastle.

Understanding Condensation and Its Causes

Condensation occurs when warm air comes into contact with a cold surface, resulting in the formation of water droplets. If left unattended, this surface dampness can lead to the growth of mould. In the UK, this issue commonly arises due to insufficient heating of internal room temperatures and inadequate ventilation. For instance, if a house lacks proper heating and remains colder than usual, it can promote condensation.

Causes of damp and mould

When condensation is not properly addressed, it can lead to problems such as mould growth. Mould is a type of fungus that thrives on damp surfaces, often triggered by excess moisture resulting from condensation when walls and windows are cold and the air has high humidity.

In some cases, dampness can also be caused by penetrating leaks resulting from damage or decay, or by the absence of an effective damp proof course. Rising damp may occur in basements and ground floors due to these factors. It is important to note that rising damp typically does not lead to the growth of black mould.

Treating Damp and Mould

Damp and mould in residential properties can pose health risks and worsen existing allergies and respiratory conditions. Both tenants and landlords can take simple steps to prevent damp and mould. It is essential for everyone to understand how daily routines can contribute to dampness and mould formation in the house, and to adopt preventive measures to mitigate these issues.
