What is condensation?
Condensation happens when warm, moist air comes into contact with a cold surface, such as a window or external wall. Water droplets then form, which can lead to damp conditions and mould growth if left untreated.

Understanding Condensation, Damp and Mould
What is damp?
Damp is unwanted moisture within a property. It can be caused by sources such as leaks, rainwater entering the building, rising moisture from the ground, or poor ventilation that allows moisture to build up indoors.
What is mould?
Mould is a type of fungus that grows in damp environments. It often appears as black, green or grey patches on walls, ceilings, windows and other surfaces. Mould can damage decorations and belongings and may affect indoor air quality.
Why Do These Problems Happen?
Moisture is created every day through normal household activities such as showering, cooking, washing clothes, and drying laundry indoors. Without effective ventilation, this moisture becomes trapped inside the home and can build up over time. When warm, moisture-laden air comes into contact with colder surfaces, condensation forms, creating the ideal conditions for damp and mould growth.
If your home has no ventilation system or an inadequate extractor fan, excess moisture may not be removed effectively. Good ventilation helps to control humidity levels, preventing condensation and mould while improving indoor air quality and comfort for everyone in the home.
