Condensation, damp and mould in the home
This guide will take you through how to identify different types of damp, mould and condensation, what causes them, what you can do about it yourself and how we can support you to deal with it.
What is condensation?
Condensation occurs when warm, humid air settles on cold surfaces and appears as water droplets. Everyday activities such as cooking, bathing, washing clothes and even breathing produce warm, wet air which can settle on cold surfaces like walls and windows and can cause damp and mould growth if left to build up.
What is damp?
There are several types of damp that can occur in your home. Damp happens when moisture collects and can’t fully dry out. It is usually caused by condensation and often occurs in areas with low air flow such as a bathroom when the extractor fan is not on or when the windows are closed. Damp can also be caused by problems on the outside of your home, such as a blocked gutter causing moisture to seep into the brickwork or broken tiles on the roof.
What is mould?
Mould is a type of fungus that grows in damp, moist conditions, often in areas with poor or low lighting and no ventilation. It’s normal to have some mould growth in winter but it needs to be cleaned and ventilated regularly to prevent it from getting more serious. It can grow on most surfaces where moisture is present, and may sometimes grow in places you cannot usually see such as behind wallpaper and under carpets.
