Understanding Damp and Mould: Causes, Types, and When to Call a Professional

Damp and mould are common problems that can affect any home, causing damage not only to the look of your home such as paintwork or mould patches, but also serious health issues. Understanding the different types of damp, their causes, and when to seek professional help is crucial for maintaining a healthy and structurally -maintained living environment. 

Types of Damp

1. Rising Damp: This type of damp occurs when groundwater rises up through the walls and floors of a building by capillary action. Signs of rising damp are damp patches on walls typically up to about 1 meter high, peeling paint or wallpaper and musty smells. Rising damp is typically due to a lack of damp proof course, which stops damp from rising into the property. This is something we specialise in!

2. Penetrating Damp, also known as lateral damp, happens when water penetrates through the walls from the outside. Signs of this are damp patches on walls, ceilings, and floors that may darken after rain, musty smells, and possible mould growth. Structural issues like cracked brickwork, leaking roofs, blocked gutters, and poorly fitted windows and doors are a typical cause of this kind of damp as they are not effectively keeping moisture out!

3. Condensation is a type of damp that occurs when moist air inside a building comes into contact with cooler surfaces, resulting in water droplets. Signs of this are water droplets on windows and walls, black mould spots, and damp patches. This is typically caused by poor ventilation, inadequate heating, and activities that produce high humidity levels, such as cooking, showering, and drying clothes indoors.

4. Mould can appear as a white fully texture or sometimes even green. All types of mould can be toxic but black mould is the most dangerous type of mould and poses a serious risk to health. It can cause respiratory issues, allergic reactions, and in severe cases, toxic exposure that can lead to death.

   If you have black mould in your home, it is important to seek out a professional!
