What is condensation, damp, and mould?

Damp and mould are common household issues. It is important to understand what causes it and what can be done to prevent it.

Condensation

Condensation is when warm, wet air settles on a cold surface and water droplets are formed. These water droplets are called condensation.

Condensation mostly happens in colder months when it is both raining and dry outside. Moisture moves through a property and settles in colder rooms.

Condensation should be wiped away daily. If left, it can lead to mould growth.

Damp

Damp can form when moisture collects in an area and does not dry out properly.

Moisture occurs in homes through day-to-day activities such as bathing, cooking, and drying clothes.

Moisture can also get into homes from outside sources, such as a leak or broken and blocked guttering.

When moisture cannot get out, it can lead to damp and mould. The best way to avoid damp and mould is to ventilate homes daily. This allows the air to circulate.

Mould

Mould is essentially a fungal growth that forms where there is moisture. It first appears as black pinpricks on walls, ceilings, and furnishing and can have a musty smell.

Mould grows because of moist conditions. If condensation and damp are not dealt with quickly, it can lead to mould.

Mould can spread very quickly and can become extremely hard to get rid of.
