Damp and Mould

Cleaning your home

It is critical to report the issue of damp and mould to us as soon as it appears so we can do something about it.

Modern homes are often insulated, and whilst this limits draughts to keep warmth inside, it can also cause condensation.

What is condensation?

Condensation occurs when warm air comes into contact with cool surfaces, and mostly happens during cold weather and can cause mould and damp to gather where there is limited airflow, for example:

  • In the corners of a room
  • On the walls and ceilings
  • Behind furniture

Condensation is less likely to happen in warm and well-ventilated homes.

We generate moisture in our homes through everyday activities such as showering or boiling the kettle. 

Condensation can lead to mould growth if left untreated: there is an increased risk of developing respiratory problems.

Some people are more sensitive to mould than others, so reporting the issue of damp and mould to us is critical so we can act on it.

What is mould?

Mould refers to a type of fungi that can grow on almost any damp surface; often black and speckled but can also be green, yellow or brown. 

You may notice a damp or musty smell before you see any visible signs of mould; The reason for this is that condensation often forms behind cupboards and wardrobes where the air does not circulate.

To reduce the likelihood of mould occurring from condensation, the level of humidity in your home should be between 40% and 60% and the temperature between 18 and 24 degrees.
