It is possible to lower the amount of condensation in your home by making a few easy changes, as outlined in our video on managing condensation in your home.

Please note, if the cause of mould or damp is due to condensation then it is your responsibility to ventilate your home and clean the mould from surfaces.

Condensation is caused by moisture in the air – we have all seen it on windows in the morning.

There is always some moisture in the air inside your home. Everyday activities, especially cooking, washing, having a bath or shower and even breathing causes this moisture.

Condensation can cause black mould on walls, clothes, and furniture. This may look unpleasant and have a musty smell. In some cases, condensation can damage plasterwork and rot wooden window frames so it’s important to check regularly and clean any away with a mould cleaner as soon as it appears.

Mould often appears in places where the air can’t circulate, so you should regularly check in corners, on or around windows and behind furniture.


The best way to reduce condensation and mould is to make sure your home is well ventilated, meaning air can circulate.

Make less moisture

If there is less moisture in the air in your home, there will be less condensation. There are simple things you can do to reduce this such as putting lids on saucepans when cooking to keep the steam in, hanging laundry outdoors if possible or leaving it to dry in one room with the internal door closed and with a window open or extractor fan on.

Keep warm

Keeping your home at a consistent temperature can reduce condensation. Keeping the heating on low all the time can be more efficient and cheaper.

What looks like damp in walls and ceilings is normally caused by condensation. But there may be other causes, such as:

  • Leaking roofs, guttering or chimneys
  • Leaking internal or external pipes
  • A breach of the damp-proof course, or failure of rendering or brickwork.

If the damp is being caused by a structural problem, then we will carry out those repairs to the building. Please report this to us by clicking the button below:
