Tips to help you avoid mould and condensation in your home


11 October 2021

As the temperature drops, this can create conditions for mould to form in your home. We've plenty of ways for you to prevent this – and remember, condensation is a natural occurrence, it doesn't mean you already have mould.

Mould occurs when warm moist air comes into contact with cold surfaces, and you might notice a strong, musty smell. Mould can affect your health making breathing difficulties worse, and causing allergies, skin rashes and coughing.

How can I avoid mould in my home?

To avoid mould, you should maintain a balance between heating and ventilation in your home.

The following tips will help you to avoid mould and condensation in your home:

  • Keep your home warm for as long as possible, at a temperature of at least 20°C
  • When your windows steam up, open them slightly to create an air gap, but still keeping in the warm air
  • Keep trickle vents open and use your extractor fan. Keep them clean and free of dust
  • Dry clothes outside if you can. If you have to dry indoors, don’t use radiators all over your home. Instead, hang out your laundry in the bathroom with the door closed and the extractor fan on
  • Use pan lids while cooking until the liquid cools, and keep the extractor hood or fan running to help get rid of any moisture
  • Keep your kitchen and bathroom doors closed when they’re in use, and open windows slightly to produce an air gap to help any mechanical fans
  • Don’t use gas or paraffin heaters as these create too much moisture
  • Wipe down any excess water immediately and make sure you clean away any black mould as soon as you see it, so it doesn’t get a chance to spread
  • Keep rooms and storage cupboards as clutter free as possible to allow good airflow throughout your home
  • Move furniture away from walls and let the fresh air in on bright sunny days to reduce humidity levels.
