Break The Mould (Condensation & Damp)

By ELeyshon 14 Nov 2017

Condensation and mould can be quite common in student houses, but it's not always due to defects in a property.

It is usually caused by the way tenants are living in the house, so by altering the way that you live, you can address these issues in your home.

You'll often hear about damp problems, but it's actually condensation.


What is condensation?

The air in your home will always contain a certain amount of moisture. This does not normally cause a problem. However, when air gets cold, it cannot hold all the water produced by the occupier’s normal everyday activities, so small droplets of water will form. This is condensation. These droplets usually form on cold surfaces such as windows, mirrors, tiles and external walls. It is also common in areas where there is little movement of air such as in corners and behind furniture.

How to treat condensation?

To kill and remove mould, wipe down affected areas (e.g. walls and
window frames) every few days with a fungicidal wash. (This should have a Health and Safety Executive approval number and you must follow the manufacturer ’s instructions carefully). This should be part of your regular cleaning routine.

What causes condensation?

  • Too much moisture in your home
  • Not enough ventilation in your home
  • Inadequate heating

How can I prevent condensation in my home?

Produce less moisture and increase ventilation by:

  • Drying clothes outside
  • Opening all windows if you must dry clothes indoors
  • Avoiding drying clothes on radiators
  • Closing kitchen doors when cooking
  • Using lids on pots and pans when cooking and opening kitchen windows
  • Closing bathroom doors when running a bath or showering
  • Using extractor fans in kitchens and bathrooms where available
  • Keeping windows ajar in bedrooms overnight
  • Not over occupying your home (more people means more moisture)
  • Making sure air can circulate in wardrobes and cupboards by not overfilling
  • Keeping furniture away from external walls to ensure that air can circulate in these areas

You can ensure your home is adequately heated by:

  • Keeping your heating on low throughout the day during colder weather
  • Trying to heat all rooms in your home as condensation can be worse when some rooms are warm and others are cold
  • Making sure that your home is
    adequately insulated

I've tried all these suggestions but I've still got a problem. What should I do?

You should always speak to your landlord in the first instance regarding any concerns about condensation and mould in your home. A Council Officer can visit and inspect your home if necessary.
