Condensation - Mould & Damp

Condensation can happen in your home.  Our expert tips are designed to keep your home clear of condensation - what’s more they really work.

Please be aware that virtually all cases of condensation are caused by the way the property is used by the people living in it. Therefore GGHT WILL NOT compensate any resident for damage of personal items or household goods/ furniture that has suffered from the effects of condensation. It is the responsibility of the tenant to ensure the way the property is used does not create condensation in the first place.

​During winter, when we keep the heating on and the windows closed, condensation can become a problem. But not only is it a big cause of mould, it can irritate chest problems too. So how do you tackle condensation? We asked our Propertycare experts for their advice on simple steps that really work - click on the images to see our short films.
1. Cooking causes steam and steam creates condensation
Reduce both by keeping pan lids on whilst cooking and ​using your kitchen extractor fan if you have one.​​

2. Close the door when you’re bathing
Running water for baths or showers causes clouds of moisture and condensation. Always open the window or use an extractor fan is you have one and keep the door closed to stop the moisture spreading about.​​

3. Damp clothes are moisture makers
Try and dry washing outdoors if possible and not on radiators​. Or, if you’re using a tumble dryers, make sure the outlet pipe goes through an outside wall to carry steam out of your homes.

5. Open windows keep air circulating 
When it’s cold, it’s tempting to keep windows closed but opening them for a few hours a day (while you’re out or at work) can make a big difference.  When a room is in use, keep a small window and/or a trickle vent open.

6. Furniture
Ventilate cupboards and wardrobes - do not overfill wardrobes - let the air circulate freely inside. Move it 50mm away from the surrounding wall. If possible, locate wardrobes against internal partition walls.

6. Heating, insulating and draft proof your home 
When the whole house is warmer, condensation is less likely.  The use of your central heating at low levels provides the most economical form of heat, rather and reduces the likelihood of condensation.  Usually this needs to be between 18c-22c and keep the heating on low all day in very cold weather, even when there's no one at home.  If you are concerned about your heating bills, visit our Energy Advice page for more information on saving money on your energy bills​.​  

In most cases, mould and condensation can be avoided just by following the top tips above or by downloading the GGHT condensation leaflet (pdf).
Accordion Description
  • Condensation is cause by moisture in the air caused by cooking, washing, bathing and even breathing.
  • There is always some moisture in the air, even if you cannot see it.
  • As the air gets cooler it can hold less moisture, so droplets of water appear, especially on cold surfaces – this is known as condensation.
  • Everyday examples of condensation are when you see your breath in cold weather or when your mirror mists up when you have a bath.

The build up of condensation causes black mould on walls, furniture, clothes and curtains.  The residue left by condensation can damage the plasterwork and decoration.  The moisture in the air and the spread of mould can affect your health especially if you suffer from chest or breathing problems.

Every home gets condensation at some time - usually when lots of moisture and steam are being produced such as bath times, when cooking meals or washing/drying clothes.  It is quite normal to find your bedroom windows misted up in the morning after a cold night, It does not mean you have a serious condensation problem.

If your home never seems to be free from condensation, or you have mould growth as well, read on.
​By law, we are only responsible for condensation that has been caused by damaged items that we are responsible for repairing.  These are listed in your tenancy agreement, but include the following:
  • The structure and outside of the building.
  • The services for supplying water, gas and electricity.
  • The facilities for getting ride of waste and foul water.
  • The installations for space and water heating.
​​​If condensation has caused patches of mould around your home, there are a number of ways you can treat it: 
  1. Wipe down windows, frames and affected areas with a fungicidal (mould-killing) wash. There are various products on the market that will help such as fungicidal products available in DIY stores.  Choose one that is Health and Safety Executive approved and follow the instructions precisely
  2. After treatment, redecorate using a good quality fungicidal paint. Where possible remove lining papare and wallpaper, treat the plaster then paint or paper again
  3. Dry clean mildewed clothes or furnishings and shampoo mouldy carpets
  4. Consider using a dehumidifier
  5. After treating mould-affected areas, redecorate using a good-quality fungicidal paint. Where possible remove lining paper and wallpaper, treat the plaster and then paint or paper the area again.
  • ​​When the whole home is warmer, condensation is less likely.
  • Make sure you close your curtains at night.
  • Use central heating to warm up the whole house rather than heating a single room with a gas or electric fire. 
  • Insulate your loft (but don't block the openings or under the eaves).
  • Keep the heating on low all day in very cold weather, even when there's no one at home.
  • Draught-proof windows and doors (except in bathrooms, kitchens or rooms with a cooker or gas fire as this can be dangerous).
