Condensation commonly appears on windows in living rooms, bathrooms, kitchens and bedrooms, and happens in many households when the temperature drops inside the house, especially at night time when the heating is turned off. These droplets of moisture are formed when warm air inside our homes, hits a cold surface such as a wall or window, where it will then appear as condensation.
Condensation can cause problems in your home, including black mould which can damage possessions and even affect your health. Read our top tips on preventing condensation in your home, and what to do if you find mould...
During your bath or shower, and after, keep your bathroom door shut and the window open. This will allow air to get into the room to dry excess moisture, whilst preventing cold air from travelling all through your home. Where possible, always use an extractor fan.
When the weather allows, dry your clothes outside. If that isn't possible, try to refrain from drying clothes on radiators as this will create water vapour. Instead, place them in a cool room on a clothes rack and keep the door closed. Ensure any tumble driers are also properly ventilated.
When washing clothes or cooking, keep the kitchen door shut and open a window. Use an extractor fan where fitted and keep the lids on pans when cooking.
Try to keep your home at a consistent temperature (at least 15 degrees in cold weather). We understand it can get costly to heat your home through winter, so take care to close windows at night and exclude any draughts.
Air bricks/flues and air flow
Ensure that you do not block up or cover air bricks, flues or ventilators. Not only does this increase the likelihood of condensation, this could also be dangerous. Always ensure that furniture is not blocking air vents, and leave a gap between your furniture and walls.

If you see patches of black mould in your home, it means that you already have condensation in your property and these affected areas will need to be treated.
Carefully remove mould with a damp cloth, and then throw it away.
Wipe down any affected areas using a fungicidal wash or diluted bleach - remember to always wear rubber gloves, safety glasses and old clothes/overalls.
Redecorate the area following treatment using a fungicidal paint or wallpaper paste - do not paint over using ordinary paint as the problem will likely return.
