Open the windows
Keeping your window slightly open through the night will release warm, damp air from your home and give you a good chance of getting rid of condensation on windows. Use trickle vents and lock features to keep your window secure while allowing air to circulate the room.
Condensation occurs when warm air collides with cold surfaces, or when there's too much humidity in your home. This is especially common in winter, when your central heating system comes on in the cooler hours of the mornings and evenings.
Removing condensation
For example, excess water can cause window seals to warp and loosen, while the excess damp can lead to mould and respiratory problems. Make a habit of removing window condensation first thing every morning — when it's at its worst.
Dehumidifiers seem to be the obvious way of reducing humidity, removing condensation, stopping walls becoming damp and preventing mould. But a more effective solution is to give your home a small but consistent background movement of fresh air. This will help keep your home feeling fresher, healthier and mould free.
To help with clearing the condensation away, you can make a simple, home-made solution by mixing two cups of water with two cups of white vinegar and a couple drops of washing up liquid. Pour this mixture into a spray bottle if you have one and spray the solution straight onto your window.
Open Your Window
This might seem obvious, but it's effective. Opening your windows will release the humid air outside, and therefore, will prevent the humidity from collecting onto your windows. So, if it's not too cold out and you're suffering from condensation, open a window.
Install double glazing to reduce condensation
The reason we see so much condensation on single glazed glass is that the glass is susceptible to cold and stimulates the dew point from the water vapour in the air. Double glazing helps to reduce condensation because the glass is not as cold as single glazed.
The warmer the air, the more water and moisture it can hold. Therefore, heating can help with excessive damp because it increases the water-holding capacity of the air and makes it, as a result, less likely to become saturated.
The World Health Organisation guidelines suggest 21 degrees in a living room and 18 degrees in the bedrooms, falling lower at night and when you are out.
Once humidity levels in the home are brought down to below 60%, airborne bacteria and viruses will not only stop breeding, but will struggle to survive. To control heavier cases of condensation on windows, damp or mould, it is advisable to bring the humidity down to 40% during the winter months.
What causes condensation? Condensation occurs when hot, moist air hits cold, dry air. This meeting causes water droplets to form on the cold surfaces (like your walls). This kind of moisture is what you'll find on the bathroom walls after a super-hot shower.
The most popular DIY dehumidifier is the one that works the best—rock salt. Rock salt naturally absorbs moisture out of the air, making it a great choice to use as a dehumidifier.
Blinds can't cause condensation due to the fact they do not produce moisture or heat.
Wipe windows, walls and mirrors to remove condensation (a microfiber cloth is the most efficient means of doing this), and dry the shower tray or bath. Keep the door closed while the bathroom is in use to prevent to steam escaping to other parts of the house.
Just keeping your window open for a short amount of time each day can significantly reduce indoor pollution and bring fresh air inside to dilute any toxins. In winter, especially, air can become old and stale quickly, so you'll want to keep things fresh and clean.
Allow the room's warmth to reach the windows. Position heaters under the windows and place curtains at least 15cm to 20cm away from the glass to allow free movement of warm air. Moist air takes more energy to heat than dry air, so opening a window to let out damp wet air will help a room feel warm and dry faster.
One of the best solutions to condensation is to heat up your home. Central heating is a perfect way to heat your home and stop fluctuating temperatures that cause condensation.
We don't mean start drying your hair as soon as you've gotten out the shower. Instead, as a small house hack, use your hairdryer to remove any condensation build-up around your double glazing.
