In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. Low internal room temperatures can also create cold surfaces (particularly on windows and exterior walls) which allows warm air to condense onto them easily.
It happens mainly during the colder months, regardless of whether the weather is wet or dry. Condensation is completely normal and is the most common cause of dampness in the home, especially in colder rooms.
This is because the cold makes your property's walls and windows colder, and condensation is formed when the warm air inside your home that contains moisture comes into contact with cooler temperatures, meaning that the gaseous moisture contained in your properties warm air reverts back to a liquid state when it comes ...
Adequate heating
Adequately heating your home can help to reduce condensation and damp, so keep temperature levels consistent, especially in those rooms that you may not use often. A heating thermostat can be useful for this. Avoid using paraffin heaters as these tend to create excess moisture.
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. You don't need to keep your home at these temperatures all the time, but you should aim to bring it up to these temperatures at least some of the day.
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.
In fact not heating your house through the winter or colder months can cause real issues for buildings, especially if it has been heated previously, flooded or has a lack of ventilation or has damp problems. When the temperature drops, cold air outdoors, can increase the problems with condensation in the home.
Removing condensation
Make a habit of removing window condensation first thing every morning — when it's at its worst. Use an absorbent paper towel or microfibre cloth to gently scoop and wipe the water off the surface of your windows. Use a fresh towel or a squeegee to dry the pane thoroughly afterwards.
Sometimes condensation can be greatly reduced by changing what you do in your home. Try these easy tips for reducing condensation: Keep your heating on low all day in the cold weather. Wipe your window sills every morning.
In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. Low internal room temperatures can also create cold surfaces (particularly on windows and exterior walls) which allows warm air to condense onto them easily.
Opening the windows to reduce damp from condensation
Condensation occurs when humid, warm air becomes trapped in your home and then meets a cold surface, like a window. Opening a window allows humid air to escape from your home, thus reducing condensation.
For the most part, a little condensation on your home's windows is nothing to worry about. It's only when you have excessive condensation on the windows, or the condensation is between the window panes that you should be concerned.
First off, if it's cold in your home and it's moist and humid outside, that creates condensation…not only on your windows, but inside the home too. These wet conditions are perfect for mold and mildew.
If air temperature is 21ºC and relative humidity is 90% condensation would occur on surfaces at 19ºC or less. If air temperature is 21ºC and relative humidity is 100% condensation would occur on surfaces at 21ºC or less.
Condensation forms when warm, humid air contacts a cold surface. Moisture is in the air all around us and warmer air can hold more moisture. As air cools, it contracts and its moisture condenses.
If warm air cannot escape through an open window or air vent, it moves around until it finds a cold surface where it cools and forms condensation. Condensation forms more easily on cold surfaces in the home, for example walls and ceilings.
By opening the window we make the heating system work with maximum power. Although the radiator will become hot, the heated air will immediately escape through the window. It will therefore be a good practice to lower the pre-set temperature during ventilation.
To stop condensation on windows at night try keeping your bedroom door open to improve airflow and leaving your curtains open, or swapping for a thinner material. If this doesn't fix the problem, check the seals of the windows (as mentioned above) or consider running a dehumidifier at night to keep moisture at bay.
Although condensation doesn't signal that you need new replacement windows, it's still possible that you do need some. If you've had your windows for years and you notice that they are a little drafty, then you may want to consider investing in new windows.
As the mornings get colder, you may have noticed condensation forming on your window panes. You might be surprised to know that it's completely normal. In fact it could be a sign that your new windows are doing their job.
Internal condensation
This is generally caused by the room not being double or triple glazed, not being sufficiently heated and/or being shut up so the air doesn't move around enough. The upshot is too much water vapour in the room and windows which are cold enough to attract it.
Ventilate your home
Mokler recommends even opening the windows for just 20 minutes a day as this can be enough to drastically reduce the effects of condensation and dampness in homes.
