Condensation on the window - you know it too? Here you can learn the best tips against wet windows from the inside!
Outside the temperatures drop and already water accumulates at the window. Especially in the morning, the drops on the window need to be wiped away.
In small quantities, condensation is not a problem. But if you have wet windows all the time, mold can form on the window and in the corners.
But why does the moisture settle just inside the window and what can I do about it?
We've done the research. With these 4 tips you are armed and say the fight against wet windows!

Why does condensation form on the window?
Why condensation makes windows wet is quickly explained.
Condensation is nothing other than moisture. This is present in the room air in the form of steam.
Warm air absorbs more moisture than cold air. If the warm room air cools down at the window, the vapor condenses and the windows become wet on the inside.
Attention: How to ventilate properly in summer!
Especially in cold seasons, wet windows often occur. This is because the temperature difference inside and outside is very high.
The colder it gets, the less water vapor the air can absorb. It releases the moisture to the window, as this is usually the coldest place.
But condensation can also form due to defective windows or incorrect ventilation.
When showering, cooking or hanging laundry out to dry in the living room, there is also a risk of too much moisture in the air.
Especially affected are kitchen, bathroom and winter gardens.
Each window has three weak points where condensate can form
- on the window frame
- on the surface of the glass
- between the window frame and sash
The colder it gets outside, the drier the air. On a really cold day, the air can hardly absorb any water vapor. So the vapor collects in the form of condensation on the window.
This is also the reason why fogged windows occur mainly in the winter months. It is cold outside and the humidity of the room collects on the cold windows.
TipTherefore now all clean their windows with rinse aid!
New buildings are particularly often affected by wet windows
Even if you would not suspect it at first: New houses and apartments tend to have condensation on the window. The reason is the particularly well insulated facades and airtight windows.
Very frequent ventilation is particularly important here. Often an air exchanger or ventilation system is already installed to take care of the indoor climate.
With older and not completely tight windows, air exchange often takes place automatically. However, a lot of heat is also lost here.
How to avoid condensation on the window when drying clothes
Have you ever noticed that the windows are really wet after hanging laundry? Logical. The moisture that forms in the room has nowhere to escape.
That's why you shouldn't hang up wet laundry in winter. Easy to say, isn't it?
If you don't have a dryer, you should put in an extra spin cycle. And put the laundry outside for at least 30 minutes before bringing it in.
If you live in an apartment block, there is often a place to hang laundry in the basement or attic.
No dryer, no balcony, no other way to hang up laundry? Then you should air the room well before hanging up the laundry, 30 minutes afterwards and after the laundry is dry.
But drying laundry in the room has another big disadvantage. Your heating costs will increase significantly.
The humidity of the room must be additionally heated during heating. Your heating system must therefore heat more so that the room is warm.
What you can do against wet windows from the inside
Condensation is constantly forming on your windows? With these tips you are finally rid of wet windows!
Remove condensation
Are your windows wet on the inside? Then you should definitely wipe the water away first. If it is not removed regularly, it can lead to mold or other damage to windows or walls.
Unfortunately, I also have this problem every day. So I grab an old towel in the morning and wipe all the windows dry. Then wring the towel out tightly, air it, and put it on the heater.
Ventilate properly
To prevent condensation from forming on the window in the first place, you should ventilate regularly. And you should ventilate every now and then.
To do this, open the windows fully and ventilate for about five minutes. Turn the radiator to zero during this time. Airing three to four times a day is ideal.
Follow these tips for proper ventilation in winter!
Ventilation is particularly important in the evening just before going to bed, in the morning after getting up and after showering.
The air is exchanged more quickly without cooling down the rooms. If you tilt the window instead, hardly any air is exchanged and the heat in the apartment is lost.
Create healthy indoor climate
Heating is also an important point to prevent condensation on the window. Make sure that the room temperature remains constant. The ideal temperature is different for each room.
In the sleeping area 18 degrees, in the living room and bathroom 23 degrees and in the basement 16 degrees are optimal. Humidity should be about 40-50%. In the bathroom 70% are okay.

Set on tight windows
Despite proper ventilation and the ideal room temperature, your windows get wet inside? Then you should definitely replace them.
With the right window model and proper installation, you can fix the problem permanently.
You can see how much condensation can damage windows, especially if the frames are made of wood. They begin to mold and will disintegrate after time.
Modern windows usually consist of several panes of glass. Between them is a sealed cavity. This serves as thermal insulation and prevents water from settling on the windows.
How mold develops due to condensation
If condensation makes windows, balcony door and co wet every day in the morning, then mold can occur.
But mold can appear not only on the windows, but also in the corners due to excess moisture.
If any is already present, be sure to get a mold cleaner.
However, to prevent mold follow our tips to make the moisture disappear from the rooms.
Attention: Especially in the bathroom, showering regularly creates moisture.
Our conclusion
Condensation on the window occurs mainly in winter. To prevent this, the ideal room temperature and proper ventilation is necessary. This also reduces the risk of mold appearing in the apartment.
