Do you have wet windows in the morning and are wondering how to prevent it? We have 4 tips to help you reduce condensation and protect your home from mold.
After the temperature drop, are your windows wet from the inside in the morning? A widespread problem. The bedroom and kitchen windows are particularly affected.
You should definitely not ignore this condensation on the windows. In the worst case scenario, it can lead to mold.
The most important thing in brief:
Caused: High humidity hits cold window surfaces, exacerbated by poor thermal insulation.
Danger: Mold formation and damage to building materials.
Prevent: Ventilate regularly, heat evenly, keep humidity at 40-60%.
Immediate assistance: Wipe off condensation directly and improve air circulation.
Long term solution: Replace old windows and improve thermal insulation.
Why are the windows wet in the morning?
Condensation on windows occurs when the humidity in the living room is highprevail. The water vapor contained in the air forms condensation on cold surfaces such as window panes.
The problem:If the humidity is too high, harmful mold can form. First of all, so-calledThermal bridges(often colloquially referred to as a cold bridge), but in the long term also on the walls.
According to consumer advice centers, a four-person household produces between six and twelve liters of water per day, which is released into the air through sweating and breathing. Pets and houseplants also release moisture into the air.

This helps against wet windows
To minimize condensation on the windows and find the right balance between temperature and humidity, you should follow these four simple rules:
- Wipe off the condensation daily with a dry cloth.
- Provide shock ventilation or cross-ventilation at least three times a day. It is better to ventilate four to five times a day for 5 to 10 minutes.
- You should always ventilate after cooking, showering, bathing and even after sleeping.
- Try to keep the temperature indoors as constant as possible. Or close the doors to other rooms if there is hardly any heating in them.
If you have problems with excessive humidity, aquariums, indoor fountains and many house plants can also be among the causes. In these rooms you then have to think more about ventilation and heating.
But be careful:In this case, continuous ventilation with the window tilted does more harm than good.
Another tip to further reduce the humidity in the rooms is, for example, not to dry your damp laundry in the apartment. Balconies, gardens, drying rooms, attics or even dry basements are more suitable.
Waterlogging behind curtains and pleats
One place where you rarely check whether condensation has formed on the window panes is curtains. In particular pleated blinds.
If these are pulled down to the bottom edge of the window, you won't see the condensation at first glance. But this is where moisture tends to build up. So remember to check what the moisture is like when you have all kinds of privacy protection behind it.
Ideal room climate to avoid condensation on the window
The ideal living environment should be loudConsumer advice centerat a temperature between 18 and 20 °C, with a humidity between 40 and 60%. However, the experts advise that the temperature in the apartment should not fall below 16 °C. So not heating at all is not an option either.
The room temperature also influences the humidity. Warm air can hold more water. Increasing the temperature can sometimes help.
Here you should be guided by the recommended temperature for the respective room. So it's best to get oneThermo-Hygrometer(here at Amazon*), so you can always keep an eye on the temperature and humidity.
Depending on the building structure and insulation, differences can of course occur. While high humidity of 60% is not a problem in a new building, even over longer periods of time, moisture damage can occur at levels as low as 40% in an older building.
Extra tip:If the humidity in your living space is constantly too high, even though you ventilate daily, heat properly and do not dry any laundry in the rooms, this may be a problemDehumidifierbe useful.

Adapt habits to living space
If the apartment or house has been renovated, the to-dos regarding ventilation and heating habits may also change.
For example, if the old windows in an old building have been replaced with modern windows, mold can sometimes form because the newer windows seal much more tightly and there is no longer any air exchange.
This is of course positive in terms of heating energy, which is lost less and also that it is probably more unfortunate than before.
But this is exactly the moment when you have to change your previous ventilation habits. If you have just moved into a new home, it is best to ask your landlord what the best course of action is for this apartment.
