Permanently dry damp windows


In the cold season, moisture often collects on the window frame, which drips on the lower framing and forms puddles there. If you do not solve this problem quickly, you will face mold growth in the next step. Luckily there are sustainable methods to permanently dry the damp windows.

Moisture on the windows: What can I do about it?

Moisture collects inside your windows? First of all, this is due to the fact that water from the warm indoor air always condenses at the coldest point in the room - this is often the window pane.

Therefore, this phenomenon is also observed mainly in the cold season, because then the temperature difference is particularly large. There are several ways to tackle wet windows:

The first variant deals with reducing the humidity in the room so that no more water is deposited. Other methods have the goal to get the window tight, so that the double glazing works again sufficiently.

Prevent condensation on the window - reduce humidity

Regular airing: Often the cause of damp windows is that the humidity is not regularly reduced by airing. Then the warm room air continues to accumulate with fine droplets of water that settle you on the windows.

Thoroughly vent the air in each living room three times a day, monitor the humidity with a hygrometer, and above all, ventilate after cooking or showering.

Especially with well-functioning insulating glass windows, the formation of condensation is often due to inadequate ventilation. Here, the temperature difference between the pane and the room is particularly low.

The right room temperature to avoid wet windows

The room temperature can also contribute to water settling at the window. The warmer the air, the more humidity it can absorb in everyday life, which is why condensation often occurs in subcooled rooms.

Preheat your living space to at least 20 degrees Celsius without forgetting to air. If a little water still forms, wipe it regularly with a soft cloth to prevent mold growth.

Dry damp windows - repair cold spots

For older windows, it seems likely that they contain thermal bridges due to aging or unfavorable construction. At cold bridges, the room heat is directed outwards particularly quickly, they themselves and their environment cool above average.

In addition to the formation of condensation, this entails a high energy loss which it is worth remedy. These options are available:

  • Service seals regularly and replace if necessary
  • Clean and grease gaskets if necessary
  • Renew putty on old wooden windows
  • Replace glass panes with insulating glass
  • Check correct installation of the windows - have them repaired
  • Replace window completely

Tips & Tricks

Some modern windows even have an integrated ventilation system that acts as a room climate regulator. This also prevents condensation in winter.
