Huge problem with condensation on the window

Hello,

what makes me suspicious is the missing indication from you that other tenants are experiencing the same. Therefore, I assume that it is solely due to your previous heating/ventilation behavior.

I think I will maybe try for another week to ventilate/heat the apartment properly and diligently. But what if not much changes? Is it supposed to be decided by the housing company? If all of this is only our fault, then we have to swallow it. Something has to change anyway.

If you were to move into a single-family house built according to today's energy saving regulations, it would take about 2 years for the last remaining moisture (although the stones are mostly glued and "only" a lot of moisture comes into the house through the screed) to escape from the new building (with constant heating/ventilation). So how can you assume that your apartment can be dry after a few days - and only recently with correct heating/ventilation behavior? I want to assume that it will still take quite a while until the outer walls are reasonably dry.

Rhenish greetings

I have mentioned before that our neighbor (below us) also has problems with condensation on the window, but not as severe. And I don’t know how long I should wait and continue observing, that’s why I’m asking. We will have to paint the walls with an anti-mold agent and redo the wallpaper in the apartment anyway in the summer, I just don’t want the same story to happen every winter.

I would like to ask again how the apartment is ventilated. Are there, for example, window rebate ventilators on the windows? Is there a fan in the bathroom that constantly runs on a low setting and extracts the air? Are there any other air inlets and outlets in the apartment?

there is none of that in the apartment.

Hello falka,

I once had a similar problem in a small apartment. Now – after reading here – I know that it was not the ventilation, but my heating behavior that was the cause.

If there is no ventilation option in your bathroom, you should definitely open the window for 10–15 minutes immediately after showering/bathing. Otherwise, the moisture generated will spread throughout the entire apartment, since there is no way for it to escape. However, I think – since you’ve had this problem for a long time – that you probably already do this anyway.

I also think that drying out the apartment is a longer process. Nevertheless, in my opinion, the moisture should continue to decrease in the near future (at least there shouldn’t be any more waterfalls – fogged-up windows will remain longer). If the problem does not decrease by next summer, you could possibly consider moving.

Since you registered with MeckPom and are reportedly studying, I guess Rostock, Greifswald, or Schwerin as your place of residence. I can’t assess Schwerin, but in the other two cities, apartments of comparable size/price range should be available.

With this tip, I am probably just attracting the annoyance of , since this shifts the solution of the problem onto the landlord – but it would be an alternative if nothing changes in the medium term.

I recently consulted Aunt Google on the topic of "foggy windows and new building block" and found similar questions in other forums. This often concerned apartments on the upper floor of the new building blocks. Maybe this is a general problem and would explain why your subtenant does not have the problem. Then the neighbors to the left and right would have to have the problem just the same.
