Hello everyone,
a quick overview of the situation:
The idea is to install electric roller shutters, properly insulate the shutter boxes, and possibly replace the window seals.
Will this solve the mold problem?
Thanks for your input
a quick overview of the situation:
- We have a house where windows were ventilated with three quick air exchanges daily.
- There are radiators under the windows (removed for renovation).
- The windows are double-glazed.
- The windows have manual roller shutters that are not well insulated.
- There is also some mold on the second sealing layer at the window.
- The problem occurs in every room at every window.
- All walls are covered with wallpaper and there is laminate flooring.

Will this solve the mold problem?

This will be the coldest corner of the room. Exterior corners of houses often are. Combine that with moisture and low heating = mold. This can be resolved a) with plenty of heat and ventilation or b) by adding internal insulation.
Tighter windows make the situation worse.
You will need to assess how the situation is in your case. It’s not even a corner of the house, but the side wall. However, the problem occurs at all the windows and even at a house corner without a window, there are a few small spots in the upper corner.

But the problem exists at all the windows, and even at a house corner without a window, there are a few small spots at the top of the corner. Windows have nothing to do with the corners (only indirectly through ventilation). It sounds more like you have a fundamental issue. Whether it is related to your usage (too little heating, insufficient ventilation) or the building structure, a professional needs to inspect it on site.

Yes, there was also a cabinet placed 5cm (2 inches) away. The problem can be solved by increasing the distance. The question is also why there is mold or always condensation on the windows. The house is about 30 years old. 30-year-old uPVC windows generally have poor insulation values, and if the seals have never been replaced and the hardware hasn’t been adjusted, they simply won’t be properly airtight anymore. This leads to condensation forming quickly. Overall, this seems more like a fundamental building structure issue and is unlikely to be resolved just by better ventilation or tighter windows.
HausiKlausi3 May 2021 23:21Was the house vacant for an extended period? Apart from the explanation already provided here regarding cold bridges at the timber frame corner, I find it hard to understand the mold around ALL the windows—in an occupied house that is heated reasonably according to common standards.

Aside from the explanation already given here about thermal bridges at the corner of the timber frame, I find it hard to understand the mold appearing on ALL the windows—in an occupied and reasonably heated house by common standards.The house, or rather the apartment, was never empty. It was always heated but also often ventilated with windows tilted open.Who would you typically have inspect and assess this?
Thanks to everyone for the feedback so far!
