Good day,
I am new here and hope you can help me (even though I am not currently building myself):
We recently moved into a newly painted apartment on the third floor; the building was constructed just before the turn of the millennium.
I noticed that the windows, especially in the mornings in the bedroom, office, and kitchen, are fogged up on the inside edges and have visible water droplets. The windows are partly older wooden windows and partly skylights with metal frames.
I then bought two thermometers/hygrometers from TFA and placed them in the bedroom and kitchen. The humidity levels were between 60-70%.
I have read up online and gathered a lot of tips. We ventilate at least twice a day, usually more often, by fully opening windows for 5-10 minutes maximum, with heating off during this time. The temperature in all rooms is between 19 and 20°C (66-68°F). Laundry is not dried inside the apartment; after showering and cooking, we also ventilate thoroughly and turn on the extractor fan, as well as when the washing machine is running.
Although we notice that during ventilation, the humidity drops to around 40-45%, it rises again within minutes to at least 53% and then slowly moves toward 56-60%. In the morning, the bedroom is about 63-68%, and the kitchen 61-67% (humidity even goes higher during cooking despite ventilation).
We have moisture-absorbing granules in the kitchen and bedroom, but unfortunately, they haven’t made any improvement.
I did not experience this problem at all in my previous apartment and am currently unsure what to do. I plan to start documenting this in writing and then address it with the landlord, but I wanted to ask here first if anyone has any further tips on what I might try.
Thank you very much.
Best regards,

Baumfachmann30 Dec 2017 00:36Just google it—there are companies and hardware stores that rent devices like this. There are also tools available at hardware stores for around 15€ (about $16) that are not as precise but sufficient to detect moisture in walls. It is possible that dampness enters through hairline cracks on the exterior wall. However, the cause could also be inside, such as a water pipe or heating pipe, and you might not necessarily see any visible signs.

Baumfachmann30 Dec 2017 00:37Clarity can only be achieved by measuring all surfaces in the apartment at points spaced 50cm (20 inches) apart.
So, here in NRW, the forecast for today is 10°C (50°F) with 90% relative humidity.
That would be over 50% relative humidity at 19°C (66°F).
This is exactly what I’m getting at. Depending on the location, we don’t have the typical winter conditions of 2-3°C (36-37°F) with low relative humidity, but rather wet autumn-like weather.
