Humidity 60% Masonry damp

Well then, have fun in the moldy dump. At least you’re only damaging your own building fabric and not a landlord’s.

I don’t have the time or the colored pencils to draw it. I asked if it can be normal that it is still relatively damp. I can only ventilate and not tear down the roof. Not why it’s molding, because it isn’t, and I don’t want it to get that far in the first place.

Yes, that's what we say: it is normal if you don't ventilate regularly, but it is not good! -> that's why we recommend ventilating before you have to ask the question "...so, how do we get the moisture out?"

In our cold attic, the humidity is 70% at about 2°C. I was just upstairs and inspected the rafters etc. with a spotlight. Could not find anything unusual. Is that normal? How is it with you?

It is normal, the absolute humidity of the air is very, very dry.

Hello, we are now living in the house for the first winter.
The humidity is always around 60%, sometimes even higher.
The exterior plaster was completed last week.
Moisture is also accumulating on the roof windows.

Could it be that the masonry is still that wet?
It's a brick house without ventilation.

Regards, Patrick

Maybe a construction dryer would help as well?

Completely normal with cold roofs, we currently have 5 degrees and 67 percent.
