Hello everyone,
We are currently working with a prefab house supplier to realize our dream home. We have noticed some mold forming in certain areas on the upper floor and would like to get your opinion on whether this is normal and what the recommended course of action should be.
The screed was poured just over two weeks ago, and the underfloor heating has been running for about one week now. We are ventilating twice daily, as we were instructed to do.
I have already reported this to the site manager, who plans to remove the mold next week. I assume he intends to simply wipe it off.
Best regards,
Tobi

Mold and any type of fungus basically need moisture to grow... Even if a few beams or panels show slight traces of mold, it will most likely disappear over time because the moisture will eventually be gone... At least that’s my opinion. But we didn’t have any mold either, despite 20cm (8 inches) of snow inside the house on the day it was placed.

I have no experience with wood framing and am glad to build with solid construction when I see something like this. Is that really normal? Are you really that naive to think this only happens with wood?
Honestly, this is definitely not normal. Not even in timber frame construction. Our timber frame house never had any mold issues, neither before nor after the screed was applied. By the way, airing out only twice a day during the screed’s drying and heating phase is clearly not enough. You need to cross-ventilate 4–5 times for 15 minutes each to really get the moisture out.
Yes, mold needs moisture and nutrients to survive, but it doesn’t just appear overnight. So either there was already mold in the factory, or you have had high humidity in the house unnoticed for a longer time.

As part of my research on prefab houses, I read several articles about construction in rainy conditions. If you search for this topic online, the first result is a very detailed presentation by a building expert. It’s detailed in the sense that there are many pictures that can be quite alarming. I’m not sure how to interpret this information from a technical perspective. But if you are uncertain, it’s a good idea to have a building inspector or building biologist take a look. Considering the total investment, the cost of an expert’s assessment is minimal.
