ᐅ Is Mold Growth Normal During the Shell Construction Phase?

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

No, we didn’t have that!

I have to mention that the house had to be assembled over two days because one of the three trucks broke down, and on the second day of assembly it was raining heavily.

This is nothing unusual. Especially during the heating phase of the screed, the high moisture levels can lead to mold growth.

I have no experience with timber frame construction and am glad to build solid when I see things like this. Is this really normal?

@Mycraft and is wiping away enough to resolve this? We were already aware in advance that some minor mold growth could occur due to the extreme humidity, but the extent it has reached is causing us some concern.
