Timing of Blower Door Test

Hello forum,

I just received an announcement email from a third party that the BD test is supposed to be carried out next week. I can't quite understand that, since we just got the screed on Thursday and will only start ventilating next week. Is that even reasonable at this stage? I mean, I don't want to press the moisture into all the cracks, especially since the interior walls are still completely in their raw state (timber frame construction) and not even plastered etc.

Thanks in advance!

The walls and roofs should also not be lined on the inside, so that the holes in the foil can be sealed if necessary

A construction-accompanying BDT should ideally be done even before the screed, because any leaks beneath floor-to-ceiling windows and at the entrance door can be better located then. It is important that the airtightness layer (vapor barrier in the roof and possibly wall) is installed and as accessible as possible.

Ok, thanks for the answers...the test went quite well. If I remember correctly, we should be below 3.0 and the measurement was 0.51...
