Does no one here have any money left over?

= Donation

I’m building myself and know these problems.

Good luck!

Oh dear, can the "minimally invasive" issue be fixed – you are already living in the house.
Fingers crossed that the contractor acknowledges the fault and resolves it.

I would say “luck in misfortune.” The water ingress, occurring beneath the vapor barrier, ended up in the screed layer. Although it is an anhydrite screed and therefore difficult to dissolve in water, I still suspect that, since no water penetrated for a long time, it is likely just some moisture rather than actual wetness. A good sign is that some water drained away immediately. The delay from the start of the rain until the water penetration probably resulted from water backing up at the window frame and only passing through once a certain level was reached. After the rain, the area likely dried out again, and the water accumulation happened again only during the next rainfall.

Some of you may remember that all the lift-and-slide doors were delivered at the wrong height (too low). We accepted and installed the three lift-and-slide doors for the children’s rooms in the basement level despite the incorrect height. The issue was not found there. The problem started with the four newly delivered lift-and-slide doors. Again, it was lucky in a way that we took the basement windows despite the flaw (without any price reduction, mercifully), because otherwise we would not have had the option of water drainage through lamp drilling. I knew this karma would pay off.

Our next step is to contact the window manufacturer.

Thank you for your sympathy—we were (and still are) devastated! However, it seems we will get away with just a minor setback.

I believe that the whole family’s involvement in building the house has, despite all the flaws that are probably standard today, placed it under a lucky star.

You’re saying something true and beautiful, dear Elefant! And I/we are incredibly proud of it! Especially the summer phase (terraces) was really something special!
