lright, the architect and his pal are gone, so here is the rest. After the kip lecture he said he thought we were just getting regular moisture in the room and not letting it back out, and he had his hand twitching over his "how to air out your apartment chart" like he was about to whip it out and show us how to care for our ever-so-fragile German apartment, but he decided to do a couple more moisture readings first. And, it turns out that although most of the room is dry enough, the corner where the mold was, right next to the floor, is WAY moister than the rest of the room. So, he decided he wasn't going to turn around and blame it all on us after all, but that maybe the heat is leaking water into the wall/floor or maybe the wall needs to be torn out (!?). Well, hopefully the wall won't need to be torn out, but we'll find out more soon.
In the meanwhile, he wants us to run the heat in the bedroom all the time and open both our windows (haha, we have two in the whole apartment) wide open four times a day. He didn't specify how long. Having the heat on is going to hurt because we use it very sparingly and never in the bedroom - I might have to start sleeping in the living room, because I sleep best in winter because the bedroom is nice and cool and conducive to the big blanket piles I love. But, at least we are on the road to having it figured out after months of no response! YAY!
