Absolutely get involved and be a squeaky wheel. It matters less that there is a smell and more that your daughter and others are having respiratory issues. That is significant! Do something today!
On another note, we do all we can to teach our kids everything before they turn 18 and go away to college, but we don’t get it all in. On my D’s 18th birthday, I didn’t throw her to the wolves and say “My work here is done.” I’m still available to fight like heck for her when need be. Potential mold issues are serious and I know my D wouldn’t know to fight on this one. I am not micromanaging her in her first 6 weeks of college (classes, homework, $, etc), but on this issue, I’d be making lots of calls!
