Hi Bill,
Sorry to hear your problem.

Don't fool around with mold! I bought a house we knew it was a fixer upper, but it was in a neighborhood my wife & I really liked and got it for a song. I found out later from a neighbor had been flooded at one time from a plumbing issue.
I had been having sinus problems since we moved in. I'd wake up in the morning with awful sinus headaches.

I sleep right next to the master bath, which my wife had trouble getting the mold in the grout to clean up, so we finally gutted that bath room. We ended up having to tear out the sheet rock walls, it was filled with black mold, and the other bath adjacent to it had to be done as well. I feel a lot better since we killed all the mold.
So I guess I'm saying, get it dry as fast as possible & don't spare the bleach!!

Hope it all goes smoothly,
EricV
