You may want to have the mold checked out and see if you are still under a home warranty. Note that many insurance companies have written damage from mold out of their policies and even limited greatly (such as to $5k) damage from flood/water resulting in mold problems. Mold can greatly damage your health and few doctors even know anything about it. EPA has good info on mold. One idea is to leave your bathroom vent fan running. Also, maybe you can Killz it if it is a paintable wall? Any luck?
