Mold is really a fast growing fungus now here is what I have done because I am allergic to it and when I find it I get a spray bottle filled with half bleach half water and spray the dickens out of it now this may sound and might very well be trivial to your problem but an attorney cost a lot of money, the previous home owners probably didn’t know it, yes, there is the house inspector but he won’t do anything in time to STOP the mold and that’s really the problem isn’t it? If you let it keep growing while you find a monitary solution your doing yourself harm. Just start spraying, call a contractor and then call your mortgage co. they actually own the house if you DIDN’T PAY CASH FOR IT DID YOU!!!!!!
