I have a 12 year old house that is a prefab. No basement under it (it is on cement pillars). It has been empty for 1 and 1/2 years. (I inherited it.) I recently decided to move into it. Their is a musty smell in the master bathroom. We have removed the carpet and it seem s to be coming from the floor. Who do I call to come and find out if it is mold or where the smell is coming from. My stuff is in the house but I am staying at a friends due to the smell.
