Because of the possible health risks associated with mold in general, I would HIGHLY recommend that you contact a mold abatement contractor within your area specializing in the removal and treatment of mold.
This contractor will also provide testing of the mold and will follow proper protocol to remove and treat it with the foremost concern for the safety of your family.
