These pictures were taken upon move in to my new apartment. I am convinced that this is mold while the management company is claiming that it is mildew. Please help in identifying what is within my cabinet. I have already alerted the maintenance staff and the remediation consisted of removing a 3'x3' section of drywall and surface removal and paint of the affected area in the pictures. Are these processes adequate for remediation? I ask due to the fact my girlfriend works at the major medical center here in Houston and is constantly around patients. Thank you for your help in advance!
