my apartment has had numerous floods in the past in different areas of the apartment. We have noticed a couple different areas where we think there are mold growth and destroyed sheetrock. Our landlord sent the super and the super caulked new sheet rock on top of the sheet rock that we thought had mold on it, and threw out an old molding that had stuff growing on it, and replaced it with a new one. But the new one won't stick to the sheet rock because it's so deteriorated. We told the landlord that we didn't think the super was competent to deal with it, and that we are worried that there might be some kind of dangerous mold in the sheet rock. the landlord suggested that the super come by and do more work-- but we are afraid of the super messing around and disturbing it and putting our health in danger. after a lot of back and forth, the landlord sent a contractor he knows over to look at the apartment. the contractor said he saw no visible signs of mold growth. i feel very confused by this assessment. i attached a link to some photos of what we think is mold.
