Should we treat black mold ourselves or call professionals?« Back to Previous Page

The black mold in your closet is likely due to the recent high humidity interacting with a cooler surface, creating condensation—a very common issue here. Given your wife's symptoms, this should be addressed promptly.

For a patch smaller than one square meter, you can attempt to clean it yourself. Wear an N95 mask and gloves. A vinegar solution can be effective for surface mold on non-porous materials like painted drywall. Scrub the area thoroughly and ensure it is completely dry afterward. However, this only addresses the visible growth, not the underlying moisture problem. You must identify and rectify the source of the dampness, which could be a small leak, capillary action from the floor, or poor ventilation.

If the mold returns quickly after cleaning, the patch is larger than one square meter, or you discover the drywall or backing is soft and damaged (indicating significant water intrusion), professional assessment is necessary. DIY methods cannot address mold growing inside wall cavities. A reputable inspector will use moisture meters and thermal cameras to find the hidden moisture source and can take samples for lab analysis to identify the species, which is crucial for understanding potential health risks and planning the correct remediation strategy. In Dubai's climate, without solving the root cause, mold will almost certainly recur.
