Black mold in closet: who to call and health risk?« Back to Previous Page

Black mould in a closet is a common issue in Dubai due to high humidity and the temperature differential between air-conditioned rooms and warm exterior walls, which causes condensation. The strong musty smell indicates active growth, which can cause nasal congestion, throat irritation, and worsen allergies or asthma, especially while sleeping.

For a proper fix, you need a company that specializes in mould remediation, not just general cleaning. Look for a provider with a certified indoor environmental professional (CIEC) on staff and their own microbiology lab. This is crucial because they should test to identify the mould species and, more importantly, provide a post-remediation verification (PRV) test to confirm it's gone—this is the standard for a permanent solution.

In the meantime, reduce humidity in the room by running a dehumidifier or your AC continuously on a dry mode. Keep the closet doors open to improve air circulation. Do not attempt to scrub it yourself, as this can aerosolize spores and worsen the problem. A professional inspection is recommended to assess the extent, as mould behind the drywall is a possibility with condensation issues.
