Black mold in closet - call building management first?« Back to Previous Page

Start with building management. In Dubai, the external wall is likely part of the common property, making the building owner responsible for investigating and fixing the source of the moisture. The recent humidity suggests condensation from a cold bridge or a potential leak from outside, both structural issues they must address.

Do not attempt to clean it yourself. Disturbing the mold can release spores throughout your home. A professional inspection is needed to identify the mold species and the exact moisture source. The humidity here means it will return unless the root cause is fixed.

While you wait for management, improve air circulation in the closet. Leave the door open and consider a small dehumidifier or desiccant bags to lower local humidity levels, which can help slow its spread temporarily.

For proper remediation, you need a company that uses containment procedures and HEPA filtration to prevent cross-contamination, followed by antimicrobial treatment. The key is their diagnostic process—they should use moisture meters and thermal imaging to find the hidden source, not just wipe the surface.
