Black mold in closet: how to handle and who to call?« Back to Previous Page

The black, speckled spots in your closet are a classic sign of condensation-related mould growth, especially common in Dubai due to high humidity and the temperature differential between your AC-cooled room and the warm exterior wall. This dampness creates an ideal environment for mould.

For a small area (under one square meter), you can carefully clean it yourself. Wear an N95 mask and gloves. Scrub the area with a mixture of detergent and water, then thoroughly dry it. Do not use bleach, as it doesn't prevent regrowth and can damage porous surfaces. However, since the wall feels damp and the mould is on an exterior surface, the root cause is likely excess moisture from condensation or a potential hidden leak.

To effectively prevent it from returning, you must address the humidity. Improve air circulation in the closet by leaving doors ajar, using a dehumidifier, or ensuring your AC is functioning correctly to manage indoor humidity levels. Storing clothes in airtight containers can also protect them.

For identification and serious cases, a professional inspection is recommended. The term "black mould" is often misused; many dark-coloured moulds are common and not the toxigenic Stachybotrys species, which is rarer. Only a lab analysis of a sample can confirm the species and any associated health risks. Call a certified mould assessment company that uses a third-party microbiology lab to provide a detailed report on the mould type and concentration. This evidence-based approach is the only way to know the severity and plan appropriate remediation, which is crucial for households with children, allergies, or respiratory sensitivities.
