Is black mold in our closet causing health issues?« Back to Previous Page

Based on the details you've provided, the situation warrants a professional inspection. The black spots in your master bedroom closet, located on an exterior wall in a villa in Al Barsha, are a significant red flag. The exterior walls of villas in Dubai are often subject to thermal bridging, where the intense outdoor heat meets the cooled interior air from your AC, leading to condensation within the wall cavity. This hidden moisture is a primary catalyst for mold growth that you only see a small part of.

Your husband's stuffy nose is a common physiological response to mold exposure, specifically to microbial volatile organic compounds (mVOCs) and spores. While small surface growth can sometimes be addressed with a hydrogen peroxide solution (avoid bleach as it does not kill the root and vinegar is often ineffective on porous surfaces), your description suggests a potential hidden infestation within the wall. DIY methods will only address the visible cosmetic issue, not the root cause of the moisture or the hidden fungal biomass.

The UAE's humid climate, combined with year-round AC use, creates perfect conditions for such issues. A certified professional will conduct a thorough inspection, including moisture mapping and possible air or surface sampling, to identify the exact species and the full extent of the contamination. Remediation must follow strict protocols to contain the area and prevent cross-contamination.

I strongly recommend you contact a certified mold inspection and remediation company like Saniservice. Their experts can accurately diagnose the problem and implement a solution that addresses both the visible growth and the underlying moisture issue.
