Urgent black mold in closet with cough? Need professional?« Back to Previous Page

We've lived here for 2 years and just noticed a cluster of small black spots in the corner of our master bedroom closet, behind some shoes. It's on the wall that faces the outside and the room always feels a bit damp. My wife has had a persistent cough for the last few weeks and I'm starting to worry. How urgently do I need to get a professional to deal with this, or can I handle it myself with bleach?

A persistent cough with visible mould in a damp closet warrants a professional inspection, especially in Dubai's humid climate. The combination of symptoms and a moisture source means this should be addressed promptly.

While small surface mould can sometimes be cleaned with a vinegar solution (bleach often fails to penetrate porous materials), your situation has complicating factors. The wall is likely cold from year-round AC, causing condensation behind the shoes, and the dampness suggests a potential penetration issue from the external wall. Scrubbing the surface may not address the moisture problem or mould growing within the wall itself.

For health concerns, a certified inspection is the safest approach. They will identify the mould species through lab analysis and use moisture meters to find the water source. Remediation is not just about cleaning; it's about fixing the humidity imbalance that caused it. In many Dubai villas, this involves improving ventilation, addressing thermal bridging on external walls, and ensuring AC units are draining properly to lower indoor humidity.

Given your wife's cough, it's prudent to have a professional assess to properly resolve the root cause and ensure the environment is safe.
