Should we worry about small black mold and clean it ourselves?« Back to Previous Page

We've lived here for 2 years and just noticed a small patch of black mold in the corner of our master bedroom closet where we store our winter clothes. It's been incredibly humid the last few weeks and we've been running the AC non-stop. My wife has been waking up with a stuffy nose and a cough that goes away when she's at work. **Should we be worried about this small amount of mold, and is it safe to clean it ourselves with bleach or do we need to call a professional company here in Dubai?**

The small patch of black mold is a definite concern, especially given your wife's symptoms that improve when she's away from the home. This is a classic sign of a mold-related reaction. In Dubai's climate, where high humidity and constant AC use create condensation, even a small visible patch can indicate a larger moisture problem within the wall.

For a patch smaller than one square meter, you can clean it yourself. However, do not use bleach. It's mostly water, which can feed the mold roots inside porous materials like drywall, and the fumes are problematic in an enclosed space. Instead, use a dedicated mold remover or a solution of distilled white vinegar and water. Scrub the area, let it dry completely, and dispose of any contaminated porous items like cardboard boxes.

The critical step is identifying and stopping the moisture source. In a closet, it's often condensation from an adjacent AC duct or a cold exterior wall. If the mold returns after cleaning, the moisture issue remains unresolved. Given the symptoms and the potential for hidden growth inside the wall cavity, a professional inspection is advised. They use moisture meters and thermal cameras to find the source, which is essential for a permanent fix. For health safety and verification that the space is truly clean, post-remediation testing by an independent lab is the definitive standard.
