Black mold found in kids' room, what to do first?« Back to Previous Page

First, address the immediate health concern by moving your children to a different, well-ventilated room and keeping them away from the affected area. Do not attempt to dry-scrub or vacuum the mold, as this will aerosolize the spores and can worsen their coughing.

For the mold itself, the presence on an exterior wall combined with a constant damp feeling points to a potential condensation issue, which is extremely common in Dubai due to the high outdoor humidity meeting cooled interior walls from constant AC use. The wall itself may be holding moisture.

Given that this is in your children's bedroom and health symptoms are already present, a professional inspection is strongly recommended over a DIY approach. The black patches need proper identification; what is often called "black mold" can be one of several species, and only a lab culture can confirm the type and potential risk. A reputable inspector will use a moisture meter to find the exact source of the dampness—whether it's interstitial condensation, a minor leak, or something else—which is critical to preventing its return.

For a small, surface-level patch, you can carefully clean it with a microfiber cloth and a solution of diluted detergent. However, if the mold has penetrated porous materials like drywall or the back of the dresser, those materials likely need to be removed and replaced, as mold roots deeply into them.

The most critical step is not just removal but solving the humidity source. This will involve assessing the room's ventilation, ensuring your AC unit is draining properly and not overcooling that specific wall, and potentially using a dehumidifier. Companies with their own microbiology labs can provide the testing needed to identify the species and verify that the remediation was successful through post-cleaning air or surface samples.
