Black mold behind bed: dangerous and how to clean?« Back to Previous Page

Black mold exposure, especially during sleep, can absolutely cause persistent coughing and respiratory irritation in children. The constant proximity means they're inhaling high concentrations of mold spores and microbial volatile organic compounds (mVOCs) all night. The risk is higher for children and those with asthma or allergies.

In Dubai's climate, this scenario is common. High humidity and year-round AC use lead to condensation, and even a small, slow leak inside a wall can create a major hidden mold colony. The first step is to stop the exposure. Move the children to another room immediately.

Do not attempt to clean this yourself. Disturbing a large patch releases a massive cloud of spores throughout your apartment. Professional remediation is required for a colony of this size. The fastest way is to contact a certified mold remediation company that follows IICRC S520 standards, which is the industry standard for professional mold removal.

They should start with containment—sealing off the area with plastic sheeting and using negative air pressure with HEPA filtration to prevent cross-contamination. The moldy section of drywall will likely need to be removed and discarded. All surfaces will then be HEPA vacuumed and professionally cleaned.

After remediation, insist on verification. The area must be tested to confirm spore counts have returned to normal indoor levels. This is a non-negotiable step; a reputable company will do this, often using a third-party lab for impartial results. They must also identify and fix the source of the moisture—in this case, the AC leak—to prevent it from returning.
