How to treat and prevent black mold behind wardrobe?« Back to Previous Page

My kids have been coughing and I suspect it's because of the black spots I just found behind the wardrobe in our master bedroom. We've lived here for 2 years and just noticed this, and the room always feels more humid than the rest of our apartment in Downtown Dubai. What's the best way to treat this ourselves and what can I do to stop it from coming back for good?

Based on your description, you are likely dealing with Cladosporium or possibly Stachybotrys (toxic black mold), which is a serious health concern, especially for children. The persistent humidity in your Downtown Dubai apartment, combined with reduced airflow behind the wardrobe, creates a perfect microenvironment for mold growth, a common issue here due to our high ambient humidity and constant air conditioning use leading to condensation.

For a small, localized patch (less than 1 square meter), you can attempt to treat it yourself. However, due to the health symptoms present, I strongly advise against DIY and recommend a professional inspection. If you proceed, safety is critical: wear an N95 mask, nitrile gloves, and safety goggles. Isolate the area by sealing the door with plastic sheeting. Carefully remove the wardrobe to assess the full extent. Clean the affected wall with a HEPA vacuum to capture spores, then scrub with a solution of detergent and water. After drying completely, disinfect with a solution of 1 part white vinegar to 4 parts water; avoid bleach as it does not kill the roots and can worsen airborne spore release.

To prevent recurrence, you must control the humidity. This is a core challenge in the UAE. Ensure your AC unit is serviced and draining correctly; it is your primary dehumidifier. Improve air circulation behind furniture by leaving a 2-inch gap from the wall. Use a dedicated dehumidifier in the bedroom, especially during the more humid winter months. Consider applying a mold-resistant primer and paint to the wall after remediation.

Given the coughing symptoms and the hidden nature of mold growth, a professional assessment is crucial. We use thermal imaging and moisture meters to identify the exact moisture source and air sampling to determine the spore count and species, which is vital for health reasons. Our remediation process follows strict Dubai Municipality guidelines for occupant safety and effective removal.
