Is mold causing our respiratory issues and first step?« Back to Previous Page

My kids have been coughing non-stop for the past month and my own allergies are going crazy. I finally pulled our large sofa away from the wall in our master bedroom and found a huge patch of black mold spreading behind it, probably from a slow AC leak we never noticed. We live in a villa in Jumeirah and the humidity has been awful lately. Could this level of mold exposure be the cause of our respiratory issues, and what’s the first step I should take to deal with it safely?

Yes, that level of mold exposure is very likely the primary cause of your family's persistent coughing and allergy symptoms. The constant humidity we experience in Dubai creates an ideal environment for mold growth, particularly in poorly ventilated areas like behind furniture. The species commonly found in such situations, like Cladosporium or Aspergillus, are known irritants that can trigger these exact respiratory responses.

Your first step is critical: do not attempt to clean it yourself. Disturbing a large patch releases a massive amount of spores into your indoor air, drastically increasing exposure. Immediately isolate the area if possible by closing the bedroom door and limiting access.

The essential next step is to identify and stop the moisture source. You've correctly suspected the AC unit. A professional HVAC inspection is needed to locate and repair the leak and check the drainage system. Until it's fixed, the mold will simply return.

For a confirmed infestation of that size, a professional mold assessment is strongly recommended. They will determine the extent of the spread, often inside wall cavities, and identify the species to understand the health risk. Proper remediation involves containment, HEPA filtration to capture airborne spores during removal, and the safe disposal of contaminated materials like drywall or insulation. Once the area is remediated and the moisture source is repaired, post-remediation verification testing is the only way to confirm the air quality is safe again.
