AC leak caused black mold: urgent professional help needed?« Back to Previous Page

That fuzzy black growth is almost certainly mold, and your wife's allergy flare-up is a common symptom of the spores it's releasing. Given Dubai's high humidity and the constant condensation from your AC, this situation requires immediate attention.

For a leak that's been active for weeks and visible growth on porous drywall, a DIY approach is not recommended. Surface cleaning with bleach or vinegar only addresses the visible tip; the hyphae (roots) penetrate deep into the wall. Disturbing it without proper containment will aerosolize a high concentration of spores throughout your bedroom, severely aggravating allergies.

In the UAE, the correct protocol involves a professional assessment. A certified inspector can determine the extent of the damage behind the wardrobe and identify the species, as some types common in AC systems are more problematic than others. Remediation then requires physically removing the contaminated section of drywall/insulation under containment, using HEPA filtration to capture spores, and addressing the moisture source—in this case, repairing the AC leak. Without fixing the leak, the mold will return quickly.

For your family's health and to prevent structural damage, it's best to get a professional inspection. Look for a provider that offers documented before-and-after testing to verify the airborne spore count has been returned to a safe, ambient level.
