How to treat and prevent mold in a humid apartment?« Back to Previous Page

Based on your description, this is a classic case of mold growth exacerbated by the Dubai climate. The location on an external wall, combined with year-round air conditioning, creates a significant temperature differential. This leads to condensation forming on the cooler interior wall surface, especially behind furniture like a wardrobe where air circulation is restricted. The trapped moisture and organic material (e.g., dust, cellulose in drywall) create an ideal environment for mold.

The black spots are likely Cladosporium or Stachybotrys (black mold), which are common in such scenarios and can be the cause of the respiratory symptoms your children are experiencing. Immediate action is required.

For treatment, do not attempt to clean it with bleach, as this can exacerbate spore release and does not address the root cause. The affected section of drywall is likely compromised and may need to be carefully removed and replaced by a professional remediation team to prevent the spread of spores throughout the apartment.

Prevention is absolutely critical and must address the humidity source:
1. Improve Air Circulation: Move furniture at least 6 inches away from external walls. Use dehumidifiers, especially during the more humid winter months.
2. Control Condensation: Ensure your AC unit is correctly sized and maintained. Consider having a professional assess if adding a fresh air ventilation system or an HRV/ERV unit is feasible to manage humidity levels without overcooling.
3. Hygienization: After the source is removed, the entire area should be professionally cleaned and treated with an EPA-approved antimicrobial solution to eliminate residual spores.

Given the health symptoms and the extent of growth (inside a wall cavity), a professional inspection is strongly recommended. Our certified inspectors at Saniservice use thermal imaging cameras to identify the exact moisture source and extent of the problem, and our remediation protocols are fully compliant with Dubai Municipality's strict health and environmental standards. We can provide a definitive solution to treat the current infestation and implement measures to prevent its return.
