How to treat black mold in closet and prevent recurrence?« Back to Previous Page

Black mold in closets on exterior walls is common in Dubai's older buildings due to high humidity and temperature differences causing condensation. Your symptoms are a typical reaction to mold spores.

For professional treatment, start with a certified mold inspection to identify the moisture source and extent. In Dubai, remediation should follow standards like the IICRC S520. The process involves containment with negative air pressure, HEPA vacuuming of all surfaces, and antimicrobial treatment of the affected area. All porous materials like damaged drywall or insulation must be removed and disposed of.

Preventing recurrence requires addressing the root cause. The exterior wall likely has a thermal bridge, where cool indoor air meets warm, humid outdoor air, creating condensation. A professional can improve insulation or install a vapor barrier. Maintain closet humidity below 50% with a small dehumidifier or silica gel desorbent bags. Ensure the room's AC is functioning properly and that the closet door is left ajar occasionally for air circulation. In many Jumeirah villas, this is a persistent issue that requires a permanent moisture control solution, not just a surface clean.
