Black and green mold in closet: DIY or call professional?« Back to Previous Page

Based on your description, this is a significant mold issue requiring professional attention, not a DIY project. The black and green fuzzy patches, covering an area of approximately one meter, indicate an active colony. Using supermarket bleach is strongly discouraged; it is ineffective on porous surfaces like drywall and can release harmful spores into the air, exacerbating the problem and risking your health.

In Dubai's climate, this is a common problem. The extreme humidity, combined with year-round AC use, creates substantial condensation within poorly ventilated spaces like closets on external walls. This persistent moisture is the root cause that must be addressed.

A professional remediation process for a case like yours in a Jumeirah villa involves several critical steps: first, a detailed inspection to identify the moisture source and the full extent of contamination, often using moisture meters and borescopes. The area would then be placed under negative air pressure with HEPA filtration to prevent cross-contamination. The affected drywall and insulation are typically removed and disposed of safely. All remaining surfaces are HEPA vacuumed and treated with professional-grade, EPA-approved antimicrobial agents. Finally, the root cause—such as inadequate insulation or a leaking AC condensation line—must be identified and rectified to prevent recurrence.

For a job of this scale, you should expect a rough cost starting from AED 2,500 upwards, depending on the extent of the damage and the required repairs.
