How to remove black mold from closet in humid Dubai?« Back to Previous Page

Black mould in a closet on an exterior wall is a common issue in Dubai due to the high humidity and temperature differential between the air-conditioned interior and the hot outside air, which causes condensation.

For a small patch (under one square meter), you can clean it yourself. Wear an N95 mask, gloves, and eye protection. Mix a solution of one part distilled white vinegar to four parts water or a diluted bleach solution (follow product instructions carefully). Scrub the area thoroughly, then dry it completely with a fan. All affected porous materials like cardboard boxes must be discarded. Wash any clothes in the closet on a hot cycle, as mould spores will have contaminated them.

You should call a professional if the mould covers a larger area, if it returns after cleaning, or if you notice a persistent musty smell. This indicates a deeper moisture issue within the wall or poor insulation that needs expert diagnosis. Professionals use moisture meters and thermal imaging to find the hidden source of the dampness. Remediation involves containment to prevent spore spread throughout your home and industrial-grade air scrubbers. For verifiable results, a company with its own microbiology lab can provide before-and-after testing to confirm the mould species and that the spore count in the air has returned to safe levels.
