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

That black mold in your closet is a classic Dubai issue, caused by high humidity interacting with cooler wall surfaces, often from an adjacent AC unit or external wall. The rapid spread confirms there's an ongoing moisture source.

For a small area (under one square meter), you can attempt DIY. Move all clothing out immediately. Wear an N95 mask, gloves, and goggles. Scrub the area with a microfiber cloth and a solution of white vinegar or a dedicated mold remover. Avoid bleach; it only removes the colour, not the root structure. Let the area dry completely, then monitor it. However, DIY often fails long-term because it doesn't address the hidden moisture source enabling the growth.

Given it's behind items and spreading, a professional inspection is strongly recommended. The visible spots are likely just the surface manifestation; the hyphae (root system) can penetrate deep into the gypsum board. Professionals use moisture meters and thermal imaging to find the condensation source—often a leaking AC drain line, insufficient insulation on an external wall, or poor ventilation.

In Dubai, remediation companies should follow standards like the IICRC S520. Proper remediation involves isolating the area, HEPA vacuuming, and often removing and replacing the affected drywall if infiltration is deep. The critical step is solving the moisture problem first; otherwise, it will return. A company with its own microbiology lab can provide a species identification report, which is valuable for understanding health risks and confirming cleanup effectiveness. For a recurring problem in a bedroom, this diagnostic approach is the most effective way to ensure it's gone for good.
