How to handle black mold in Dubai hom myself?« Back to Previous Page

For a small patch (under one square foot) on a non-porous surface like painted drywall, you can handle this yourself. Dubai's high humidity, especially in summer, and the constant temperature shift between AC-cooled interiors and hot exteriors creates perfect conditions for condensation and mold in closets or behind furniture on external walls.

First, move all items out of the closet. Mix a solution of one part white vinegar to three parts water or a diluted bleach solution (wear gloves and ensure good ventilation). Scrub the affected area thoroughly. After cleaning, let the wall dry completely. Use a fan or dehumidifier to speed up the process; this is critical as moisture left behind will cause it to return.

However, since you mentioned this is on an external wall and appeared behind stored items, a professional inspection is strongly recommended. The mold you see is often just the surface manifestation of a larger problem. The root cause could be a tiny crack in the external wall allowing moisture ingress, a leak from an internal pipe, or severe condensation within the wall cavity itself. DIY cleaning addresses the symptom, not the source.

In Dubai, proper remediation for anything beyond a trivial spot involves identifying and rectifying the moisture source, isolating the area to prevent spore spread, removing contaminated materials if necessary, and verifying with post-remediation testing. A science-driven company uses moisture meters and thermal imaging to find the hidden leak and microbiological lab testing to confirm the mold type and that it has been effectively removed. For a closet on an external wall, this is likely a more serious case that requires a professional assessment.
