How to remove small black mold in Dubai apartment?« Back to Previous Page

Based on your description, this is a classic case of condensation-induced mold growth, very common in Dubai due to the high ambient humidity and constant air conditioning creating thermal bridges on exterior walls. The wall facing JLT's marina is likely colder than the room's dew point, causing moisture to condense and feed the mold behind the boxes.

For a small patch (less than 1 square meter), you can attempt a DIY remediation. First, address the moisture source. Ensure your AC is set to a consistent temperature (22-24°C) and that the closet door is left ajar to improve air circulation. Use a moisture meter to confirm the wall is dry. For removal, wear an N95 mask and gloves. Scrub the area with a solution of detergent and water, then disinfect with a diluted bleach solution (1 part bleach to 10 parts water). Do not simply paint over it.

However, the fact it's on an exterior wall suggests a potential building envelope issue, which is the responsibility of the building management under Dubai's strata laws. The mold you see is likely just the surface manifestation of a larger colony within the wall cavity.

For a definitive assessment and to ensure it's not a systemic issue, a professional inspection is strongly recommended. We use thermal imaging to identify hidden moisture and air sampling to determine spore count and species, as some black molds can be more problematic. If the problem is extensive or recurs after cleaning, the building management should be contacted to investigate potential leaks or insulation failures.
