How to treat mold behind wardrobe and prevent moisture?« Back to Previous Page

The damp, cold wall and recent humidity point to condensation, a very common issue in Dubai's climate where AC-cooled walls meet warm, humid air. The black spots are likely mould, and your children's coughing could be a reaction to the spores now airborne from the disturbance.

For immediate treatment, safety is critical. Wear an N95 mask and gloves. Mix a solution of 4 parts water to 1 part white vinegar—bleach is less effective on porous surfaces and can worsen respiratory irritation. Scrub the visible mould off the wall. However, this only addresses surface growth; the mould's root structure (hyphae) will remain deep within the plaster if the wall has been damp for an extended period.

Stopping the moisture is the only permanent solution. The wardrobe was trapping air, creating a cold spot for condensation to form. After cleaning, leave the wardrobe pulled slightly away from the wall to ensure constant air circulation. Consider applying an anti-condensation paint to that wall as a barrier. Check if your AC unit is correctly sized and dehumidifying properly; an overworked unit can create excessive temperature differentials.

Given the symptoms and the hidden nature of the issue, a professional inspection is strongly advised. They use moisture meters to quantify the dampness within the wall and can take an air sample to identify the mould species, which is crucial for understanding potential health risks and ensuring the remediation protocol is correct. In many cases, the wall material itself must be removed and replaced to fully resolve a persistent dampness issue of this nature.
