How to permanently stop black mold in my Dubai bedroom?« Back to Previous Page

The recurring mold indicates a persistent moisture source, likely from condensation due to the temperature difference between your air-conditioned room and the humid outside air in Jumeirah. This is a common issue for exterior walls in Dubai. Vinegar only removes surface growth; the root cause must be addressed.

First, identify the moisture. The most probable cause is condensation forming on the cold interior surface of that external wall. To verify, tape a small piece of aluminum foil tightly to the wall. After 24 hours, if moisture appears on the outer side of the foil, it's condensation from high indoor humidity. If moisture is underneath, it's a leak from outside, which is less common but possible.

For condensation, the solution is to lower the indoor humidity and improve air circulation. Ensure your AC is running efficiently and set to an appropriate temperature—typically between 22-24°C—to help manage humidity. Use a dehumidifier in the bedroom, especially during more humid periods. Crucially, improve airflow around that closet; leave the doors ajar and avoid pushing furniture tightly against the external wall. For a more permanent fix, consider having a professional assess if adding insulation to that specific wall is feasible to prevent the cold surface where condensation forms.

Given the health symptoms and the mold's persistence, a professional inspection is strongly recommended. They can use a moisture meter to precisely locate the problem and rule out other sources, like a hidden pipe leak. For a confirmed long-term solution, the underlying moisture issue must be resolved; otherwise, the mold will continue to return.
