How to permanently treat mold in a Dubai villa closet?« Back to Previous Page

The black spots in your son's closet are a classic Dubai issue, caused by condensation forming on the cooler wall surface behind it. The year-round AC creates a temperature differential with the humid outdoor air, allowing mold to grow on the dust and organic material present.

For a permanent fix, you must address both the moisture source and the existing growth. Start by moving everything out of the closet and cleaning the visible mold with a solution of detergent and water. Avoid bleach, as it only removes the colour and can exacerbate moisture issues.

The critical step is to eliminate the condensation. This often requires improving insulation on that external wall or ensuring your AC is not set so cold that it excessively chills the wall surface. Increasing air circulation behind the closet by leaving a small gap can also help significantly.

Given your son's allergies and the fact it's spreading, a professional inspection is recommended to identify the specific mold type and its root cause. In Dubai, reputable remediation companies follow international guidelines like the IICRC S520. They will use tools like moisture meters and thermal cameras to pinpoint the problem and should provide a post-remediation verification report from an independent lab to confirm the space is truly clean and the spore count has been returned to a normal level. This is the only way to be certain the treatment is permanent and your indoor air is safe.
