How to remove black mold in closet and check inside walls?« Back to Previous Page

The black mold in your closet is likely due to the high humidity and a possible cold bridge on that external wall, a very common issue in Dubai villas. The wall's interior surface cools from constant AC, while the outside heat and humidity cause condensation inside, creating a perfect environment for mold.

For a small patch (under one square foot), you can handle it yourself. Wear an N95 mask and gloves. Mix a solution of one part distilled white vinegar with three parts water, or use a diluted bleach solution (one cup bleach to one gallon of water). Scrub the area thoroughly, then dry it completely with a fan. Avoid just painting over it, as the mold will return.

To check inside the walls, you will need a professional inspection. The mold you see is often just the surface manifestation of a larger problem within the wall cavity. An expert will use a borescope to look inside the wall for hidden growth and a moisture meter to identify the exact source of the dampness—whether it's condensation, a tiny leak, or capillary action from the foundation.

Given Dubai's climate, the root cause is almost always excess moisture. After proper remediation, improving ventilation in the closet and using a dehumidifier can help prevent recurrence. If the area is larger than a square foot or you suspect hidden growth, a certified assessment is strongly recommended to determine the full scope and ensure it is addressed safely.
