Remove black mold in closet myself or call professional in Dubai?« Back to Previous Page

Since the mold returned after cleaning, you have a persistent moisture issue that needs to be addressed first. In Dubai's climate, this is commonly due to condensation from an AC supply line running through the closet or a small leak in the external wall.

For a small, surface-level patch, you can attempt remediation using a dedicated fungicidal cleaner from a hardware store, not just vinegar. Wear an N95 mask and gloves. However, the key is finding and stopping the moisture source. If it's condensation on cold pipes, insulating them is essential.

If the mold returns a second time, covers more than one square meter, or you discover significant moisture within the wall, professional assessment is recommended. They can use moisture meters and borescopes to diagnose the hidden cause. Remediation for a single closet is a relatively contained job, but the final cost depends entirely on the source of the problem, which must be fixed to prevent recurrence. Always request a post-remediation verification test to confirm the space is truly clean.
