Urgent: Black mold in bedroom, need professional or DIY?« Back to Previous Page

Black mold in a bedroom closet on an exterior wall is a common issue in Dubai due to the high humidity and temperature differentials causing condensation. Your husband's increased sneezing is a legitimate concern, as this type of mold can irritate respiratory systems.

Given its location on an exterior wall, this is likely a condensation issue, not a leak. You can clean a small patch (under one square foot) yourself this weekend using a solution of diluted white vinegar or a dedicated mold remover, wearing an N95 mask and gloves. However, this only addresses the surface growth, not the moisture source.

For a lasting solution, a professional assessment is recommended. They can identify the root cause—often insufficient insulation in the building envelope—and verify the mold type. In many JVC buildings, this requires a thermal imaging scan to find the condensation point. DIY cleaning is a temporary measure; without addressing the underlying cause, the mold will almost certainly return. If the patch is larger than a square foot or you see it returning quickly after cleaning, seek a professional inspection.
