Black closet mold in Dubai: DIY or professional help?« Back to Previous Page

Our master bedroom closet on the outside wall has felt damp for a while, and I’ve just pulled out a bunch of shoes and winter clothes to find a bunch of black and green fuzzy spots all over the back wall. With this humidity, it seems to be spreading fast. Is this something I can tackle myself with bleach from Ace, or do I need to call in a professional company for an assessment, and what’s the typical cost for a job like this in a Dubai apartment?

Based on your description of a persistent damp feeling, visible black and green fuzzy growth on an exterior wall, and rapid spreading, this is a serious mold infestation that requires professional assessment and remediation. The Dubai climate, with its extreme humidity and the constant use of air conditioning, creates significant condensation issues within building envelopes, particularly on cooler exterior walls. This is a classic scenario we encounter daily.

Attempting a DIY solution with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall, as it only bleaches the surface mold without addressing the root hyphae deep within. It also poses significant health risks due to fumes in an enclosed space and can exacerbate the problem by adding moisture. More critically, this indicates a persistent moisture source that must be professionally identified and rectified to prevent guaranteed regrowth.

Under UAE regulations, proper remediation involves containment to prevent cross-contamination, professional-grade HEPA filtration, and safe removal of contaminated porous materials. The cost for an inspection and remediation in a Dubai apartment closet typically ranges from AED 1,500 to AED 4,000, depending on the extent of the damage and the required repairs to the moisture source.

For a definitive assessment and a compliant, permanent solution, you must call a professional. I recommend contacting Saniservice for an immediate inspection. Their certified experts can identify the moisture source, provide a detailed scope of work, and ensure the remediation is done safely and effectively.
