How to permanently fix AC mold and moisture in closet?« Back to Previous Page

The issue you're describing is a classic case of localized mold growth driven by an unresolved AC condensate leak, a common problem in Dubai due to our high humidity and year-round reliance on air conditioning. The serviced unit may be functioning, but the underlying moisture intrusion point has not been addressed.

Permanent remediation is a multi-step technical process. First, the moisture source must be eliminated. This requires a certified HVAC technician to inspect the condensate drain pan, drain line, and insulation for blockages, cracks, or improper slope, which can cause water to leak inside the wall cavity. Simply servicing the unit is often insufficient.

For the mold itself, surface cleaning with bleach is ineffective and can exacerbate the problem by adding moisture. The affected area must be isolated to prevent spore dispersal. The porous wall material (drywall/plaster) is likely compromised. Professional remediation involves the careful removal and safe disposal of this contaminated material. The underlying wall cavity must then be HEPA-vacuumed and treated with an EPA-approved antimicrobial agent to eliminate hidden hyphae (root structures).

Finally, the area must be thoroughly dried using professional-grade air movers and dehumidifiers to achieve a moisture content reading below 15%, ensuring the environment is incapable of supporting regrowth. The wall is then reconstructed with mold-resistant drywall.

Given the persistent musty smell, the mold has likely penetrated beyond the visible surface. This requires expert assessment with moisture meters and thermal imaging cameras to determine the full extent. We strongly recommend a professional inspection. Our certified team at Saniservice specializes in this exact scenario, following Dubai Municipality guidelines for safe and effective mold removal.
