AC mold in bedroom: DIY or call a pro?« Back to Previous Page

That black spotting spreading on your wall is a clear sign of a moisture issue, likely from the AC condensate leak. In Dubai's climate, with high humidity and year-round AC use, this is a common but serious problem that requires immediate attention.

For a case like yours, a professional assessment is strongly recommended. The visible mold is often just the surface issue; the leak has likely created a larger colony inside your wall cavity or AC unit itself. DIY sprays from a hardware store will only bleach the surface, missing the root cause and allowing it to return quickly. More importantly, aggressive scrubbing can aerosolize spores, potentially spreading the contamination and increasing inhalation risks.

A proper remediation process involves isolating the area, using HEPA filtration to capture spores, safely removing affected porous materials like drywall, and treating the source with specialized antimicrobials. The final, critical step is fixing the AC leak to prevent immediate recurrence.

The cost for professional assessment and treatment is variable and depends entirely on the extent of the hidden damage. For a contained area behind a wardrobe, the scope might be manageable. However, the final price is determined by the square footage of contamination, the depth of penetration into the wall, and the necessary repairs. Reputable companies in Dubai should provide a detailed assessment and quote only after a thorough inspection. Always verify they hold a valid DHA permit for mold remediation work.
