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

Based on the symptoms you've described—a persistent AC leak leading to visible black mold growth on the wall and belongings, with a high likelihood of hidden growth inside the wall cavity—this is unequivocally a job for a professional mold remediation company. DIY cleaning with bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall and wood, as it only bleaches the surface mold while leaving the roots intact. More critically, it does not address the moisture source or any hidden contamination.

In the UAE's humid climate, AC condensate leaks are a primary cause of indoor mold. The constant high humidity, combined with condensation from the leaking unit, creates an ideal environment for rapid mold proliferation. Disturbing the mold yourself by cleaning can aerosolize highly concentrated spores, potentially spreading the contamination to other areas of your villa and posing a significant health risk.

A certified professional will follow a strict protocol: first, identifying and rectifying the moisture source (the AC leak). Then, they will implement engineering controls, such as setting up negative air pressure containment to prevent cross-contamination, before safely removing and disposing of all affected porous materials (drywall, insulation, damaged shoes). All remaining surfaces will be meticulously cleaned with EPA-approved biocides and sealed. A post-remediation verification test is crucial to confirm the spore count has returned to acceptable levels.

For a situation like this in a villa, costs can vary based on the extent of the damage but typically range from AED 2,500 to AED 7,000+ for proper remediation, including moisture mapping, containment, removal, and final verification.

Given the potential for hidden damage and health implications, I recommend an immediate professional inspection. Contact Saniservice for a comprehensive assessment and quote.
