Black mold from AC leak: DIY clean or professional in Dubai?« Back to Previous Page

Based on the situation you've described in Jumeirah Village Circle, I strongly recommend against a DIY bleach clean and advise you to seek a professional mold remediation service. The combination of an ongoing AC leak, the size of the infestation (a dinner plate is significant), and the fact it's on a wall cavity behind a wardrobe indicates a serious moisture issue that simple surface cleaning will not resolve.

The black discoloration is likely Stachybotrys chartarum or another toxigenic species, which poses confirmed health risks, particularly respiratory issues and allergic reactions. Bleach is ineffective on porous materials like drywall and plaster; it only bleaches the surface while leaving the root structure intact, allowing regrowth within weeks. More critically, improper cleaning can aerosolize harmful mycotoxins, spreading them throughout your apartment.

In Dubai's high humidity climate, exacerbated by year-round AC use, this problem will only escalate without a professional approach. We follow a strict protocol: first, identifying and stopping the moisture source (the AC leak), then containing the area to prevent cross-contamination, safely removing and disposing of contaminated porous materials (like the affected section of wall), and finally, hygienizing the area with EPA-approved antimicrobials. We also conduct post-remediation verification testing to ensure the space is safe.

For a job of this scale in Dubai, costs can vary but typically start from AED 1,500 to AED 3,500, depending on the extent of the damage behind the wall. This is a worthwhile investment to protect your health and property. For a proper inspection and quote, I recommend you call our specialists at 800-MOLDS (800-66537) or email hello@saniservice.com.
