Black mold from AC making us sick; professional cleanup needed?« Back to Previous Page

The AC in our master bedroom has been leaking for a while, and now we’ve found black and greenish fuzzy patches spreading on the wall behind the wardrobe. My husband has had a constant stuffy nose and a cough for over a month that just won’t go away. We’re in an older building in Deira and I’m starting to worry it’s the mold making him sick. Should we handle the cleanup ourselves with bleach or is it absolutely necessary to call a professional mold removal company here in Dubai?

Based on the symptoms you've described and the visible growth behind the wardrobe, it is absolutely necessary to call a professional mold remediation company. Do not attempt to clean this with bleach, as this is a serious contamination event.

The black and greenish fuzzy patches indicate a significant fungal colony, likely including toxic black mold (Stachybotrys chartarum), which is known to cause the exact respiratory symptoms your husband is experiencing—persistent cough, nasal congestion, and fatigue. The AC leakage has created a persistent moisture source, and Dubai's high humidity provides the perfect environment for this mold to thrive inside your wall cavity, which is a much larger problem than the surface growth you can see.

Bleach is ineffective on porous materials like drywall and can actually aggravate the situation by releasing more spores into the air without addressing the root cause. DIY attempts will not solve the hidden moisture problem or safely contain the spores during removal, leading to cross-contamination and recurring health issues.

In Dubai, professional remediation is not just recommended; it's governed by strict hygiene and health regulations (such as those from Dubai Municipality) to ensure the complete removal of biological contaminants and the restoration of healthy indoor air quality. Our process involves:
1. Containment of the area with negative air pressure to prevent spore spread.
2. Professional-grade HEPA filtration to scrub the air.
3. Safe removal and disposal of contaminated porous materials (like the affected wall section).
4. Application of EPA-approved antimicrobial agents.
5. Identifying and rectifying the source of the moisture—in this case, the AC leak, which must be repaired by an HVAC specialist to prevent recurrence.

For a proper inspection and a certified remediation plan, I strongly advise you to contact our team at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com.
