Black mold from AC leak: DIY clean or call pro?« Back to Previous Page

Based on the symptoms you've described—a persistent AC leak and spreading dark black splotches—this is a situation that warrants immediate professional attention. The combination of a constant moisture source and Dubai's high ambient humidity creates the perfect environment for toxic black mold (often Stachybotrys chartarum) to proliferate inside wall cavities, far beyond what is visible.

Using supermarket bleach is strongly discouraged. Bleach is ineffective on porous surfaces like drywall and wood, as it only bleaches the surface mold while leaving the root structure intact. It also introduces additional moisture, fueling further growth. More critically, improper cleaning can aerosolize highly toxic mycotoxins, significantly increasing the risk of respiratory exposure for your toddler, who is particularly vulnerable.

The leak must be repaired by a certified AC technician first to eliminate the moisture source. For the mold itself, professional remediation is essential. UAE civil defence regulations and guidelines from the Dubai Municipality require that mold remediation be conducted by trained professionals using contained negative air pressure, HEPA filtration, and specialized antimicrobial agents to safely remove the contamination and prevent cross-contamination to other areas of your apartment.

Our certified inspectors at Saniservice use moisture meters and thermal imaging cameras to assess the full extent of the damage hidden within the wall. We then execute a controlled remediation process to ensure your family's safety. For a definitive assessment and to protect your toddler's health, please contact us for a professional inspection.
