Is AC leak causing black mold and health issues?« Back to Previous Page

Based on your description, this is a classic and unfortunately very common scenario in Dubai apartments. The black spots are almost certainly Stachybotrys chartarum, commonly known as toxic black mold, which thrives on the constant moisture from an AC condensate leak. The cellulose in your drywall provides the perfect food source.

The health issues you're describing – the sinus headaches, congestion, and the noticeable relief when you leave the apartment – are textbook symptoms of mold exposure. This is a serious indoor air quality issue that absolutely should not be painted over, as that will only temporarily hide the problem while the mold continues to grow unseen, potentially spreading into the wall cavity.

Under UAE tenancy law, specifically Law No. (26) of 2007, your landlord is legally obligated to provide a habitable premises and is responsible for all major maintenance, including structural issues and AC system repairs. A persistent water leak and resulting biological growth falls squarely under this obligation.

To get this resolved properly, you need to do two things:

1. Formally notify your landlord/property management company in writing (email is best) about the AC leak and the visible mold growth. Clearly state the adverse health effects it is causing. This creates a paper trail.
2. Strongly recommend a professional inspection. A certified mold inspector can conduct air and surface sampling to identify the exact species and concentration, providing a scientific report that validates your claims. This report is invaluable for compelling the landlord to undertake proper remediation, which involves fixing the leak, containing the area, safely removing the contaminated materials, and performing antimicrobial treatment.

Don't just get a handyman; this requires a professional environmental solution. For a proper assessment and to get the evidence you need, you should call our team at 800-MOLDS or email us at hello@saniservice.com. We can provide a detailed report for your landlord.
