Mold in bedroom causing illness: who to call?« Back to Previous Page

The symptoms you describe—morning headaches and congestion that resolve when you leave—are classic indicators of a mold-related indoor air quality issue, particularly in a humid climate like Dubai where AC units are constantly battling moisture. The black, fuzzy patch behind the curtain is a visible sign, but the real concern is the hidden microbial growth inside the leaking AC unit and potentially inside the wall cavity, which is aerosolizing spores as you sleep.

In the UAE, you should first contact a licensed mold inspection and testing company, not a general handyman or AC repair service. A proper inspector will use moisture meters and thermal imaging to locate the full extent of the water damage and take air and surface samples for analysis at an accredited microbiology lab. This lab report is critical; it identifies the species (e.g., Cladosporium, Aspergillus, or Stachybotrys) and spore concentration levels, which dictates the necessary remediation protocol.

For removal, the Dubai Municipality has guidelines for contractors, but the industry is not uniformly regulated. Ensure any remediation company you hire after the inspection provides a detailed scope of work that includes containment of the affected area, HEPA filtration, and proper disposal of contaminated materials. They should also identify and fix the root cause of the moisture, which is your AC leak, to prevent recurrence. The entire process, from inspection to post-remediation verification testing, should be documented with data.
