Black mold in bedroom causing illness, need removal company?« Back to Previous Page

The AC in our master bedroom has been leaking a bit, and now I’ve found black spots spreading on the wall behind the wardrobe. My husband has had a persistent cough for over a month that just won’t go away, and I’m starting to worry it’s connected. We’re in an older building in Bur Dubai. What’s the best way to get this properly tested and removed, and can anyone recommend a reliable and affordable company that actually deals with the root cause, not just a surface clean?

Black spots on a wall with a known AC leak and a persistent cough are strong indicators of a mold issue, likely linked. Dubai's high humidity and constant AC use create perfect conditions for mold growth when condensation or leaks occur.

For proper testing, a professional inspection is essential to identify the extent of the growth, including inside the wall cavity and the AC unit itself. A legitimate inspection includes moisture mapping and often air or surface sampling sent to an accredited microbiology lab to identify the specific mold type, which is crucial for health concerns.

Removal is not a surface clean. The process should involve isolating the area, removing contaminated porous materials like drywall, HEPA vacuuming, and antimicrobial treatment of the structure. The root cause—the AC leak—must be repaired by an HVAC technician to prevent immediate recurrence.

While I can't recommend specific companies, look for providers who offer a full diagnostic-to-remediation process with documented lab results and certifications like IICRC. They should provide a detailed scope of work and warranty. For a case involving health symptoms, a science-driven company with its own lab can be critical for verifying the environment is safe post-remediation.
