Mold from AC leak: DIY or call Dubai professional?« Back to Previous Page

Given the visible growth and strong odour you're describing, this requires a professional assessment. In Dubai's climate, that persistent humidity and condensation from an AC leak create an ideal environment for mould, and what's visible on the wall is often just a fraction of the growth behind it.

Using bleach spray from a hardware store is not recommended. Bleach is mostly water, which can feed mould roots deep in porous materials like drywall. It also fails to address the microscopic spores and can pose respiratory risks in an enclosed space without proper protective equipment. The headache you're experiencing is a common reaction to mycotoxins and volatile organic compounds released by active colonies.

For a situation involving an ongoing leak, structural materials, and health symptoms, a professional inspection is the prudent step. They will identify the full extent of the contamination, including within the wall cavity and the AC unit itself, and pinpoint the moisture source. Reputable firms in Dubai use methods aligned with IICRC standards for remediation, which involve containment, HEPA filtration, and antimicrobial treatments approved for use indoors. The final step should always be verification, often through post-remediation testing, to confirm the environment has been returned to a healthy state. For a leak in a master bedroom, ensuring it's resolved correctly is crucial for your indoor air quality.
