AC mold causing headaches: DIY or professional in Dubai?« Back to Previous Page

The black spots and symptoms strongly suggest a mould issue, which is common here due to high humidity and constant AC use causing condensation. Your headaches and congestion are typical reactions to mould exposure. For a leak that has persisted for weeks and visible growth, a DIY approach is not recommended. Bleach only removes surface discolouration on non-porous materials; it cannot penetrate drywall to kill the root system, and the moisture problem from the leak is still active.

You need a professional assessment. In Dubai, this level of contamination, especially with health symptoms, requires identifying the source of the moisture (the AC leak) and properly remediating the affected wall, which likely involves controlled removal. Reputable companies will use moisture meters and thermal cameras to find the full extent of the damage hidden behind the wall. The cost for a single room is variable and depends entirely on the scope of work required to fix the leak and remove the contaminated materials. You should request an on-site inspection for an accurate assessment and a detailed scope of work that includes fixing the primary water source.
