AC leak causing black spots: DIY fix or call a pro?« Back to Previous Page

Given the AC leak and visible black spots on your carpet in Jumeirah, a professional inspection is strongly recommended. What you see on the surface is often a small indicator of a larger problem. In Dubai's climate, with high humidity and constant AC use, moisture can quickly wick into the wall structure and insulation behind the carpet, creating an ideal environment for hidden mould growth that DIY methods cannot address.

While a small, surface-only spot on a non-porous material can sometimes be addressed with careful cleaning, your situation involves a porous carpet and a persistent water source. Using bleach is not advised; it is ineffective on porous materials as it does not kill the roots and its high water content can actually feed the mould growth further. More importantly, it does not address the contamination that has likely spread into the backing and subfloor.

The AC leak itself must be repaired first; otherwise, the problem will recur. A proper inspection involves using moisture meters and thermal imaging cameras to assess the extent of water damage within the wall cavity, which is not possible without specialized equipment. For a verified resolution, remediation should include removing and properly disposing of the affected carpet section and padding, treating the subfloor, and ensuring the area is completely dry before any reconstruction. This process confirms the issue is resolved at its source, which is critical for indoor air quality in a sealed apartment environment.
