How to stop AC mold behind skirting board permanently?« Back to Previous Page

Based on your description, you are likely dealing with active mold growth, a common issue in Dubai due to our high ambient humidity and the constant condensation from AC units. The visible spot is only the tip of the iceberg; the moisture has almost certainly wicked into the carpet underlay, the wall cavity, and behind the skirting board, creating a perfect environment for hidden colonization.

Effective DIY treatment is difficult to achieve permanently because it requires addressing both the symptom and the source. First, you must stop the water intrusion. Identify and repair the AC drain line clog or condensation pan issue causing the leak. Until this is fixed, the problem will recur.

For the visible mold on non-porous surfaces like the skirting board, you can carefully clean with a solution of detergent and water. However, for porous materials like carpet, carpet underlay, and drywall, complete removal is often the only safe and effective solution. These materials cannot be adequately cleaned of mold roots (hyphae). Scrubbing can agitate and release spores into the air.

Given the duration of the leak, a professional inspection is strongly recommended. We use borescopes to inspect inside wall cavities and moisture meters to map the exact extent of water damage, which is almost always greater than it appears. DIY attempts often spread spores or fail to address the root cause, leading to regrowth and potential health issues.
