Mold under carpet from AC leak: urgent professional needed?« Back to Previous Page

Yes, you need a professional assessment immediately. The visible patch is a major red flag, as mold growth under carpets in Dubai's climate is often far more extensive than it appears. The concrete subfloor is porous, and the damp, dark environment created by the AC leak allows it to spread unseen.

In Dubai's high humidity, especially now, this mold will not remain a small patch for long. The constant moisture from the leak and the ambient humidity provide ideal conditions for rapid growth. You are right to be concerned about it spreading.

For a situation like this, a professional inspection is strongly advised. They will use moisture meters and thermal imaging to map the full extent of the water damage and hidden mold growth within the concrete and underlay. The priority is stopping the AC leak at its source—this is non-negotiable. No remediation will be successful if the moisture issue isn't fixed first.

While a very small, surface-level patch on a non-porous material can sometimes be addressed by a homeowner, this is not that case. The combination of a porous concrete subfloor, the likelihood of deep penetration, and the ongoing moisture source makes a DIY attempt risky and likely ineffective. Improper cleaning can aerosolize spores and spread the contamination.

A reputable mold remediation provider will isolate the area, remove the affected carpet and underlay, and use professional-grade antimicrobial treatments on the concrete to address the root of the problem. They should also provide before-and-after testing to verify the space is safe. Given the potential health risks and for the integrity of your apartment, getting a professional assessment is the necessary next step.
