AC unit leak causing black mold: DIY or professional cleanup?« Back to Previous Page

What you're describing requires professional assessment, not a DIY approach. The combination of an AC leak, visible black splotches on the wall, a damp smell, and allergy symptoms strongly suggests a significant mold issue that has likely spread beyond what you can see. In Dubai's high humidity, this situation can worsen rapidly.

Vinegar or supermarket solutions are only suitable for small, surface-level mold on non-porous materials. Your wall is porous, and the moisture from the AC leak has almost certainly penetrated deep into the drywall and possibly the carpet padding, creating an extensive colony. Disturbing it incorrectly can release a large number of spores, worsening your allergy symptoms and contaminating other areas.

For a case like this, a professional inspection is necessary to determine the extent of the hidden growth inside the wall cavity and to identify the mold species. The root cause—the AC unit leak—must also be repaired first; otherwise, the mold will return immediately even after cleaning. Remediation typically involves isolating the area, removing contaminated porous materials like affected drywall and carpet, HEPA vacuuming, and antimicrobial treatment.

Given your health reaction, it's important to address this properly. Look for a provider that offers a clear diagnostic process, can explain Dubai Municipality guidelines for remediation, and provides verifiable before-and-after testing from an independent lab to confirm the space is safe.
