Is this black mold and who should I call?« Back to Previous Page

Based on your description, this has a high probability of being a mold colony. The location on an exterior wall is a classic indicator of a condensation issue, which is extremely common in Dubai due to the high outdoor humidity levels clashing with cold air-conditioned surfaces inside. The recent humidity would absolutely exacerbate the problem by providing the moisture necessary for mold growth.

The term "black mold" is often misused. While Stachybotrys chartarum (a toxigenic species) is black, many other common molds like Cladosporium or Aspergillus niger also appear as black spots. Only professional testing can confirm the species. Regardless of the type, any visible mold growth indicates a moisture problem that needs to be resolved and can cause allergic reactions, respiratory irritation, and damage to your property and belongings.

You should not call a regular cleaner. Improper cleaning can disturb the spores, causing them to become airborne and spread throughout your home. The first and only call you should make is to a specialized mold inspection and testing company.

A certified professional will conduct a thorough assessment to identify the moisture source (likely a thermal bridge in the wall or inadequate insulation), perform air and surface sampling to identify the contaminant species and concentration levels, and provide a detailed protocol for safe remediation. This scientific approach is crucial for a permanent solution, not just a cosmetic cover-up.
