Urgent to check bedroom mold on external wall?« Back to Previous Page

Based on your description, this situation warrants a professional inspection within the next few days, not next weekend. The presence of visible growth on an external wall, combined with a recent increase in humidity and the onset of health symptoms like a stuffy nose, are strong indicators of an active mold issue.

In Dubai, external walls, especially those facing water bodies like the marina, are highly susceptible to condensation. This occurs when the hot, humid external air meets the cooled interior surface of the wall from your year-round air conditioning, creating a perfect breeding ground for mold within the wall cavity. The black spots you see are likely just the visible tip of a larger, hidden colony.

The health symptom your husband is experiencing is a significant concern. Continuous exposure to mold spores, even from a small patch, can exacerbate allergies and respiratory issues. UAE building regulations and health guidelines emphasize addressing indoor air quality hazards promptly to protect occupant health.

I strongly recommend you contact a certified professional immediately. A proper inspection involves moisture mapping with thermal imaging and borescope cameras to assess the extent of the problem within the wall, followed by air quality testing to identify spore types and concentrations.

For a thorough assessment and remediation plan, call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com. Their certified team can provide a definitive diagnosis and a compliant solution to ensure your home is safe and healthy. Do not attempt to clean this yourself, as disturbing the colony can cause a significant release of spores.
