How to safely remove black mould and check for health issues?« Back to Previous Page

We've lived in our villa in Mirdif for about five years and over the last couple of months, we’ve all had this persistent dry cough that gets worse at night. I’ve just noticed a patch of black mould starting to spread on the wall behind our wardrobe, which probably got damp from the last time we deep-cleaned the AC vents. What are the specific steps I should take right now to deal with this mould safely and check if it’s the cause of our health issues?

Good afternoon from Dubai. That is a very common yet serious issue we see in villas here, especially in areas like Mirdif. That persistent dry cough worsening at night is a classic symptom of exposure to mould mycotoxins. Here’s the immediate action plan you should follow, based on UAE best practices.

First, do not attempt to remove that mould yourself, especially if its over a square foot. Disturbing it will aerosolize the spores, potentially making the health issue much worse. Your priority is to contain the area. Isolate the room, close the AC vent in that space, and if possible, seal the area with plastic sheeting.

The next critical step is a professional inspection. This is not just about the visible patch; the hidden growth inside your AC ductwork and behind the walls is the real concern, exacerbated by our high humidity. A certified inspector will conduct a visual assessment, moisture mapping, and most importantly, air quality sampling to identify the spore types and concentration. This is vital to definitively link it to your family's health issues and to plan the remediation. All our work follows the strict guidelines of Dubai Municipality's public health and safety department.

The remediation process itself is technical: it involves setting up negative air pressure containment, using HEPA filtration scrubbers, safe removal of contaminated materials, and a thorough hygienization of the entire AC system and affected surfaces with EPA-approved fungicides. Finally, post-remediation verification testing is done to ensure the space is truly safe.

Given the health symptoms you describe, I strongly recommend you call our team for a comprehensive assessment. We can be on site quickly to handle this safely for you.
