What are the health risks of mold and who removes it?« Back to Previous Page

The health risks from that type of prolonged exposure are significant, especially for children. The black and green mold you describe is likely releasing mycotoxins and spores into the air you breathe all night. This directly causes the respiratory symptoms you're seeing: chronic coughing, nasal congestion, sinus pressure, and can severely worsen asthma and allergies. In children, prolonged exposure can lead to more frequent respiratory infections.

For a growth that large and established, especially behind furniture where it's been undisturbed, professional remediation is strongly advised. The size indicates a deep moisture issue within the wall cavity, probably from condensation due to the temperature difference between your air-conditioned room and the humid exterior, a very common problem in Jumeirah villas.

Do not attempt to remove it yourself. Disturbing it will aerosolize a massive amount of spores throughout your home. The best service for a job this size is a certified mold remediation company that follows IICRC standards. They will use engineering controls like negative air machines to contain the spores, safely remove the contaminated materials, and most importantly, identify and fix the underlying moisture source to prevent it from returning. Look for a provider that conducts third-party, independent post-remediation verification testing to confirm the air quality is safe before they consider the job complete. This is the only way to be certain the problem is resolved.
