For a 4×4 meter room, the remediation process is not a simple cleaning task. It involves a full containment of the area with negative air pressure to prevent cross-contamination, professional-grade HEPA filtration to capture airborne spores, and the safe removal of contaminated materials like drywall and insulation. The AC system itself will likely need inspection and cleaning to prevent reoccurrence.

Costs can vary depending on the extent of the damage behind the wall, but for a proper remediation of that size, you should budget between AED 4,000 to AED 8,000. This investment is crucial for your family’s health and to protect your property’s integrity.

I strongly advise against DIY attempts, as improper handling can aerosolize the spores, significantly worsening the contamination and health risks. You need a certified professional to conduct an inspection, air quality testing, and complete remediation.
