Need mold removal company for dangerous black mold?« Back to Previous Page

Black spots spreading from an AC leak are almost certainly mould, and your husband's symptoms are a common reaction to the spores it releases. Dubai's high humidity and constant AC use create the perfect damp environment for it to thrive.

For this scenario, you need a company that does both inspection and remediation. The wall behind the wardrobe is just the visible part; the mould likely extends inside the wall cavity and within the AC unit itself. A proper remediation company will first conduct air and surface sampling to identify the species and spore count, which determines the containment and removal protocol. They should use a certified third-party lab for analysis—this is crucial for verifying the results, not just using in-house equipment.

Look for a provider certified by organisations like the IICRC (Institute of Inspection, Cleaning and Restoration Certification). The process should involve isolating the area with physical barriers, using HEPA air scrubbers, removing contaminated materials like drywall, and thoroughly HEPA-vacuuming and wiping all surfaces. Simply spraying a biocide is not sufficient.

After remediation, they must perform clearance testing to confirm spore levels have returned to normal. For a leak that's been ongoing for months, this is not a DIY job due to the high risk of cross-contamination. Request a comprehensive assessment that includes the AC unit, the affected wall, and the indoor air quality.
