AC unit leak caused large black mold, professional needed?« Back to Previous Page

Based on the description, this is absolutely a job for a professional mold remediation company and not a DIY project. A two-meter patch of black mold resulting from a chronic AC leak is a serious contamination issue.

The black discoloration strongly suggests a Stachybotrys chartarum infestation, which is a toxigenic mold species that requires specialized protocols for safe removal. Disturbing it yourself with store-bought cleaners will aerosolize the spores, spreading the contamination to other areas of your villa and posing a significant health risk through inhalation. The damp smell confirms an active moisture source, meaning the mold is growing.

In Dubai, our remediation process for a case like this is comprehensive. First, we'd conduct a detailed inspection, including moisture mapping and air quality testing, to determine the full extent. The remediation itself involves setting up critical barriers and negative air pressure containment to isolate the affected area, preventing cross-contamination. The moldy drywall and insulation are then removed and disposed of as hazardous waste, following Dubai Municipality guidelines. The entire area is then HEPA vacuumed, abrasive-blasted, and treated with antimicrobial agents. Crucially, the root cause—the AC leak—must be identified and repaired by a certified HVAC technician to prevent immediate recurrence.

For a contamination area of that size behind a wardrobe, you should anticipate costs starting from AED 4,000 upwards, depending on the depth of the damage into the wall and the required repairs.

This is not a wait-and-see situation. For a proper assessment and quote, you should call our specialists immediately at 800-MOLDS (800-66537) or email hello@saniservice.com.
