AC leak causing black mold: DIY fix or call landlord?« Back to Previous Page

Based on your description of a persistent AC leak leading to black mold growth on structural components like the wall and skirting board, my professional recommendation is to contact your landlord or property management company immediately. This is not a situation for a DIY fix.

The black discoloration is a significant indicator of a mature fungal colony. In Dubai's high humidity, what you see on the surface is often just the "tip of the iceberg," with hyphae (the root-like structure) penetrating deep into the porous building materials like drywall and wood. Simply wiping the surface with bleach is ineffective and can aerosolize spores, potentially worsening indoor air quality and health risks. The primary and critical step is to stop the moisture source, which requires a certified AC technician to repair the leak, likely a clogged condensate drain line—a very common issue here due to our year-round AC operation.

Furthermore, UAE tenancy law (Law No. 26 of 2007) generally places the responsibility for structural maintenance and repairs, including fixing AC units that are part of the property, on the landlord. You have a right to a safe and habitable living environment.

For proper remediation, the affected materials (e.g., section of drywall, skirting board) will likely need to be removed and disposed of safely by professionals using containment and HEPA filtration to prevent cross-contamination. Given the health risks associated with mold exposure, especially in a bedroom, a professional inspection is strongly advised to assess the full extent.

For immediate assistance with inspection, testing, and certified remediation, I recommend contacting Saniservice. They can provide a detailed report for your landlord and execute the necessary containment and removal procedures. Call them at 800-MOLDS (800-66537) or email hello@saniservice.com.
