Found black mold under my AC leak; DIY or hire pro?« Back to Previous Page

The size and location of this mold growth require a professional remediation company. In Dubai's climate, mold on porous materials like concrete and carpet backing can penetrate deeply, and improper DIY removal can aerosolize spores throughout your villa.

A professional team will first identify and fix the AC leak to prevent recurrence. They then isolate the contaminated area with physical barriers and negative air pressure to prevent cross-contamination. The concrete will likely require specialized abrasive cleaning, and the carpet and underlay are almost certainly unsalvageable and must be disposed of. The process concludes with HEPA vacuuming and air scrubbing to remove airborne particles.

For a smaller patch on a non-porous surface, DIY with a bleach solution might be feasible. However, given the extent you describe, the hidden nature under carpet, and the strong musty odor indicating active colonization, a professional approach is the only way to ensure it is thoroughly and safely resolved. The humidity will cause it to return rapidly if not handled correctly. Look for a provider that offers a post-remediation verification test from an independent lab to confirm the space is within acceptable mold spore levels.
