AC leak caused mold under carpet, how to fix?« Back to Previous Page

The situation you're describing is a serious Class 2 water damage and mold contamination event, a common yet hazardous issue in Dubai apartments, particularly in older buildings in areas like Deira. The constant AC operation combined with our high ambient humidity creates a perfect environment for rapid mold proliferation, especially in concealed cavities.

The first and most critical step is to cease all use of the affected AC unit and isolate the room to prevent cross-contamination of mold spores into other living areas. Do not attempt to clean this yourself, as disturbing the mold will aerosolize toxic spores, posing a significant health risk and violating Dubai Municipality's public health guidelines for fungal contamination.

A professional remediation is mandatory. The process involves:
1. Containment & Engineering Controls: Erecting negative air pressure containment with HEPA-filtered air scrubbers to seal the area, as per DM standards.
2. Carpet & Padding Removal: The carpet and its soaked padding are unsalvageable and must be carefully removed and bagged for hazardous disposal.
3. Subfloor Treatment: The concrete subfloor will require abrasive cleaning (e.g., sanding, wire-brushing) followed by application of an EPA-approved antimicrobial biocide to kill the root structure.
4. Drying: Using industrial-grade dehumidifiers and air movers to achieve a dry standard of less than 15% moisture content in the slab.
5. Post-Remediation Verification: A third-party clearance test is crucial to confirm spore counts have returned to ambient levels before new flooring is installed.

To prevent recurrence, the root cause—the AC leak—must be addressed. This is typically due to a clogged condensate drain line, a faulty drain pan, or insufficient insulation causing excessive condensation. A certified HVAC technician must service the unit to clear the drain line and ensure proper drainage.

For a situation of this severity, I strongly recommend you contact a certified professional immediately.
