AC leak causing mold and health issues: how to fix?« Back to Previous Page

The situation you describe is a classic case of mold growth due to an unresolved moisture source, a common issue in Dubai's climate. The persistent AC leak has created the perfect environment for mold, particularly the black-spotted variety often associated with Stachybotrys or Aspergillus, both of which can cause the respiratory symptoms your husband is experiencing.

The most effective remediation is a systematic, professional process. First, and most critically, you must address the source. A certified HVAC technician must inspect and repair the AC unit to stop the condensation leak. Without this, any mold removal will be temporary.

For the mold itself, DIY cleaning with bleach is strongly discouraged. It is ineffective on porous surfaces like drywall and can exacerbate health issues by releasing spores and mycotoxins into the air. Proper remediation involves:

1. Containment: Sealing the area with plastic sheeting to prevent cross-contamination.
2. Removal: Physically removing and disposing of severely contaminated porous materials (the affected drywall and potentially the wardrobe backing).
3. HEPA Vacuuming & Abrasive Cleaning: Thorough cleaning of all surfaces with specialized equipment.
4. Antimicrobial Application: Using EPA-approved, non-toxic biocides to eliminate residual mold roots and inhibit regrowth.
5. Post-Remediation Verification: A clearance test to confirm spore counts are back to acceptable levels.

Given the health symptoms and extent of growth (spreading behind a wardrobe indicates a significant issue), this is not a DIY project. Professional remediation is essential to ensure it is done safely and effectively, complying with Dubai Municipality's standards for indoor air quality.
