AC leak causing black mold: DIY bleach or call pro?« Back to Previous Page

Black mold growth from an AC leak is a health risk that requires immediate and careful action. Given the UAE's high humidity and year-round AC use, this environment allows mold to thrive, especially from persistent moisture like a leak. Your husband's increased sneezing is a common reaction to mold spores.

While a small surface patch might be addressed with a DIY approach, your situation involves a leak that has soaked into the wall and carpet, creating a larger hidden problem. Bleach is not recommended; it is mostly water, which can feed the mold roots deep in porous materials, and its fumes are hazardous in a bedroom. For porous surfaces like drywall and carpet, effective removal is nearly impossible—they typically require replacement.

You should call a professional. Dubai Municipality guidelines for water damage restoration emphasize containing the area to prevent spore spread, safely removing contaminated materials, and using industrial-grade HEPA filtration. A proper remediation will first fix the AC leak at its source, then address the visible and hidden mold. For health validation, a post-remediation test from an independent lab is the only way to confirm the space is safe.
