AC mold from leak: DIY clean or professional needed?« Back to Previous Page

Based on the symptoms you've described—a significant leak, visible black mold spreading, and adverse health effects—this is a situation that absolutely requires professional assessment and remediation. In the UAE's high-humidity climate, what you see on the surface is often just a small portion of the problem. The moisture from your AC leak has almost certainly penetrated the drywall and insulation behind it, creating an extensive hidden reservoir of mold growth that bleach cannot reach.

Attempting a DIY clean with bleach is strongly discouraged. Bleach is ineffective on porous materials like drywall and wood, as it only bleaches the surface mold without addressing the root colony. Furthermore, improper cleaning can agitate the spores, releasing them into your air conditioning system and spreading the contamination throughout your villa, significantly exacerbating your wife's allergy symptoms.

Dubai's regulations, particularly from the Dubai Municipality, emphasize the importance of proper indoor air quality and mold management in residences. A professional company will not only remediate the visible mold but also conduct a thorough inspection using moisture meters and borescopes to assess the damage within the wall cavity. The process involves containment of the area with negative air pressure to prevent cross-contamination, safe removal of compromised building materials, specialized antimicrobial treatment, and finally, verification through post-remediation testing to ensure the spore count is returned to safe levels.

For a leak of this nature affecting an interior wall in a villa, costs can vary depending on the extent of the damage but typically start from AED 2,500 for a localized remediation project.

Given the health implications and potential for structural damage, I strongly recommend you cease use of that AC unit and contact a certified professional immediately.
