Need pro for black mold inside wall from AC leak?« Back to Previous Page

Based on your description, this is a serious situation that absolutely requires professional mold remediation. The black mold spreading from an AC leak inside a wall cavity is a classic and high-risk scenario we frequently encounter in Dubai.

Bleach is ineffective for this type of problem. It only bleaches the surface pigment of the mold you can see but does not kill the roots (hyphae) penetrating the porous wall material. The persistent, strong smell is a clear indicator that the microbial colony is still active and likely much more extensive inside the wall. In Dubai's climate, with high year-round humidity, this mold will continue to proliferate rapidly if the moisture source isn't eliminated and the contaminated materials are not properly remediated.

The remediation process is technical. It involves isolating the area to prevent cross-contamination, safely removing the affected drywall and insulation, HEPA vacuuming, and applying professional-grade antimicrobial agents. Crucially, the AC leak must be repaired by a certified HVAC technician to prevent immediate recurrence. This is not a DIY job; improper handling can aerosolize toxic spores, significantly worsening indoor air quality and potential health risks.

For a villa in Jumeirah 3, costs can vary based on the extent of the damage behind the wall, but you should anticipate a professional remediation project starting from approximately AED 3,000 to AED 8,000 or more. This includes a detailed inspection, containment, remediation, and verification testing to ensure the space is safe.
