What's the cost to fix small AC mold leak?« Back to Previous Page

The AC in our Jumeirah Park villa has been leaking a bit into the wall behind it, and now we’ve spotted a decent-sized patch of black mold there, about the size of a dinner plate. It’s been getting worse since the last humidity spike a couple of weeks ago. I'm worried about it spreading but also don't want to get ripped off. What’s the typical ballpark cost for professional mold remediation for a small area like this, and is it a complete DIY no-go?

The situation you're describing in your Jumeirah Park villa is a common yet serious issue here in Dubai, primarily driven by our high humidity levels and the year-round reliance on AC systems. The condensation from a leaking AC unit creates a constant moisture source, which is the primary catalyst for mold growth like the black patch you've observed.

For a contained area approximately the size of a dinner plate, professional remediation is strongly advised over a DIY approach. Attempting to remove it yourself can aerosolize the spores, leading to cross-contamination and potential health issues. A certified professional will first conduct a thorough inspection to assess the extent of the damage, including any hidden growth within the wall cavity, which is highly likely. They will then set up containment, use HEPA filtration to clean the air, and safely remove the contaminated materials.

Regarding cost, for a small, localized remediation project like this, you can expect a ballpark figure ranging from AED 1,500 to AED 3,500. This typically includes the initial assessment, containment, removal of affected drywall or insulation, antimicrobial treatment of the cavity, and a post-remediation verification test to ensure the space is safe. The final cost depends on the penetration depth into the wall and the accessibility of the leak.

The most critical step is to fix the underlying AC leak; otherwise, the mold will return. For a precise quote and a compliant solution adhering to Dubai Municipality's health and safety standards, I recommend a professional inspection.
