Cost to fix AC leak and black mold in Dubai?« Back to Previous Page

We've lived in our Jumeirah villa for 2 years and just noticed a large patch of black mold in the corner of our master bedroom closet, probably from a hidden AC leak. It's about a meter wide and has that classic damp smell. I'm worried about my family's health, but I have no idea if this is a small job or a huge ordeal – can anyone give me a rough estimate of what it might cost to get this professionally treated and the AC fixed?

Based on your description, this is a serious issue that requires immediate professional attention. A one-meter patch indicates significant moisture intrusion, likely from a compromised condensate drain line or a faulty drain pan in your AC unit, a common problem in Dubai's climate due to year-round AC operation and high humidity leading to constant condensation.

The cost is not a single figure but is broken down into two essential and separate scopes of work. First, the AC repair by a certified HVAC technician to fix the leak at its source, which could range from AED 500 for a simple drain line unclogging to AED 2,000+ if the evaporator coil or drain pan needs replacement.

Second, and most critically, the mold remediation. Due to the size and the fact it's in a bedroom closet (posing a direct health risk from spores), this is not a DIY job. Professional remediation involves containment, HEPA filtration, antimicrobial treatment, and possibly removal of affected porous materials like drywall. For a patch of that size, you should budget between AED 3,000 to AED 8,000+ for a proper, certified remediation process that includes post-clearance testing to ensure the environment is safe. This is in line with best practices and Dubai Municipality's public health guidelines for fungal contamination.

You absolutely need a professional mold inspection first to assess the full extent, as hidden growth behind walls is highly probable. Do not disturb the area, as this will release spores.
