AC leak causing mold and toddler illness: professional remediation cost?« Back to Previous Page

For a leak that's been active for months with visible growth and a toddler in the home, a professional inspection is strongly recommended. The combination of persistent moisture and Dubai's high ambient humidity creates an ideal environment for mold, and the proximity to a sleeping area increases exposure.

The black patches are very likely Cladosporium or Aspergillus, which are common here due to condensation in AC systems. These types are known irritants and can cause the exact respiratory symptoms you're describing, especially in young children. The first step is to stop the source—get the AC unit repaired to prevent further leakage.

For remediation, you'll need two professionals: an HVAC technician to fix the leak and a separate mold inspection and remediation company. Do not use a general handyman for this. Reputable remediators will first conduct an inspection, often involving air and surface sampling sent to an independent lab like ours to identify the species and spore count. This diagnosis is crucial.

The cost isn't fixed; it depends entirely on the extent of the spread behind the wall, which isn't yet visible. Removal involves isolating the area, physically removing contaminated materials like drywall or insulation, HEPA vacuuming, and antimicrobial treatment. For a contained area behind an AC unit, the process is typically manageable. You must request a detailed scope of work and a final verification test to confirm the space is safe before they leave. Get assessments from several certified providers.
