AC mold from leaking unit: DIY or call professional?« Back to Previous Page

The visible mold is likely just the surface issue. In Dubai's high humidity, a leaking AC unit creates persistent dampness inside your wall cavity, allowing hidden mold to thrive. Vinegar only addresses surface growth and won't stop the root moisture problem.

For a recurring leak and spreading dampness, this requires a professional assessment. The remediation cost is driven by the extent of hidden damage, not just the visible patch. Treatments for a small area typically involve containment, removing affected materials like drywall or insulation, HEPA vacuuming, and antimicrobial application to ensure the structure is dry and treated at the source.

Your first step is to stop the leak by having your AC unit serviced. Then, contact a certified mold inspector who can use moisture meters and borescopes to assess the wall's interior. They should provide a detailed protocol and post-remediation verification, often with lab testing, to confirm the space is truly dry and mold-free. This is the only way to prevent it from returning.
