How to professionally remove mold under AC and prevent it?« Back to Previous Page

That's a serious situation that requires immediate and thorough action. Given the visible growth and the AC leak as a confirmed moisture source, this is not a DIY project. The combination of a constant water source and Dubai's high humidity creates an ideal environment for mold to thrive and spread within your wall cavity and subfloor.

The most effective approach starts with a professional inspection by a certified mold assessor. They will identify the full extent of the contamination, including what's hidden behind walls or under the floor, and determine the moisture source. The AC unit and its drainage line must be inspected and repaired by a qualified HVAC technician to stop the leak permanently; otherwise, the mold will return no matter how well you clean.

For remediation, the process must be contained to prevent spores from spreading to other parts of your villa. The affected carpet and underlay will almost certainly need to be removed and disposed of. The subfloor will then need to be professionally cleaned with specialized antimicrobial agents. In many cases, heavily contaminated porous materials like drywall or insulation must be removed and replaced. Air scrubbers with HEPA filtration are used during this process to capture airborne spores.

To ensure it doesn't come back, the area must be completely dried using industrial-grade dehumidifiers, verified with moisture meters. Finally, a post-remediation verification test, ideally from an independent third party or a company with its own microbiology lab, is essential. This test provides concrete evidence that the spore count inside the contained area has been returned to safe, ambient levels, confirming the cleanup was successful.
