Urgent: how to treat AC mold behind skirting boards?« Back to Previous Page

Stop using the AC in that room immediately and restrict access, especially for children, elderly, or anyone with asthma. The combination of a persistent leak and Dubai's high humidity has created an ideal environment for extensive mold growth, which has almost certainly spread into the wall cavity behind the skirting board.

For a situation this advanced, a two-step professional process is the only effective solution. First, a certified mold inspector should conduct a thorough assessment, including moisture mapping and possibly borescope inspection behind the skirting, to determine the full extent of the contamination. This is critical for planning the remediation.

The remediation itself involves containment; professionals will seal the area with plastic sheeting to prevent spores from spreading to other parts of your villa during the work. They will then remove the affected skirting boards, sections of wet drywall, and contaminated carpet. All moldy materials must be bagged and disposed of properly. The underlying area and any structural elements will then be HEPA vacuumed and professionally cleaned with antimicrobial solutions. A dehumidifier and air scrubber will be used to dry the area completely and purify the air before repairs are made.

Do not attempt to bleach or scrub it yourself, as this will aerosolize the spores and likely exacerbate the problem. The speed of treatment depends on securing a reputable Dubai-based remediation company that follows IICRC standards. They can typically mobilize for an assessment within 24-48 hours for urgent cases. Ensure the company you hire provides full documentation of the removal process and post-remediation verification, often through third-party testing, to confirm the space is safe.
