AC mold in Dubai apartment: professional cost and need?« Back to Previous Page

Yes, you should hire a professional for this. A dinner-plate-sized patch indicates significant moisture, and the location behind the AC unit suggests it has likely spread into the wall cavity and insulation, which you cannot see. In Dubai's high humidity, this hidden growth is common and will recur if not addressed properly.

The cost is not just for cleaning the wall; it involves a full assessment of the AC unit and the moisture source, containment to prevent spores spreading during work, removal of contaminated materials, and antimicrobial treatment. For a single wall, expect the scope to be more involved than a simple surface clean. Reputable companies provide detailed scopes of work and pricing only after an on-site inspection, as the final cost depends entirely on the extent of the hidden damage.

For your allergies, do not disturb the area. Avoid using bleach or DIY solutions, as improper cleaning can aerosolize spores and worsen your symptoms. A professional inspection, often involving moisture meters and possibly air testing, will identify the full extent and the root cause—typically a clogged AC drain line or poor insulation causing condensation, both extremely common here. They can then provide a verifiable remediation plan with before-and-after documentation.
