AC mold in Dubai: urgent fix or DIY? Cost?« Back to Previous Page

This is a job for a professional. In Dubai's high humidity, what you see on the wall is often just the surface manifestation; the real colony is likely inside the wall cavity and AC unit itself, spreading through spores. A DIY approach with bleach or vinegar only addresses the visible stain and can aerosolize spores, worsening the problem.

The leak must be repaired first, as ongoing moisture will cause mold to return immediately. A proper remediation involves isolating the area, removing contaminated drywall and insulation, HEPA vacuuming, and antimicrobial treatment of the cavity. The AC drip pan and drain line also need a thorough cleaning to prevent recirculation.

For cost, it depends entirely on the extent of the damage behind the wall. A small, contained patch is a different scope than a large infestation that has saturated the insulation. Reputable companies provide a detailed assessment and quote based on square meterage of affected area. Always request a post-remediation verification test from an independent lab to confirm the space is safe; this is your proof the job was done correctly.
