AC mold behind unit: professional remediation needed and cost?« Back to Previous Page

Yes, professional remediation is strongly recommended for your situation. The recurring mold after bleach cleaning indicates it has penetrated beyond the surface, likely into the drywall or insulation. In Dubai's high humidity, this allows it to spread unseen.

The immediate priority is fixing the AC leak—this is the moisture source. Until that's resolved, any cleaning is temporary. For a small wall patch, remediation involves isolating the area, removing contaminated materials, treating the cavity with antimicrobials, and properly drying it before repair. A reputable company will also use air scrubbers to contain spores.

Cost is variable and depends on the extent of hidden damage. It's not just the visible spot; the leak may have caused mold inside the wall. Expect pricing to reflect the containment setup, labor, and materials rather than just square footage. Always request a detailed assessment and quote that explains the full scope of work. Companies accredited by the Dubai Municipality or with certified mold remediators on staff typically follow the most rigorous protocols.
