AC leak causing wall mold: call a pro for fix?« Back to Previous Page

Yes, you should call a professional. A recurring mold patch after a DIY treatment, especially with an active AC leak, means the moisture source isn't resolved. In Dubai's high humidity, this situation will only worsen, allowing mold to spread into the wall cavity and potentially the AC unit's internal ductwork, which becomes a much larger contamination issue.

The job requires two separate specialists: an HVAC technician to diagnose and permanently fix the condensate drain line or pan leak, and a mold remediation expert to properly assess and remove the contaminated wall section. Simply cleaning the surface is ineffective once mold has penetrated porous materials like drywall. Professionals will isolate the area, safely remove the affected material, treat the framing, and replace it, ensuring the spores are contained.

Cost is variable and depends entirely on the extent of the water damage and mold growth behind the wall. A small, contained patch will be a modest project, while extensive damage requiring wall reconstruction and AC servicing will be more involved. The only way to get an accurate assessment is to have a certified inspector open the area to see the full scope; any quote given before a proper inspection is just an estimate. For companies with their own microbiology lab, they can also test to confirm the mold type and verify the cleanup was successful, which is recommended for peace of mind.
