What's a fair price for AC leak and mold removal?« Back to Previous Page

For a leak and mold patch the size of a dinner plate, expect the cost to be structured around two separate but connected jobs: fixing the AC condensate drain leak and the subsequent mold remediation.

The AC repair itself is typically the smaller part of the cost, often involving clearing a blocked drain line or sealing a connection. The mold remediation is more involved. A reputable company will first isolate the area, remove the affected drywall or plaster, HEPA-vacuum the cavity, treat it with an antimicrobial solution, and then repair the wall. The final cost is highly dependent on the extent of hidden damage behind the wall, which is common with slow leaks.

Given Dubai's high humidity and constant AC use, this is a moisture issue that must be solved at the source—the leak—before any mold is addressed. Otherwise, it will return. For a toddler's safety, professional remediation is advised over DIY, as improper cleaning can aerosolize spores.

Always request a detailed breakdown. A fair company will provide a scope of work that includes both the mechanical fix for the leak and the full remediation process, with post-clearance verification. Get multiple assessments to compare the proposed methodology, not just the bottom line.
