AC leak causing mold on wall: professional fix and cost?« Back to Previous Page

This is a common and serious issue in Dubai's climate. The persistent condensation leak is actively feeding the mold colony inside your wall cavity. This is not a surface cleaning job; it requires professional remediation to prevent structural damage and health risks, especially for your toddler.

First, fix the AC leak. This is the critical first step—any remediation will fail if the moisture source isn't stopped. A certified HVAC technician needs to diagnose and repair the drain line or insulation issue causing the condensation leak.

For the mold, a specialized remediation company is necessary. They will isolate the area, remove affected drywall, treat the cavity with antimicrobial solutions, and install new materials. The hidden growth in the wall is the real concern, not just the visible stains. In the UAE, look for providers who hold DM-approved licenses and can provide a post-remediation verification report from an independent lab to confirm the spore count has been returned to safe levels.

Budgeting is difficult without knowing the extent of the damage behind the wall. Costs are driven by the square footage of contamination and the complexity of the repair. For a standard bedroom wall, expect a range covering diagnostics, containment, removal, and reconstruction. Always get a detailed, fixed-price site assessment before any work begins.
