Black mold from AC leak, cost to remediate in Dubai?« Back to Previous Page

Black mould from an AC leak is a very common issue in Dubai, especially in areas like JVC, due to high humidity and year-round AC use causing condensation problems. The leak provides constant moisture, and simply wiping the mould is ineffective as the colony is growing deep within the wall.

For a spreading patch, professional remediation is strongly advised. The process typically involves identifying and fixing the AC leak source first, then isolating the contaminated area, removing affected drywall and insulation, HEPA vacuuming, and applying antimicrobial treatments to prevent regrowth. The final step should always be post-remediation verification (PRV) testing by a third-party to confirm the spore count has returned to safe, background levels.

Costs are highly variable and depend on the extent of damage behind the wall, which isn't visible. For a contained bedroom wall leak, expect a range based on the square footage of contamination and the required demolition and reconstruction. Always request a detailed, on-site inspection and a scope of work that includes the fix, removal, treatment, and—crucially—the post-remediation lab test to verify the results. This ensures you're paying for a solution, not just a temporary cover-up.
