AC mold in Jumeirah Village Circle: DIY or professional cost?« Back to Previous Page

A leaking AC unit causing black spots on the wall is a common issue in Dubai's humid climate, and this requires professional attention. The visible mold is likely just the surface growth; the real problem is the moisture trapped inside your wall cavity from the leak, which will continue to fuel mold spread until the source is fixed.

For a situation like this, DIY cleaning is not recommended. Surface wiping with bleach or vinegar will only remove the cosmetic stains temporarily. The hidden mold colony within the wall will remain and return quickly. The process requires stopping the AC leak, identifying the full extent of moisture damage, and properly remediating the affected wall section to prevent spores from spreading during cleanup.

You should expect a professional assessment to include three parts: fixing the AC leak to stop the moisture source, a detailed inspection (often with a borescope) to see inside the wall, and the actual remediation work. The cost is not based solely on the small visible area but on the labor to contain the area, remove contaminated materials like drywall or insulation, and treat the cavity. For a single interior wall, the price is typically driven by the extent of damage found and the time required for proper containment and drying.

Request a detailed assessment from a provider that uses moisture meters and can explain their containment process. Any reputable company should be able to provide a clear scope of work and quote after an on-site inspection.
