AC leak causing black mold: repair or mold inspection first?« Back to Previous Page

The AC in our villa in Al Barsha seems to be leaking into the wall behind it, and now we’re seeing these black spots spreading on the wallpaper. We’ve been ignoring a slight damp smell for a couple of weeks, but the stains are getting worse. Is a standard AC repair enough, or do I need to call a specialized mold inspection company to check inside the walls first?

Start with a mold inspection. An AC repair will fix the leak, but it will not address the microbial growth already present inside your wall cavity. The black spots on your wallpaper are a clear visual indicator of a colony, which suggests the hidden substrate behind is likely more developed.

In Dubai's high humidity, damp drywall and insulation become a perfect habitat for mold, which can spread rapidly through airborne spores from a source like this. A proper inspection involves using moisture meters and borescopes to assess the wall's interior damage without unnecessary demolition. This diagnosis is critical to understand the full scope before any remediation work begins.

For a villa in Al Barsha, ignoring this can lead to cross-contamination of your AC system and other rooms. The inspection will determine if the affected building materials can be cleaned or must be removed and replaced to solve the problem permanently. After the mold is fully remediated, the AC repair can be completed to prevent a recurrence.
