Should I call a pro for black spots on my wall?« Back to Previous Page

Black spots on an interior wall, combined with a damp feeling, are strong indicators of a mould colony and an underlying moisture issue. In Dubai's climate, this is most often caused by condensation from AC systems or a hidden leak.

You should call a professional for an inspection this week. The priority is identifying and stopping the moisture source; otherwise, the mould will return even if you clean the spots. Since it's behind furniture and the wall feels damp, the extent behind the surface is unknown. A professional inspection uses moisture meters and borescopes to assess the wall cavity without unnecessary damage.

For a small, visible patch, you can clean it with a vinegar solution, but this is only a surface fix. Move the wardrobe away from the wall to improve air circulation, which can help reduce condensation. Ensure your AC is set to a consistently cool temperature, as frequently turning it off and on encourages humidity spikes indoors.

The Dubai Municipality has clear guidelines on indoor air quality, and a certified inspector can determine if the situation requires formal remediation. Given the duration you've been there and the recent appearance, it's better to get a definitive assessment now rather than wait.
