How to permanently remove mold and find hidden leaks?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots appearing along the wall behind our sofa in the master bedroom. It’s an interior wall, and the room always feels damp even with the AC on. What’s the best way to get rid of this mold for good and who should I call to check for a hidden leak?

The persistent damp feeling and mold on an interior wall strongly suggest a hidden moisture source, likely a leak from a pipe within the wall or condensation from an AC line. In Dubai's climate, AC units can produce significant condensation; if the drain line is blocked or improperly insulated, it can cause constant dampness.

For permanent removal, simply wiping the visible mold is insufficient. The wall must be opened to locate and repair the leak. The affected drywall and insulation are probably compromised and need replacement. A professional inspection is essential to diagnose the exact cause. They will use moisture meters and thermal imaging cameras to pinpoint the leak's origin without unnecessary damage.

You should call a licensed building maintenance or plumbing company to investigate and repair the leak. For the mold remediation itself, ensure the company follows proper containment and removal protocols to prevent spores from spreading. Once the leak is fixed and the area is completely dry, the wall can be rebuilt.

To prevent recurrence, maintain indoor humidity below 60% using a dehumidifier if necessary. Ensure your AC unit is serviced regularly, with particular attention to cleaning the drain pan and line to prevent future condensation issues.
