How to find and fix moisture in my closet wall?« Back to Previous Page

The black spots on your leather items are a strong indicator of a moisture problem within the wall cavity, which is common in Mirdif villas after humid periods. The exterior wall likely has a breach or insufficient insulation, allowing warm, humid air to penetrate and condense on the cooler interior surfaces, creating the perfect environment for mold growth on organic materials like leather and the wall itself.

To find the source, start by inspecting the exterior wall for any visible cracks, gaps around pipes, or damaged waterproofing. Inside, a non-invasive moisture meter can detect elevated moisture levels within the wall without damaging it. For a definitive diagnosis, a professional inspection using a borescope—a small camera inserted through a tiny hole—can visually confirm mold growth and moisture inside the wall.

Fixing it requires addressing the root cause. Any exterior breaches must be sealed by a qualified technician. Internally, the affected section of drywall and insulation will likely need to be removed to properly remediate the mold colony, treat the cavity with antimicrobial solutions, and allow the structure to dry completely before rebuilding with new, mold-resistant materials. Simply cleaning the surface will not stop the problem from returning.

Given Dubai's climate, ensuring your AC is properly sized and running consistently in that room can help manage indoor humidity levels and prevent future condensation issues. For a problem suspected inside the wall, a professional assessment is crucial to prevent structural damage and ensure the remediation is done to Dubai Municipality standards.
