AC mold behind wardrobe: DIY or professional for JVC apartment?« Back to Previous Page

This is a professional job, not a DIY fix. The mold you see on the surface is just the fruiting body; the actual fungal network (mycelium) is likely growing deep within the wall and insulation behind the wardrobe. Vinegar or store-bought sprays only bleach the surface and can agitate the spores, causing them to release and spread further, which explains why it came back darker.

The root cause is the ongoing AC leak, which has created a persistent moisture source inside your wall cavity. In Dubai's high humidity, this creates a perfect environment for mold to thrive. Simply cleaning the visible patch without addressing the hidden moisture and the extensive contamination is ineffective.

You need a professional assessment. A certified inspector will use a moisture meter to find the leak's extent and a borescope to see inside the wall, determining how far the mold has spread. The remediation process involves isolating the area, removing contaminated drywall and insulation, treating the cavity with antimicrobial solutions, and then repairing the leak and the wall. For a small, contained area like this, the scope is typically manageable, but the final cost depends entirely on the depth of the damage found during the inspection. Always request a detailed scope of work and ensure the company provides before-and-after lab testing to verify the space has been returned to a healthy condition.
