How much to treat mold in Dubai villa, and is DIY possible?« Back to Previous Page

That vinegar likely fed the mould, which is a common mistake. In Dubai's high humidity, surface cleaning rarely works because the root moisture source and the hidden growth inside your walls remain the problem. Your husband's reaction is a clear indicator the spores are airborne.

For a spreading wall infestation in a villa, especially post-humidity, DIY is not a reliable solution. The treatment cost is entirely dependent on the extent of the damage behind the wall. A small, contained patch is a different project than if the mould has spread within the cavity, which requires removing drywall, treating the structure, and replacing insulation. The only way to get an accurate scope and cost is a professional inspection with a borescope to see inside the wall.

Reputable companies will provide a detailed assessment and a fixed-price quote for remediation, not an hourly rate. The final cost is determined by the square footage affected, the materials requiring treatment, and the necessary containment procedures to prevent cross-contamination. Always request this detailed quote in writing.

Given the symptoms and the fact it returned after cleaning, hiring a professional is necessary. They will identify and address the underlying moisture issue—often condensation from AC ducts in exterior walls or a minor leak—and perform the remediation with industrial-grade HEPA filtration to capture spores. This is the only way to ensure it doesn't return and to resolve the health symptoms.
