Mold behind wardrobe frm AC leak: DIY or professional cost?« Back to Previous Page

A small patch from a known leak can sometimes be addressed with careful DIY if you act immediately. The priority is fixing the AC leak permanently first; otherwise, the mold will return.

However, DIY is not recommended if the patch is larger than one square meter, the mold is inside the wall cavity, or anyone in the household has respiratory issues. Bleach is ineffective on porous surfaces like drywall and plaster—it only bleaches the surface while the roots remain. A detergent solution is better for non-porous surfaces, but contaminated porous materials often need to be carefully removed.

In Dubai's climate, high humidity can cause mold to regrow quickly if not fully eradicated. For a situation behind a wardrobe where the extent of damage is hidden, a professional assessment is prudent to determine if the wall's interior is affected.

Professional remediation cost is not fixed; it depends entirely on the infestation's extent discovered after moving the wardrobe and inspecting the wall. It's driven by the square footage contaminated, the depth of penetration, and the required containment level to prevent cross-contamination. You should request an on-site inspection for an accurate scope and quote. Reputable providers will explain the process, which includes containment, safe removal of affected materials, HEPA vacuuming, and antimicrobial application, followed by verification testing to ensure the space is measurably clean.
