AC unit leak causing mold: DIY or call a pro?« Back to Previous Page

That black spotting is a classic sign of active mold growth, almost certainly fueled by the AC leak and our high Dubai humidity. This requires immediate action, but the correct approach depends on the extent.

For a small, surface-level patch (under ~1 sq. ft.), you can attempt a DIY cleanup. Use a microfiber cloth and a solution of diluted white vinegar or a dedicated mold remover from a hardware store. Wear an N95 mask and gloves. However, this is a temporary fix if the moisture source isn't eliminated. The AC leak must be repaired by a qualified HVAC technician first, or the mold will return.

Given the mold is behind a wardrobe and has been spreading for weeks, a professional assessment is strongly recommended. The wall cavity or backing of the wardrobe may harbor a larger, hidden colony that DIY wiping won't address. Professionals use moisture meters and thermal imaging to find the full extent of the water damage and contamination. They then contain the area to prevent spores from spreading during removal and use HEPA filtration to clean the air.

The cost for professional remediation is not fixed; it varies significantly based on the square footage affected, whether contents need moving (like the wardrobe), and if structural materials like drywall require replacement. For a single room, you should request an on-site inspection from a certified mold remediation company to get an accurate assessment and quote. Look for companies that provide detailed lab reports to verify the mold type and confirm the cleanup was successful.
