Should I DIY small black mold or call a pro?« Back to Previous Page

A small patch of black mold from a known AC leak can often be addressed yourself if the underlying moisture issue is fully resolved. The first step is to fix the AC leak completely; otherwise, the mold will return. For a surface area that size, a solution of detergent and water is more effective than bleach, which only removes surface discoloration and does not kill the mold roots.

Given Dubai's high humidity, the damp feeling in the room suggests a deeper moisture issue. Mold can penetrate porous materials like drywall and insulation, which you cannot properly clean. A professional inspection is recommended to assess the full extent, as hidden growth inside the wall cavity is common here after a leak. They use moisture meters and thermal cameras to find all affected areas.

For remediation, the cost for a small, contained job like a closet is generally on the lower end of the scale, but prices vary based on the extent of damage and materials affected. You should request an on-site assessment for an accurate quote. The process should include physical removal of contaminated porous materials, HEPA vacuuming, and antimicrobial treatment of the area, not just surface wiping. Always ask for before-and-after documentation to verify the job's completeness.
