How to properly inspect for mold after AC and leak issues?« Back to Previous Page

A proper mold inspection starts with identifying the moisture source, as mold cannot be addressed without first stopping the water. In your case, the past leak and constant AC use in Dubai's humidity are classic culprits. The black spots on the ceiling are a strong visual indicator, but the main colony could be hidden inside the wall cavity or the AC ductwork.

For a situation with a prior leak, a professional inspection is strongly recommended. They will use a combination of tools you cannot access, such as a borescope to see inside walls and moisture meters to detect dampness you can't feel. Air and surface sampling are often part of a thorough investigation; these samples are sent to an accredited microbiology lab to identify the specific mold types and concentrations, which dictates the correct remediation protocol.

A proper inspector will provide a detailed report mapping the affected areas and identifying the exact moisture problem. This is critical because simply wiping away visible spots without addressing the hidden source or the AC unit itself guarantees it will return. In Dubai, where AC systems are a primary vector for spreading spores, the inspection must include the ductwork and evaporator coil. The goal is a full diagnosis, not just a surface-level look.
