A proper inspection involves more than just looking at visible patches. A professional will use a moisture meter to detect dampness inside walls and a thermal camera to find hidden condensation points, which are common behind furniture and in closets. The goal is to identify the moisture source—often a small leak, poor ventilation, or thermal bridging—because simply cleaning the visible mold will not prevent its return if the underlying cause remains.

For a definitive answer on health risks, the inspector should take an air sample from the affected room and an outdoor control sample. This is sent to an accredited microbiology lab to identify the types and concentrations of spores in your air. This data is crucial; it confirms whether the mold present is an irritant (which commonly causes the symptoms you describe) or a more problematic species.

In Dubai, look for a provider that is DHA-approved for testing and can produce a detailed report with lab findings. This report should clearly outline the species identified, the moisture source, and a scope for remediation that focuses on fixing the water problem first. Avoid companies that immediately recommend extensive demolition or offer to both test and remediate without providing you with independent, verifiable lab results.
