Urgent: Mold under shower sealant, need professional immediately?« Back to Previous Page

That discovery warrants immediate attention. The high humidity in Dubai, especially during summer months, creates ideal conditions for mold to thrive behind tiles and within wall cavities. The presence of black and green spots under the sealant strongly suggests an active moisture problem.

You should call a professional for an assessment immediately. While you can clean surface mold with a vinegar or diluted bleach solution, the fact it's under the sealant means the issue is likely deeper. A proper inspection can determine if there's hidden water damage or mold growth in the wall. Professionals use moisture meters and borescopes to see behind walls without causing unnecessary damage.

For a rental apartment in JVC, it's also important to notify your landlord or property management company as soon as possible, as this may be a building maintenance issue they are responsible for addressing. Do not wait until the weekend; the continued high humidity will allow it to spread further. A certified mold inspector can identify the source of the moisture and the extent of the growth, which is the critical first step before any remediation can be planned.
