Urgent: Mold under tub sealant, need professional cleaning?« Back to Previous Page

That discovery warrants immediate attention. The mold under the sealant is likely feeding on trapped moisture within the wall, which is a common issue in Dubai's high humidity where condensation constantly forms on cold surfaces like windows and tiled walls.

For a small, surface-level patch, you could attempt cleaning with a dedicated mold remover from a hardware store. However, the fact it's under the sealant and causing a persistent musty smell strongly suggests a deeper, established colony. DIY cleaning often only addresses the visible surface, leaving the root cause intact. The risk is that disturbing it without proper containment can release a high concentration of spores into your apartment.

In this scenario, a professional assessment is the most prudent step. They can determine the extent of the infiltration behind the tiles and tub. Remediation involves carefully removing the contaminated sealant, treating the underlying area with industrial-grade biocides, and ensuring the space is thoroughly dried before applying new, high-quality sealant to prevent recurrence. For verifiable results, seek a provider that can document the process with before-and-after moisture readings or even lab samples to confirm the species and that the treatment was effective.
