Is hidden shower mold serious, DIY or call pro?« Back to Previous Page

My ensuite bathroom in our Jumeirah apartment has had this musty smell for weeks, but I just pulled back the silicone sealant around the shower and found a bunch of black and green spots underneath. It's been so humid lately that the mirror never clears. How serious is this? Should I be calling a professional cleaning service ASAP, or is it something I can handle myself with vinegar over the weekend?

Based on your description of the situation in your Jumeirah apartment, this is a serious issue that requires professional attention, not a DIY approach. The black and green spots you've discovered beneath the silicone are a significant growth of mold, likely including species like Aspergillus or Stachybotrys (black mold). The persistent musty odor and high humidity are classic indicators of an active colony.

The climate in Dubai, characterized by extreme humidity and year-round air conditioning, creates a perfect breeding ground for mold. Condensation forms on cold surfaces like mirrors and tiles, and this moisture gets trapped behind seals and within wall cavities. Simply applying vinegar or store-bought cleaners only addresses the surface discoloration you can see; it will not eliminate the deeply rooted fungal hyphae or the mycotoxins they can produce. More importantly, disturbing the mold by scrubbing it can aerosolize spores, potentially leading to respiratory issues and allergic reactions for you and your family.

In the UAE, professional mold remediation is governed by strict health and safety standards. A certified inspector will conduct a thorough assessment, often including moisture mapping and air quality testing, to determine the full extent of the infestation hidden within the walls. Proper remediation involves containment of the area, professional-grade antimicrobial agents, and the safe removal and replacement of contaminated materials like the silicone sealant and potentially the underlying grout.

For a comprehensive inspection and a guaranteed remediation solution, I strongly recommend you contact our specialists at Saniservice. Call 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an assessment. Addressing this properly now will protect your health and your property.
