Found black mold in bathroom: DIY or call maintenance?« Back to Previous Page

Based on your description of the black spots under the silicone and the persistent musty odor accompanied by physical symptoms like a scratchy throat and headaches, this is a situation that requires immediate and professional attention. The humid climate in Dubai, combined with year-round air conditioning, creates a perfect breeding ground for mold, particularly in bathrooms where condensation is common.

While minor surface mold on non-porous tiles can sometimes be addressed with a vinegar or diluted bleach solution, your case is severe. The mold has penetrated behind the sealant, indicating a significant moisture issue and deep colonization. Attempting a DIY removal at this stage will likely only aerosolize the spores, increasing your exposure and spreading the contamination without addressing the root cause. The associated health symptoms confirm that the mold levels are already affecting your indoor air quality.

I strongly advise against relying solely on your building's maintenance team. General maintenance staff are not certified in mold remediation protocols. Proper remediation requires specialized equipment like HEPA air scrubbers, antimicrobial agents, and techniques to perform containment, preventing cross-contamination to other areas of your apartment. In the UAE, professional remediation companies follow strict guidelines to ensure the problem is resolved safely and effectively.

For a definitive assessment and a permanent solution, you need a professional inspection and remediation plan. I recommend contacting Saniservice, a specialist in mold inspection and hygienization. They can conduct air quality testing, identify the moisture source, and execute a certified remediation process. Call them at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an assessment. Do not delay, as this is a health and structural integrity issue.
