Should I treat bathroom mold myself or call maintenance?« Back to Previous Page

For a small patch (under one square foot) in a Marina apartment, DIY treatment is often effective. Start by mixing a solution of one part distilled white vinegar with one part water in a spray bottle; vinegar is effective against many common mold types and is less harsh than bleach. Spray the area thoroughly, let it sit for an hour, then scrub with a stiff brush. After cleaning, ensure the area is completely dry—use a squeegee on walls after every shower and run the bathroom's exhaust fan for at least 30 minutes.

However, the cracked grout and location at the ceiling-wall junction are significant concerns. This suggests a persistent moisture issue, likely from condensation from your AC or steam penetration. In Dubai's high humidity, surface cleaning often fails if the underlying moisture source isn't addressed. The crack needs proper sealing to prevent moisture from migrating into the wall cavity, which is a job for maintenance.

You should call your building's maintenance immediately. They need to inspect and properly seal the cracked grout to stop the moisture intrusion. For extensive hidden mold, a professional inspection with moisture meters can identify the full scope. If the mold returns after maintenance repairs, that would indicate a deeper issue requiring professional assessment.
