Should I DIY bathroom mold or call a professional?« Back to Previous Page

For small, surface-level mold on grout (under 1 square foot), a thorough DIY approach can work. Use a solution of distilled white vinegar or a dedicated tile and grout cleaner, scrub vigorously, and ensure the area dries completely. The key is not just cleaning but fixing the moisture source. In Dubai's high humidity, bathroom exhaust fans often aren't enough; run it for at least 30 minutes after showering and consider a small dehumidifier.

However, your description of a persistent smell and humidity that lingers suggests the issue may be deeper. Mold behind tiles or in the wall cavity is common here due to condensation from year-round AC use and minor, unnoticed leaks. This requires a professional inspection. A certified inspector uses moisture meters and borescopes to check inside walls without destructive testing, identifying the true moisture source—which is critical for a permanent solution. DIY surface cleaning in such cases often leads to rapid regrowth.

If the mold returns after a proper cleaning or the musty smell persists, an inspection is advised to prevent potential structural damage and health impacts from prolonged exposure.
