Should I hire a pro for shower mold or DIY?« Back to Previous Page

It depends on the extent of the growth behind the sealant. In JVC's high-humidity environment, surface mold on silicone is common, but hidden growth within the wall cavity is the real concern. If the mold is only on the surface and the underlying wall is solid and dry, a DIY approach can be effective.

For a DIY clean, skip bleach—it’s mostly water and can feed deeper mold roots while posing respiratory risks. Instead, use a dedicated mold remover or a paste of baking soda and vinegar. Scrub thoroughly, let it sit, then rinse. The critical step is to run a dehumidifier or your AC continuously for 24-48 hours after cleaning to ensure the area is completely dry before reapplying new sealant. Simply running the exhaust fan often isn't enough to combat Dubai's ambient humidity.

You should consider a professional assessment if the drywall behind feels soft or crumbly (indicating moisture damage), if the area is larger than a square foot, or if household members have respiratory sensitivities. Pros use moisture meters and borescopes to check for hidden saturation in walls, which is a common issue here. Remediation is less about cleaning visible mold and more about diagnosing and solving the persistent moisture problem that caused it.
