Dealing with recurring shower mold; need professional in Dubai?« Back to Previous Page

We've lived here for 2 years and just noticed black spots growing along the grout in our master bathroom shower. It’s in the corner that gets no sunlight and the musty smell is getting worse. I tried a bleach spray but it came right back after a week. Is this a job for a professional cleaning company or can I handle it myself, and what’s the typical cost in Dubai for a proper mold removal service?

Recurring shower mold in Dubai is extremely common due to our high humidity and condensation from year-round AC use. Bleach only removes surface discoloration but doesn't kill the root structure embedded in porous grout, which is why it returns so quickly.

For a small, surface-level patch, scrubbing with a dedicated fungicidal cleaner (not bleach) can be effective. However, since you mention a persistent musty smell, the mold has likely penetrated deeper into the grout or the wall substrate behind it. This requires professional remediation to prevent structural damage and potential health issues from airborne spores.

In Dubai, a proper remediation involves isolating the area, removing the affected grout, treating the substrate with antimicrobial solutions, and regrouting with mold-resistant materials. The cost is not fixed; it depends entirely on the square footage of affected area and the depth of the infestation. For a standard shower corner, expect a range from a few hundred dirhams for a surface treatment to a more significant amount if tile and grout removal is necessary.

Always request an on-site inspection for an accurate assessment and a detailed quote that includes post-remediation verification, such as moisture readings, to ensure the source of moisture has been addressed.
