Should I hire a pro for black grout in my kitchen?« Back to Previous Page

That black grout is a classic sign of a persistent moisture issue, common in Dubai's humid climate where surfaces never fully dry. Bleach only removes surface discoloration and can drive mold deeper into the porous grout and the substrate beneath the tiles.

This is likely more than a surface cleaning job. The previous leak suggests moisture has penetrated behind the tiles, feeding mold growth in the cement bed and possibly compromising the adhesive. A professional inspection is necessary to assess the extent of the damage. They will use moisture meters and borescopes to see what's happening underneath.

For a 20-square-meter kitchen, the process typically involves a full assessment, isolating the affected area with containment barriers to prevent spore spread, and specialized deep-cleaning of the grout lines. In many cases, the grout must be completely removed and replaced after the underlying area is treated and dried. Given the high humidity, a professional-grade dehumidifier is essential post-treatment to ensure the area is bone-dry before re-grouting to prevent immediate recurrence.

The cost for a proper remediation job is not trivial, as it involves diagnostic labor, specialized equipment, and materials. You should obtain several detailed assessments from companies that can explain their diagnostic process and provide a scope of work, not just a superficial cleaning quote. Avoid services that promise a quick fix without addressing the root moisture problem.
