Cost to professionally clean and re-grout 15sqm Dubai bathroom?« Back to Previous Page

That black grout is a common issue in Dubai bathrooms due to the high humidity and hard water. In many cases, it's not just surface dirt but a deep-seated microbial growth within the porous grout itself.

For a 15 sqm bathroom, the cost for professional cleaning and re-grouting is highly variable. It depends on the tile material, the extent of the damage, and whether a full re-grout or a deep clean and seal is sufficient. You should expect to request quotes from several licensed contractors for an accurate assessment.

A professional service is often worth it for this specific problem. DIY scrubbing can etch and damage grout, making it more porous and prone to future issues. Professionals use commercial-grade, tile-safe antimicrobial cleaners and steam systems that penetrate deeply. The critical step they provide is applying a high-quality sealant after cleaning, which is essential in our climate to prevent rapid recurrence from the constant humidity and airborne dust.

If the discoloration persists after a thorough professional clean, the grout may be compromised and require complete removal and replacement to fully resolve the moisture and mold issue. For a long-term solution, especially with family health in mind, the investment in proper remediation and sealing is typically more effective than repeated DIY attempts.
