How much to professionally clean or re-grout bathroom tiles?« Back to Previous Page

The grout between the tiles in our Jumeirah villa's main bathroom has turned almost black with mold, and no matter how much I scrub with bleach, it won't come off. We had a lot of humidity over the last few months and the ventilation isn't great. I'm worried it's a bigger job than I can handle. What's the typical price range for professional grout cleaning or re-grouting for a standard-sized bathroom here?

Professional grout cleaning or re-grouting costs vary significantly based on the extent of the mould infestation and the size of the bathroom. For a standard-sized villa bathroom in Jumeirah, the price is primarily determined by whether the issue is surface-level or has penetrated deeper.

When grout turns black and resists bleach, the mould has often penetrated the porous material, making surface cleaning ineffective. In Dubai's high humidity, this is a common issue exacerbated by poor ventilation and year-round AC use creating constant condensation cycles. A professional assessment is needed to determine if antimicrobial cleaning can salvage the grout or if full removal and re-grouting is required.

Re-grouting is the more comprehensive solution, as it physically removes the contaminated material. This is typically more costly than a deep cleaning service but provides a long-term resolution, especially when paired with improved bathroom ventilation to address the root cause.

For an accurate quote, you should request an on-site inspection from a certified provider. Reputable companies will assess the moisture source, provide a scope of work, and can often supply before-and-after microbial swab results from an independent lab to verify the treatment's efficacy, which is crucial for health concerns.
