Cost to professionally clean and reseal moldy bathroom tile?« Back to Previous Page

For a Jumeirah villa bathroom, the cost for professional cleaning and resealing depends heavily on the extent of the mold growth and the square meterage of tiling. You can expect a range from a few hundred for a straightforward clean and seal on a small area to significantly more if the grout requires extensive removal and replacement. Always request an on-site assessment for an accurate quote; any company giving a firm price without seeing the job may not be thorough.

Given Dubai's high humidity and the persistent slimy texture you describe, this is likely more than surface mold. That black, slimy growth is often Stachybotrys, which can penetrate deep into the porous grout. DIY cleaners typically only bleach the surface, leaving the root structure intact, so the mold will return within weeks. A professional service will use industrial-grade, EPA-approved biocides to kill the root system, then strip and reapply a high-quality sealant designed to withstand the local climate.

It is absolutely worth hiring a professional in this case. The initial investment prevents recurring mold problems, protects your tile substrate from damage, and addresses the underlying moisture issue. For a permanent solution, also ensure your bathroom's exhaust fan is functioning correctly and run it for at least 30 minutes after each shower to manage the humidity that causes this.
