What's the cost to clean and seal shower grout in Dubai?« Back to Previous Page

The grout between the tiles in our master bathroom shower has been getting these black spots over the last couple of months, and no matter how much I scrub with bleach, it keeps coming back. We’re in an older villa in Al Quoz, and I'm worried the humidity is making it worse. I’m trying to decide if I should just keep tackling it myself or finally call a professional. For a standard-sized bathroom shower, what’s the average cost in Dubai to get this professionally cleaned and the grout properly sealed?

Recurring black mould in shower grout is a very common issue in Dubai, especially in older villas in areas like Al Quoz. The high humidity and constant air conditioning use create a perfect environment for it to thrive. Bleach only removes surface discoloration but doesn't kill the root structure embedded deep within the porous grout.

For a standard-sized shower, professional cleaning and sealing typically ranges from AED 400 to AED 800. The final cost depends on the square footage of tiled area, the extent of mould penetration, and the type of sealing product used. A proper service should include a high-temperature steam clean to kill the mould at its root, application of an anti-microbial coating, and finally, a high-quality sealant to prevent future moisture penetration.

Given that it's a persistent issue, a professional approach is more cost-effective long-term than repeated DIY attempts. In many cases, if the mould recurs this aggressively, there might be a hidden moisture issue behind the tiles that only an inspection can identify. For a science-backed diagnosis, a company with its own microbiology lab can test a swab sample to identify the mould species and its potential health risks, which guides the correct remediation method.
