Who is responsible for black mold in my shower grout?« Back to Previous Page

Recurring black mould in shower grout is a maintenance issue, but responsibility depends on its severity and cause. Surface mould from high humidity is typically a tenant's cleaning responsibility. However, if the grout is porous, cracked, or the underlying sealant has failed, allowing moisture into the wall, it becomes a structural issue the landlord must address.

Under Dubai rental law (RERA), landlords are responsible for repairs to the property's structure, including fixing issues with waterproofing that lead to persistent dampness. Your JLT apartment's extreme humidity exacerbates the problem, but the root cause is often failing grout or sealant. Document your repeated cleaning attempts and notify your landlord in writing, requesting they repair the deteriorating grout to prevent water ingress.

For immediate management, use a vinegar or diluted bleach solution and improve ventilation by running the bathroom exhaust fan for 30 minutes after showering. A professional inspection can determine if the issue is superficial or requires regrouting, which is the landlord's obligation if the wall's integrity is compromised.
