This Sliema inspection started with a tenant complaint: water was entering the corridor area of an apartment. The landlord needed to understand whether the problem was inside the unit, coming from above, or linked to shared building drainage.
Thermal Inspection
Thermal imaging identified cold areas from the ceiling, indicating moisture movement from above rather than a surface-only stain.
The same type of issue was visible in the apartment above, so the investigation moved towards the shared drainage and gully areas rather than treating the affected corridor as an isolated problem.
Likely Drainage Path
The likely source was connected to the building gullies. When gullies are blocked, poorly maintained or badly detailed, water can pool and find routes into walls, ceilings and shafts.
Shared blocks need coordinated action. One apartment can see the damage while the actual cause sits in a common area, drainage route or unit above.
Shaft And Mould Conditions
During the inspection, mould was also noted in the building shafts. We avoid making health claims without lab testing, but visible mould in shared shafts should be treated seriously and handled by appropriate cleaning or remediation professionals.
The recommendation was to involve the block administrator so gullies and shaft conditions could be checked and addressed at building level.
If your apartment has ceiling moisture, corridor damp or mould linked to shared services, apartment block leak detection and damp moisture inspection can help identify where responsibility and repair should start.
