Renovation is the best time to investigate moisture properly. If wet walls are closed up too early, the problem can be hidden until after handover.
In this Sliema project, the architect asked for a leak detection inspection after two garage wall areas were found to be heavily wet. At the same time, the roof pump kept cycling, which suggested that water could be escaping somewhere in the system.
How the leak route was checked
Thermal scanning was used to map the wet zones and confirm the pattern around the garage. The next step was to work from the basement manifold and isolate lines one by one while observing pump behaviour.
When the line feeding the garden was shut, the pump stopped cycling. Because the garden sat above the wet garage walls, that result gave the project team a strong target for repair instead of opening unrelated areas.
What the team needed next
The plumbing contractor was brought in to repair the suspected garden supply issue. Moisture-map findings and a retest plan were left with the team so dry-down could be checked before finishes were closed.
Lesson for Sliema renovations
Wet walls, pump cycling and garden pipework should be treated as a professional inspection problem, not a cosmetic snag. A water leak detection visit before sign-off can save weeks of rework and give architects, owners and contractors a clearer repair route.
