How can checking under bathroom basins for damp patches reveal hidden leaks?

Slow leaks often hide where you don’t look: under basins, inside cabinets, or behind pipes. A small drip that goes unnoticed can soak wood, swell boards, attract termites, or cause dampness in nearby walls.

If you occasionally open the cabinet or look under the basin with a torch and feel around for dampness or see water marks, you can catch these early. A loose nut or worn washer is simple to fix if spotted in time.

Left alone for months, that same leak can mean replacing cabinets, dealing with smell, and even repairing damaged floors or tiles.
