In Whitley Bay properties, hidden leaks often trace back to undocumented supply pipe alterations in edwardian seafront properties converted into multiple flats or pipe joints disturbed by sandy coastal soil movement near the promenade. Watch for a higher water bill, damp or warm patches on the floor, a hissing sound near pipework, or lower water pressure. Properties such as Edwardian seafront properties converted to flats, inter-war semis, and modern housing are worth checking often, since a leak can run for weeks before it shows.
