5 signs you've got a hidden water leak

Hidden leaks are the worst kind — they damage your home for weeks before you notice. Watch for these five signs.

1. Water bill suddenly higher than usual with no obvious change in use.

2. The sound of running water when nothing is on.

3. Damp patches, peeling paint or mould on walls or ceilings.

4. Warm spots on the floor (a hot water pipe leaking under the slab).

5. Lush, green patches on the lawn while the rest is dry.

Modern leak detection is non-invasive — we use thermal cameras and acoustic listening gear so we don't have to smash walls or dig up floors to find the source.
