Hidden Water Leak? 7 Signs Your Home Has One (and Why You Shouldn’t Wait)

Introduction

A hidden water leak inside a wall, slab or under-floor cavity can quietly destroy a Melbourne home for months before anyone notices. The good news: there are seven signs that almost always show up first.

The 7 signs

### 1. Your water bill jumped without explanation

Compare this quarter to the same quarter last year. A sudden jump of more than 20% with no change in usage is a strong leak signal.

### 2. The water meter moves with everything turned off

Turn off every tap and appliance. Watch the meter for 10 minutes. If the dial moves, water is escaping somewhere.

### 3. Damp patches, peeling paint or mould

Especially low on walls or where walls meet floors. Mould that returns after cleaning is a textbook hidden-leak symptom.

### 4. Warm spots on tiled or concrete floors

A leaking hot water pipe under a slab heats the surface above. Walk around barefoot in the morning — you’ll feel it.

### 5. Unusual sounds in the walls

A faint hissing, dripping or rushing sound when no fixtures are running.

### 6. Lush green patches on the lawn

A small section growing faster and greener than the rest often means a buried supply line is leaking.

### 7. The sound of running water at night

Particularly at night when the house is quiet — this is your home telling you directly.

How professional leak detection actually works

We don’t guess. We use a layered, non-invasive approach:

• Acoustic listening equipment to pinpoint pressurised leaks
• Thermal imaging cameras to see temperature differences through walls and slabs
• Tracer gas testing for leaks that won’t show acoustically
• Pressure testing to confirm the leak is stopped after repair

No smashed walls. No guesswork.

FAQ

Will my insurance cover the damage?

Sudden burst events are usually covered. Gradual leaks often aren’t. Document everything from day one — photos and timestamps.

How fast can you come out?

We prioritise suspected active leaks and aim for same-day or next-day response.
