How Professional Leak Detection Works
Modern leak detection uses specialist equipment to find leaks without invasive work. Here are the main methods used by professionals in the Exmouth area.
Thermal Imaging
Infrared cameras detect temperature differences behind walls and under floors caused by escaping water. This non-invasive method pinpoints leaks without any drilling or digging, making it ideal for finished rooms and tiled bathrooms.
Acoustic Detection
Specialist listening equipment amplifies the sound of water escaping from pressurised pipes. Even tiny leaks deep within walls or underground produce a distinct acoustic signature that trained engineers can locate precisely.
Moisture Mapping
Moisture meters and hygrometers map the extent of damp caused by a leak. This helps establish where water has spread, what materials are affected and whether structural drying is needed after repair.
Pressure Testing
Isolating sections of your plumbing and monitoring pressure drop confirms whether a leak exists and narrows down which pipe run is affected. This is often the first step before pinpointing the exact location.
Tracer Gas Detection
A safe, inert gas is introduced into the pipework. The gas escapes through any crack or hole and is detected at the surface using sensitive equipment, even through concrete slabs and thick walls.
Pipe Camera Inspection
A small waterproof camera is fed into the pipework to visually inspect the interior for cracks, corrosion, joint failures and blockages. Useful for drainage systems and larger supply pipes.
Why Use Professional Leak Detection?
You might be tempted to start investigating yourself, but professional detection saves time, money and damage to your property.
Non-Invasive
Modern detection equipment finds leaks without ripping up floors or walls. Most investigations leave your home exactly as they found it.
Fast Results
A professional leak detection survey typically takes 1 to 3 hours. You will know exactly where the leak is and what repair is needed the same day.
Saves Money Long-Term
Finding the precise leak location means targeted repairs rather than exploratory work. You also stop wasting water and prevent further damage to your property.
Insurance Reports
Many leak detection specialists provide a full written report with photos and thermal images, which you can submit directly to your home insurer for an escape of water claim.

What to Expect from a Leak Detection Visit
Knowing what happens during a leak detection survey can help you prepare and know what questions to ask. Here is a typical process.
Initial Assessment
The engineer will discuss your symptoms, check your water meter and inspect visible pipework to understand the likely scope of the problem.
Pressure Test
Sections of your plumbing are isolated and pressure-tested to confirm a leak exists and narrow down which pipe run is affected.
Detection Scan
Using thermal imaging, acoustic equipment or tracer gas, the engineer pinpoints the exact location of the leak — usually to within a few centimetres.
Report & Repair Options
You receive a report showing the leak location with supporting evidence (thermal images, moisture readings). The engineer will explain repair options and provide a quote, or refer you to a plumber if they are a detection-only specialist.
