Leak Detection
Professional Leak Detection from licensed plumbers. Upfront pricing. Workmanship guaranteed. Serving the Golden Horseshoe since 1922.
Professional leak detection locates the source of hidden water leaks using pressure testing, acoustic detection equipment, and thermal imaging rather than exploratory demolition. Hidden leaks behind walls, under slabs, or in buried supply lines can cause significant structural damage, mould growth, and elevated water bills for months before becoming visible. Accurate source location before any surface is opened keeps disruption and repair cost to a minimum.
How Our Leak Detection Service Works
A clear, professional process every visit, every customer.
Isolate the System
We isolate sections of the supply system to identify which pipe run is losing pressure, narrowing down the location before any physical investigation begins.
Pressure Testing
Pressure decay testing quantifies the leak rate and confirms whether the source is in the supply line, drain system, or a fixture connection.
Acoustic and Thermal Scan
Acoustic listening equipment detects water movement sound through walls and slabs. Thermal imaging identifies cold or wet zones that indicate leak location.
Confirm the Source
Once the location is identified, we confirm by a targeted inspection of the smallest possible surface area before any repair begins.
Repair and Document
The leak is repaired using appropriate materials for the pipe type and location, and the repair is documented for warranty and insurance purposes.
Benefits of Professional Leak Detection
Finds the Source Before Surfaces Open
Pressure testing, acoustic equipment, and thermal imaging locate the leak precisely. Exploratory demolition without this adds repair scope and cost without adding accuracy.
Minimises Disruption to Your Property
Because we know where the leak is before opening anything, we access only the smallest area necessary. Less disruption means less restoration work after the repair.
Stops Ongoing Water Damage
Every hour a hidden leak continues, it saturates more framing, insulation, and finished material. Fast, accurate detection stops the damage clock.
Prevents Mould and Structural Damage
Moisture behind walls creates mould within 24 to 48 hours and softens structural framing over weeks. Early detection prevents remediation costs that dwarf the detection fee.
Confirms Leak Rate and Location
Pressure decay testing confirms there is a leak, quantifies the rate, and narrows the location before any physical investigation begins.
Appropriate for Slab, Wall, and Underground Leaks
Acoustic and thermal detection equipment works through concrete slabs, finished walls, and buried supply lines, covering all common hidden leak scenarios.
Workmanship Guaranteed
All leak detection and repair work is backed by our full workmanship guarantee. If the source we identified and repaired was incorrect, we return and correct it.
