Underground Water Leak Detection Specialists
Unexpected high water bills? Low pressure? Water meter spinning when nothing is being used? GC Maintenance are specialists in underground water leak detection across Kent and South East London.
Underground Water Leak Detection Specialists
We use specialist leak detection methods to locate hidden leaks on underground water mains and supply pipes with minimal disruption wherever possible.
Whether the issue is beneath a driveway, garden, pathway, garage floor or inside the property, we can identify the source of the leak and advise on the most cost-effective repair solution.
Advice is based on the condition of the existing supply, access, and whether repair or full replacement makes better long-term sense.

Signs You May Have a Hidden Water Leak
If left unresolved, underground leaks can worsen over time and potentially damage surrounding ground, driveways and foundations.
Our Leak Detection Methods
Tracer Gas Leak Detection
A specialist tracer gas is introduced into the pipework and detected at ground level to help accurately pinpoint underground leaks.
Acoustic Leak Detection
Using sensitive listening equipment, we can often hear leaks beneath the ground without excavation.
Pressure Testing
We isolate sections of pipework to determine whether the water main or internal plumbing is responsible for the water loss.
Water Meter Testing
We carry out live meter tests to confirm whether water is passing through the supply when no fixtures are being used.
We use targeted investigation methods first so unnecessary excavation is avoided wherever possible.
Repair or Replace?
In some cases, a localised repair is possible. However, older lead or heavily deteriorated water mains are often beyond economical repair.
Where appropriate, we may recommend full water main replacement, moling installation, upgrading from lead to modern MDPE pipe, or increasing pipe size for improved pressure and flow.
We will always explain the options clearly before works proceed.
