Expert Underground Leak Detection Services
Underground leaks are often the most difficult type of leak to identify. Because pipework is buried beneath soil, concrete, or flooring, the source of the problem is rarely visible. Many property owners only realise there is an issue when they receive a high water bill or notice damp patches appearing inside the building. At North East Leak Detection, we provide specialist underground leak detection services designed to locate the exact source without unnecessary digging. Using modern equipment such as acoustic listening devices, tracer gas technology, and thermal imaging, we can trace leaks in mains water pipes, supply pipes, and underground heating systems. Our approach is always non-invasive wherever possible, meaning we avoid disruptive excavation until we are confident about the precise location of the leak. Working across Durham, we understand the mix of older properties and newer developments in the area, and we tailor our methods to suit the type of ground and pipework involved.

Signs You May Have an Underground Water Leak
Underground leaks can remain hidden for weeks or even months, slowly causing damage beneath the surface. One of the most common warning signs is an unexplained increase in your water bill. If your usage has not changed but your charges have risen, it may point to water escaping from an underground pipe. You might also notice damp areas in your garden that never seem to dry, even during warmer weather. In some cases, driveways or paved areas may begin to sink or crack due to water washing away the ground beneath them. Inside the property, reduced water pressure or the sound of running water when all taps are turned off can also indicate a hidden leak. At North East Leak Detection, we take these signs seriously and carry out thorough investigations to confirm the cause. Early detection can prevent structural damage, protect your foundations, and save you money in the long term.


Our Advanced Leak Detection Process
When you contact North East Leak Detection for underground leak detection in Durham, we begin with a detailed conversation about the issues you have noticed. Understanding the history of the problem helps us choose the most effective detection method. Once on site, we carry out a full assessment of the property and surrounding areas. We use specialist acoustic equipment to listen for the sound of water escaping under pressure, even beneath concrete or tarmac. Where necessary, we introduce safe tracer gas into the pipe system, which rises to the surface at the point of the leak, allowing us to identify its location with precision. Thermal imaging can also be used where underground heating systems are involved. Our goal is always to pinpoint the leak before any digging takes place. After identifying the source, we provide a clear report explaining our findings and outlining the recommended next steps, ensuring you fully understand the situation.
