Fast, Accurate Location of Underground and External Leaks
Locating underground and external leaks requires specialist techniques, and our team is equipped with the advanced technology needed to find the source quickly and accurately. We use acoustic listening, tracer gas, ground microphones and pressure testing to pinpoint leaks without unnecessary excavation. This approach ensures a precise diagnosis while keeping disruption to a minimum.
Whether the leak is beneath soil, paving, driveways or external pipework, we work methodically to identify the issue safely and efficiently. Early detection prevents further damage, reduces repair costs and protects both residential and commercial properties from long-term structural problems. Our aim at Complete Solutions is to deliver clarity, speed and reliable results every time.

Non-Invasive Technology for Water Mains Detection
Non-invasive technology plays a crucial role in detecting water mains leaks safely and efficiently. Instead of resorting to disruptive digging or guesswork, we use advanced methods such as acoustic listening devices, tracer gas, thermal imaging and specialist ground microphones. These tools allow us to locate leaks beneath driveways, gardens and external areas without causing unnecessary excavation or damage to your property.
By combining this technology with the expertise of our trained engineers, we can pinpoint the source of a water mains leak with exceptional accuracy. This approach not only saves time but also keeps repair costs lower, ensuring you receive a clear diagnosis and practical guidance on the most effective next steps.

Signs You May Have a Water Mains Leak
Water mains leaks can be difficult to spot because the pipework is often buried underground, but there are several signs that may indicate a developing issue. Unexplained increases in water bills, damp areas in gardens, pooling water outside or patches of ground that remain wet even in dry weather are common indicators. You may also notice reduced water pressure or consistent air in your taps, both of which suggest a possible underground leak.
More subtle signs include the sound of running water when no appliances are in use, cracks appearing in paving or driveways, or unusually lush patches of grass where water is escaping below the surface. These symptoms should never be ignored, as water mains leaks can cause significant structural damage if left untreated. Professional detection ensures the problem is located quickly and repaired before it escalates.

Frequently Asked Questions
We use specialised, non-invasive technology designed specifically for underground leak detection. Acoustic listening devices, tracer gas, ground microphones and moisture mapping allow us to pinpoint the source of a leak without excavation. These tools help us follow the sound, pressure or movement of escaping water along buried pipework. By combining technology with expert assessment, we can locate the exact problem area quickly and accurately. This approach avoids unnecessary digging and ensures you receive a clear, reliable diagnosis before any repair work begins.
An untreated water mains leak can lead to significant and often costly damage. Water escaping underground may erode soil, undermine driveways, damage foundations and cause flooding in outdoor areas. Over time, you might also face higher water bills due to continuous loss of water. If the leak worsens, it can lead to sudden bursts, which cause more severe damage and require urgent repairs. Detecting and addressing the issue early helps protect your property, maintain water pressure and prevent long-term structural concerns.
Yes, Complete Heating & Plumbing Solutions can investigate leaks on both private supply pipes and shared sections of mains pipework. Our engineers assess the layout of your system to identify whether the leak is on your property or part of a shared connection. Using non-invasive detection methods, we locate the issue accurately and clearly explain who is responsible for arranging the repair. This ensures you understand your options and can move forward with confidence, whether the repair is handled privately or via your water provider.
Most water mains leak detection appointments take between one and two hours, depending on the length of pipework and the complexity of the leak. Our non-invasive methods allow us to narrow down the problem quickly, even when the leak is deep underground or hidden beneath hard surfaces. If multiple leaks or system issues are suspected, the process may take longer, but we keep you informed throughout. Our priority is to provide a thorough and accurate diagnosis so the correct repair can be arranged efficiently.
