Are you planning an extension in the St. Helens area? If your new build sits near or over a public sewer, United Utilities will want to see a formal Build-Over Agreement before you break ground. They need to know that your foundations won't crush their pipes, and they won't just take a guess as an answer. We provide the precise mapping, depth measurements (what we call invert levels), and CAD-ready data that architects and water authorities require. We'll handle the technical details, helping your project breeze through the planning stage without any costly delays or back-and-forth emails.

Gone are the days when finding a pipe meant digging up half the driveway. We use a clever bit of kit called a 'Sonde'—a small transmitter we guide through your drains. As it travels, we track the radio signal from the surface with a handheld receiver. This tells us exactly where the pipe is and how deep it's buried, right down to the centimetre. When we combine this with our high-definition CCTV surveys, we don't just see where the drains go; we see what condition they're in too. It's a completely non-invasive way to get a full underground map without lifting a single spade.

Moving house in Rainford is exciting, but you wouldn't buy a car without checking under the bonnet, would you? A standard homebuyer's survey often ignores the stuff you can't see—the drains. Our mapping and locating service gives you a clear picture of exactly what you're inheriting. If there's a hidden collapse or a root infestation under the lawn, you'll want to know before you sign that contract. We've helped many neighbours in St. Helens negotiate repair costs or simply gain the peace of mind that their new home isn't hiding a drainage disaster.
