How do we find pipes without digging up your driveway? We use what’s called a 'sonde'—a clever little battery-powered transmitter that we pop into the drain. As it travels through your pipes, we track the radio signal from the surface. This allows us to pinpoint the exact route, the depth (or 'invert level'), and the direction of your drainage system with incredible precision. Combined with our high-definition CCTV survey equipment, we can map out your entire network while also checking for any cracks or root intrusions that might cause trouble down the line.

Are you building over or near a public sewer? If so, United Utilities will likely want to see a professional drainage layout before they give you the green light. Most homeowners we speak to in Lancashire find the paperwork a bit of a headache, but that's where we come in. We provide the detailed CAD-ready plans and condition reports that architects and water authorities actually need. By getting the mapping done early, you can prove your new walls won't put pressure on the pipes, making the whole planning permission process a lot smoother.

Imagine you've just picked up the keys to a lovely terrace in Chorley town centre, only to find out a month later that the main lateral drain is collapsed right under your new conservatory. Standard home surveys often miss what's underground. We regularly help buyers by providing a full 'underground blueprint' before they exchange contracts. It gives you the peace of mind that you aren't inheriting a drainage disaster, and if we do find a fault, you’ve got the evidence you need to negotiate the price or get it fixed before you move in.
