Are you planning on building over or near a public sewer? If so, United Utilities will likely ask you for a Build-Over Agreement. They won't just take your word for where the pipes are; they need professional proof. This is where our drain mapping service becomes your best friend. We don't just find the pipes; we identify the 'invert level' (the depth) and the direction of flow. This data is vital for your architect to draw up accurate CAD plans. By getting us in early, you're not just ticking a box for the council; you're protecting yourself from the nightmare of accidentally piling through a main sewer line halfway through your build.

Nobody wants their driveway or lawn ripped up just to find a single pipe. We use a bit of 'drain magic'—specifically, radio-frequency sondes. These are small transmitters we've attached to our CCTV cameras. As we push the camera through your drains, we can track it from the surface with a handheld receiver. It's incredibly accurate, often down to the centimetre. This non-invasive 'no-dig' approach means we can pinpoint exactly where a lateral drain joins the main sewer or find a hidden manhole that’s been paved over years ago. It’s clean, fast, and saves you a fortune in unnecessary excavation costs.

Buying a new home is stressful enough without inheriting a collapsed drain hidden under a patio. While a standard homebuyer survey looks at the walls and roof, it rarely looks at what's underneath. We've seen plenty of new homeowners in Sefton get caught out by shared drainage issues they didn't know existed. Our mapping and CCTV surveys give you an 'underground blueprint' of the property. If there's an intrusive tree root or a cracked pipe, we'll find it before you sign the contract. It gives you the evidence you need to ask the seller for repairs or a price reduction, providing real peace of mind before you move in.
