Who We Are

Pinpointing Problems: Cardiff CCTV Drain Survey Specialists

Take the guesswork out of your drainage issues with our state-of-the-art CCTV drain inspections. Serving Cardiff and Caerdydd, we use flexible fibre-optic cameras to navigate deep into your pipework, giving us a crystal-clear, real-time view of your drain's condition. This non-invasive diagnostic tool helps us accurately locate and identify the exact cause of any issue, from cracks and fractures to collapsed sections, stubborn blockages, invasive root ingress, or even pest intrusion. Whether you need a Homebuyer Drain Survey before purchasing a property in Cardiff, a Build-Over Survey for your extension (compliant with Dŵr Cymru Welsh Water standards), or an Insurance Report to support a claim, we provide detailed Wincan reports and clear explanations. Our team can also perform drain mapping and tracing to understand your system layout.

Lasting Drain Repairs with Minimal Disruption in Cardiff

Discovering a damaged or collapsed drain doesn't always mean extensive excavation that disrupts your Cardiff property. Drain King specialises in modern, non-invasive "no-dig" drain repair solutions. For localised damage like cracks or holes, we expertly use patch lining (resin patch repairs). This involves inserting a resin-impregnated fibreglass patch into the pipe and curing it in place, creating a strong, permanent seal. For longer sections of damaged pipe, our full drain relining service creates a tough new pipe within the old one. These trenchless technologies are cost-effective, faster, and cause far less disruption compared to traditional excavation. Of course, for severely collapsed drains that demand it, we also provide expert excavation and precise pipe replacement services, always ensuring a lasting repair done right.
