Blocked Sewer in South of Wales

A blocked sewer is one of the most serious and unpleasant drainage problems you can face. The foul smells, risk of wastewater backing up into your home or garden, and the general disruption it causes can be incredibly stressful. At Drain King, we understand the urgency. We are your local, experienced drainage engineers, ready to tackle blocked sewer problems for homes and businesses across South Wales, from Cardiff to Swansea and throughout the Valleys.

This is a common question. Generally, you are responsible for the drains that serve your property within your property boundary. The lateral drain, which is the pipe that carries wastewater away from your property and may be shared with neighbours, is usually the responsibility of the local water authority (like Dŵr Cymru Welsh Water). If you're unsure, our engineers can perform a CCTV survey and drain trace to identify the location of the problem and help establish responsibility.

Absolutely. In the vast majority of cases, we can clear even the most severe blockages using our high-pressure water jetting equipment. If the pipe is damaged, we also offer "no-dig" repair solutions like drain relining. Excavation is always a last resort, but if it is needed, our team has the experience to do the job efficiently and with minimal disruption.

As a local South Wales company, we offer a rapid response across our entire service area. We aim for a same-day service, especially for emergencies like a blocked sewer. When you call us, you speak directly to our team, not a call centre, and we will dispatch an engineer to your property as quickly as possible.

A CCTV drain survey provides a clear, live video feed from inside your sewer pipe. It allows our engineers to identify the exact cause of the problem, whether it's a simple build-up of waste, tree root ingress, a cracked pipe, or a complete collapse. This diagnostic work is vital for planning the most effective and cost-efficient repairs.
