Sewer Repairs in South of Wales

This is one of the most common questions, and the answer depends on where the problem is located. In simple terms, you are responsible for the drains that serve only your property, right up to the point they connect with the public sewer. These are often called private drains or lateral drains. The larger public sewers, which are shared with other properties, are the responsibility of the local water authority, such as Dŵr Cymru Welsh Water.
It can be very difficult to know where the boundary is. Our advanced CCTV drain surveys are the perfect tool to find the exact location of the blockage or damage. This allows us to determine who is responsible for the repair work, giving you a clear answer and peace of mind.

Not necessarily. We know the last thing any customer wants is major disruption and excavation work on their property. That's why we specialise in advanced "no-dig" or "trenchless" repair technology. For many issues, like cracks, fractures, or root damage, we can repair the pipe from the inside.
We use methods like drain relining, which creates a brand new, tough pipe inside the old one, and patch repairs for smaller, localised damage. These services are faster, less disruptive, and often more cost-effective than a full excavation. Of course, if the pipe has completely collapsed, digging may be the only option, but we will always assess this fully and discuss every option with you first.

We take the guesswork out of drainage problems. Before any repair work begins, we carry out a detailed CCTV drain survey. We guide a high-definition, flexible camera through your sewer pipe to get a crystal-clear look at its condition in real-time.
This survey shows us exactly what the problem is and where it is. We can identify cracks, collapsed sections, stubborn blockages, or tree root ingress with pinpoint accuracy. This advanced diagnostic work means we can recommend the most effective and efficient repair for your specific needs, saving you time and money.

Over our 30 years in the business, we've seen it all. The most common causes of sewer damage we encounter in South Wales include:

• Tree Root Ingress: Tiny roots can get into pipe joints and expand over time, causing cracks and major blockages.
• Ground Movement: The ground can shift naturally over the years, putting pressure on pipes and causing them to crack or misalign.
• Age and Material: Older clay pipes can become brittle and are more susceptible to fracturing and collapse than modern materials.
• Severe Blockages: A long-term, unresolved blockage can put immense pressure on a pipe, eventually leading to damage.

Our goal is to provide a lasting, quality solution, not a temporary fix. When we use modern drain relining or patch repair techniques, we are essentially creating a new, seamless, and corrosion-resistant pipe within your existing one. These advanced repairs are incredibly strong and are designed to last for many decades, giving you confidence that the problem is solved for good. Every repair we undertake is completed to the highest standard, using the best materials available.

Because every drainage system and every repair job is different, it’s impossible to give a fixed price without first seeing the problem. The final cost depends on factors like the extent of the damage, the repair method needed (e.g., a small patch repair versus a full reline), and the depth and accessibility of the pipe.
What we can promise is complete transparency. Our process starts with a CCTV survey to fully diagnose the issue. Based on those findings, we provide you with a detailed explanation and a clear, no-obligation quote for the required work. With Drain King, there are no hidden charges.
