Blocked Drain Unblocking in Cardiff
When a blocked drain begins to cause issues, you want quick relief and zero hassle.

We are experienced in clearing blocked toilets, urinals, showers, and all kinds of drainage pipes for both residential and commercial properties.
CCTV Drain Surveys in Cardiff
Persistent drainage issues often require deeper investigation. Our CCTV drain survey services use the latest closed-circuit television technology and specialist drainage cameras to inspect pipes and sewers. The Clark Drainage team conducts comprehensive surveys to find the source of any drain issue—whether it is a collapsed pipe, root intrusion, broken joint, or hidden debris. Detailed survey reports are supplied for insurance, property purchase, or planned drain repairs. This cutting-edge approach means no guesswork, just accurate solutions and transparent advice.

For more severe damage or collapsed drains, our drain engineers will recommend the most effective and cost-efficient solution. All repairs include a guarantee and expert advice to keep your drainage system in top condition.
High-Pressure Drain Jetting
Drain jetting is one of the most effective solutions for clearing blockages and maintaining healthy pipes. Using specialist equipment, our Cardiff team can blast away stubborn build-ups, grease, scale, and roots, ensuring a deep clean for domestic and commercial drainage systems. This process helps prevent future blockages, reduces odours and ensures free-flowing drains.
Planned Preventative Maintenance
Many drainage issues in Cardiff properties are avoidable with regular care. Our planned preventative maintenance packages are tailored for both residential and commercial sites. By scheduling routine drainage inspections, cleaning, and health checks, you catch small issues before they escalate.
