Emergency Drain Unblocking and Call-Outs
When you experience a blocked drain, speed matters. Our London North team offers emergency call-outs to deal with drainage problems as quickly as possible. Whether you have water backing up through your toilet, a build-up of debris causing flooding in your kitchen, or an overflowing gutter, our drainage engineers arrive promptly with all the necessary equipment to clear a blocked drain safely and effectively.
Our emergency drain clearance services are available 24/7, including evenings, weekends, and bank holidays. You can rely on us to resolve the issue, no matter the time of day, providing peace of mind when you need it most.
High Pressure Drain Clearance
Blocked drains are typically caused by the build-up of fat, grease, hair, silt, and debris. In some cases, more serious issues like root intrusion or collapsed pipes can be the source of the problem. That’s why we use high pressure water jetting to clear the obstruction and fully clean the interior of the pipe.
This method is extremely effective for removing even the most stubborn blockages without causing any damage to the pipework. Whether it’s inside your home or affecting an external drainage system, our team ensures your drains are completely unblocked and flowing freely.
CCTV Drain Surveys in London North
For persistent drainage problems or to investigate the source of a blockage, we offer detailed CCTV drain surveys. This non-invasive service allows us to view the inside of your pipes in real-time, helping us to locate structural issues, root ingress, misaligned joints, and blockages deep within your system.
After every CCTV drain survey, we provide a comprehensive report complete with video footage and clear recommendations for any required repair work. Our surveys are particularly popular with homebuyers, landlords, and commercial property managers who want to avoid unpleasant surprises down the line.
If you are in London North and need to understand the condition of your drains, our CCTV surveys offer a cost-effective and reliable solution.

Drain Repairs and Drain Relining
Sometimes, clearing a blockage reveals a more serious issue with your drainage system. Cracked or collapsed pipes may require professional repair or replacement. At Clark Drainage, we provide both traditional excavation and no-dig drain relining services to restore your drainage system with minimal disruption.
Drain relining involves inserting a resin-saturated liner into the damaged pipe, which is then cured in place to create a strong, durable new lining. This method is ideal for many domestic and commercial properties and avoids the need for costly and time-consuming excavation.
If excavation is necessary, our trained engineers will carry out the work carefully and cleanly, restoring the area once the job is complete. We aim to deliver fast and effective drainage repairs with as little inconvenience to you as possible.

Residential and Commercial Drainage Solutions
Clark Drainage supports both domestic and commercial properties in London North. For homeowners, we provide clear explanations, fixed pricing, and fast turnaround times. Whether you need to clear a blocked kitchen sink, unblock your toilet, or clean an external drain, we can help.
For commercial properties, we offer tailored drainage maintenance, emergency call-out services, and CCTV drain inspections to keep your premises running safely and efficiently. We work with a wide range of commercial clients, including letting agents, schools, shops, offices, and restaurants.

Regular Maintenance to Prevent Drainage Issues
The best way to avoid emergency call-outs and costly repairs is to maintain your drains regularly. Our maintenance programmes include routine drain cleaning and inspections to keep your system clear and reduce the risk of recurring problems.
Scheduled maintenance is especially beneficial for commercial sites and high-traffic properties that experience greater demand on their drainage system. We’ll design a bespoke plan based on your property’s needs, helping to prevent future drainage emergencies.
