Emergency Drain Unblocking in London South
Blocked drains can happen at the worst possible time, often causing unpleasant smells, overflowing toilets, or even flooding. That’s why we offer emergency drain unblocking services across South London 24 hours a day. When you call our team, we’ll send a drainage engineer to your location as quickly as possible, ready to assess the situation and clear the blockage without delay.
Our emergency call-out service is designed to give you peace of mind during a drainage emergency. Whether you’re experiencing a minor sink issue or a serious sewer overflow, we’ll resolve the issue safely, efficiently, and with minimal disruption.

High Pressure Water Jetting and Drain Clearance
For stubborn drain blockages caused by grease, fat, silt, or other debris, we use high-pressure water jetting to clear your drainage system. This powerful and effective method blasts away blockages and cleans the inside of your pipes, restoring full flow without the need for harsh chemicals or invasive techniques.
High pressure jetting is suitable for both internal and external drains, and it’s one of the most cost-effective ways to clear a blocked drain. Our drain clearance service ensures your drainage system is left clean and functional, helping to prevent further build-up and blockages in the future.
CCTV Drain Surveys and Diagnostics
When a blockage is persistent or its cause is unclear, we carry out a CCTV drain survey. Using advanced camera equipment, our drainage specialists inspect the interior of your pipes in real-time to identify the exact source of the problem.
CCTV drain surveys in London South are ideal for:
- Diagnosing recurring drain issues
- Homebuyers needing drain inspections before purchasing
- Landlords and letting agents maintaining multiple properties
- Commercial properties with large or complex drainage networks
Each survey comes with a full report, including high-resolution footage and professional recommendations for repair or ongoing maintenance.

Drain Repairs and Drain Relining Services
Sometimes a blocked drain is just the symptom of a deeper issue. Cracked or collapsed pipes can lead to leaks, repeated blockages, or structural damage to your property. Clark Drainage offers comprehensive drain repair services in London South, including drain relining, patch repairs, and full excavations where necessary.
Drain relining is a no-dig solution that allows us to repair your pipework without extensive excavation. By installing a resin-coated liner inside your existing pipe, we restore its structure and integrity with minimal disruption. When excavation is unavoidable, our team carries out the work with precision and respect for your property.
Our drain repair service is trusted across commercial and domestic properties in Crawley and throughout the wider London South region.

Drain Cleaning and Regular Maintenance
To prevent drainage emergencies and keep your system in good working order, regular drain cleaning is essential. Our maintenance services help remove the build-up of fat, food, soap, and other debris that commonly causes blocked drains.
We recommend regular drain cleaning for homes, restaurants, commercial kitchens, schools, and large public buildings. It’s an excellent way to avoid unexpected plumbing problems and extend the life of your drainage system. By choosing Clark Drainage for routine maintenance, you’re investing in long-term drainage health and peace of mind.
