A blocked drain in London isn’t just an inconvenience—it is a severe health hazard, a threat to property hygiene, and a potential cause of costly business downtime. At Cargate Engineering, we provide professional, rapid-response emergency drain unblocking across Greater London 24 hours a day, 365 days a year.

Whether you are managing an overflowing commercial sewer line in Central London or dealing with a severely blocked stack pipe in a residential block, our qualified engineers and fleet of specialist Jet Vac tankers are on standby to restore full flow to your system.

What Constitutes a Drainage Emergency?

While minor slow drainage can often be scheduled for routine maintenance, certain situations require an immediate, professional emergency response to prevent flooding and structural damage:

Overflowing Toilets & Stack Pipes: Sewage backing up into commercial washrooms or domestic properties.
Multiple Fixture Backups: Sinks, showers, and gullies surcharging simultaneously—a clear indicator of a main sewer line blockage.
External Flooding & Surcharging Gullies: Water pooling around outside drain covers, basement lightwells, or car parks.
Foul Odours & Health Risks: Strong sewage smells entering living or working spaces, indicating trapped waste or structural pipe failure.
Commercial Kitchen Blockages: Heavy grease and fat accumulation threatening operations and hygiene compliance.

Our London Emergency Drainage Services

We do not just poke at a blockage with rods; we deploy advanced engineering equipment to clear the obstruction completely and restore your pipework to optimal capacity:

Commercial & Domestic Clearance: Unblocking everything from stubborn domestic soil pipes to high-volume municipal and industrial sewer connections.
High-Pressure Water Jetting: Slicing through compacted silt, heavy fatbergs, scale, and stubborn debris to thoroughly clean the internal pipe walls.
Emergency CCTV Drain Surveys: Deploying robotic camera technology to immediately identify the root cause of recurring blockages, collapsed sections, or root ingress without disruptive digging.
Gully Cleaning & Flood Pumping: Rapid removal of standing water, silt, and waste from surcharged gullies, basements, and interceptors using our high-capacity vacuum tankers.
Grease Trap & Fatberg Clearance: Fast emergency support for London hospitality venues and commercial kitchens affected by fat and grease build-up.
