Local Experts for Local Infrastructure
South East London presents unique challenges for drainage systems. The Victorian clay pipe infrastructure common in SE6, SE13, and SE10 areas is highly susceptible to ground movement and tree root ingress. According to Thames Water, over 300,000 drain blockages are reported across London annually, with a disproportionate number in older Victorian-era properties. Furthermore, properties within Thames Water sewer adoption areas often face confusion over who is responsible for the blockage.
The attending engineers understand the dense London clay soil and how it affects older drainage networks. They arrive equipped with the right tools to diagnose and clear the blockage swiftly, ensuring your property is protected from water damage.
Blocked Drain vs. Collapsed Drain — How to Tell the Difference
Symptoms of a Blockage
- Slow draining sinks or baths
- Gurgling sounds from plug holes
- Foul smells around drains
- Toilet water level rising when flushed
Usually resolved same-day with rodding or high-pressure jetting. Typical cost: £80-£180.
Symptoms of a Collapse
- Recurring blockages that clear briefly then return
- Visible subsidence or sinkholes in the garden/driveway
- Damp patches or localized flooding
- Rodent infestations
Requires a CCTV survey to diagnose, followed by structural repair. According to RICS, drainage defects are among the most commonly missed issues in standard homebuyer surveys.
Our Emergency Process
When you call us for an emergency, here's exactly what happens:

- Same-day attendance: A same-day response is requested across SE London where one is available.
- Assessment: We inspect the drain to locate the blockage and identify its nature. We use CCTV cameras if needed to see inside the pipe.
- Fixed Quote: A transparent, fixed price with no callout fee from the attending engineer. The price is approved before work starts.
