COMMON CAUSES

What Causes Blocked Drains in the City of London

Blockages build up gradually before they cause a full stoppage — these are the causes our engineers see most often across the Square Mile’s mix of flats and converted buildings.

 

Fat, Oil & Food Waste

The most common cause of kitchen blockages, especially in Barbican and Moorgate's flats.

Wipes & Sanitary Products

Even "flushable" wipes don't break down and are a leading cause of toilet and downstream blockages.

High-Rise Stack Blockages

Shared waste stacks in the City's residential towers can back up and affect multiple flats at once.

Ageing or Damaged Pipework

Original drainage in older converted buildings near St Paul's can collapse or shift over time.

⚠️ Early warning signs of a developing blockage
  • Water draining slower than usual
  • Gurgling sounds from toilets or plugholes
  • Unpleasant smells from drains or plugholes
  • Water backing up when using another appliance
  • Damp patches near external drain covers
  • Multiple fixtures affected at once

THE PROCESS

How We Clear a Blocked Drain in the City of London

A methodical process to clear the blockage and identify the underlying cause, not just a temporary fix.

 

Diagnose the Blockage

We identify whether the blockage is local to one fixture or affecting a wider run or shared stack, and agree a fixed price before starting.

Clear the Blockage

Using rodding, high-pressure jetting or mechanical clearance depending on the type and severity of the blockage.

CCTV Survey if Needed

For recurring blockages, a camera survey identifies the root cause — whether that's damage, a collapsed section, or a build-up point.

Test & Clean Up

A full flow test to confirm the blockage is cleared, with the work area left clean and tidy before we leave.

CAPABILITY

Every Type of Blockage, Cleared

From a single slow sink to a shared stack blockage in a high-rise, matched to your property.
