COMMON CAUSES

What Causes Blocked Drains in Barnet

Blockages build up gradually before they cause a full stoppage — these are the causes our engineers see most often across Barnet’s mix of flats, semis and period homes.

Fat, Oil & Food Waste

The most common cause of kitchen blockages, especially in Whetstone and North Finchley’s flats and conversions.

Wipes & Sanitary Products

Even “flushable” wipes don’t break down and are a leading cause of toilet and downstream blockages.

Tree Root Intrusion

Common in Mill Hill and High Barnet’s leafier streets, where roots can crack and enter older clay drain pipes.

Ageing or Damaged Pipework

Original drainage in High Barnet and East Finchley’s period terraces 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 Barnet

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, 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 roots, damage, or a collapsed section.

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 full external drain blockage, matched to your Barnet property.

Internal Drain Clearance

FAQs

Blocked Drains in Barnet — Questions Answered

Most blocked drain callouts across Barnet are resolved the same day you call, across all postcodes EN5, N20, NW7, N3, N12 and N2.
Internal drain clearance starts from £89, external or manhole clearance from £125, and a full CCTV drain survey with written report is £165. High-pressure jetting is quoted separately after assessment where needed.
Recurring blockages usually point to an underlying cause — tree root intrusion, a damaged or collapsed section of pipe, or a persistent build-up of fat and debris at one point in the system. A CCTV survey identifies the exact cause so it can be properly addressed.
A CCTV survey uses a waterproof camera to inspect the inside of your drainage system, identifying blockages, damage or root ingress without digging speculatively. It's particularly useful if you've had repeated blockages in the same area.
Yes. We cover the entire Barnet borough — High Barnet, Whetstone, Mill Hill, Finchley Central, North Finchley and East Finchley — postcodes EN5, N20, NW7, N3, N12 and N2.
For a single slow-draining sink, a plunger or a mix of hot water and washing-up liquid can sometimes help. Avoid chemical drain unblockers where water is already backed up, as they can react unpredictably with standing water. If the problem persists or affects multiple fixtures, it's best to book a proper clearance.
Turn off your water at the stopcock, switch off your boiler if the leak is nearby, open cold taps to drain remaining water, and take photos for insurance. See the full guide above.
