Drain Unblocking and CCTV in Barnet
Your Local Drainage Team in Barnet
High Barnet, New Barnet, Arkley and Hadley, along the A1000. We work across High Barnet and Chipping Barnet High Street, New Barnet, East Barnet, Arkley and Hadley, in the London Borough of Barnet's area (EN4 and EN5). The main routes in are the A1000, the A1 and the A411, with the M25 at junction 23. We come across from Watford on the A411 and A1, so give us the postcode and we will give you a realistic window.
Most Barnet calls are a blocked drain, so drain unblocking comes first. If it recurs, a CCTV survey shows why, and no-dig drain repair fixes the pipe.
Why Barnet Calls Drain 247
From High Barnet and Chipping Barnet High Street to Hadley, Barnet is regular work for us.
On the Ground in Barnet
High Barnet and Chipping Barnet High Street, New Barnet, East Barnet, Arkley and Hadley. We come across from Watford on the A411 and A1, so give us the postcode and we will give you a realistic window.
Honest About the Clock
Tell us the postcode. Same-day in Barnet is usual; we will give you a realistic arrival window from Watford rather than pretending we are round the corner.
Quoted Before We Roll
A fixed price before we set off for Barnet. No call-out fee, and the same rate at 3am as at 3pm.
Camera Before We Guess
Repeat blockage? We put a camera down and show you the footage before quoting anything else.
The Pipes Under This Patch
This town sits on Victorian laterals, 1930s clay, and fat and scale on the high-street runs. Each of those fails in its own way, so the first job is finding out which one you have.
Repair Without Digging First
No-dig first: patch lining or CIPP, with excavation only when the camera shows lining will not restore the pipe.
Book Drainage Work in Barnet
Tell us the street in Barnet and what the drain is doing. We will say which plant to send (van, camera or tanker), give an honest window and fix the price before anyone sets off.
Most of Barnet is EN4 and EN5, in the London Borough of Barnet's area. We also cover the places around it, including Potters Bar, Edgware and Enfield.
What We Do in Barnet
Quoted as the job actually is in Barnet — not as a package you do not need.
Unblocking
Toilets, sinks, gullies, manholes and outdoor drains in Barnet. Most domestic blockages are cleared on the first visit.
CCTV Surveys
If it keeps coming back, we camera the line. You get the footage and a report you can act on — or show a buyer, insurer or building control.
Jetting
High-pressure water that scours fat, silt and scale off the wall, not a hole punched through a blockage that will reform.
No-Dig Repair
Cracked or displaced clay lined from inside. The drive, patio or frontage in Barnet stays put where the pipe can take a liner.
Mapping
Scaled plans and invert levels before you apply. Say if the architect asked for a drawing rather than a condition survey.
Tanker Work
Interceptors, cesspits, flood extraction and volume that a van cannot take. “Fine last winter” is usually scale. We camera when it has happened before rather than charging you for the same clearance twice.
The Drains Under Barnet
Under Barnet you find Victorian laterals, 1930s clay, and fat and scale on the high-street runs. Which of those you have decides the job. A camera tells us whether it is fat, roots, scale or a broken length, and from that, which method fits.
For recurring trouble we film the run and show you the footage. Cracks and displaced joints are usually a no-dig repair: a patch liner or a full CIPP sleeve.
“Fine last winter” is usually scale. We camera when it has happened before rather than charging you for the same clearance twice.
CCTV Drain Survey in Barnet
Our CCTV drain survey in Barnet starts from £180. We film the run from the property to the sewer connection and point out roots, cracks, displaced joints or fat build-up.
Under Barnet that usually means Victorian laterals, 1930s clay, and fat and scale on the high-street runs. The survey tells you which is which before anyone talks about digging.
How a Visit in Barnet Works
A real person on the phone, a price before we roll, then the job that the drain actually needs.
-
You Call
A real person answers. Describe the postcode and the symptom. We tell you the likely cause and the right plant.
-
Fixed Price Agreed
The figure is agreed before anyone sets off. It does not change because it is Sunday or because the job took longer than the first look suggested — unless you then ask for a separate repair.
-
We Diagnose and Clear
Rods, jetting or a cutting head for a blockage. A camera if it has happened before. Lining only when the footage shows why.
-
You Get the Record
If we surveyed, you keep the footage. If we only cleared, you know what we found. Either way you are not guessing next winter.

Common Questions About Drainage in Barnet
Do You Cover Barnet?

How Quickly Can You Get to Barnet?

Do You Charge a Call-Out Fee in Barnet?

Who Is Responsible for the Drain in Barnet — Me or the Water Company?
The public sewer in Barnet belongs to Thames Water. Pipework from your house to that sewer is usually yours. It is not always obvious where that line falls. A camera survey settles it, and we will tell you honestly if the blockage is one you should not be paying for.
Will You Need to Dig Up the Garden or Driveway in Barnet?
Rarely. We line from the inside where the pipe allows, and only recommend excavation in Barnet when the survey shows lining will not work.
The Drain in Barnet Keeps Blocking. What Then?
We stop rodding and film it. Under Barnet there is Victorian laterals, 1930s clay, and fat and scale on the high-street runs, and a recurring blockage there normally points to a fault you can see on camera. You get the footage and a separate repair quote.
Do You Cover Both High Barnet and New Barnet?
Yes. We are based in Watford and cover Barnet (EN4 and EN5) for unblocking, CCTV, jetting, lining and tanker work, including High Barnet and Chipping Barnet High Street, New Barnet and East Barnet.
