Leak Detection in Barnet and Hadley Wood
From the large houses of Hadley Wood to the Victorian streets of High Barnet and New Barnet, we trace leaks with tracer gas and thermal imaging before anything is opened.

Leaks in Barnet and Hadley Wood homes
Hadley Wood is a private estate of big detached houses with long supply pipes, underfloor heating and several bathrooms. High Barnet, New Barnet and Arkley range from Victorian terraces near the church to 1930s semis and post-war estates, and Cockfosters and East Barnet add flats and maisonettes with shared services.
In Hadley Wood we traced a kitchen leak using the tracer gas detector. With the system charged with gas, the detector gave a clear reading at one point in the kitchen and the leak was confirmed there without opening the rest of the floor. That is the routine across EN4 and EN5: confirm with a pressure test, locate with tracer gas or thermal imaging, then open the smallest area.
Parking is easy on the estate roads and mostly unrestricted elsewhere. Our report with photographs and readings supports a trace and access claim on your buildings insurance.

What we detect in Barnet and Hadley Wood

Water leak detection
Hidden leaks behind walls, under floors and in ceilings, pinpointed with thermal, acoustic and tracer gas kit before anything is opened up.
Water leaks
Tracer gas leak detection
A safe hydrogen and nitrogen mix is put into the drained pipe, rises through the floor or wall and is picked up by the detector directly above the leak.
Tracer gas
Underfloor heating leak detection
A leaking underfloor heating loop is found by isolating circuits at the manifold, then mapping the pipes with thermal imaging and tracer gas.
Underfloor heating
Central heating leak detection
A boiler that keeps dropping pressure means water is escaping somewhere in the heating circuit. We find the pipe or fitting and fix it.
Heating leaks
Trace and access insurance reports
Leak detection carried out and documented the way insurers expect, with a report your claims handler can act on straight away.
Insurance reportsFrom your first call to a leak you can see in the report
Call or WhatsApp with a few photos and a line about the symptoms. We ask a handful of questions, agree a fixed price and book the survey, usually for the same or the next day.
On arrival we pressure test the mains, hot water and heating, check the meter and test the escaping water, so we know what we are looking for before the detection starts.
Thermal imaging, the acoustic ground microphone and tracer gas are used as the pipework dictates until the leak is marked on the floor or wall.
You get a written report with readings, thermal images and photographs, ready for a trace and access claim. If you want the leak fixed, we open that one spot and repair it.
Leaks in Barnet and Hadley Wood: questions answered
Do you cover High Barnet, New Barnet and Cockfosters?
Yes. EN4 and EN5 including High Barnet, New Barnet, Arkley, Hadley Wood, Cockfosters and East Barnet.
Can you find a leak under fitted kitchen units?
Yes. Tracer gas and thermal imaging read through plinths and floor finishes, so we can locate the leak before deciding whether a unit needs to come out.
How quickly can you get to Barnet?
Same or next working day in most cases.
Do you handle large houses with underfloor heating?
Yes. Each loop is tested at the manifold and mapped with the thermal camera to find the faulty one and the leak point within it.
