Leak Detection in Isleworth and Hounslow
In Isleworth we confirmed a leak at a pipe chase in a wall with the tracer gas detector, the same method we use across Hounslow, Osterley and Spring Grove.

Leaks in Isleworth and Hounslow homes
Isleworth, Spring Grove and Osterley have Victorian and Edwardian houses near the river and the 1930s semis of the Great West Road estates, while Hounslow adds post-war housing and newer flats. The older houses have pipe chases cut into solid brick walls where copper sits against lime plaster and slowly corrodes.
In Spring Grove the tracer gas detector gave a strong reading at a chase in a wall, confirming the leak point so the plaster was opened in one place. Across TW3, TW4 and TW7 we combine a pressure test, thermal imaging to follow the pipe runs and tracer gas to pinpoint, then moisture readings to show how far the water has spread.
Parking is controlled near the stations and easier elsewhere. The report sets out cause, location and damage with photographs and readings for a trace and access claim.

What we detect in Isleworth and Hounslow

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
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
Thermal imaging leak surveys
A thermal imaging camera shows warm pipe runs and cool wet patches through floors and walls, so the leak is seen before anything is opened.
Thermal imaging
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 Isleworth and Hounslow: questions answered
Do you cover Osterley, Brentford and Hounslow West?
Yes. TW3, TW4 and TW7 including Isleworth, Spring Grove, Osterley, Hounslow, Hounslow West and Brentford.
How do you find a leak in a pipe buried in a brick wall?
Tracer gas escapes from the leak and comes through the plaster, and the detector reads it at the surface. Thermal imaging shows the pipe run so we know where to look.
How soon can you get to Isleworth?
Usually the next working day.
Will you tell me how far the damp has spread?
Yes. Moisture readings around the leak are included in the report so the making good can be scoped properly.
