Leak Detection in Earlsfield and Wandsworth
In Earlsfield the tracer gas detector at an inspection chamber found a water main leak under a paved drive, saving the owner from digging up the lot.

Leaks in Earlsfield and Wandsworth homes
Earlsfield, Southfields, Wandsworth and Battersea are Victorian terraces with paved front gardens, side returns and loft conversions, alongside newer riverside apartments. Supply pipes run under the paving from the road, and the terraces have long copper heating runs added under floors in the 1970s.
On an SW18 job the inspection chamber lid came off, the tracer gas detector sampled at the chamber and along the paving, and the leak on the water main was placed within a small area. A single excavation followed at that spot rather than a trench across the drive. Inside the terraces we use thermal imaging and tracer gas for heating leaks and dye testing for bathrooms.
Parking is controlled on almost every road and we plan around it. The report includes readings, photographs and the extent of damage for a trace and access claim and for any conversation with Thames Water.

What we detect in Earlsfield and Wandsworth

Water mains and underground leak detection
Leaking supply pipes under driveways, gardens and concrete floors, located with acoustic and tracer gas kit so only one small excavation is needed.
Mains & underground
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
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
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.

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.
