Leak Detection in Stockwell and Clapham
A Stockwell job used a pressure test, the acoustic detector and a water sample test strip to prove which system was leaking before anything was opened.

Leaks in Stockwell and Clapham homes
Stockwell, Clapham, Brixton and Vauxhall are Victorian and Georgian terraces divided into flats, council estates from every post-war decade, and new towers along the river. Pipework is shared, stacked and often unmapped, and the first job is usually to prove which system the water is coming from.
In SW9 we started with gauges on the system to confirm a pressure loss, took the acoustic detector along the pipe runs where it peaked at 295 over the leak, and used a test strip on the escaping water to tell mains water from heating water. The tracer gas detector at an outside drain checked the buried section. The report named the system, the location and the cause.
Parking is controlled everywhere and we plan for it. Reports are written for trace and access claims and for managing agents who need responsibility between flats settled.

What we detect in Stockwell and Clapham

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
Acoustic leak detection
A ground microphone listens for the sound of water escaping under pressure through floors, concrete and paving, and the reading peaks directly over the leak.
Acoustic
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 reports
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 gasFrom 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 Stockwell and Clapham: questions answered
Do you cover Brixton, Vauxhall and Clapham North?
Yes. SW9, SW4 and SW8 including Stockwell, Clapham, Brixton, Vauxhall and Oval.
How do you tell whether the water is from the mains, the heating or the drains?
A test strip on a sample of the escaping water shows the difference, and pressure tests on each system confirm it. The report states which system is at fault.
Can you survey a council or housing association flat?
Yes, with the leaseholder's or landlord's agreement. The report is written so the responsible party is clear.
How soon can you get to Stockwell?
Usually the next working day.
