How trace & access is approached
Visible water damage can be remote from its source because moisture may track along pipework, joists, insulation or service openings. Moisture mapping & thermal observations are compared with the nearby supply, heating, fixture & waste routes before the relevant system is tested.
Leakage from a waste, soil pipe or fixture connection normally appears while water is being discharged. The relevant fixture is operated & accessible joints are observed, with dye, flow testing or CCTV used where those methods suit the suspected route.

What happens during a leak investigation in Barnet
Confirm the symptom
We establish where water has been noticed or whether the boiler or sealed heating circuit is losing pressure, when the problem occurs & which fixtures or systems are operating at the time.
Map the affected area
Accessible components are inspected & moisture meter readings are used to map the spread. A thermal camera may identify temperature patterns, but thermal imaging is not treated as proof on its own.
Separate possible sources
Cold water supplies, hot water services, sealed heating circuits, fixtures, wastes, drainage & condensate routes are considered separately. Pressure loss refers only to the sealed heating circuit; hot water services are checked for leakage or performance faults.
Test the relevant system
Depending on the evidence, checks may include meter monitoring, staged isolation, pressure testing of suitable supply pipework or a sealed heating circuit, controlled fixture use, dye testing or CCTV inspection. Ordinary drainage is tested during discharge, not as a pressurised service.
Narrow the source area
Acoustic listening equipment, tracer gas & boroscope inspection may be introduced where the pipework & conditions suit those methods. No single instrument reading is relied upon without supporting evidence.
Explain the findings
The results are compared & explained, including any limitations. Targeted access is recommended only where the evidence supports a particular route or source area, & repair or access work is quoted separately.
Relevant services
Services relevant to these symptoms
Specialist leak detectionWe first establish when water loss on a long concealed internal pipe route occurs, then map the affected area with a moisture meter & thermal camera. Supply, sealed heating, fixture & drainage routes are eliminated in sequence by isolation or controlled operation. Pressure testing, acoustic listening, tracer gas, dye testing, CCTV or a boroscope is then used only where suitable, with the combined evidence guiding any targeted access.Heating & hot waterHeating circuits may be isolated or monitored when pressure drops without an obvious discharge point.Plumbing repairsFollowing diagnosis, repairs can be assessed for pipework, valves, wastes, toilets, taps & shower connections.

Questions answered
Barnet leak detection FAQs
How would WOW investigate water loss on a long concealed internal pipe route in Barnet?
The visible moisture pattern is mapped first & compared with the concealed supply, heating, waste & fixture routes nearby. The relevant system is then isolated or operated, with thermal imaging, moisture readings, acoustic listening, tracer gas, dye testing or a boroscope selected only where suitable.
How long does a leak detection survey usually take?
Please allow approximately 2–3 hours on site for a complete leak detection survey, including up to 2 hours of pressure testing where appropriate. The time varies with the number of systems requiring checks, available isolation points & whether the fault occurs during the visit. Very slow or intermittent losses may require monitoring, staged isolation or a further agreed test before a reliable location can be confirmed.
How much does leak detection cost in Barnet?
A complete leak detection survey is £500 + VAT from 8am–5pm, £600 + VAT from 5pm–9pm & £700 + VAT after 9pm. Tracer gas is included where required. Repair or access work outside the survey is quoted separately.
What happens if WOW cannot find the leak?
WOW's No Find, No Fee policy applies where a genuine active leak is within the agreed investigation but its source cannot be identified during that investigation. Terms apply. Rising damp, condensation, building defects & other non leak causes are excluded because the specialist testing has still been completed. Where evidence is limited or the fault is intermittent, the findings & the most appropriate next step will be explained without claiming an unsupported location.
Will floors, walls or ceilings need to be opened?
Not automatically. The objective is to narrow the source before opening a surface. If the combined test results support a particular pipe route, fitting or source area, targeted access may be recommended for confirmation & repair. Excavation, access work, repairs, materials, waste removal & reinstatement are not included in the survey price & are quoted separately before work proceeds.
How does WOW decide which leak detection test to use?
The reported symptom is first matched to the system that could produce it. Suitable supply pipework & sealed heating circuits may require isolation or pressure testing; only a sealed heating circuit is described as losing system pressure. Hot water services are checked for leakage or performance faults, while wastes & drainage are operated & observed during discharge. Thermal imaging, moisture mapping, acoustic listening, tracer gas, dye testing, CCTV or a boroscope are then selected only where they can provide relevant evidence.
