Matching the test to when water appears
Where water passes between rooms, floors or occupancies, the visible damage may not identify the source. Accessible supply, heating, fixture & waste routes are considered separately & operated or isolated where possible.
The test method is selected for the affected system rather than the position of the visible mark. Individual readings are treated as supporting evidence & targeted access is recommended only where the combined findings support a particular route or source area.

What happens during a leak investigation in Walthamstow
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.

The right specialist for the system involved
Specialist leak detectionWe first establish when damp spreading between flats or adjoining rooms 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.Commercial mechanicalCommercial investigations focus on the reported mechanical or water system, using suitable isolation, pressure, flow, moisture or thermal checks where appropriate.HVAC & air conditioningHVAC faults are assessed according to the equipment & reported symptoms, including condensate drainage & connected components where these fall within scope.

Questions answered
Walthamstow leak detection FAQs
How would WOW investigate damp spreading between flats or adjoining rooms in Walthamstow?
The accessible supply, heating, waste & fixture routes are considered separately. Isolation, controlled fixture use & moisture mapping are used where possible so water passing between rooms or occupancies is not attributed to the wrong service.
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 Walthamstow?
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 are supply, heating & drainage leaks distinguished?
Each system behaves differently. A supply leak may show continued meter movement or loss during isolation; a sealed heating fault may cause pressure loss; a waste or drainage leak normally appears when a fixture discharges. WOW tests the relevant systems separately & compares those results with moisture & temperature patterns before reaching a conclusion.
