Reasons to contact WOW1 2 3 4 5
Common reasons customers contact WOW
High water bills or meter movement when outlets are closed
A damp ceiling below a bathroom
Foul smells from a waste, soil or drainage system
Recurring drainage problems requiring a CCTV survey
How faults are narrowed down
Different faults require different tests
An intermittent or very slow fault may require monitoring, repeat operation or staged isolation before a reliable source area can be supported.
The place where damage becomes visible may not be the source because water can track along pipework, joists, insulation & service openings.
The relevant system is isolated or operated while moisture mapping, thermal imaging, acoustic listening, tracer gas, dye testing or a boroscope is selected only where that method can provide useful evidence.

What happens during a leak investigation in Hackney
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.

Specialist leak detectionFor an intermittent leak that is absent during inspection, WOW begins with a visual inspection, symptom history, moisture mapping & thermal imaging. Each possible water source is then checked separately through isolation, pressure or controlled use. Acoustic equipment, tracer gas, dye, CCTV or a boroscope is selected according to the system, & results are compared before access or repair is recommended.Drainage investigationWaste & soil systems are checked during relevant fixture use using observation, flow, dye or CCTV where suitable.Heating & hot waterHeating circuits may require monitoring or staged isolation when pressure falls without an obvious discharge or accessible leak.

Questions answered
Hackney leak detection FAQs
How would WOW investigate an intermittent leak that is absent during inspection in Hackney?
We establish when the moisture returns & whether it follows use of the repaired fixture or another service. Moisture mapping, repeat operation & separate testing of nearby supply, heating & waste routes can show whether the original leak remains active or a different source is involved.
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 Hackney?
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.
What happens before targeted access is recommended?
WOW compares the visible damage with the route of nearby supply, heating, hot water, waste & drainage services. The relevant system is then isolated, monitored or operated using suitable diagnostic equipment. Targeted access is recommended only when the combined evidence supports a particular pipe route, connection or source area; opening up may still be required for final confirmation & repair.
