Start with the affected water system
Commercial water or mechanical faults are investigated around the affected service. Accessible pumps, valves, joints & distribution pipework are inspected before suitable isolation, pressure, flow, moisture or thermal checks are selected.
A falling reading on a sealed heating system may be caused by an accessible component, a discharge point or concealed heating pipework. The visible parts of the system are checked before isolation, pressure testing or specialist location methods are considered.

What happens during a leak investigation in Borehamwood
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 leaks within commercial or production areas, 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.Plumbing repairsPlumbing work can include fault finding & repair options for pipework, controls & sanitary fittings once the cause is understood.Drainage investigationWaste & soil systems are tested during use; they are not described as pressurised water services.

Questions answered
Borehamwood leak detection FAQs
How would WOW investigate leaks within commercial or production areas in Borehamwood?
Accessible pumps, valves, joints & distribution pipework are inspected first. Where the system can be safely isolated, suitable pressure, flow, moisture or thermal checks are selected for that service before repair or targeted access is recommended.
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 Borehamwood?
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 is an intermittent leak investigated?
The first step is to identify what changes when the water appears, such as shower use, appliance discharge, heating operation or a period of continued supply use. The suspected system can then be operated repeatedly, monitored or isolated in stages. If the fault does not occur during the visit, the findings & any appropriate next test are explained without claiming an unsupported source.
