Start with the affected water system
A suspected supply leak is checked by confirming that known outlets & appliances that use water are closed or isolated before meter behaviour is assessed. If continuing water loss is supported, the supply route can be narrowed using suitable isolation, pressure, acoustic or tracer gas methods.
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 Theydon Bois
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. We assess heating pressure loss separately from changes in mains pressure or flow, & check hot water pipework 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. Drainage checks focus on discharge, flow & accessible connections.
Narrow the source area
Acoustic listening equipment, tracer gas & borescope 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 detectionWe first establish when suspected underground supply pipe leakage 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 borescope is then used only where suitable, with the combined evidence guiding any targeted access.Plumbing repairsUrgent leaks & everyday plumbing faults are assessed with costs explained before additional work is undertaken.Drainage investigationDrainage checks focus on fixture discharge, accessible connections & available inspection points.

Questions answered
Theydon Bois leak detection FAQs
How would WOW investigate suspected underground supply pipe leakage in Theydon Bois?
All known outlets & appliances that use water are first checked or isolated before the meter is monitored. If continuing water use is supported, accessible isolation points, pressure testing, acoustic listening or tracer gas may be used to narrow the affected supply route.
How long does a leak detection survey usually take?
Some leaks can be located within a few hours; others may take several days of investigation, depending on the system, how often the leak occurs & the time needed to isolate & test sections. We explain the approach & agree the charging arrangement before proceeding. View Terms & Conditions
How much does leak detection cost in Theydon Bois?
Hourly leak detection is £100/hr + VAT from 8am to 5pm, £125/hr + VAT from 5pm to 9pm & £150/hr + VAT after 9pm. Alternatively, a complete leak detection survey is £450 + VAT from 8am to 5pm, £550 + VAT from 5pm to 9pm & £650 + VAT after 9pm. Pressure testing, tracer gas analysis, moisture meter testing, thermal imaging, acoustic detection, dye testing & borescope inspection are included in the fixed price leak detection survey where appropriate. CCTV surveys of drainage pipes, power flushing & moling are charged separately. The price is agreed before work begins. 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 fixed price or hourly 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.
