Trace & Access Leak Detection 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.

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

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.

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.

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.

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.
