Specialist Leak Investigation in Redbourn

The equipment is checked while operating, including accessible condensate trays, pumps, connections & drainage routes. This helps distinguish a condensate fault from leakage on an unrelated plumbing or heating service.

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.

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.
