Trace and Access Leak Detection

Our leak detectors use a range of methods to reliably find the source of a leak anywhere in a property. They all have years of experience in relevant trades, including plumbers, gas engineers, roofers and drainage engineers. It means we can find and repair any leak, and reinstate water damaged areas to their original condition.

The non-invasive equipment used to trace a leak doesn’t cause damage to your property. Most insurance companies insist on the use of trace and access methods when they’re processing an “escape of water” claim.

All the information needed for a successful insurance claim comes in a detailed report provided following every investigation.

Our trace and access leak detection service is available 24/7 and we don’t charge extra for an emergency attendance, when we aim to have a leak detector on-site within an hour.

WATCH: How we detect leaks

Most trace and access companies use similar methods. There isn’t one method that’s used to locate any type of leak. Normally, several techniques are used on each job. Results from each technique allows attention to be focused in a specific area.

We’ve produced a series of videos to show examples of how the trace and access approach used in different situations.

This video shows some of the techniques used when the source of damp could be either plumbing pipes or a roof.

How to find a water leak

Borescope cameras

These flexible cameras allow our experts to look inside tight or closed spaces, such as a boiler cupboard or behind a washing machine with restricted access. They can be easily inserted into ceiling voids via light fittings. Small holes might need to be drilled in walls to investigate cavity space. However, they can be filled without difficulty afterwards to avoid damage to your home.

Providing our experts with visual evidence, they’re a useful and less damaging option to a fully invasive visual inspection. Images from the camera are saved and included as part of the survey report.

Dye / flow tests

Fluorescent dyes are a method for visually tracing water leaks. They’re visible to the eye, but by using a UV lamp they can be seen in very low concentrations. This means they can highlight the position of a leak before droplets of water begin to form.

The water soluble dyes are added to pipes before water is released in them. Different dyes are available depending on the pipework being tested. For example, a specialist food dye that’s non-toxic is used when testing water supply pipes. Other dyes are available for wastewater and soil pipes or heating system pipes.

Flood testing

This test attempts to replicate the movement of water through a point of ingress to where it becomes visible inside a property as water damage. Water is released where it would normally be expected to drain away. A moisture meter and thermal image camera are used to help track whether or not water is penetrating building fabric rather than draining away. Small areas are tested systematically to help pinpoint the problem area.

Flood tests can be conducted using either hot or cold water. They are useful for helping to detect ineffective seals around baths and showers and well as glass roofs. Faults in brickwork and masonry can also be detected with this trace and access method.

Pressure testing

Detecting a drop in pressure on a closed plumbing system is a quick and obvious indication of a leak. Our experts will fit a pressure gauge on parts of a plumbing or heating system that can be easily isolated. For example, pressure testing an underfloor heating system separately from the main central heating system can help to focus the investigation to a smaller area.

This basic method can only indicate the presence of a leak. Other detection methods are needed to help trace the location of the it.
