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.

Recent customer reviews

  • Ricky, Aspect’s leak trace and access plumber couldn’t have been more professional or helpful. Gave great advice, worked swiftly and efficiently to find the hidden leak and kept me well informed before doing the repairs. Highly rated.

    Jo, Ampthill, MK45

  • We had a leak where our insurance allocated plumbers could not easily find the source. We were advised we needed to obtain trace and access services which we could invoice back, so we contacted Aspect. Their tradesman was extremely knowledgeable and was able to run through the process in finding the source to our leak. A few hours later and it was found. I wanted to shout about the fantastic service we have had. Thank you!!

    John, Newmarket, CB8

  • My insurance company wasted a day by not sending a trace and access specialist. When Aspect sent Aaron he efficiently eliminated the possibilities and found the leak and fixed it. Then put together a report for me to submit to my insurer while also arranging for someone to come to repair the damage the leak had caused. I will certainly be working with Aaron and Aspect again.

    Katie, Ingatestone, CM4

  • Luke from Aspect has just completed a trace and access investigation at my property and detected the leak within an hour. He was very thorough and is extremely professional, taking time to explain all options available to rectify the issue. Aspect is definitely a company I would be happy to recommend to anyone.

    Kenny, Huntingdon, PE28

  • Aspect has never let me down. Not the cheapest but they always turn up and deliver. On this occasion some expert leak tracing by Aaron using enough tech kit to launch a spaceship. Really good service and a job well done.

    Matt, Gerrard's Cross, SL9

  • I had a problem in unable to trace a leak from a pipe. Aspect sent Jim along to find the leak. He was very thorough and efficient tackling the investigating. He was very courteous and careful of our home. The job is still ongoing and am confident the problem will be resolved.

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

Trace & Access Leak Detection | Specialist Leak Tracing | Aspect (3)

Thermal imaging

A thermal imaging camera shows surface temperatures without needing access or to insert probes into the structure of a property. Cool areas detected in building fabric can indicate the accumulation of moisture. Readings can help direct attention where it’s needed quickly. It’s probably the most used piece of equipment for trace and access leak detection.

It clearly shows the flow of hot water through pipes even when they’re concealed. It’s commonly used to find central heating leaks. Our experts also use them as part of flood tests to help pinpoint where water is entering a property, or where baths or showers aren’t correctly sealed. High-res images from the camera are included in reports.

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.

Tracer gas

A non-harmful, odourless gas is released under pressure into drained pipes. A highly sensitive detection probe is used to locate where the gas is escaping from. The gas is lighter than air and rises quickly. It can penetrate all types of floor covering, including hardwood, laminate, tiles, carpet and vinyl. It can even penetrate concrete.

As well as being a reliable piece of water pipe leak detection equipment, tracer gas can also be used to find leaks in sections of flat roof. The gas can be released into ceiling voids. The probe is able to trace where it’s escaping through the roof covering.

Tracer gas is frequently utilised to find leaks in heating systems. However, it can’t always be used on water-fed underfloor systems.

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.

Ground microphone

A buried leak, sometimes referred to as a slab leak, can be located to within a few centimetres by using sensitive acoustic equipment. It’s a very reliable piece of equipment for trace and access.

A highly sensitive microphone is placed on the ground. Tiny vibrations, created as water escapes under pressure from the pipe, are amplified as sound. As the microphone is placed in different positions, the changes in sounds detected allows the location of the leak to be pinpointed.

The technology works on small or large leaks in pipework made from any type of material. It’s so sensitive that tiny leaks buried beneath concrete floors can be pinpointed.

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.

Moisture meter

The moisture meters we use are extremely sensitive monitoring devices. They allow our experts to accurately assess moisture levels in building material to a depth of 15mm.

Readings are taken by inserting two probes into the building material (this leaves two small holes where each reading is taken). Results establish the amount of excess moisture that’s present. Multiple readings can show how moisture is spreading through walls or ceilings.

The equipment doesn’t show where the water is coming from, so it can’t be used as a water leak finder. It’s main use is to build a more detailed picture of the problem before the tests to trace a leak begin.

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.
