Leak Detection Specialists in London

What Is Leak Detection?

A water leak detection service is where the source of a leak and its location is determined. This is achieved through the use of a range of different tools and techniques by our in-house team.

With hundreds of successful emergency leak detection projects under our belt, our team not only detect water leaks but can also implement a temporary repair for you to prevent any further water damage.

Is Leak Detection Necessary?

Plumbers can repair and restore the most visible leaks without a delay however, if the leak isn’t visible and is hidden within your system, then seeking the help of water leak detection specialists is the best option.

Your property should have a water leak detection service every other year to help prevent problematic plumbing leaks and save you from costly repairs further down the line.

How We Can Help

Using our IRATA-trained abseilers to physically access the side of your building, specialist leak detection equipment and with hundreds of successful leak detection projects under our belt, you’re in safe hands.

How We Trace A Leak

The first step in the leak detection process is a visual assessment of the site.  Once we have located the affected area, we then send out our abseiling team to access, inspect and repair it.

Our IRATA-certified operatives create a minimal disruption service - with no need for erecting loud and costly scaffolding.

We also provide portable anchorage, so there’s no need to worry whether or not your property has a safety system; our team come fully supplied for every situation. If you're looking for a water leak detector in London. We have it all covered.

Here are some of the tools and techniques that we use:

Thermal Imaging Camera

This infrared camera converts the area's data into an image reflecting the surface temperature, which allows us to identify the temperature differences in your pipes.

Moisture Testing

Moisture testing is an internal test that measures whether or not there’s an increase in moisture readings in the area being inspected. This assists us in tracing where there is water ingress and finding the source of the ceiling leak detection.

Borescope Inspection

This optical tool helps assist in a visual inspection of drains, pipes and wiring without needing to remove walls and ceilings. The camera on this instrument allows us to carefully navigate into places that would be impossible to see otherwise. This allows us to spot any small internal cracks, blockages or misaligned piping without having to lift up flooring or remove large areas of a wall.

Water Testing

This is where water is deployed to targeted areas to test whether the waterproofing system is working effectively, this is usually done on the roof of the property. Areas are isolated to provide accurate results of this ‘replicate leak’ detection method.

Drain CCTV Inspection

CCTV equipment is a great tool for detecting leaks in pipes and drainage systems. This camera survey helps to determine whether there’s a failure in the downpipes or if it's a blockage.

Dye Testing

A dye test is a colour test that tracks the route of the potential source of the leak. The colour is completely washable and doesn't leave any sort of staining. This test is carried out in a leaking pipe and would show immediately where the failed joint(s) are.

The Advantages Of Using Us

Some other leak detection companies may investigate the problem from a distance or purely rely on technology and not human eyes when assessing the site.

However, our team physically accesses the affected area, whether that be a pipe, gas or general water leak.

Rope Access

Our rope access trained and experienced leak detection engineers can be hands-on and as close to the problem as possible; other issues on your property may also be detected for you and highlighted to you in the report at the end.

Temporary Repairs

If our teams can resolve the issue upon first inspection they will carry out the final leak repair there and then. You will not have to wait for a report to be written and for another call-out charge. We understand this can be very frustrating for you. If our leak detection specialists need to come back to complete the repair they will at least ensure you have a temporary repair in place to stop the problem from getting worse.


Our fully detailed reports of the completed works give you peace of mind and assure you that your problem has been fully reversed.

Frequently Asked Questions

How can you tell if you have a hidden water leak?

You can detect hidden water leaks from the following signs:

How do I find out where a leak is coming from?

Monitor your water meter closely

You can use your water meter to determine whether the leaks coming from inside or outside your property, by following the next few steps:

Visually Check For Abnormalities

You can locate a leak sometimes with just your eyes. Keep an eye out for bubbling or flaking of walls or stains, as these are usually a sign of a leak coming from behind the wall.

How does leak detection work?

Our specialist team provide a leak detection service following three crucial steps.

Assess - a visual inspection of the problem area is assessed and a plan of action is then decided.

Inspect - our roofing abseilers are then sent to the site, bringing their expert knowledge and the relevant leak detection tool required for finding the source of your leak.

Repair - we then implement a temporary repair, so there’s no need for two call-outs.

What are the different methods of leak detection?

There are a variety of different ways to detect a leak, for example, a common tool that can detect a leak in a pipe is dye testing. This is a colour test that tracks the route of the potential source of the leak.

What is the best leak detection method?

There isn’t necessarily a ‘best’ leak detection method, as the method used is based on each individual problem and location.

Once these factors are assessed, the most suitable method and tool are decided upon.

It’s also crucial that these leak detection tools are paired with specialist knowledge so that the results are as accurate as possible.

Leak Detection in Barking

This property needed emergency leak detection and repair services ASAP.
We offer a 24/7 call out service so if you notice a leak over Christmas, we're still on hand.

The leak was 6 storeys up, there was a busy nearby road, a narrow public path below and the client was left with minimal access options.

They had considered everything, even hiring a helicopter!

But thanks to our abseiling team, we resolved the access problems and repaired the leak without a helicopter or extensive scaffolding.

We had to remove the 80 kg panels to expose the down pipe believed to be causing the issue.

We did this by descending with a separate 3:1 pulley line to support the manual handling of the panels once removed.

The team attached additional supports with slings around the cladding panels and manoeuvred them safely to the ground using the pulley system that helps distribute the weight.

The same technicians that handled the cladding panels also saw to the leak investigation, finding and repairing the misaligned downpipe.

For a team that can handle anything,
