How Does Our Leak Investigation Service Work?

Our nationwide detailed moisture surveys use various detection methods to find your leak and develop a suitable way to restore your property after the water damage, including:

Moisture Mapping

Almost every surface will hold some moisture, but we use moisture mapping to identify those surfaces that have an unusual amount on and in them, caused by a leak. This can involve drawing an outline around the wet area to see if it increases or decreases over time.

Thermal Imagery

Thermal cameras measure the infra-red light being output by various hot things and it is represented on a screen, which allows us to detect hot and cold leaks where they are affecting the temperature.

On-site Salts Analysis

Testing for salts is a great way to determine whether the cause of the issue is rising damp and will lead to further investigations.

Void and Pipe Work CCTV Inspection

Where possible, we will use a loose floorboard or other entry point to use Closed-Circuit Television cameras to find the source of a leak and examine areas that cannot be seen without more destructive methods of leak investigation.

Acoustic Surveys

Leaks make noises that can be heard by specialised microphones and programmes that will filter out the sounds of everyday life to give a more accurate representation of where a leak is.

Tracer Gas Leak Detection Methods

We use a food-grade, safe gas with our detectors to pinpoint leaks in heating systems. This method is used particularly in large commercial properties with complex systems.

System Pressurisation Tests

Just like a tyre with a puncture, a system with a leak will not be able to hold its pressure levels and is a great way to test if there is in fact a leak. If you have a complex system, it may be possible to pressurise different parts at different times to more accurately pinpoint the leak.

Water Chemical Analysis & Comparisons

Determining the type of water that is leaking can help to diagnose the source of the leak. This will involve a sample being sent away for testing, so other methods are preferable where they are quicker.

Dye Testing

We introduce a water-soluble dye that is not toxic to the system, which can be used for visual inspections to find leaks and making water currents visible, where they are escaping from seals and membranes.

Leak Investigation Services In Commercial & Domestic Environments

Operating in both the Commercial and Domestic environments, we recognise each bring challenges and more importantly, their own disruption to everyday lives and business operations.

Within the Domestic arena, we recognise our services can be settled through Household Insurance Policies that have Trace & Access cover applying. We advise all customers of this possibility prior to commencing any investigation.

Within the commercial sector we can provide a detailed quotation for our investigations and align any works to minimise potential business disruption.
