When damp, staining, or pressure loss suggests a hidden leak, non-destructive leak detection focuses on identifying the source first, helping avoid guesswork and unnecessary damage.

Leaks can hide in many places. If you’ve noticed any of these problems, our team can help:
Dripping pipes behind tiles, water seeping under trays, damp patches.
Hidden pipes under sinks, dishwashers, or behind cupboards.
Damp rising through floors, soaked walls, or unexplained standing water.
Uneven heating, higher energy bills, or warm floor patches.
A boiler losing pressure is often a sign of a hidden leak.
Water pooling outside or a spike in your bill.
Stains or mould growth with no visible cause.
You can see the damp patch on your ceiling or the bubbling paint on your skirting boards. Perhaps your boiler pressure keeps dropping and your heating system is failing.
You know there is a problem, but you are terrified of what happens next.
A traditional plumber often finds leaks through guesswork.
They start by lifting your hardwood floors or cracking your bathroom tiles to find the source of a leak. This turns your home into a building site before the repair even begins.
We use a different approach.
Our leak detection specialists use advanced technologies to accurately locate leaks without causing unnecessary damage to your property.
We find the exact point of the leak before any floor is lifted or any wall is opened.
Your home stays intact while we do the work.

Traditional leak detection relies on trial and error. If a pipe is buried under a tiled floor, a standard plumber may have to excavate large areas just to find the pipework. This process is slow and expensive.
Our technicians can pinpoint the location of hidden water leaks to within a few centimetres. We use non-destructive detection methods that allow for faster repairs and minimise the impact on your daily life. We protect your assets, from engineered oak flooring to expensive bathroom stone.
We only access the pipe once we know exactly where the leak is.
We use data from acoustic sensors and thermal imaging cameras.
We prevent further structural damage by identifying the source quickly and efficiently.
We use cutting-edge technology to identify leaks that are invisible to the naked eye. These tools allow us to look through solid surfaces without disturbing them.
Thermography allows us to see heat patterns behind your walls. We use infrared cameras to track the spread of moisture and locate the exact point where hot or cold water is escaping.
Leaking water creates a specific frequency of noise. We use a sensitive microphone and acoustic sensors to listen through concrete and timber floors. This allows us to accurately pinpoint the leak rate and the pipe location.
For very small leaks or leaks in a sealed heating system, we use tracer gas. We pressurise the pipework with a safe, inert gas. We then use a sensitive gas detector to find where the gas escapes through the floor. This is one of the most effective leak testing methods for hidden pipework.
We use a moisture meter to map the damp (structural) spread. This helps our leak detection specialists understand the direction of the water flow and narrow down the search area.
In Northern Ireland, many home insurance policies include a clause called Trace and Access. This cover is designed to pay for the cost of finding a leak and exposing the pipework for repair.
Non-destructive leak detection is a professional service. Because we provide a full digital report with photos and data, insurers often accept this as part of a Trace and Access claim. This means you can often claim back the cost of our leak detection work from your provider.
We provide the evidence you need to satisfy your insurance company. Our report documents the detection process, the techniques used, and the most efficient path for the repair.
Northern Ireland homes often face specific plumbing issues related to high-pressure heating systems. Most homes here are unmetered, so you will not see a high water bill. Instead, look for these physical signs.
If you have to top up your heating system every few days, you have a leak in your pipework.
Stains on the ceiling or moisture at the base of your walls.
Unexplained heat on a ground floor can indicate a leaking hot water pipe under the screed.
A persistent damp smell often indicates hidden water pooling under floorboards.
We speak with you to understand the symptoms and the layout of your home or business.
