Central Heating Leak Detection
Locating hidden heating system leaks without unnecessary disruption.
A hidden central heating leak can cause your boiler to repeatedly lose pressure, leave damp patches around your home and result in costly property damage. At Maystone Leak Detection, our experienced engineers use specialist equipment to locate leaks within central heating pipes, radiators and underfloor heating systems, even when they're concealed beneath floors or behind walls.
Using a combination of advanced leak detection technologies, we help identify the source of the problem without unnecessary disruption, allowing repairs to be targeted accurately.

What is central heating system leak detection?
Central heating leak detection is the process of locating hidden leaks within a heating system without relying on visible signs of damage.
Leaks can occur within pipes, joints, radiators, valves or underfloor heating circuits and are often difficult to locate because much of the system is hidden beneath floors or behind walls.
Using specialist equipment and years of experience, our engineers identify the source of the leak so repairs can be targeted accurately.
Signs you may have a central heating leak
-
A common sign that water is escaping somewhere within the heating system.
-
Frequent pressure drops can indicate a hidden leak.
-
Water may be escaping behind walls or beneath floors.
-
A leaking system may affect efficiency.
-
Could indicate an issue within the heating circuit.
-
Hidden leaks often require specialist detection.
Common causes of central heating leaks:
What causes central heating system leaks?
Corroded pipework
Failed fittings
Damaged underground pipework
Faulty valves
Radiator connections
Underfloor heating pipes
Ageing heating systems
How does Maystone detect central heating leaks?
Finding a central heating leak requires more than simply looking for visible water. Our engineers begin with a detailed assessment of your heating system and symptoms before selecting the most appropriate detection methods.
Our leak detection methods include:
Thermal Imaging ↗
Identifying temperature changes caused by escaping water.
Acoustic Detection ↗
Listening for sounds created by leaks within pipework.
Tracer Gas ↗
Helping locate difficult-to-find leaks within sealed systems.
Moisture Mapping ↗
Assessing areas affected by hidden moisture.

Why we combine technologies
At Maystone Leak Detection, we understand that every leak is different, which is why we never rely on a single detection method in isolation. While each technology has its own strengths, combining multiple techniques allows our engineers to build a clearer picture of what is happening within your property.
By comparing the results from advanced technologies such as thermal imaging, acoustic listening, moisture mapping, tracer gas testing and other specialist methods, we can accurately confirm the source of a leak before recommending any repairs.
This approach helps us provide a more accurate diagnosis, reduce unnecessary disruption and ensure the right solution is used for your specific situation.

FAQs about central heating leak detection:
-
A boiler that repeatedly loses pressure is often a sign of a leak somewhere within your central heating system. While some pressure loss can be caused by faulty components, hidden leaks in pipework, radiators or underfloor heating systems are a common cause. Our engineers use specialist leak detection equipment to locate the source without unnecessary disruption.
-
Yes. Many central heating leaks occur beneath floors, behind walls or within ceilings, making them difficult to spot. You may notice symptoms such as low boiler pressure, damp patches or the need to regularly top up your heating system, even though no visible leak can be seen.
-
At Maystone Leak Detection, we use a combination of advanced technologies to accurately locate hidden heating system leaks. Depending on the property and the type of leak, this may include thermal imaging, acoustic listening, tracer gas testing, moisture mapping and pipe correlation. By combining multiple methods, we can accurately confirm the source of the leak while minimising disruption.
-
In most cases, yes. Our non-invasive leak detection techniques are designed to locate hidden leaks without the need for unnecessary lifting of floors or opening walls. Once we've identified the source of the leak, any repair work can be focused on the exact location, helping to minimise disruption and reduce repair costs.
-
The cost of central heating leak detection depends on factors such as the size of the property, the complexity of the heating system and the technologies required to investigate the leak. Please get in touch with our team for a tailored quotation based on your specific situation.
-
Not always. Many leak detection methods can be carried out while the system remains operational. However, in some cases, draining part or all of the heating system may be necessary to carry out certain tests safely and accurately. Our engineers will explain the process before any work begins.
-
Yes. Hidden leaks beneath concrete floors are a common issue within central heating systems. Our engineers use specialist leak detection technologies, including acoustic listening, tracer gas testing and thermal imaging, to accurately locate leaks beneath solid floors while avoiding unnecessary excavation wherever possible.
-
Not necessarily. In many cases, only a small section of pipework or a single component is leaking. Our aim is to accurately locate the source of the problem so repairs can be targeted to the affected area, avoiding unnecessary replacement of the entire heating system wherever possible.
