Whether you need leak detection for a hidden water leak, a boiler that keeps losing pressure, a water meter that keeps moving or spinning, an unexplained high water bill, damp with no obvious source or signs of a leak beneath a floor, our specialist leak investigation service in Hayes is here to help. We investigate residential and commercial leaks, accurately identifying and locating the source before explaining our findings and, where appropriate, carrying out the necessary leak repair.
The Leak Hunter are leak detection specialists in Hayes, providing water leak detection, central heating leak detection, mains water leak detection, underground leak detection, concrete floor leak detection and, following emergency isolation, gas leak detection. These specialist services support our overall leak investigation process, allowing us to establish which system is responsible before pinpointing the source of the problem.
We also provide Trace & Access leak detection in Hayes, using appropriate non-invasive leak detection methods to locate hidden leaks with minimal unnecessary damage or disruption. Where required, we can provide detailed leak detection reports with findings and supporting evidence for insurance and Trace & Access claims, before recommending or carrying out the appropriate repair.
If damp patches, staining, or unexplained moisture have started appearing inside your home in Hayes (UB3, UB4), it may indicate a leak somewhere within the pipework. Our leak detection specialists carry out controlled testing to locate where water is escaping and confirm the exact source before any repair work begins.
Hayes includes a mix of 1930s semi-detached houses, post-war family homes, and modern residential developments. Plumbing systems altered during kitchen refurbishments, bathroom upgrades, or property extensions can leave pipework concealed beneath floors or inside walls where leaks can be difficult to trace without specialist leak detection equipment.
Our engineers carry out professional investigations across London through our Leak Detection London service, identifying the precise location of leaks before any access or repair work is undertaken. We regularly assist homeowners in Hayes as well as nearby areas including Hillingdon, Southall, and West Drayton when concealed pipework leaks need confirming.

Some leaks are clearly visible, while others remain concealed behind walls, beneath floors, within ceilings, underground or inside pipework that cannot be seen without specialist investigation.
In other cases, the system affected is already known, but the precise escape point still needs locating before repairs can begin. Customers also contact us after another contractor has confirmed a leak but has been unable to identify exactly where it originates.
Our engineers investigate residential and commercial leak problems across Hayes, establishing which system is responsible before accurately locating the source. Confirming the cause first allows the repair to be targeted correctly while helping to avoid unnecessary disruption and costly guesswork.

How We Investigate Leaks
Every leak investigation begins with understanding the symptoms you are experiencing and assessing the property as a whole. Rather than making assumptions, we establish which plumbing or pipe system is responsible before narrowing the investigation to the precise source of the leak.
Depending on the property and the symptoms present, the investigation may involve internal plumbing, central heating systems, underground pipework, incoming mains water supplies, concrete floor pipework or gas installations. Many leaks occur behind walls, beneath floors, within ceilings or below ground, making professional investigation essential before repairs begin.
Every investigation is designed to:
Identify which system is responsible for the leak.
Locate the exact source as accurately as possible.
Minimise unnecessary disruption to the property.
Provide clear findings before any repair work begins.
Recommend the most appropriate repair based on the results of the investigation.
Depending on the findings, we may use a combination of specialist equipment and proven diagnostic techniques to confirm the source before recommending the next steps.

Our Investigation Methods
Every leak is different, so there is no single method that works in every situation. Rather than relying on one piece of equipment, we select the most appropriate combination of techniques based on the type of property, the symptoms being experienced and the plumbing or pipe system being investigated.
Depending on the investigation, we may use one or more of the following methods:
Our Leak Investigation Process
Every investigation begins with understanding the symptoms you are experiencing within the property. Once the affected areas have been identified, we follow a structured diagnostic process designed to confirm the source of the leak.
Acoustic Leak Detection
Sensitive listening equipment detects the sound of escaping water within concealed pipework.
Thermal Imaging
Infrared cameras identify temperature differences caused by moisture or water movement behind surfaces.
Tracer Gas Testing
A safe inert gas can be introduced into pipe systems so that detection equipment can identify where the gas escapes.
Moisture Mapping
Specialist moisture meters measure the spread of moisture within building materials to help narrow down the leak source.
These methods allow us to locate leaks accurately without unnecessary damage to walls, floors, or ceilings.
By combining specialist equipment with over 25 years of practical experience, we can accurately identify the source of many leaks while helping to minimise unnecessary disruption to your property.

Frequently Asked Questions
Do I need to know where the leak is before booking an investigation?
No. Most customers contact us because they know there is a leak but cannot identify the exact source. Our investigation is designed to establish which system is responsible and accurately locate the leak before any repair work begins.
What types of leaks do you investigate?
We investigate a wide range of residential and commercial leaks, including internal plumbing, central heating systems, underground pipework, incoming mains water supplies, concrete floor pipework and gas installations. We begin by identifying which system is responsible before recommending the most appropriate repair.
Will you need to damage my property to find the leak?
Our investigations are designed to minimise unnecessary disruption. We use specialist equipment and proven diagnostic techniques to identify the source of the leak before any access work begins. In many cases, this allows us to avoid unnecessary damage while accurately locating the problem.
Can you repair the leak once it has been found?
Yes. Once we have identified the source of the leak, we’ll explain our findings clearly and advise on the most appropriate repair. Where suitable, we can also carry out the repair work.
How long does a leak investigation take?
Most residential leak investigations are completed during a single visit, although the time required depends on the type of property, the plumbing system involved and the complexity of the investigation.
