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 across Sussex 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 covering Sussex, 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 across Sussex, 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.
Professional leak detection in Sussex requires an experienced approach to investigating a diverse range of property types, building ages and plumbing systems. From coastal homes and period cottages to modern housing developments, apartments and commercial premises, every investigation begins by identifying the system responsible before accurately locating the source of the leak.
Sussex combines historic towns, seaside properties, rural villages and expanding residential developments, each presenting different challenges during a leak investigation. Older buildings often conceal original pipework beneath suspended floors or within solid walls, while modern homes may contain complex plumbing and heating systems hidden inside floors, walls and service voids. Every investigation is tailored to the individual property and the symptoms being experienced.
Our engineers investigate leaks throughout Sussex, including internal plumbing systems, central heating systems, underground pipework, incoming mains water supplies and gas installations. By accurately identifying which system is responsible before repairs begin, we help minimise unnecessary disruption and ensure work is targeted at the actual source of the problem.
We carry out leak detection throughout Sussex, including areas such as Brighton, Hastings, Eastbourne, Crawley and Worthing, as well as surrounding towns and villages across the county.
Sussex is divided into East Sussex and West Sussex, each with its own dedicated county pages covering the towns and areas we serve. If you’re looking for leak detection in a specific part of the county, you can explore our Leak Detection East Sussex and Leak Detection West Sussex pages for more local information.
Every leak investigation begins with a symptom, but the cause is not always immediately obvious. 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, property owners already know which system is affected but need the precise source locating before repairs can begin. It’s also common for customers to contact us after another contractor has confirmed there’s a leak but has been unable to identify exactly where it’s coming from.
Our engineers investigate residential and commercial leak problems across Sussex, establishing which system is responsible before accurately locating the source. By confirming the cause first, we can recommend the most appropriate repair while helping to avoid unnecessary disruption and costly guesswork.
What Are You Seeing?
Every leak starts with a symptom, but the same symptom can have several different causes. If you recognise one of the situations below, our professional leak investigation can establish exactly what is happening before any repair work begins.
A leak where the source is not yet clear
Water coming through a ceiling
Leaking shower or wet room
Boiler losing pressure
Damp patches or mould
Unexpectedly high water bills
Wet garden or driveway
Low water pressure
The sound of running water when taps are off
Signs of a leak beneath a concrete floor
How We Investigate Leaks
Every leak investigation begins with understanding the symptoms and assessing the affected areas of the property. Because water, gas and pressure can travel through buildings and pipe systems, the visible signs of a leak are not always located where the problem originates.
Our engineers carry out a structured investigation, using the most appropriate non-invasive methods to identify the system responsible and accurately locate the source before any repair work begins.
Every investigation is designed to:
Confirm whether a leak is present.
Identify the system responsible.
Accurately locate the source of the leak.
Recommend the most appropriate repair.
Minimise unnecessary disruption to your property.
By confirming the leak location first, repairs can be targeted at the actual fault rather than the symptoms it creates.
Not sure what’s causing the issue? Our engineers can review the symptoms and advise on the best next step.
Every leak investigation is different, so we select the most appropriate methods for the property, the symptoms and the system being investigated. Rather than relying on a single technique, we combine our experience with specialist equipment to accurately identify the source of the leak before recommending any repair work.
Depending on the investigation, this may include:
Acoustic leak detection
Tracer gas detection
Thermal imaging
Moisture mapping
Pressure testing
Camera inspection
Visual inspection and system testing
Using the right combination of methods allows us to locate leaks accurately while helping to avoid unnecessary damage to walls, floors, ceilings and external surfaces.
