Water leaks are one of the most common, and costly, issues faced by property owners across the UK. According to Ofwat, in 2023-24 48.8 litres of water has leaked, per person, per day across England and Wales. Whether you’re a homeowner dealing with unexplained damp patches, a landlord responding to tenant complaints, or a commercial property manager concerned about infrastructure integrity, detecting a hidden leak can be a stressful and disruptive process.
This is where a leak detection company becomes essential.
In this article, we’ll explain what a leak detection company does, the specialist techniques they use, and how choosing the right provider like Harmuns Leak Detection can help you resolve the issue efficiently, without unnecessary damage or disruption.
What Does a Leak Detection Company Do?
A leak detection company specialises in identifying the source of water leaks that are not visible or easily accessible. These are typically leaks hidden under floors, behind walls, within ceilings, or buried in outdoor pipework. Unlike general plumbing services, leak detection companies are equipped with advanced, non-invasive tools that allow them to locate even the most elusive leaks without tearing apart your property.
At its core, the mission of a leak detection company is to:
- Accurately locate the leak as quickly and effectively as possible.
- Minimise disruption and cost through non-destructive methods.
While the signs of a leak may vary, such as increased water bills, mould, water stains, or reduced pressure – professional leak detection companies bring clarity to the problem, giving property owners the confidence to take informed action.
Who Uses Leak Detection Services?
Leak detection services are essential across a wide range of sectors:
- Homeowners may notice signs of damp, pooling water, or a musty smell – often with no clear source. A hidden pipe leak may be slowly damaging structural elements or causing health risks due to mould.
- Landlords and letting agents rely on professional detection to swiftly resolve tenant complaints and protect their investment properties without risking further damage.
- Commercial property owners and facilities managers often face more complex infrastructure challenges, such as underground leaks, pressurised systems, or multiple plumbing zones within large buildings. Early detection is critical to avoid business downtime or structural complications.
No matter the setting, time is of the essence – and this is where the expertise of a dedicated leak detection company proves invaluable.
What Methods Are Used for Leak Detection?
Leak detection companies like Harmuns use a variety of modern technologies to pinpoint leaks quickly and accurately. Here’s a breakdown of the most common methods. For more information about these methods or the equipment used for these then click here.
1. Acoustic Leak Detection
This method uses sensitive listening equipment to detect the sound of water escaping from pressurised pipes. Since even a small leak creates a high-frequency noise, acoustic sensors can isolate the exact location – especially in central heating systems, mains water supplies, and underground pipework.
2. Tracer Gas Detection
In cases where acoustic methods fall short (such as in plastic pipes or low-pressure systems), a safe gas mixture is introduced into the pipework. This gas escapes through the leak and rises to the surface, where it can be detected using sensitive probes.
Tracer gas is especially useful for finding leaks under solid floors, in walls, or beneath driveways.
3. Thermal Imaging
Thermal cameras detect differences in temperature across a surface. When water leaks from a pipe, it often causes a thermal irregularity. By scanning walls, floors, or ceilings, technicians can identify where cooler or warmer zones suggest a leak.
This is particularly effective for underfloor heating systems or leaks in hot water lines.
4. Moisture Mapping
Moisture meters are used to track the spread of water in materials such as plaster, wood, or concrete. By mapping out how moisture travels, technicians can narrow down the source – even if the water has migrated from its original point of entry.
Additionally, advanced leak detection companies like Harmuns will also use pipe locators, endoscope cameras, drones, steam generators, salts analysis and other types of specialist equipment.

What Happens if I Leave a Leak Undetected?
Failing to identify a hidden leak can lead to serious and costly consequences over time, including:
- Structural damage to floors, walls, and foundations
- Rotting timber and weakened supports
- Black mould, mildew, and poor indoor air quality
- Escalating water bills
- Insurance complications and rejected claims
Overwhelmingly, the cost of professional leak detection is far less than the long-term damage caused by ignoring the issue or relying on trial-and-error solutions that involve tearing up floors or opening walls. It is much better of fixing a leak early than letting it build up and get worse over time, becoming increasingly expensive as time goes on. According to ‘I Love Claims’, leaking pipes and taps have cost UK homeowners £13.6 billion to repair across 2019. Read more about this statistic here.
Why Not Just Use a Plumber?
Traditional plumbers are excellent for visible leaks or routine plumbing repairs. However, when the leak is invisible, even the most experienced plumber may not have the specialised tools required to find the source accurately.
That’s where leak detection companies come in. We support plumbers by doing the investigative work, pinpointing the leak so that the repair can be made precisely and efficiently. Our engineers can also access and fix the pipe leak for you too.
When Should I Call a Leak Detection Company?
Here are some common signs that it’s time to call Harmuns:
- Sudden spike in your water bill with no clear reason
- Persistent damp or mould in one area
- Low water pressure without a known cause
- Sound of running water when all taps are off
- Hot or cold spots on your floor or walls
- Water stains or bubbling paint
- Underfloor heating not working properly
Even if you’re unsure, it’s worth speaking to a professional. A brief phone call could prevent weeks of disruption and thousands of pounds in repairs.
