This page is here to help homeowners in Steyning who may be experiencing an underground leak, including wet ground, water pooling, saturated lawns, driveway leaks, and other signs of buried pipework problems. The Leak Hunter specialises in locating and repairing underground leaks, using non-invasive techniques to trace the source accurately before recommending the most appropriate solution.
The Leak Hunter is a specialist leak detection company, so if your symptoms relate to a different type of leak, we can still help. You can explore our other leak detection services using the menu above, or contact us and we’ll point you in the right direction.
Water surfacing, saturated ground or recurring wet patches around a property in Steyning (BN44) can sometimes indicate an underground pipe leak beneath buried pipework. Because these leaks develop below the surface, water often travels through surrounding soil before the source becomes visible elsewhere around the property.
Steyning includes a mix of period homes, detached properties, family housing and residential developments, many with buried pipework running beneath gardens, pathways, patios and driveways. Our underground leak detection Steyning service uses acoustic listening equipment and tracer gas testing to locate underground leaks within buried pipework and confirm the exact leak position before excavation begins.
When underground pipework starts leaking beneath outside ground, the signs may develop gradually over time. Soft ground, damp soil, water pooling or unusually wet areas around gardens, pathways, patios and driveways can all indicate water escaping below the surface and may require specialist investigation to identify the precise leak location.
We carry out underground leak detection and investigation services throughout Steyning and nearby areas including Bramber, Upper Beeding and Shoreham-by-Sea, while our wider service operates across the county through our Underground Leak Detection West Sussex service.

Underground Leak Detection – What It Means
Underground leak detection is the process of locating water escaping from pipework buried beneath external ground such as gardens, driveways, patios, or paths in Steyning.
Because the pipework is hidden below soil or hard surfaces, the leak location is rarely visible at the surface. Specialist testing equipment allows engineers to pinpoint the exact escape point before any excavation begins.
By confirming the precise leak location first, repairs can be planned properly and disruption can usually be kept to a minimum.
Why Underground Leaks Can Cause Serious Problems
Underground leaks do not always appear directly above the damaged pipe. Water can travel through soil and sub-base materials before becoming visible, which means the wet area may be some distance away from the actual escape point.
If left unresolved, an underground leak in Steyning may contribute to:
Persistent wet ground or water pooling outdoors
Soft or unstable ground in gardens or driveways
Damage to patios, paths, or paved surfaces
Ongoing water loss and unnecessarily high bills
Damp or moisture affecting nearby structures
Professional underground leak detection helps confirm the location early, reducing guesswork and avoiding unnecessary digging.
Why Underground Pipework Develops Leaks
Buried external pipework is exposed to environmental pressure over time. Even when the leak is not visible at the surface, the pipe below ground may already have weakened or failed.
Common causes include:
Ageing pipe materials such as older metal or plastic pipework
Ground movement caused by weather changes or shifting soil
Tree root intrusion affecting buried external pipe runs
Weak joints, fittings, or earlier repair points failing over time
Pressure stress within the water supply pipework
Damage caused by previous building or landscaping work
Understanding the likely cause helps determine the most effective detection method and the right repair approach once the leak has been identified.
How to Spot an Underground Leak
Signs of an underground leak often develop gradually because water moves through the ground before reaching the surface. Many homeowners in Steyning first notice the symptoms before they know where the leak is coming from.
Common indicators include:
Persistent wet patches in lawns, borders, or garden areas
Water pooling near driveways, patios, or paths
Grass or planting growing greener and faster in one area
Soft, sinking, or unstable ground outdoors
Cracks or movement in external hard surfaces
An unexplained increase in water usage or bills
If you notice these symptoms, a professional investigation can confirm whether a buried pipe leak is present and narrow down the affected area accurately.

All our work is carried out under comprehensive insurance cover and in accordance with recognised national safety and water system standards.
As Gas Safe registered engineers and a WaterSafe approved company, we work to recognised national safety and water system standards when assessing, locating, isolating, and repairing domestic pipework.
Where required, structured trace and access documentation can be provided for insurers, clearly detailing the confirmed fault location, the diagnostic process undertaken and post-repair pressure verification.
Every investigation concludes with confirmed system integrity — not assumption.
Where Underground Leaks Commonly Occur
Underground leaks in Steyning can develop wherever pipework runs beneath external ground around the property. This often includes buried pipes beneath gardens, driveways, patios, paths, and landscaped areas where water supply pipes or other external pipe runs pass below the surface.
Common locations include:
Beneath gardens and planted areas
Below driveways and paved parking areas
Under patios, terraces, and garden paths
Along external pipe runs entering the property
Beneath lawns where longer buried pipe sections are present
Because water can travel through the ground, the visible wet area may not sit directly above the leak itself. That is why specialist leak detection equipment is used before any excavation begins.
Our Underground Leak Detection Methods
We use non-destructive testing methods to locate underground leaks accurately while keeping disruption to a minimum.
Acoustic Listening
Sensitive acoustic equipment is used to detect the sound of escaping water travelling through buried pipework.
Ground Microphones
Ground microphones help narrow down leaks beneath external hard surfaces such as driveways, patios, and paths.
Tracer Gas Testing
A safe inert gas can be introduced into the affected pipework. Detection equipment then identifies where the gas escapes through the ground surface.
Thermal Imaging
Temperature differences can sometimes help reveal moisture movement or temperature changes caused by a buried leak.
Pressure Testing
Pressure testing helps confirm whether a section of pipework is losing pressure and supports the wider diagnosis.
By combining the most suitable methods for the site, we can usually locate underground leaks accurately without unnecessary excavation.
Not sure what’s causing the issue? Our engineers can review the symptoms and advise on the best next step.
Once the leak has been located, the right repair approach can be confirmed based on the pipe type, access conditions, and exact fault location.
Repair options may include:
Targeted excavation where the escape point has been accurately identified
Localised pipe repair where the damaged section is accessible
Section replacement if the affected pipework has failed beyond repair
Alternative repair planning where a different route or access method is more suitable
Because the leak is diagnosed first, repairs can be planned more efficiently and unnecessary disruption can often be avoided.
FAQs – Underground Leak Detection Steyning
How do I know if I have an underground leak?
Common signs include wet patches in gardens, water pooling near paved areas, unusually green grass, soft ground, or a rise in water usage. A professional investigation can confirm whether a buried pipe is leaking.
Can you detect underground leaks without digging?
Yes. In many cases we can locate underground leaks using non-invasive methods such as acoustic testing, tracer gas, ground microphones, and pressure testing before any excavation is needed.
How accurate is underground leak detection?
Our testing methods are designed to narrow the leak to a small targeted area, helping keep excavation and disruption to a minimum.
How long does underground leak detection take?
Most domestic underground leak investigations are completed within a single visit, depending on access, pipe layout, and site conditions.
Can you provide an insurance report?
