We use specialist equipment to locate leaks and recommend a suitable repair. Acting promptly can limit disruption and reduce the risk of damp, mould and further damage.

Signs You May Have a Water Leak
Water leaks are not always obvious. If you notice any of the following signs, it may be worth arranging a professional leak detection survey:
- An unexplained increase in your water bill
- Damp patches on walls, floors or ceilings
- The sound of running water when no taps or appliances are in use
- A drop in water pressure
- Mould or mildew appearing in unusual areas
- Warm patches on a floor, which could indicate a leak in underfloor heating or hot water pipework
- Pooling water outside the property or in the garden
- New cracks or movement alongside other signs of a possible underground leak
If you notice any of these signs, contact us for an assessment. Finding the cause early may help limit damage and the cost of repairs.
Detecting a Water Leak
Leaks hidden underground or within walls can be difficult to locate without specialist equipment. Professional leak detection helps narrow down the source before repair work begins.
At Elliott Environmental Drainage we combine experience with specialist equipment to investigate leaks in domestic and commercial pipework. Our engineers assess the problem, locate the source and advise on the repair, aiming to keep disruption to a minimum.
Our Leak Detection Methods and Technology
We use a range of methods to investigate hidden leaks and avoid unnecessary excavation where possible:
- Acoustic listening devices help identify the sound of water escaping from pipework
- Thermal imaging cameras can reveal temperature differences associated with some hidden leaks
- Tracer gas detection helps locate leaks by tracking gas introduced into suitable pipework
- Moisture meters and mapping help assess where water has spread and narrow down a possible source
- CCTV pipe inspection uses a camera to examine the inside of accessible pipework
Depending on the site and the pipework involved, these methods can help us investigate leaks in water mains, supply pipes, underfloor heating and internal plumbing. For related inspections, see our CCTV drain survey services.
Burst Pipe Repairs
A burst pipe needs prompt attention. Whether the problem affects a water main, supply pipe or internal plumbing, our team is available 24/7 to provide fast, professional burst pipe repair services across London, Kent and the South East.
What to do if you have a burst pipe:
- Turn off the water supply at the stopcock if it is safe and accessible
- Switch off the heating system and water heaters if it is safe to do so
- Open taps to drain water remaining in the pipework, where appropriate
- Move valuables away from the affected area if you can do so safely
- Call our emergency team and explain where the pipe has burst
Where suitable, we can consider no-dig methods to repair or replace damaged pipework. The approach depends on the location and condition of the pipe and the extent of the damage.
What Causes a Burst Water Main?
If you suspect a leaking or burst water main, act quickly to limit water loss and damage. Elliott Environmental Drainage Ltd provides commercial and domestic water leak detection services across London, Kent and the South East. We can assess the problem and recommend the next steps.
Water mains can burst for several reasons. Corrosion can weaken older pipework, while freezing and thawing can put stress on pipes. Changes in pressure and nearby excavation work may also damage a main.
A burst water main can interrupt your water supply and damage nearby property. Signs may include unexplained damp, pooling water or a sudden drop in pressure. If you notice them, arrange an assessment promptly.
We also provide related services, including pump station servicing. Contact us to discuss a suspected water main leak and the help you need.
Types of Water Leaks We Detect and Repair
We investigate and repair a range of water leaks, including:
Water main leaks — leaks in larger mains pipework, which is often underground and can lead to substantial water loss.
Supply pipe leaks — leaks in the pipe that carries water from the main towards a property. Responsibility for repairs depends on where the leak is and who owns the pipe.
Underground leaks — leaks in buried pipework that may show up as damp, pooling water or an unexplained rise in water use.
Internal pipe leaks — leaks within your property’s plumbing system, including behind walls, under floors or in ceiling voids.
Commercial water system leaks — leaks in pipework serving offices, factories, hospitals and schools. Our commercial water leak detection services are designed for minimal business disruption.
