Local knowledge
How Southwark properties leak
Southwark housing is dominated by Victorian terraces, warehouse conversions and large estates. Warehouse conversions near the river mix cast-iron stacks with modern plastic; failed transitions between the two are a signature Southwark leak.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Southwark
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
Common leak problems in Southwark
Cast-Iron to Plastic Stack Transitions
Warehouse conversions along the river feature original cast-iron soil stacks connected to modern plastic systems. The joint between these different materials is a frequent failure point, leading to hidden leaks within walls and voids that can quickly escalate.
High-Pressure Failures in Victorian Terraces
Original pipework in Victorian homes was not designed for modern mains water pressure. This constant stress leads to pinhole leaks in aging supply lines, often concealed under floorboards or behind original plaster, requiring urgent detection to prevent structural damage.
Concealed Leaks in Large Estates
The complex, shared plumbing networks in large housing estates mean leaks can travel far from their source. Water can seep between flats or through concrete slabs, making the origin difficult to pinpoint without specialised electronic leak detection equipment.
Failed Lead Service Pipe Connections
Many properties still have sections of original lead supply piping. Corrosion and movement at the connection points to newer copper or plastic pipes create a common source of underground leaks, often noticed as a drop in water pressure or damp patches in foundations.

How to Choose a Leak Detection Company in London: Speed is Everything
Choosing a leak detection company in London comes down to one critical factor: response speed. Here’s how to ensure you get immediate, 24/7 action.
Leak detection in Southwark — FAQs
How quickly can you attend a leak in Southwark?
Same-day appointments are usually available in Southwark, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Southwark is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Southwark detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Southwark do you cover?
All of it — including Peckham, Dulwich, Bermondsey, Camberwell, Rotherhithe. We cover every London borough, so coverage never depends on which side of a postcode line you live.
Why do leaks in Southwark warehouse conversions often appear in a neighbour's flat?
In converted Bermondsey and Rotherhithe warehouses, pipework is frequently boxed into shared floor and ceiling voids, so water from one flat can travel along beams and emerge in the flat below or beside it. Non-invasive moisture mapping and tracing help identify the true source before finishes are opened, which also clarifies which leaseholder's demise the fault sits within for insurance purposes.
Do you find the cast-iron-to-plastic transition leaks common in older Southwark homes?
Yes. Many Victorian terraces around Camberwell, Peckham and Dulwich have had sections of original cast-iron or lead pipe joined to modern plastic over the years, and these transition joints are a frequent slow-leak point. We trace the run and confirm the source, then provide an insurer-ready report. A typical fixed investigation fee runs in the region of £250 to £450 as a UK trade cost-guide range.
