Local knowledge
How Lambeth properties leak
Lambeth housing is dominated by Victorian terraces, converted flats and large estates. Split Victorian houses share old supply pipes; when one conversion leaks, the bill and the damage often land on a different flat entirely.
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 Lambeth
- 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 Lambeth
Shared Victorian Supply Pipe Leaks
In converted Victorian terraces, the original single lead or iron supply pipe often still serves multiple flats. A leak in this shared section can cause damage in one flat while originating from the common infrastructure. Insurers require clear evidence tracing the leak source to the shared pipe to determine liability and approve claims. Our investigation documents the pipe routing and the precise failure point for your insurer.
Leak Migration Between Converted Flats
Water from a leak in an upstairs flat in a Victorian conversion can travel down cavity walls or service ducts, appearing as damage in a lower flat. This creates disputes over responsibility. We provide detailed moisture mapping and access reports to prove the leak's origin path, which is essential documentation for insurers to process the claim correctly and assign costs.
Estate Plumbing System Failures
Large estates in Lambeth have extensive, aging communal plumbing systems. A failure in a central riser or lateral pipe can affect numerous properties simultaneously. Our trace and access service identifies the exact failure point within the complex system, providing the evidence insurers need to approve major repair works and manage large-scale claims efficiently.
Concealed Leaks in Party Walls
In terraced housing, plumbing often runs within shared party walls. A leak here can damage adjoining properties, complicating insurance claims. We use non-invasive detection to locate the leak without unnecessary damage, then provide minimally invasive access evidence. This controlled approach satisfies insurer requirements for justified repair costs and clear liability assessment.

How to Choose a Leak Detection Company in London
Choosing between companies you cannot assess technically is the hard part of a hidden leak. Six questions separate a survey from a guess, and the answers tell you more about the outcome than any review ever will.
Leak detection in Lambeth, FAQs
How quickly can you attend a leak in Lambeth?
Same-day appointments are usually available in Lambeth, 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, where the leak is inside your own property. Attend a confirmed live leak in Lambeth, fail to locate it, and the detection fee is waived. The promise stops at your boundary: if the survey shows the water is arriving from an adjoining property, a communal pipe or the supplier's main, that leak has been found and the visit is charged.
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 Lambeth detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Lambeth do you cover?
All of it, including Brixton, Clapham, Streatham, Stockwell, West Norwood. We cover every London borough, so coverage never depends on which side of a postcode line you live.
Our building has three flats and a share of freehold. Who notifies the insurer?
The company that holds the freehold is the policyholder, so notification should come from it, normally through whichever director handles the administration. In practice the person whose flat is damaged often reports it first, and that is fine provided the company then confirms. The awkwardness is that the same small group has to decide the repair, hold the money and apportion the excess, while one of them is the loser. Writing down beforehand how the company handles claims, excesses and access is one of the more useful things a small freehold company can do.
The leak came from the flat above, owned by another shareholder. How is that handled?
In a share of freehold building the buildings policy generally responds to the damage regardless of which flat the water came from, because the insured is the company and the building is the subject matter. Fault is a separate question and is often absent altogether when a pipe simply fails. Where a neighbour has been careless, the insurer may consider recovery, but that is its decision. What keeps the relationship intact is an independent record of the origin, so the conversation is about a pipe rather than about a person.
How is the excess shared between flats in a small freehold company?
That depends on the leases and on whatever the company has agreed, not on insurance law. Many leases apportion building costs by a stated percentage, and an excess is arguably such a cost; others are silent, which leaves it to negotiation. The unattractive alternative, where nothing is written down, is that the excess falls on whoever shouts least. Settling the principle in advance avoids a dispute at the worst moment. A documented origin at least removes the temptation to allocate the excess by blame rather than by lease.
I am a council leaseholder in Lambeth. What comes through insurance and what does not?
An insured event such as an escape of water damaging the structure normally goes through the buildings policy the freeholder arranges. Renewal or repair of ageing communal installations is not an insured loss; it is major works, which carry a statutory consultation process and reach you as a service charge demand. The two routes cost you very different amounts, so where a failure becomes the trigger for a wider programme it is worth understanding which you are being asked to fund. Internal items typically depend on what the lease demises to you.
What should a small freehold company keep on file about the building?
Enough that a claim does not start from nothing. The current policy schedule with the escape of water excess clearly noted, the leases, a plan showing the demise boundaries, contact details for every flat including any tenant, and a record of previous losses and repairs. Add to that any survey or report identifying where services run, because in a converted terrace nobody knows otherwise. Buildings that hold this material settle claims noticeably faster, simply because the first fortnight is not spent assembling it.
