Local knowledge
How Wandsworth properties leak
Wandsworth housing is dominated by Victorian terraces, mansion blocks and new riverside towers. Side-return kitchen extensions across Wandsworth bury pipe joints at the old external wall line — the single most common leak point we find here.
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 Wandsworth
- Hidden leaks under floors and in walls
- Underground supply pipe leaks

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 Wandsworth
Side-Return Kitchen Extension Leaks
The most frequent leak source in Wandsworth is the buried pipe joint at the original external wall line, created by side-return kitchen extensions. This joint becomes inaccessible and is prone to failure due to ground movement and corrosion. Our trace and access process precisely locates this point, providing the evidence insurers require to approve repair and reinstatement claims.
Victorian Terrace Lead Pipe Degradation
Original lead supply pipes in Victorian terraces are at high risk of pinhole leaks and fractures, especially at connections. We systematically trace the pipe run to identify failure points. Documenting the condition and location is critical for insurer approval, as it validates the need for full replacement, which is often a recoverable cost under policy terms.
Mansion Block Concealed Leaks
In Wandsworth's mansion blocks, leaks within floor voids and behind original tiling can travel far from the source, causing damage in multiple units. Our non-invasive detection methods pinpoint the exact origin. This precise evidence is essential for insurers to correctly apportion liability and costs between leaseholders and freeholders, preventing claim disputes.
New Tower Pressure & Joint Issues
High-pressure systems in new riverside towers can cause failures at push-fit joints and appliance connections. We test system pressure and use thermal imaging to find leaks. Providing a full system report demonstrates the systemic nature of the issue to insurers, supporting claims for remediation beyond a simple spot repair.

Leak detection in Wandsworth — FAQs
How quickly can you attend a leak in Wandsworth?
Same-day appointments are usually available in Wandsworth, 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 Wandsworth 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 Wandsworth detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Wandsworth do you cover?
All of it — including Battersea, Putney, Balham, Tooting, Earlsfield. We cover every London borough, so coverage never depends on which side of a postcode line you live.
Why does my Wandsworth side-return extension leak where the old wall used to be?
That junction, where the new extension roof meets the original external brick wall, is the weakest weathering line in most Balham and Tooting terraces. Flashing, upstands and the roof-to-wall seal all meet there, so any gap lets water track inside along the old wall. We use thermal and acoustic checks at that junction to locate the entry point before anyone opens up finishes.
Water is coming through into my flat from the riverside tower above. Who pays?
In Nine Elms and Battersea blocks, that usually depends on your lease and where the fault sits. A leak from another flat's push-fit pipework is normally that leaseholder's responsibility, while common pipes fall to the freeholder or managing agent. Our job is to trace the source and document it clearly, so the right party and their insurer can be approached. A typical trace and report sits in the fixed fee range of £250 to £450.
