Local knowledge
How Westminster properties leak
Westminster housing is dominated by stucco terraces, mansion blocks and serviced apartments. Mansion blocks with concealed risers need landlord and porter coordination; we isolate, trace and document for freeholders and managing agents.
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.

Three methods, one marked point
Acoustic survey

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 Westminster
Concealed Riser Leaks
In Westminster's mansion blocks, plumbing risers are often concealed within walls or service ducts. A leak here can travel unseen between floors, damaging multiple properties. We isolate the affected riser and use trace-and-access techniques to pinpoint the leak, coordinating with porters to minimise disruption.
Stucco Terrace Pipework Corrosion
The stucco-fronted terraces often have original or ageing iron and lead pipework. Corrosion and pinhole leaks are common, especially where pipes run behind decorative plasterwork. We use electronic leak detection to find the source without unnecessary damage to period features.
Serviced Apartment Pressure Fluctuations
High-turnover serviced apartments experience constant demand on water systems, leading to pressure surges. This stresses joints and valves, causing sudden failures. We respond to isolate the issue and repair the specific fitting, often working with the building's management team out-of-hours.
Landlord & Freeholder Coordination
Leaks in multi-occupancy buildings require immediate liaison with managing agents, freeholders, and porters. We handle this coordination from the first call, providing clear documentation on the leak's source and required repairs to streamline the process for all parties.

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 Westminster — FAQs
How quickly can you attend a leak in Westminster?
Same-day appointments are usually available in Westminster, 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 Westminster 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 Westminster detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Westminster do you cover?
All of it — including Marylebone, Pimlico, Paddington, Mayfair, St John’s Wood. We cover every London borough, so coverage never depends on which side of a postcode line you live.
Who arranges access when the leak is in a Westminster mansion block?
Usually the managing agent or porter coordinates access to the affected flats, since a communal riser or the flat above is often involved. We work to that arrangement rather than around it, booking a slot that suits residents and building staff, and we keep the freeholder or agent informed so access to each flat is agreed before we start tracing the source.
Can you find the leak without opening up period plaster or communal risers?
We aim to correlate the likely source before anything is opened up, using non-destructive tracing across the affected flats and riser route. This narrows the work to the probable source rather than exploratory removal of ornate plaster or hardwood. A fixed fee of £250 to £450 applies, in line with typical UK trade cost-guide ranges, with an insurer-ready report for the freeholder or managing agent.
