Leak Detection Pimlico
Hidden water leaks in Pimlico pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Pimlico buildings.
Local knowledge
Pimlico housing, from a leak engineer's side
Pimlico is dominated by Victorian mansion blocks and terraces built on a grid pattern, with many properties featuring original plumbing layouts. The dense housing and network of basement areas create challenges for leak detection in shared waste runs. Numerous properties are held under long leases, placing responsibility for internal pipework on leaseholders, while freeholders control the mains. This split requires precise leak origin documentation.
Engineer's note

What fails here
Common leak problems in Pimlico
01
Shared Waste Stack Leaks
Leaks from cast-iron waste stacks serving multiple flats in Pimlico mansion blocks are common. We use drain cameras and moisture mapping to trace the exact point of failure. Our report specifies whether the leak originates from a communal stack or a branch serving one flat, which dictates whose insurer is liable.
02
Basement Damp from Concealed Mains
The original water mains often run through basement voids, and leaks here are mistaken for rising damp. We isolate and trace these concealed feeds to provide definitive proof of a plumbing fault. This evidence stops unnecessary damp-proofing claims and redirects insurers to the correct water damage cover.
03
Balcony Drainage Intrusions
Leaks from blocked balcony drains on upper floors can penetrate into ceilings below. We test drainage routes and document the blockage location and resultant damage path. This establishes the sequence of events required for insurers to process a resulting water damage claim.
04
Leak Escalation in Communal Hallways
A leak from one flat often first appears in a shared hallway, complicating liability. We work with the managing agent to test individual supplies and map the leak's source. Our findings provide the evidence chain insurers need to correctly assign the claim to the responsible leaseholder's policy.
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.
