Leak Detection Moorgate
Hidden water leaks in Moorgate pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Moorgate buildings.
Local knowledge
Moorgate housing, from a leak engineer's side
Moorgate blends established office stock with a wave of new residential and serviced-apartment towers and office-to-residential conversions around the northern edge of the City. Newer tall blocks stack many dwellings over communal plant and deep basements, while older converted buildings carry a mix of retained commercial and retrofit domestic pipework. Services run through concealed risers and boxed routes behind modern dry linings and screeds. Leaks hide because tall-block risers carry water down many floors before it shows, and slab and screed construction lets a small failure spread sideways and surface a long way from the pipe that actually gave way.
Engineer's note
In Moorgate's tall blocks we treat the riser as the prime suspect, correlating and thermally imaging along the shaft to find the leaking floor before any access is cut. On buried screed and conversion pipework we combine moisture mapping with tracer gas to fix a short failed section. We coordinate with building management, managing agents and concierge, and provide an insurer-ready trace and access report for the freeholder.
Covered in Moorgate

What fails here
Common leak problems in Moorgate
01
Riser leaks feeding down many floors
Moorgate's newer towers run heating, cold water and drainage through vertical risers serving stacked flats and serviced apartments. A failed joint high in the shaft sends water down inside the riser, emerging several floors below on a landing or in a lower unit. We use acoustic correlation and thermal imaging on the riser to identify the leaking floor, so access opens on one level rather than stripping fire-rated shafts across the whole stack.
02
Basement and lower-ground water ingress
Deep basements under new and converted blocks house plant, parking and stores, and are a common place for leaks and ingress to collect. Distinguishing a failed pressurised pipe from groundwater or a tanking defect matters for both the repair and the claim. We test and isolate the mechanical services, survey moisture patterns across the structure and separate a plumbing failure from external ingress before any digging or breaking out begins.
03
Screed leaks spreading under new floors
Conversions and new fit-outs bury underfloor heating and water pipes in screed. A pinhole releases water that spreads through the screed and surfaces at a doorway, skirting or the floor below, well away from the break. Thermal imaging reads the warm or cool plume through the finish and moisture mapping defines its extent, letting us mark a short section of floor to lift rather than the entire room.
04
Concealed conversion pipework behind dry lining
Office-to-residential floors box retained and retrofit pipework behind modern plasterboard and metal-stud linings. Failed fittings and stressed joints sit hidden until damp appears. Tracer gas into the isolated pipework escapes precisely at the fault and registers at the surface, and thermal survey confirms the run, so we can open the wall at the failed fitting instead of chasing the whole route.
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.
Leak detection in Moorgate — FAQs
How quickly can you attend a leak in Moorgate?
Same-day appointments are usually available in Moorgate and across City of London, and next-day almost always. If water is actively escaping, say so when you book — live leaks are prioritised and we can talk you through isolating the supply while the engineer travels.
What does leak detection cost in Moorgate?
A fixed fee agreed at booking — typically £250–£450 for a domestic detection visit — covered by no find, no fee. That includes pressure testing per circuit, thermal imaging, acoustic survey and moisture mapping. Repairs are quoted separately before any work starts.
Do you know Moorgate properties?
Yes — Moorgate blends established office stock with a wave of new residential and serviced-apartment towers and office-to-residential conversions around the northern edge of the City. Newer tall blocks stack many dwellings over communal plant and deep basements, while older converted buildings carry a mix of retained commercial and retrofit domestic pipework. Services run through concealed risers and boxed routes behind modern dry linings and screeds. Leaks hide because tall-block risers carry water down many floors before it shows, and slab and screed construction lets a small failure spread sideways and surface a long way from the pipe that actually gave way.
Can you provide a report for my insurer?
Every Moorgate detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
