Leak Detection Bank
Hidden water leaks in Bank pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Bank buildings.
Local knowledge
Bank housing, from a leak engineer's side
This area is primarily historic commercial buildings now containing luxury residential conversions. Plumbing systems are often a hybrid of original commercial pipework and new residential installations, routed through deep floor voids and service shafts. Leaks in these concealed vertical risers can affect multiple high-value units, with water following the path of least resistance through old chase lines and cable ducts, complicating source identification.
Engineer's note
We document the exact pathway of water ingress from the source to the damage, which is crucial for insurers managing claims where multiple high-net-worth policies in a single building may be involved.
Covered in Bank
- 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
What fails here
Common leak problems in Bank
01
Riser Leak in Multi-Unit Building
A leak in a shared pressurised water riser serving upper-floor apartments can discharge significant volumes. Water flows down the riser chase, entering flats on lower levels through penetration points, requiring systematic isolation testing to identify the faulty section for the insurer.
02
Void Leak from Neighbouring Property
Water from a leak in one converted office suite can travel extensively through interconnected ceiling and floor voids before dripping into an adjacent property. We trace the moisture path back to its origin, providing the evidence needed to establish liability between two different insurance policies.
03
Failed Lead Main Saddle
Some conversions retain sections of original lead incoming mains. A failed saddle or joint on this main, often located in a communal cellar or void, can supply a constant, hidden leak that soaks foundations and lower-floor apartments.
04
AC Condensate Drain Blockage
Dedicated air-conditioning systems in high-end conversions have condensate drains that can block and overflow. Water then runs along cable trays and ducting, appearing as a leak unrelated to the plumbing system, which we differentiate to prevent a wrongful claim denial.
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 Bank — FAQs
How quickly can you attend a leak in Bank?
Same-day appointments are usually available in Bank 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 Bank?
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.

Plumbing systems are often a hybrid of original commercial pipework and new residential installations, routed through deep floor voids and service shafts. Leaks in these concealed vertical risers can affect multiple high-value units, with water following the path of least resistance through old chase lines and cable ducts, complicating source identification.
Can you provide a report for my insurer?
Every Bank detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
