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
Bank is dominated by historic commercial buildings now containing luxury residential conversions above ground-floor banking halls. Plumbing is often a retrofit, with new pipework weaving around historic structures and through floor voids. High ceilings and multi-tenant buildings mean long vertical pipe runs are common. Leaks here can quickly affect sensitive electronic infrastructure in commercial spaces below. Pressure fluctuations from the dense network of offices switching systems on and off contribute to pipe stress.
Engineer's note
In Bank, a leak threatens both home and business. We prioritise rapid containment to limit commercial disruption, with engineers on call round the clock.
Covered in Bank

What fails here
Common leak problems in Bank
01
Void leak cascades
A leak in a floor void above a banking hall can cascade down through light fittings and cable runs, risking significant commercial damage. If you hear water in a ceiling void, do not wait. Call us for an immediate trace-and-access mission to protect the property below.
02
Retrofit pipe joint failure
Pipework added during conversion can have joints that fail under the vibration from constant street-level traffic. These leaks often start small but worsen rapidly. Our engineers carry parts for common retrofit systems to effect a fast repair at any hour.
03
Basement pump system faults
Many buildings here have basements below the water table, relying on sump pumps. A pump failure or pipe burst in these areas leads to rapid flooding. If your basement alarm sounds or you see water rising, evacuate the area and call us for emergency pump deployment and leak sealing.
04
Lead replacement pipe leaks
Older lateral connections from the main may still be in lead, which can fail at the transition to modern copper inside the building. This causes unexplained water loss and pressure issues. We can pressure-test and trace these lines to locate the breach without extensive excavation.
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.
Do you know Bank properties?
Yes — Bank is dominated by historic commercial buildings now containing luxury residential conversions above ground-floor banking halls. Plumbing is often a retrofit, with new pipework weaving around historic structures and through floor voids. High ceilings and multi-tenant buildings mean long vertical pipe runs are common. Leaks here can quickly affect sensitive electronic infrastructure in commercial spaces below. Pressure fluctuations from the dense network of offices switching systems on and off contribute to pipe stress.
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.
