Leak Detection Aldgate
Hidden water leaks in Aldgate pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Aldgate buildings.
Local knowledge
Aldgate housing, from a leak engineer's side
Aldgate, on the City's eastern edge, has seen extensive redevelopment: new residential and serviced-apartment towers, office-to-residential conversions and mixed-use blocks sitting above shops, restaurants and workspace. Newer towers stack many flats over shared plant and communal risers, while conversions retain a mix of commercial and retrofit domestic pipework behind modern finishes. Leaks hide here for familiar City reasons: concealed vertical risers carry water down through several floors, communal systems blur responsibility, and slab and screed construction lets water travel sideways so the stain surfaces far from the pipe that actually failed above.
Engineer's note
In Aldgate we match the method to the building: correlation and thermal imaging along communal risers in the towers, and moisture mapping the slab soffit in framed blocks to find the true origin when the drip appears far from the fault. On buried runs we add tracer gas to pin a short section. We coordinate access with managing agents, building management and porters, and issue an insurer-ready trace and access report.
Covered in Aldgate

What fails here
Common leak problems in Aldgate
01
Communal riser leaks in new towers
Aldgate's residential and serviced-apartment towers rely on shared risers for heating and water across many stacked dwellings. A weeping joint or pinhole in the shaft feeds down and appears floors below with no obvious owner, while pressure on the system slips. We isolate legs, pressure-test the loop and use acoustic correlation along the riser to fix the leaking level, giving the managing agent a clear answer without disturbing every flat on the stack.
02
Mixed-use leaks reaching retail and dining below
Flats and serviced apartments sit above shops and restaurants, so an upstairs leak often surfaces first in a commercial ceiling, through downlights or over a kitchen. The occupier assumes the source is directly overhead, but water usually tracks across the slab first. We survey from below and above, arrange access to the units, and confirm the true origin so the repair is precise and the business faces minimal closure.
03
Slab water travelling from the true source
In Aldgate's newer concrete-framed blocks, water from a failed pipe runs along the slab soffit until it finds a penetration or joint to drop through, so the visible drip sits away from the fault. Following the stain damages ceilings for nothing. We moisture map the soffit, read the wet gradient and trace the water back to its genuine entry point before recommending where, and whether, to open up.
04
Retrofit pipework failing behind new finishes
Converted floors and new fit-outs bury domestic pipework in screed and behind dry lining, mixing retained commercial runs with newer plastic and copper. Stressed joints and redundant branches then fail out of sight. Tracer gas into the isolated system escapes at the fault and is detected at the surface, and thermal imaging confirms the route, so we open the finish at the failed fitting rather than along the whole run.
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 Aldgate — FAQs
How quickly can you attend a leak in Aldgate?
Same-day appointments are usually available in Aldgate 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 Aldgate?
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 Aldgate properties?
Yes — Aldgate, on the City's eastern edge, has seen extensive redevelopment: new residential and serviced-apartment towers, office-to-residential conversions and mixed-use blocks sitting above shops, restaurants and workspace. Newer towers stack many flats over shared plant and communal risers, while conversions retain a mix of commercial and retrofit domestic pipework behind modern finishes. Leaks hide here for familiar City reasons: concealed vertical risers carry water down through several floors, communal systems blur responsibility, and slab and screed construction lets water travel sideways so the stain surfaces far from the pipe that actually failed above.
Can you provide a report for my insurer?
Every Aldgate detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
