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
Characterised by newer residential towers built over historic infrastructure, and smaller Victorian warehouses converted to live-work units. This creates a 'building atop building' scenario with disparate plumbing systems. New towers often use plastic plumbing within stud walls, while conversions retain old lead and iron runs. Ground conditions are often made-up, affecting drainage.
Engineer's note
In Aldgate's hybrid old/new buildings, we combine thermal imaging to identify wet partitions from plastic pipe leaks with moisture mapping to define the exact extent of infiltration from below-ground sources.
Covered in Aldgate
- 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 Aldgate
01
Differential Settlement Stress
New towers settling on old foundations stress plumbing connections between old and new sections. This leads to failures at transition points, with leaks entering the gap between original and new structures, appearing unpredictably.
02
Warehouse Conversion Drainage
Original warehouse ground floors were designed for wet processes. New residential drainage added above often ties inadequately into old clay or brick subterranean drains, leading to blockages and leaks at these hidden, inaccessible junctions.
03
Plastic Pipework Movement
Plastic plumbing in newer tower stud walls expands/contracts significantly. Over time, this movement abrades pipes at clip points or causes joint fatigue, leading to leaks inside partitions that drip into lower floor cavities before detection.
04
Made-Ground Drainage Surcharge
Historic made-ground affects drainage fall. During heavy rain, surcharged drains can back up, forcing water up through old disconnections or cracks in below-ground pipework, manifesting as ground-floor flooding from below, not from internal pipes.
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 — Characterised by newer residential towers built over historic infrastructure, and smaller Victorian warehouses converted to live-work units. This creates a 'building atop building' scenario with disparate plumbing systems. New towers often use plastic plumbing within stud walls, while conversions retain old lead and iron runs. Ground conditions are often made-up, affecting drainage.
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.
