Leak Detection Bow
Hidden water leaks in Bow pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Bow buildings.
Local knowledge
Bow housing, from a leak engineer's side
Bow runs from the Victorian terraces around Roman Road and Tredegar Square to large post-war estates and the newer flats around Bow Common and the Fish Island fringe. It is a mix of solid-wall houses with chased-in pipework, council blocks on shared risers, and modern developments using push-fit plastic in stud walls and ceiling voids. Leaks hide here because the terraces conceal decades of unrecorded repairs, the estate risers move water vertically before it surfaces, and in the new flats a partially engaged push-fit fitting can hold then fail inside a void. The damp that shows rarely sits over the fault, so opening the obvious spot usually misses it.
Engineer's note
Bow's spread of stock means we pick the method to match the build. In new flats we assume push-fit in voids and trace where water tracks along joists before opening anything. On estates we correlate the communal run in the duct and clear isolation with management first. In solid-wall terraces we follow chased pipework acoustically, and moisture mapping keeps the opening small and the repair precise.

What fails here
Common leak problems in Bow
01
Push-fit fitting released in a ceiling void
A modern flat near Bow Common had water coming through a downstairs ceiling. Above it, a push-fit elbow in the ceiling void had never fully engaged and finally let go under pressure. The water ran along a joist and dropped several feet from the fitting. We mapped the wet area, traced the run acoustically, and opened one section of ceiling directly over the fault rather than the whole span.
02
Estate communal supply leak in a duct
A council block resident reported damp spreading along a hallway wall shared with the riser cupboard. A communal cold supply in the duct was weeping and soaking the blockwork. We correlated the run inside the duct to fix the position, then coordinated with the estate management to isolate that branch, keeping neighbouring flats in supply while the leak section was renewed.
03
Chased pipe leaking in a Victorian wall
A Tredegar Square terrace had a growing damp stain beside a chimney breast. A copper supply chased into the solid wall during an earlier refit had corroded at a fitting. Because plaster hid everything, previous attempts had guessed wrong. Acoustic tracing along the chase located the leak within a small area, so the repair was targeted and the redecoration minimal.
04
Underfloor heating loop losing pressure
A converted flat with underfloor heating in screed kept dropping pressure and needed frequent topping up. One loop had a fault below the screed with no surface sign. We ran thermal imaging across the floor to map the loop pattern and find the cold anomaly, then confirmed with pressure testing, so only the affected area needed lifting rather than the entire heated floor.
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 Bow — FAQs
How quickly can you attend a leak in Bow?
Same-day appointments are usually available in Bow and across Tower Hamlets, 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 Bow?
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 Bow properties?
Yes — Bow runs from the Victorian terraces around Roman Road and Tredegar Square to large post-war estates and the newer flats around Bow Common and the Fish Island fringe. It is a mix of solid-wall houses with chased-in pipework, council blocks on shared risers, and modern developments using push-fit plastic in stud walls and ceiling voids. Leaks hide here because the terraces conceal decades of unrecorded repairs, the estate risers move water vertically before it surfaces, and in the new flats a partially engaged push-fit fitting can hold then fail inside a void. The damp that shows rarely sits over the fault, so opening the obvious spot usually misses it.
Can you provide a report for my insurer?
Every Bow detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
