Leak Detection East Ham
Hidden water leaks in East Ham pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know East Ham buildings.
Local knowledge
East Ham housing, from a leak engineer's side
East Ham is largely Victorian and Edwardian terraced housing along the streets off High Street North and High Street South, much of it now split into flats or run as licensed HMOs. Nearly every house has a rear back-addition with a shallow lean-to roof over the original kitchen or bathroom, and many have had extra bath and shower rooms fitted upstairs during conversion. Leaks hide in the old buried supply under the ground floor, in retrofit push-fit run through ceiling voids and boxed stair walls, and at the back-addition roof junction. Damp on a chimney breast or party wall is often mistaken for rising damp when the real source is a hidden pipe or a failed roof detail.
Engineer's note
On East Ham terraces I check the back-addition roof, the buried supply and the boxed stack before touching plaster, because so much damp here gets wrongly labelled rising damp. Moisture mapping and acoustic tracing separate a roof or pipe fault from ground moisture, so the repair stays small. In tenanted HMOs I coordinate access with the managing agent and leave an insurer-ready report.

What fails here
Common leak problems in East Ham
01
Back-addition roof junction leaking onto the wall
The lean-to or flat roof over an East Ham back-addition meets the main rear wall at a flashing that perishes with age. Water gets behind it and runs down inside, appearing as damp on the upstairs rear bedroom wall or the party wall. It is routinely blamed on rising damp and treated with the wrong remedy. We trace the actual water path with moisture mapping before any plaster is disturbed, so the fix targets the roof detail, not the plaster.
02
Buried supply pipe leaking under the ground floor
Many East Ham terraces still have the original supply running under the solid or suspended ground floor. A leak here keeps the meter creeping and raises damp in the hallway or front room skirting, with no visible pool anywhere. Digging up floors blind is destructive and often misses. We trace the pipe run and pinpoint the leak acoustically, marking the exact spot so the excavation is a small, targeted opening rather than the whole floor.
03
HMO ceiling void leak between tenanted rooms
In converted East Ham HMOs the added upstairs bathrooms feed through long push-fit runs above the ceilings of the rooms below. One loose fitting soaks a tenant's ceiling and drives the building's water use up. With rooms let separately, opening ceilings on a guess is disruptive for everyone. We locate the run and confirm the fault under pressure, then give the agent a report that identifies the fitting and keeps the repair contained.
04
Failed waste seal behind a boxed soil stack
Conversions often box the soil and waste stack into a stud enclosure in a bathroom or on the landing. When a compression joint or a WC connector behind the boxing weeps, the water tracks down inside the enclosure and shows as damp at the skirting a floor below. Because the pipe is hidden, the source is hard to guess. We test the stack and moisture map the boxing to find the weeping joint before the panel comes off.
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 East Ham — FAQs
How quickly can you attend a leak in East Ham?
Same-day appointments are usually available in East Ham and across Newham, 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 East Ham?
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 East Ham properties?
Yes — East Ham is largely Victorian and Edwardian terraced housing along the streets off High Street North and High Street South, much of it now split into flats or run as licensed HMOs. Nearly every house has a rear back-addition with a shallow lean-to roof over the original kitchen or bathroom, and many have had extra bath and shower rooms fitted upstairs during conversion. Leaks hide in the old buried supply under the ground floor, in retrofit push-fit run through ceiling voids and boxed stair walls, and at the back-addition roof junction. Damp on a chimney breast or party wall is often mistaken for rising damp when the real source is a hidden pipe or a failed roof detail.
Can you provide a report for my insurer?
Every East Ham detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
