Leak Detection Chiswick
Hidden water leaks in Chiswick pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Chiswick buildings.
Local knowledge
Chiswick housing, from a leak engineer's side
Chiswick is dominated by handsome Victorian and Edwardian terraced houses, many with original features and rear extensions. Plumbing is often a mix of old lead supply lines and newer upgrades for en-suites and kitchen remodels. High ceilings and suspended timber floors provide access but also long, vulnerable pipe runs. Loft conversions add complexity with new heating circuits.
Engineer's note
A dripping sound under floorboards needs same-day investigation; slow leaks here cause structural rot.
Covered in Chiswick
- Hidden leaks under floors and in walls

What fails here
Common leak problems in Chiswick
01
Lead Supply Pipe Leaks
The original lead communication pipe from the mains to the house is a frequent failure point, often leaking underground near the boundary. This causes unexplained damp patches and can significantly increase your water bill.
02
Leaks Under Original Floorboards
Pipework running under suspended timber floors can leak for weeks before signs appear on ceilings below. Warped floorboards or a musty smell are often the first clues, by which time significant timber rot may have set in.
03
Extension Plumbing Stress
Single-storey rear extensions often have new pipework tied into old systems. Differential settlement between the old house and new extension can stress these connections, causing leaks at joints.
04
Tank & Cistern Overflows
Many older properties retain traditional cold-water tanks in the loft. A faulty ball valve can cause constant overflow, often unnoticed until it soaks through a ceiling or causes staining on an external wall.
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 Chiswick — FAQs
How quickly can you attend a leak in Chiswick?
Same-day appointments are usually available in Chiswick and across Hounslow, 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 Chiswick?
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 Chiswick properties?
Yes — Chiswick is dominated by handsome Victorian and Edwardian terraced houses, many with original features and rear extensions. Plumbing is often a mix of old lead supply lines and newer upgrades for en-suites and kitchen remodels. High ceilings and suspended timber floors provide access but also long, vulnerable pipe runs. Loft conversions add complexity with new heating circuits.
Can you provide a report for my insurer?
Every Chiswick detection visit can produce an insurer-ready trace and access report — cause, precise origin, methods used, moisture map and photos — typically within 48 hours.
