Leak Detection Finchley
Hidden water leaks in Finchley pinpointed without opening floors or walls — acoustic, thermal imaging and tracer gas detection with no find, no fee, from engineers who know Finchley buildings.
Local knowledge
Finchley housing, from a leak engineer's side
Finchley features a high concentration of the extended 1930s semis, where rear kitchen and bathroom additions have created complex plumbing layouts. Original pipework often runs under these newer extensions, making leak access challenging. The area also includes substantial Edwardian terraces near the conservation areas, where original features remain but plumbing ages. Modern flat conversions in larger period homes add another layer of multi-occupancy plumbing systems.
Engineer's note
For Finchley's extended semis, we provide insurers with schematics showing original vs. added pipework, clearly establishing pre-existing risk factors for claim validation.

What fails here
Common leak problems in Finchley
01
Leaks Under Conservatory Additions
Many semis have conservatories or orangeries added over original ground-floor pipe runs. Leaks here often go unnoticed until damp appears, requiring careful trace and access to avoid unnecessary structural damage. We document the pipe route and leak point with minimal intrusion for insurer approval.
02
Shared Drainage in Converted Flats
Large period homes converted into flats often share old clay drainage runs. A blockage or leak in one flat's waste pipe can affect multiple units. Our CCTV surveys precisely identify the shared section and fault, essential for insurers apportioning costs.
03
Corroded Tank Feed Pipes in Lofts
In properties with original cold water tanks, the galvanised steel feed pipes in the loft space are prone to corrosion, especially where insulation traps moisture. We trace leaks back to these often-overlooked sections, providing evidence for full system upgrades.
04
Faulty Isolating Valves in Kitchens
Kitchen refurbishments in extended semis often install cheap isolating valves on dishwasher and washing machine feeds. These frequently fail, causing slow leaks behind integrated units. We identify the specific valve failure for the insurer's parts-and-labour claim.
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 Finchley — FAQs
How quickly can you attend a leak in Finchley?
Same-day appointments are usually available in Finchley and across Barnet, 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.
