If you’re experiencing damp patches, mould, musty smells, dripping noises or unexpected increases in water usage, you may have a hidden water leak. The Leak Hunter provides fast, accurate and non-destructive water leak detection Harrow, helping homeowners, landlords and businesses prevent serious structural damage.
Using advanced diagnostic technology, we trace leaks in walls, ceilings, floors, bathrooms, underground mains and concealed pipework — without unnecessary disruption. Once located, we can also carry out all required repairs.
How We Detect Water Leaks in Harrow
Thermal Imaging
Infrared cameras detect temperature differences behind walls, floors and ceilings, helping reveal hidden water pathways.
Acoustic Leak Detection
Sensitive listening equipment identifies vibration signals caused by escaping water within pipework and structural voids.
Tracer Gas Testing
A non-toxic tracer gas mixture is introduced into the system. It finds the leak and is detected using specialist gas probes.
Moisture Mapping
Moisture meters measure damp levels throughout the structure to track how far water has travelled.
Endoscopic Camera Surveys
Slimline cameras provide internal views of wall cavities, pipe boxing and voids with minimal disturbance.
Hidden Leaks
Hidden leaks often form:
- Behind plasterboard
- Beneath flooring
- Inside wall cavities
- Within service voids
Signs include persistent damp smells, discolouration, peeling paint, boiler pressure loss or increased water bills.
Ceiling Leaks
Ceiling leak symptoms include:
- Brown or yellow stains
- Bubbling or flaking paint
- Dripping or intermittent leaking
- Sagging plasterboard
These leaks typically originate from pipe joints or bathrooms above. We locate the exact source quickly.
Bathroom Leaks
We trace bathroom leaks from:
- Shower trays
- Bath seals
- Toilet waste pipes

- Concealed pipework
All investigations are handled with minimal impact on tiles and finishes.
