Specialist Leak Detection Services

Southern Leak Geeks are trusted water leak detection specialists, serving homeowners, landlords and commercial clients. Our Gas Safe and G3 certified engineers use non-destructive acoustic, thermal and tracer gas technology to pinpoint hidden leaks fast — without unnecessary damage to your property.

How we find leaks

We combine multiple non-invasive technologies to pinpoint leaks with precision — no guesswork, no unnecessary damage.

Acoustic Listening

Sensitive ground microphones and electronic listening sticks pick up the high-frequency sound of pressurised water escaping pipework.

Tracer Gas Detection

A safe hydrogen-nitrogen mix is introduced into the pipework — gas escapes at the leak point and is detected at the surface.

Thermal Imaging

High-resolution infrared cameras visualise temperature differences caused by water leaks beneath floors, walls and ceilings.

Pressure Testing

Isolating and pressurising sections of pipework confirms the presence of a leak and narrows down its location.

Borescope Inspection

Flexible camera probes inspect wall cavities, ceiling voids and ductwork through small access points — no destructive opening required.

UV Dye Tracing

Eco-friendly fluorescent dyes trace water paths through showers, balconies and drainage — visible under ultraviolet light.

Damp Meter Inspections

Calibrated moisture meters map damp patterns across surfaces to confirm active leaks versus historic damage.

Buried Pipe & Utility Location

Electromagnetic locating equipment traces underground water pipes and buried services, helping identify pipe routes and narrow down leak search areas.

Mains Water Leaks

High usage alerts from your water company or sudden drops in pressure often point to a hidden mains leak. Acoustic ground microphones and leak correlation pinpoint the breach — even under concrete driveways.

Boiler Losing Pressure

Topping up your boiler weekly? Thermal imaging and nitrogen-hydrogen tracer gas find the microscopic exit point — with insurance-ready written reports.

Central Heating Leaks

Damp skirting boards, warped floors or cold radiator spots mean a heating pipe leak. Infrared and moisture mapping trace the path back to its origin.

Drain & Waste Leaks

Foul odours or unexplained damp in lower rooms point to cracked waste pipes. High-resolution CCTV surveys and fluorescent dye testing confirm the exact path.

Burst & Hidden Pipes

Ultrasonic leak detectors hear the high-frequency hiss of pressurised water through walls, screed and floor cavities — isolating failures with millimetre accuracy.

Ceiling Leaks

Borescope cameras inspect ceiling voids through existing fittings — no need to cut holes — identifying pipe joints, shower seals or roof defects.

Underfloor Heating

High-resolution thermal cameras map the layout of your UFH circuits and reveal the exact heat bloom caused by a leak — so we only need to lift a single tile.

Dye Tracing

Eco-friendly fluorescent dyes trace water flow through balconies, flat roofs, shower trays and shared drainage — definitive visual proof for insurance claims.
