Specialist Leak Detection Services

Southern Leak Geeks provide expert leak detection services for homeowners, landlords and commercial clients. Our Gas Safe and G3 certified engineers use non‑destructive thermal imaging, tracer gas and acoustic testing to locate hidden leaks quickly and accurately, without causing 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 water usage alerts or sudden pressure drops often indicate a hidden mains leak. Our acoustic ground microphones and leak correlation technology pinpoint the exact location — even beneath concrete driveways.

Boiler Losing Pressure

Constantly topping up your boiler? We locate hidden leaks causing pressure loss using thermal imaging and tracer gas testing — providing fast, accurate results and insurance‑ready reports.

Central Heating Leaks

We locate leaks in central heating systems using acoustic testing, thermal imaging and tracer gas — allowing fast, accurate detection with no unnecessary damage to your home.

Leaking sink waste trap with steady blue‑tinted water drip showing drain and waste leak.

Drain & Waste Leaks

Drain and waste pipe leaks can cause damp, bad smells and hidden water damage. We use dye tracing, CCTV inspection and moisture mapping to accurately locate leaks in sinks, baths, showers suitable for above ground wastes.

Burst & Hidden Pipes

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

Ceiling leak with light blue damp patch and steady water drip.

Ceiling Leaks

Borescope cameras inspect ceiling voids and fittings without cutting holes — identifying pipe joints, shower seals or roof defects with precision.

Underfloor heating pipes with blue leak patch above floor surface.

Underfloor Heating

High‑resolution thermal imaging maps underfloor heating circuits and reveals heat blooms from leaks — allowing repair with minimal disruption.

Angled pipe dripping separate blue and red dye streams for leak tracing.

Dye Tracing

Eco‑friendly fluorescent dyes trace water flow through roofs, balconies and drains — providing clear visual proof for leak detection and insurance reports.
