We don't guess. We combine multiple non-destructive technologies to give you a confirmed location before any work begins.
High-resolution infrared cameras detect tiny temperature differences caused by water behind walls, under floors and inside pipework.
Ground microphones and pipe-correlation devices listen for the unique sound signature of escaping water.
A safe hydrogen/nitrogen mix is traced to the leak point with sensitive detectors - the gold-standard for difficult, intermittent leaks.
Five ways we find and resolve leaks in Great Dunmow - from everyday plumbing leaks to full insurance trace & access claims.
We trace central heating leaks accurately, without draining or dismantling the whole system - the right fix for a system that keeps losing pressure.

A leak detection test (sometimes called a leak detection survey) is a non-destructive investigation used to pinpoint the exact source of a hidden leak before any repair work begins. Our engineers combine thermal imaging, acoustic detection and tracer gas to confirm the leak's location, then provide a written report with photos - typically completed in a single visit.
We combine three non-destructive techniques: thermal imaging cameras detect the temperature differences caused by escaping water, acoustic devices listen for the sound of the leak through walls and floors, and tracer gas traces slow or intermittent leaks that are harder to find. Together these methods confirm the exact leak location without needing to lift floors or break into walls.

There is no single piece of equipment that finds every leak. That's why our engineers use a combination of thermal imaging, acoustic leak detection and tracer gas technology to locate hidden leaks quickly and accurately. By selecting the right method for each property, we can pinpoint leaks with minimal damage, saving time, reducing unnecessary excavation and providing clear evidence for insurance claims where required.
Almost never. Our approach is built around non-destructive detection - thermal, acoustic and tracer-gas methods locate the exact point of the leak so that any access required is minimal and targeted. If access is needed for the repair, we discuss and quote for it before lifting a single tile.
Most home insurance policies include "trace and access" cover specifically for leak detection. Our reports are formatted for direct submission to insurers and we'll handle the paperwork for you. If you'd like us to liaise with your insurer directly, just let us know.

Yes. The same team that diagnoses the leak carries out the repair, so there's no handover, no waiting for another contractor and no risk of the diagnosis getting lost in translation.
Intermittent leaks are our speciality. Tracer-gas detection in particular is highly effective for slow, occasional or pressure-dependent leaks that other companies struggle with.
