About the Service

Found accurately. Fixed without unnecessary damage.

Hidden leaks are easy to misdiagnose. The result? Floors lifted, walls broken open - and the leak still leaking.

HUBB Group's leak detection team uses a combination of non-destructive techniques that allow us to pinpoint the source of a leak without unnecessary damage to your property. Our reports are accepted by every major UK insurer.

Whether it's a slow drip behind a kitchen unit, a central heating leak pushing pressure down every week, or a burst water main under your driveway - we find it first, and we fix it properly.

How We Find Leaks

Three specialist techniques. One accurate diagnosis.

We don't guess. We combine multiple non-destructive technologies to give you a confirmed location before any work begins.

Method 01

Thermal Imaging

High-resolution infrared cameras detect tiny temperature differences caused by water behind walls, under floors and inside pipework - without touching a single tile.

Method 02

Acoustic Detection

Ground microphones and pipe-correlation devices listen for the unique sound signature of escaping water - invaluable for pressurised systems and water mains.

Method 03

Tracer Gas

A safe hydrogen/nitrogen mix is introduced into the system and traced to the leak point with sensitive detectors - the gold-standard method for difficult, intermittent leaks.

Why HUBB Leak Detection

The kind of service insurers recommend.

No Unnecessary Damage

We use detection technology to locate the leak before lifting a single floorboard.

FAQs

Leak detection - the questions we hear most.

Will you have to lift floors or break walls to find the leak?

Almost never. Our entire 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.

Will my insurance cover this?

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.

How quickly can you attend?

We guarantee a 4-hour response for emergencies across Essex and the wider Southeast - most jobs are reached within 60–90 minutes. For non-urgent investigations, we'll usually offer you an appointment within 24–48 hours.

How much does a leak detection investigation cost?

Our standard investigation is charged at our hourly rate. If your insurer is covering the cost, you settle our invoice and reclaim from them. We'll always agree the price with you up-front in writing before any work begins.

Do you fix the leak once it's located?

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.

What if the leak is intermittent?

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.

What areas does HUBB Group cover for leak detection?

We cover the whole of the UK.

How do I know if I have a hidden leak?

The most common signs are an unexplained rise in your water bill, damp patches or a musty smell, the sound of running water when everything's switched off, and a drop in water pressure. A water meter test is a good first check if you're not sure - or just call us and we'll talk it through.

What's the difference between calling a plumber and calling a leak detection specialist?

A plumber deals with what they can see and access. We use thermal imaging, acoustic detection and tracer gas to find leaks that aren't visible - which is why we're often called in after a plumber couldn't locate the source.

Will I get a written report I can keep or send to my insurer?

Yes. Every investigation ends with a written report covering our findings, the method used and photo evidence, formatted for direct submission to insurers.

Specialist Detection Equipment

Pressure testing rigs, acoustic ground microphones and dye testing - used together to pinpoint leaks in pipework, fittings and pool shells.

Pool diver inspection with dye testing

Underwater Dye Testing

Dye is introduced near fittings and liner seams. Any escaping water draws the dye toward the exact point of loss - visible, precise and non-destructive.

Pool plant room pipework inspection

Plant Room Inspection

Pump seals, heat exchangers, backwash valves and filter connections are all checked - the plant room is a common source of pool water loss that is often overlooked.
