Water Mains Leak Detection Specialists

Fast, Accurate Water Mains Leak Detection for Homes and Businesses

Noticed low water pressure, an unexplained increase in your bill, or damp patches on your property? It could be a leak in your water mains, the underground pipe that connects your property to the public supply. These leaks are often invisible from the surface but can cause extensive and expensive damage over time.

We specialise in detecting underground water mains leaks quickly and accurately, using advanced equipment to avoid unnecessary disruption.

Underground Leaks Are Hard to Spot, But Expensive to Ignore

Your water main runs from the boundary of your property to your stop tap. If it leaks, water seeps into the ground silently, wasting hundreds of litres a day and potentially undermining driveways, paths, and even your building’s foundations.

You might not see any obvious signs. But what you will notice is pressure dropping at taps, damp or cracked areas outdoors, or a water meter that never stops spinning. Every day it’s left untreated raises your water usage, repair costs, and risk of structural damage.

We Locate Hidden Leaks Without Damaging Your Property

We use specialist tools to find the exact location of a leak without having to dig anything up. That includes sensitive listening equipment to hear water escaping underground, tracer gas to help us spot leaks in tricky areas, and tools to track where your pipes run. If there are signs at the surface, we can also use thermal cameras and moisture tests to help pinpoint the problem.

This means we don’t have to guess or dig up large areas. Once we’ve found the leak, we’ll mark the spot so it can be fixed quickly and with minimal mess

Signs You May Have a Mains Leak

Don’t wait for flooding or property damage. Call us if you’ve noticed:

A higher than normal water bill with no clear reason
Low water pressure throughout the property
Constant sound of running water with all taps off
Water meter movement even when no water is being used
Unexplained damp patches, cracks or sinkholes outdoors

Our team can carry out quick tests to confirm whether the problem is coming from your underground pipework even if you’re not 100% sure.

Are You Responsible for the Leak?

If the leak is on your side of the external stop tap — usually within the boundary of your home or business — then yes, it’s up to you to repair it. That’s why quick detection matters.

Not sure? We can help clarify where your responsibility starts and whether you can pass the issue on to your water supplier.

Can You Claim This on Insurance?

If your buildings insurance includes Trace and Access cover, you may be able to claim the full cost of leak detection. Most policies will reimburse you for finding and accessing the leak, even if the repair itself isn’t covered.

We’ll provide the exact documentation insurers ask for, including images, readings, and technician notes formatted to meet industry standards.

What Happens During Your Survey

Every leak detection visit follows the same structured process, so you know exactly what to expect and what you’ll walk away with.

1. Arrival and walkthrough.

Your named technician arrives in a branded vehicle at the agreed time. We walk through the property with you, noting every area of concern such as damp patches, pressure drops or visible damage, so nothing is missed.

2. Non-invasive testing.

We deploy the right combination of tools for your situation, including thermal imaging to map moisture behind walls, acoustic listening to trace pressurised leaks, tracer gas injection for underfloor pipework, and moisture meters to measure the extent of saturation.

3. Source identification.

We isolate the leak to its precise origin point and confirm the cause — whether it’s a failed joint, a corroded section, a cracked fitting, or external water ingress. We photograph the evidence and explain our findings on-site so you’re never left guessing.

4. On-site debrief.

Pipes inside walls and under floors can crack or shift due to building movement, temperature changes, or old age. Because these leaks are entirely out of sight, they tend to do the most damage before they’re found. A small split in a pipe behind plasterboard might release water 24/7, soaking timbers and insulation without any outward sign until serious damage appears .

5. Written report delivered

Within 48 hours you receive a detailed PDF report by email. This is the document you forward to your insurer, your plumber, or your landlord. It contains everything listed below.

Your report includes

Confirmed leak location with annotated photographs
Identified cause (e.g. failed solder joint, cracked compression fitting, degraded pipe section)
Thermal images and moisture readings showing the affected area
A clear written summary of findings
Recommended next steps for repair
Technician name, qualifications, and date of inspection
Insurer-ready format accepted by all major UK home insurance providers

FAQ's

Our most frequently asked questions.

How do I know if I have a water mains leak?

Signs of a water mains leak include an unusually high water bill, damp patches in your garden or driveway, reduced water pressure, or the sound of running water when no taps are in use.

Where do water mains leaks usually occur?

Water mains leaks typically occur in the pipe that connects your property to the main water supply. These pipes often run underground beneath gardens, driveways, or paths.

Can you detect underground water mains leaks?

Yes. Specialists use advanced leak detection equipment such as acoustic listening devices and tracer gas to locate underground leaks without unnecessary digging.

Will my garden or driveway need to be dug up?

In most cases, no. Leak detection equipment helps pinpoint the exact location of the leak first, meaning only a small area may need to be accessed for repairs.

Who is responsible for repairing a water mains leak?

If the leak is on the pipe within your property boundary (the supply pipe), it is usually the homeowner’s responsibility. Your local water company is responsible for the public mains in the street.

What happens after the leak is located?

Once the leak is found, you’ll receive a report explaining the location and cause of the issue, along with recommendations for the necessary repair work.
