Leak Detection Technology
Hidden leaks can be difficult to trace but with specialist non-invasive technology, experienced leak detection engineers can locate them quickly and accurately, helping minimise disruption to your property.
Why Specialist Leak Detection Matters
Ordinary plumbing tools can’t always locate hidden leaks, especially when they’re under floors, behind walls, or within heating systems. This is where specialist, non-invasive technology helps pinpoint the source efficiently.
Specialist engineers combine advanced diagnostic methods and professional expertise to locate even complex leaks accurately and safely. Each survey is carried out to help minimise damage, support faster repairs, and provide insurer-ready evidence.
Once your water leak is located, a detailed digital report is provided, including photographs, moisture readings, and the confirmed cause of the damage, giving insurers the evidence needed to validate your claim.
The Technology Behind Accurate Leak Detection
Specialist engineers use a combination of advanced, non-invasive tools, from gas tracing and acoustic listening to infrared imaging, to identify leaks in even the most complex systems. Each method is designed to provide reliable results while keeping disruption to a minimum.
These specialist methods are carried out by accredited leak detection engineers coordinated through our team, ensuring evidence suitable for insurance claims.
Gas Trace Technology
A non-toxic, odourless gas is safely pressurised into the pipe system once it’s drained down. The gas escapes at the leak point, rising through floors or walls and detected with precision sensors - even through concrete or tiles. This method is fast, non-invasive, and widely used for reliable leak detection.
Acoustic Leak Detection
Sensitive microphones and listening sticks capture the unique sounds of escaping water with precision. This method is ideal for mains and pressurised systems, detecting leaks even when buried beneath floors or concrete – without unnecessary damage, excavation, or costly disruption.
Thermal Imaging Cameras
Infrared cameras detect temperature differences caused by escaping water beneath surfaces. This enables our team to trace pipe routes, spot moisture spread, and confirm likely leak locations with supporting visual evidence, without lifting floors, breaking walls, or causing disruption.
Endoscopic Inspection
Miniature cameras on flexible probes allow our specialists to inspect hard-to-reach spaces - such as behind walls, under floors, or inside ducts. This visual confirmation helps locate leaks precisely while keeping your property intact and disruption minimal.
Dye Testing
Used only where other methods aren’t suitable, a safe coloured dye is introduced into the plumbing system to reveal the leak’s location. This targeted approach helps confirm complex cases while avoiding unnecessary damage or guesswork.

Super Service
I am an overseas landlord. My tenant’s ceiling collapsed from a bath-mixer leak. APC ran the claim, arranged drying and full restoration, and managed it all while keeping me informed remotely. Couldn’t have done it without them.

Leak Found
Great company to know in a time of difficulty. When no one else could find the leak, they manage to find it in less than three hours.

Excellent
The sudden appearance of ceiling stains was stressful. Leak traces identified the leak and produced a detailed report so the leak could be exposed and repaired. Then their claims team at allpropertyclaims worked with my insurer to approve and cover drying and reinstatement. The whole thing cost me nothing, and my home was back to normal quickly.
Robert Luke - 27 Aug 2025 ★★★★★
Extremely happy with leak tracers! And only wish I had found them sooner. They helped me find an impossible leak. I had first contacted 2 plumbers who tried to find the leak but were not able to. Having wasted money on these plumbers I was advised by my insurer to get a specialist leak detection company.

Truth is, words cannot say just how brilliant a service that Tan and the super APC team provided from initial assessment to sterling completion. Indeed, Tan and the team assured supreme service, professionalism, guidance and support at every stage of my claim and that is exactly what they delivered
Ian Belnikoff - 31 March 2025 ★★★★★
Following the failure of three different plumbers to locate a leak in my bathroom, I made contact with Moez who arranged for an expert to visit my property with specialist detection equipment. The source of the leak was quickly found and a temporary repair effected which required the bathroom floor to be partially
Claim Back Eligible Leak Detection Costs
Did you know that if your insurance policy includes Trace & Access cover, you may be able to reclaim the cost of leak detection? Through our FCA-regulated firm, we can arrange for these costs to be recovered directly from your insurer – provided there’s an insured peril in place.
And it doesn’t stop there. When structural drying is required, the equipment used can consume a lot of electricity. Professionally accredited drying technicians record this usage so these costs can be reclaimed under your insurance policy where cover applies.
