Leak Detection and Fix
Called up to report a pipe leak between the meter and house and the individual the other end was very helpful and had someone out to us within 24 hours which was lucky. Gabor the engineer was very competent and located the problem quickly, which included digging up an area of driveway, replacing some pipework and putting everything back again properly. He even replaced our dodgy stopcock for us. Excellent job.
★★★★★

Engineer Gabor was excellent. Very thorough and left the house as he found it. Highly recommended.
★★★★★
A job well done
A job well done. The engineers, Kristof, Gabor and Vincent, turned up when expected and made sure excavated areas were made safe before they left. It was a 3-day job and I was kept informed throughout. They were efficient and respectful and everything was made good at the end. A thank you too to Dave in the office for his efforts.
★★★★★
Leak detected and resolved, great service!
Gabor was friendly, professional and efficient. Gabor explained the process throughout and was able to locate our leak and replace where the leak was. When we had a similar problem previously other plumbers ripped up all the tiling in the bathroom which then needed replacing.
★★★★★
Professional, efficient and effective service
Very helpful and professional from first contact with the call centre through to the plumber sorting the leak. Extremely prompt service - they came the very next day, which meant we didn't have to do without heating over the weekend! The plumber, Gabor, was very informative, keeping us abreast of what he was doing, and why, throughout the process. He found the leak, repaired it, and our central heating is now back in business. Thank you!

Rob was fantastic he arranged for a visit that same day to track and trace where the leak came from. Their engineer Gabor was very meticulous,knowledgeable and professional.would highly recommend. Thank you Rob & Gabor for your excellent service
★★★★★
Fabulous leak detection and repair service
Having had another leak detection firm charge me a fortune to try and tell me there was no leak ADI came to visit today. Gabor our engineer was brilliant and located the leak within a couple if hours under the floor in the hallway. He then dug out the area and replaced the area of pipework solving our problem. This has been going on for months, I only wish we had found ADI earlier. Highly recommended.
★★★★★
Excellent service
From first contact to final receipt of invoice and report, they have been very professional and extremely helpful. The engineer that attended (Gabor) was very thorough and explained every step he was undertaking to resolve the issue. His persistence was of the highest level and resulted in a positive identification of the issue which he fixed straight away.
★★★★★
Gabor really went above and beyond
Gabor really went above and beyond to find what was a very unusual and difficult leak. To save my newly tiled floor he took up the floor in an under stairs cupboard and climbed under the suspended floor to detect and fix the leak. I know this company is more expensive than some others, but it was worth it.
★★★★★
Multiple leaks found and fixed
Gabor worked hard across a long day and (hopefully) found and fixed all our leaks. He was professional, polite and patient.
★★★★★
I can highly recommend ADI
I can highly recommend ADI. Our engineer Gabor was brilliant, located the leak, fixed it and was very pleasant to deal with. Super impressed as we were really worried we had a major situation. We probably did, it's just these guys sorted it.
★★★★★
I will be recommending them to everyone.
Everyone we dealt with throughout the process just seemed so friendly and legitimately caring about our situation. Things did NOT go to plan for us in the beginning, but Gabor came and sorted the leak out with with a very professional, patient, and methodical manner which made us feel very reassured (as well as his colleague Mark). Dave in sales kept our expectations managed and also proceeded to provide support, an ear to whinge into, as well as practical and thoughtful solutions to the problems we faced. They persevered and solved our problems with incredible expertise - I really don't talk about many companies being truly good and helping their clients, but ADI is a company I will keep in mind for the long term whenever anyone I know has a leak issue. Really feeling grateful for their service and although you pay for specialist support, it truly is a case of you get what you pay for and then some!
★★★★★
Fantastic service from everyone at ADI!
Fantastic service from everyone! Gabor especially, who came out and was professional, friendly and very efficient! He had the leak identified in no time and fixed shortly after! Phew!! I had visions of my garden and patio walkways having to be dug up but luckily the leak was close to the water meter. Well done ADI!
★★★★★
Gabor was trustworthy and courteous
Gabor was very courteous, he explained what he was going to do and after I had explained the history he proceeded with his investigations. He removed his shoes, every time he was in the house (our boiler is in the garage) and on finding the leak demonstrated his findings and gave us options for resolving the leak. I'm a Chartered Engineer so I would have spotted any nonsense but he was as straight as a die, very trustworthy. Thank you Gabor.
Gabor started out in plumbing and heating, progressing into water mains replacement, power flushing, and eventually specialist leak detection. That background means he understands how water systems are built, not just how they fail. Away from work, Gabor is a PADI Master Diver — a qualification that also makes him one of the few ADI engineers equipped to carry out underwater swimming pool leak investigations directly.
Frequently asked questions about Gabor
What does Gabor specialise in?
Gabor specialises in central heating leak detection, underfloor heating, water mains, underground pipework, bathroom plumbing, drain investigation, and swimming pool leak detection. He has spent 4 years focused specifically on swimming pool leaks, making him one of a small number of ADI engineers with dedicated pool investigation experience backed by a PADI Master Diver qualification.
How does Gabor detect hidden leaks?
Thermal imaging cameras detect heat variation through walls, floors, and ceilings, allowing Gabor to identify a likely leak area without opening anything up. Acoustic listening equipment picks up the sound of water escaping from buried or concealed pipes, while tracer gas is used on pressurised systems to pinpoint a precise fault. Borescope cameras and moisture meters are used where physical inspection of a confined space or damp reading is needed to confirm findings.
What experience and qualifications does Gabor have?
Gabor has 26 years in plumbing and heating, 7 years in leak detection, and 4 years in swimming pool leak detection. He holds an NVQ Level 3 in Plumbing and is a qualified PADI Master Diver, which supports his underwater pool investigation work.
What types of properties does Gabor work on?
Gabor works on residential homes, commercial buildings, and properties with swimming pools. He handles relatively routine jobs such as bathroom and central heating leaks as well as more demanding investigations involving buried water mains, underground pipework, and underfloor heating systems where the leak source is not immediately visible.
When should you call Gabor for leak detection?
If your water meter is running when all taps are off, you have unexplained damp patches, a consistently cold radiator circuit, a rising pool water bill, or a drop in pressure on an underfloor heating system, an investigation is worth booking sooner rather than later. Call ADI Leak Detection on 0800 731 3843 to arrange an investigation — ADI will aim to assign Gabor where he is available in your area.
How Gabor finds your leak
Gabor follows a consistent five-stage process on every visit. The approach is non-invasive and designed to isolate the fault before any disruption to your property.
Initial assessment. Review symptoms with the customer, check visible evidence, and identify the most likely system involved.
Selection of the right detection method. Pick the combination of thermal imaging, tracer gas, acoustic listening, or moisture mapping most likely to isolate the fault.
Non-invasive testing. Run the chosen method across the candidate area — no excavation or destructive investigation until the leak is confirmed.
Leak confirmation. Cross-verify the finding with a second method where possible, mark the exact location, and document the evidence.
Reporting and next steps. Provide a written report, photographs, and recommended repair options.
