Excellent service from start to finish

Excellent service from start to finish. Caroline was very helpful and informative in the initial call, explaining fully how it worked and what the steps were and then we were lucky enough to have Kristof arrive on the day. He was very thorough, identified where the leak was (under the screed in the living room) and then carried out the repair with minimal mess or disruption. Highly recommended and thank you to ADI!

Kristof was very professional

Kristof was very professional. Explained well what he was going to do at the start and how he expects the job to go. Once he had completed each part of the job he would show what he had found and what was next. Once the leak was found he very quickly fixed the leak to a high level of standard. The area (garden) effect and disturbed by the leak was cleaned and left exactly how it was before the job started, wouldn’t even know there was work carried out. I can’t thank Kristof enough for helping us out. I would recommend him for any job to do with leak detection.

A very efficient and professional…

A very efficient and professional service. Kyle carried out the initial leak detection, he was so polite and professional in his manner. Today the leak was repaired by Kyle and Kristoff, this was carried out with efficency and limiting the disruption to our home, everything explained and left neatly. They were being supervised by a big black lab, Milo who they made a fuss of. Thankyou . Tracy & Abi

Kristof was great

Kristof was great, identified the problem on my ground floor which wasn't easy to find, fixed it, re-fitted the floor impeccably. Not cheap but better to use these guys than some of the other options who waste time and bill by the hour etc. The customer service rep was also very good. Clear comms.

Amazing experience with Kristof

Amazing experience with Kristof, he doesn’t only located the hidden leak fast while informing us at every step but also did a very good job fixing it taking into account the leak was deep down the concrete floor behind our dishwasher, so not a lot of space after taking the cabinets! When he finished the job he left everything as it was! Even vacuumed and moped the mess 🥹 I was very stress about the idea of someone coming and imagined my house upside down at the end of that day… and having two under 3 y/o I couldn’t be more grateful!! Very very professional and highly recommended!

Water Main Leak Repair

ADI came to fix a leak in my water main. The engineer ‘Kristof’ was extremely helpful and answered my questions. He expertly identified the leak, dug the driveway and fixed the problem and put everything thing back well. He then did a thorough job of checking everything. Only criticism is felt quite expensive for the scanning/identification aspect.

Professional leak detection and repair.

Literally the day before we were due to exchange contracts for the sale of our house we received notification from the water company to say they had detected a leak. After several phone calls to companies who were either too busy or failed to appear competent I found ADI were the initial conversation was sensible and reassuring. An appointment was arranged with clear information re cost and what the engineer could do. ADI were able to send an engineer one day early. The engineer Kristof was very professional and soon located the leak. At all stages of the repair Kristof kept us informed and discussed all stages with us when there was risk of damage to units or the floor. He worked quickly and competently leaving the area clean and tidy.

Fantastic service

Fantastic service, Kristof found the leak really quickly and was able to repair it and reinstate the ground leaving it like there never was a leak

Extremely happy with the service

Very happy with the service, the engineer (Kristof) was very tidy and organised, he even helped us move our kitchen units, which shouldn't be his job really. The leak was under the floor, so a hole had to be made to get access to the leak, but the hole was made quite small and carefully, the damage was so much minimum than we expected. A big relief and really grateful we found ADI. Definitely will recommend without a shadow of doubt.

Kristof was great.

Kristof was great. He persevered with a difficult problem and sorted it out. The company charges a lot but in the circumstances it was worth it.

Frank (Ferenc Gulyas) from ADI - top professional

Frank on 1st job day found where is the leak, and also did the internal (inhouse) pipe replacement. Although re 2-nd day job was forgotten to book by ADI (not by Frank), after my call to ADI it was quicky resolved. Based on that Ferenc Gulyas (and Krzysztof Kobylinski) did an excellent job on a 2nd day: all was done in very high professional way, top quality, and after the job was finished making tidy all the access points. Great work, happy customer.

About Krzysztof

Krzysztof came into leak detection through a background in plumbing, heating, and water mains replacement, which means he understands how systems are built before he starts working out where they are failing. On site, he draws on acoustic listening equipment, tracer gas, and thermal imaging depending on what the situation calls for. He covers a broad patch across southern England and the Midlands. Away from work, he is a football fan with a taste for steak, seafood, and traditional Polish cooking.

Frequently asked questions about Krzysztof

What does Krzysztof specialise in?

Krzysztof specialises in central heating leak detection, water mains leak detection, underfloor heating leak detection, bathroom leak detection, drain leak investigation, and underground leak detection. He is particularly known for plumbing and heating work and water mains jobs, including full mains replacement where the pipe has failed beneath a driveway or garden.

How does Krzysztof detect hidden leaks?

He starts with acoustic listening equipment, which detects the sound of escaping water through floors, walls, or ground. Thermal imaging cameras are used where moisture movement is affecting surface temperatures behind tiles or beneath screed. Tracer gas is brought in for buried or pressurised pipe runs where acoustic methods alone are not sufficient, and a borescope camera allows direct visual inspection inside cavities.

What experience and qualifications does Krzysztof have?

Krzysztof has 16 years in leak detection, 16 years in water main replacement, 16 years in internal and external plumbing, and three years as a Senior Water Mains Leak Detection Engineer at ADI. He holds a CSCS Card, Cat and Genny certification, and a digger licence, which covers him for the excavation work that sometimes follows a detection.

What types of properties does Krzysztof work on?

Krzysztof works on residential and commercial properties across southern England and the Midlands. Jobs range from internal plumbing and heating leaks in flats and houses through to underground water mains investigations on larger properties, including cases where the supply pipe runs beneath a driveway, patio, or garden and physical excavation is required after detection.

When should you call Krzysztof for leak detection?

If you have an unexplained rise on your water bill, damp patches appearing on walls, floors, or ceilings, or a central heating system losing pressure without an obvious cause, those are the situations that warrant a professional investigation. Call ADI Leak Detection on 0800 731 3843 to book an investigation and ADI will aim to assign Krzysztof where he is available in your area.

How Krzysztof finds your leak

Krzysztof 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.

  1. Initial assessment. Review symptoms with the customer, check visible evidence, and identify the most likely system involved.
  2. 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.
  3. Non-invasive testing. Run the chosen method across the candidate area — no excavation or destructive investigation until the leak is confirmed.
  4. Leak confirmation. Cross-verify the finding with a second method where possible, mark the exact location, and document the evidence.
  5. Reporting and next steps. Provide a written report, photographs, and recommended repair options.
