Reviews by the type of leak

Excellent service

Excellent service. Simple as that. Contacted them about a leak in our central heating system and they explained their process for investigating to find it. Hamaad came out with all the equipment and had located the suspect area in less than an hour and it was all fixed and checked out really quickly after. It might seem like a high price for this service but it really minimises the amount of upheaval this type of problem can cause. ADI, and particularly Hamaad, you’re a star!

Thorough, professional and tidy

Impressed. Our engineer, Robert, showed up on time and got started on finding the leak. Our boiler had been losing pressure, and although we suspected a leak in the lounge, we needed confirmation (and we also needed to know there were no others). He found the leak, checked the rest of the house, dug into our concrete floors (with minimal mess) and replaced two lengths of copper pipe. He was thorough, professional, tidy and explained what he was doing throughout. He also made sure we saw exactly how and where the old pipes had failed. A good experience and glad to have it sorted.

Perfect from start to finish

Robert arrived on time and was very polite and respectful of my property. He answered all the many questions I had and explained everything he was doing whilst doing it and next steps. We had a leak in the heating system - boiler kept dropping pressure -Once he drained the heating system he pumped some air and then gas. He found the leak almost immediately in a very hidden place inside our built in wardrobe! Robert is very thorough and will definitively ask for him if I have the same problem again (but hopefully not!!) thanks Robert you saved us a lot of £££££

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.

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!

James is an asset to ADI-pipe leak/fix

James arrived on time, used high tech equipment to locate leak, then fix pipe leak, ensuring carpets etc covered. He then went above and beyond to fix an air lock and get my boiler, pressure and radiators going again, which wasn't straight forward. Also referred to concept to help deal with insurers for ceiling repair. Very friendly, professional and efficient, he is an asset to ADI!

Very Happy customer

ADI and in particular Mark Pavitt were brilliant. We had a particularly tricky situation where a builder had installed underfloor heating, completed the kitchen on top and then a leak was discovered. Mark was very polite and extremely thorough and patience working through all the various variables to find the issue. So happy its fixed and would certainly recommend.

Failed Push Fit Cap = Underfloor Leak

The engineer, Mark Pavitt was very personable and his technical skill and knowledge was very good, explaining everything in detail throughout the process. The leak was fixed with minimum disruption to the floor area, which turned out to be a failed push fit connection to a previously removed radiator. I would recommend to others

Great leak detection company

The engineer, Mark, arrived and very quickly found the leak in the floor of my downstairs toilet. He was extremely professional and took the time to explain the whole process clearly, which really put my mind at ease. He patiently answered all my questions and even spoke to my insurance company on my behalf, which I found incredibly helpful. The leaky pipe was fixed, and Mark left the area clean and tidy. There’s still more work to be done but the main source of the problem is resolved. Thank you, ADI for a very good service,

Brilliant service

Mark was brilliant, he thoroughly assessed the situation, checked in a very uncomfortable crawl space under the property and actually located the leak (something Southern Water have failed to do 3 times). Bless him, he worked very hard in some extremely challenging weather, but most importantly he found & fixed the issue on the day. We cannot thank him and ADI enough, after three long years we are now able to sell my late mothers property safe in the knowledge there is no more leak.

Super speedy and efficient service

From the initial telephone conversation to completion of the leak detection and fix, ADI really know what they are doing. Initially I had a good conversation about what to expect and how to deal with insurance. Then the engineer, Mark Pavitt was great. He kept me informed of the time he would arrive and when here, located the leak and fixed the pipe very quickly. Really friendly, helpful guy and a very efficient service. All sorted and very happy customer. Would definitely recommend. Thanks.

Brilliant!

What a brilliant company and Gabor who attended was fantastic, he was so professional and efficient , listen carefully to me whilst I a non plumber(!) tried to explain the issues, he worked diligently to locate the issue and then solved it, I could not recommend the company more, from my first phone call they worked efficiently and did exactly what they said they would do, Gabor arrived on time and solved the problem. Thank you Gabor for being a star.

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.
