Read on Trustpilot: the review of Mark by Daniel AngelMark Pavitt came and found a tricky leak underneath the lounge floor. He was courteous, tidy and took his job seriously. I was pleased with the quality of his work and ADI were very speedy in getting an engineer round to help us out.

Read on Trustpilot: the review of Krzysztof by Terry WattExcellent 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!

Read on Trustpilot: the review of Gabor by BenI 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.

Read on Trustpilot: the review of Krzysztof by lei dongVery 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.

Read on Trustpilot: the review of Gabor by Mr Pawan SharmaFrom first contact to final receipt of invoice and report, they have been very professional and extremely helpful.

His persistence was of the highest level and resulted in a positive identification of the issue which he fixed straight away.
