Under floor heating leak

ADI Leak Detection came out to find the leak in my under floor heating, the technicians name was Gabor, the leak in our under floor heating really was challenging to find, Gabor is very experienced and was the right person for the job, after a lot of different equipment and brain power, he located the area to dig, found and repaired the leak, he is very good at his job, I would thoroughly recommend Gabor and ADI Leak Detection.

Our engineer Frank

Our engineer, Frank arrived at the arranged time exactly.
We found him to be very pleasant and polite.
He worked very hard to detect the leak, which he eventually found to be in the boiler.
He explained everything very clearly to me and then spoke to our heating engineer on the phone to inform him of his findings.
He left after 4 hours of thorough investigation then sent me videos of his findings later that evening.
We could not fault either Frank or Joe in the ADI office for their work.

Above and beyond

Phil came out to find a water leak, tested thoroughly and found a leak outside our boundary. Water board found the same, but sent a team who didn't investigate properly and declared there was now no leak. Phil came back, dug up my drive to prove the leak was outside my boundary, he spoke to water board on my behalf and the water board finally fixed the leak. Phil was great - really went above and beyond to help me. Excellent service.

Fantastic service by ADI and their engineer.

My initial call to ADI was just for a quote and timeframe, the person I spoke to was extremely knowledgeable and clear about the work and costs. After a bit of arranging (and being let down by another company) I decided to go ahead with ADI. I was in contact with a lady called Caroline who was very friendly and accommodated my date availability, avoiding my birthday, for the work to go ahead. The engineer who attended was a lovely man name Artur, he was on time, which is sometimes a rarity these days, and even thought struggled to find the leak initially he never gave me any doubt that he could fix it. With leak fixed, he gave me advice on next steps to rectify the damaged caused by the leak and made the area he worked in neat and tidy before he left. I would fully recommend this company and Artur.

Leak in central heating system

I called ADI after experiencing pressure drops on my boiler and after my plumber confirmed the boiler was functioning normally I suspected a leak. I spoke to Dayan who arranged my appointment and was very helpful and professional, he explained the process fully and what I should expect on the day. Paul was the plumber who arrived on the day and he was very helpful and extremely thorough, after a few hours of testing and a lot of patience he finally located and fixed the leak with minimal damage to my flooring. I hope I don’t require leak detection services again, but if I ever do I will be going back to ADI.

Would not recommend

Initial telephone conversation failed to inform us that a small leak would be difficult to find and as turned out was impossible to find. Call handler was told how much water loss we had and assured us they would find it. Left with feeling like we have been scammed out of £770.
Would not recommend or use again. Ok

Dear Carole,

We are disappointed and concerned to read your feedback.

Unfortunately, at the time our tests were carried out, our equipment proved the leak to be even smaller than the rate that was reported at the time of taking the booking, and indeed outside of detectable parameters.

We have tried to make contact with you multiple times to address your concerns, discuss your report, and ways of moving forward with this problem, but we have not received a response.

We would have appreciated being given the opportunity to address your concerns before receiving a negative review. Nonetheless, we are still very keen to communicate with you and give you some assurance that we are not scammers. That is of course not how we want our customers to feel.

Please respond to our calls/emails if you would like to discuss further.

Kind regards,

ADI Leak Detection.

Excellent service from Mark Pvaitt ADI

Just had Mark Pvaitt from ADI come out to do an emergency leak in our home. He was absolutely excellent, was very knowledgeable and clearly very experienced. Detected a leak in our hot water pipe under our flooring. Nothing was too much and was here until late evening to make sure job was done. Very friendly and polite, couldn’t recommend any higher

Two leaks found and fixed.

Had a leak somewhere in the house. Artur was the plumber who came out. He was prompt and professional. He actually found and fixed 2 leaks in the house. One was under the kitchen floor and very difficult to find. He explained everything as he went along.

Top job, very impressed

I had a central heating leak that was driving me nuts. Two plumbers couldn't find and suggested I pull my LVT flooring up. I called ADI and am so glad I did. From my initial phone call and speaking to Caroline in the office to the final fix was efficient, pain free and effortless. Brett, the engineer arrived on time and set about with his array of instruments and tracked and confirmed the leak. Everything was explained and I witnessed four different instruments confirming his findings. Brett, was very friendly and professional. Taking care of my property and minimising the area of floor to be lifted. All in all, I'm throughly impressed with company and Brett's skills. I would have no hesitation in recommending them.

It sounds like you had a particularly tricky leak case! We are so glad that you called us as well, and that Brett was able to locate the leak using non-invasive methods and minimising damage to the floor. That is the aim of our game!

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!

Professional and efficient.

The engineer turned up promptly and started work straight away. The nature of the job meant that it was not straightforward and it took a while to locate the leak. He carefully cleared the area, cut out a section of pipe and made the repair, explaining the situation to me, what had caused it and made preventive measures to avoid further issues. He took time to refit as much as possible and then tidied up after himself with a lot less redecorating needed than I anticipated.
I was very happy with the work done and professionalism of the engineer. My wife is just happy to have the heating working again!

Excellent work

We have just had Hammad out and he was fantastic. He rang me yesterday to confirm the booking and arrived right on time. He was very professional. He was also very friendly and easy to talk to. He managed to locate our leak which was under the concrete in our kitchen floor. He told me right throughout what he was doing and why. He fixed the leak and did a very thorough job. He cleaned up after he was done and I can't recommend him enough. I would be happy for him to do jobs in my house again any time.
